The invention relates to wheel circuits designed to provide traction grip wheeled vehicles (such as cars and trucks), moving, for example, by snow or ice. More precisely, the invention relates to circuits having so-called "diagonal" cross elements, and, in particular, circuits in which at least the s in the adhesion to the surface of the earth.

Known removable auxiliary safety devices to provide traction with the ground (the ground surface) wheels cars. In some such devices, at least the cross-work items (i.e. items that crosses the tread of the wheel tires) are in the form of a chain or flexible cables, which are based on power elements (elements clutch) tires wheels. Also known, though less common, wheeled detachable auxiliary safety devices, in which components that interact with the road surface to run in set (grid) bars, rods and so on, closed up in a "picture" of the elements of the clutch protector, more or less evenly distributed on the tire of the wheel. Despite the diversity of these devices in practical aspect completely relevant remains to develop improved their designs with improved performance, more simple in Assembly and disassembly, more acceptable in the sense of control for different conditions of operation, durability, versatility (adaptation under the tires of various sizes) and other PA is th invention the base variant of the new chain contains an elongated inner side element, forming when installed in a working position a circle of a certain length around the rim of the wheel of the car with its internal side.

And in Fig. 17 shows a detail view of the hold the inner side of the cable for the circuit shown in Fig. 10.

As shown in Fig. 1, the circuit 10 constituting the first embodiment of the invention, includes an elongated inner side working element 12, which has a fastening elements 14A, 14B, located at its ends, and a lot of the transverse elements 16 forming a zigzag diagonal grid or grating 18, the opposite ends 18A, 18B which are suitable to the respective fastening elements mounted on mycause the said inner element and distributed along it, as well as the set of external nodes 22 mates, located on the opposite side opposite to the inner side of the element. Internal nodes have the connectors 24, through which the transverse wire elements lug fastened to the inner side of the element at a given position on the latter. The structure of the considered circuit also includes tensioning means 26 for delays external nodes to the axis of rotation of the wheel with the provision of an adjustable gap between adjacent nodes.

In the present embodiment, as the inner side of the element uses a flexible cable type that is typically used in cable snow chains. The fastening elements are connected to each other, forming a lock (grip) 14 shown in Fig. 2. In the design of this lock may include a plate part 28 having a contour in the form of hooks or Ushkov 30A, 30B and gripping the stub portions 32. In coupling parts 32 are attached to the ends of the inner side of the rope. In ears 30B and plate parts under them there are openings 34, which are inserted in the hook 36. The transverse elements 16 on the ends of the chain are attached to the plate elements under consideration of the castle. When connecting the specified elements cu is VCE chain on the wheel forms around the rim of the latter with the inner side of the circumference of a given length. This circle is closed joined elements of the hold, as shown in Fig. 2.

In Fig. 3 shows one of the connectors 24 for fastening the inner junction of the transverse elements of the chain from the inner side of his rope. The design of this connector includes a plate part 38 having a limb in the form of a bracket 40 and the gripping sleeve 42, which is compressed by the above-mentioned lateral wire 12. The ends of the pair of adjacent transverse elements 16 forming the internal node 20 mates, bonded to the connector 24, which connects the node with the inner side of the rope, as shown. In Fig. 3 illustrates one way of fastening the transverse elements with the connector. In this embodiment, at the end of each transverse wire is fixed earring or ear 44; these earrings when the Assembly is inserted into the spline grooves 46 in the bent lip (and/or plate-wall) connector, whereupon the lip bends upward, as shown in Fig. 3, locking (clamping) earrings connected cross members between the bent part and the body plate part 38. A similar device for the connection of the transverse element with a lateral lug element is described in U.S. patent N 4366850, the owner of Kotor is relatively connector with adjustable angle of convergence in the node. Further, this design allows you to easily replace the transverse elements: it is enough to straighten the bracket, remove damaged transverse element and insert a new one, by bending back the lip of the connector.

Each transverse element at the end of the zigzag mesh can be attached to the respective plate parts 28, shown in Fig. 2, in exactly the same manner as in the connector shown in Fig. 3.

As follows from the consideration of Fig. 4 and 5, the transverse elements 16 of the circuit containing the load-bearing rope section 47, which are equipped pulling the coupling elements in the form of rollers 48. These rollers are preferably made in the form of spiral wound springs. The carrying cables of the transverse elements can be braided in the form of a coiled wire 50. In some cases, the rollers may not be used: in these cases, the traction will be created directly by cables, which can be closed from outside the wire braid. In principle, instead of rollers can be used with the coupling elements of other types.

As shown in Fig. 1, external hosts 22 convergence of the transverse elements of the chain are fastened to the connectors of two different types. The connector 52 of the first type shown is whether 56B and bent lug or bracket 58. The ends of each pair of consecutive cross members forming the node, can be bonded together using a connector of this type, as shown in Fig. 3. This connection allows you to adjust the angle of convergence of the transverse elements in each connector and is easy to replace them (the replacement method was discussed above in relation to the connectors 24).

As follows from Fig. 1, the adjusting means (device) 26, a part of the circuit design consists of three sections 26A, 26B and -26 C, in the form of cables associated with the external nodes of the pair of transverse elements. In some cases, it may be used less or more than three such units (with a smaller or greater number of external nodes). However, the use of three or more cable segments is preferred, because this design has certain advantages, analyzed below.

One end 60 of the cable of each link is fastened to a connector 52 (see Fig. 4) using a fold, welding or in some other appropriate way. The cable link is skipped then moving through subsequent connector 54 as shown in Fig. 5. For this purpose, the connector 54 has a sleeve 62, which passes through the cable link.in the form of a continuous tubular parts, for example, of nylon.

At the free end 64 of each cable link has several successively spaced relative to each other buckles or stub nasdaw 66 secured by crimping or some other way. These clamps when installing the chain on the wheel is passed through the slotted hole 68 in the base plate 56A, resting on the frame 70 (see Fig. 4), and the stubborn fixation can be selectively engage one or the other of the clamp, depending on the required degree of tension. With this device you can change the working length of each link in the form of a cable. This design is intended to regulate the effective length of the cable, also described in U.S. patent N 3752204, which is owned by the author of this invention. From the analysis of Fig. 4 it follows that each connector to which a removable securing the free end of one cable link, serves simultaneously for rigid fastening of the end of the next link in the form of a rope. Optionally, the end 64 of each link can be performed by locking the focus, the locking end of the cable in the hole of the connector 52 and thus preserving a given installation the length of each such link.

Part of the external nodes 22 mates rigidly fixed in position on the outer side element by means of the connectors 52, and the portion of such nodes (intermediate nodes) is assigned with the possibility of sliding movement of the connectors 54. With this design decision, every external node is regulated by the position of the circle relative to the neighboring external nodes, but due to the fact that some (many times) the nodes are fixed on pescecane chain wheel (even under hard acceleration and braking).

Next with reference to Fig. 6-8 describes how to install the chain on the wheel.

For this purpose it is necessary to Park the car, turn the engine off and engage the Parking brake. In the car front-wheel-type steering wheel must be rotated so that the front wheel was located. Then you should spread out on the ground circuit as shown in Fig. 6, with the smooth side of all its connectors should be facing upward (or to the side of the wheel at the location of the connectors on the line side bus), and the free ends of the three cable links released. Further, the circuit should lay on the ground so that one of the free spaces 80 in the outer side element coincided with the wheel. One transverse element should be at the front wheel, and the other (following) this item for him. These transverse elements must have freedom of movement. Then captured the opposite ends of the inner side of the element and disposed up in a comfortable position so that you can connect the fastening elements (castle) 14A and 14B.

After installation of the inner side of the wheels mentioned inner side of the element in the form of a fully zamknutoj is 52 (see Fig. 4), starting from the level, near to the wheel. Initially, the effective length of each cable link left more necessary, however, in the future, all these links are tightened to the required length, moving from link to link in the direction, for example clockwise around the wheel, resulting circuit will completely cover the wheel. In some cases, to ensure a snug fit of chain to the appropriate wheel, grasping the transverse elements, pull them off and move the chain in different directions.

Manual chain tension is best done by moving one of the bushings 66 from one hold to another external lateral element until then, until the chain is not stretched sufficiently (when checking manually). After tightening the chain at this position of the wheel should move the car to tighten the other cable links. Upon completion of the tightening torque (tension) chain her rope links should be approximately the same length. However, under certain conditions in the process of mounting the circuit may not be possible realization of equal length wire segments without moving the car. With this in mind, for one of the links may be required uvelichena slippage of the cable links on the relevant connectors 54, primary fixation of one of the links can be implemented, in fact, due to "borrowing" the tension of one or more other units; in this case, the transverse grid elements will initially be uneven. The ability to engage the cable links under such conditions is a characteristic of this circuit. This grid will become uniform after moving the car and podregulirovan length cable links so that it was approximately the same. Protruding free ends of the cable links are fixed by means of clamps 74 (see Fig. 4).

Instead of the cable inner side member can be made of rigid (semi-rigid) spring tape in the form of a Hoop or ring binder. This brace is shown schematically position 82 in Fig. 10. In this embodiment, circuit elements fastening the ends of the tape bandage is made in the form of a simple hook 84 and lug 86. For the separation of adjacent connectors internal nodes can be used in the intermediate nozzle tube 88; in this case there is no need in fixing the internal junctions of the transverse elements on the tyre moulding or some other way. It is also possible fixes on the circuit using the modified connectors.

The following is an analysis of the principal distinguishing features and advantages of the present invention. The length of the inner side of the element is not adjusted, the length of his castle should be minimal. Under this condition, when installing the chain on the wheel, the circle formed by the inner side element may be set at a specified distance from the rim, preferably within two inches (50 mm) beyond the rim of the wheel regardless of the size of tires, and will not have hardcoresex noticeably long plots in attachment points on the ends of this element. This design eliminates or minimizes problems related to free up space on the inner side of the wheel, in particular for brake means. Further, the use of unregulated hold (lock) to the inner side of the element simplifies and accelerates the installation of the chain on the wheel.

The inner side of the chain end transverse grid elements formed by the combination of these elements, are fixed near the ends of the inner side of the element. When the connection ends of this element cross members at the ends of the said grid, will come together, forming near the castle in the elements of. As a result, if you install the chain on the wheel throughout the generatrix of the surface of the tire is formed a uniform grid of transverse elements clutch with almost constant pitch (cells) of these elements and without heterogeneity characteristic of known circuits longitudinal and diagonal configurations.

The distribution of internal nodes connected along the length of the inner side of the element is fixed. Respectively, is constant and the interval (pitch) along the circle between these nodes after you install the chain on the wheel. This ensures the uniformity of the transverse elements of the clutch on the bus and simplifies the mounting of the chain.

Fixing positions on the circumference of the three external nodes in the connectors 52 in the first embodiment, the circuit also promotes a uniform fixed transverse distribution of elements in the mesh, preventing the gathering of these items in the grid, preventing the gathering of these items in one place when braking or accelerating and jumping circuit with wheels under hard acceleration or deceleration of the vehicle is in motion. However, the interval between successive external nodes is self-regulating in the process impudently tension and adjust the chain on the outer side of the wheel. Cross the coupling elements are assembled in pairs, so that their number in the formed grid even. Due to the hinge action at the nodal connectors, tension transverse elements is implemented in the mode of individual self-regulation. The force applied to the lateral elements from the transverse elements are transmitted not directly, but through intermediate hub connectors. The tangential components of the forces applied to each connector of each pair of associated transverse elements and acting on the circle, opposite direction and almost compensate each other.

Application connectors-adapters between the transverse elements of the clutch and the lateral retaining elements eliminates the problem of broken connections in nodes characteristic of known circuits. In addition, due to specific decision nodes fastening the ends of the inner side of the element, and conditions of transmission from the transverse elements at the ends of the mesh to the fastening elements of the inner side of the element eliminates the possibility of rupture of the latter in the bonding area (castle).

The present invention provides a number of advantages compared to the currently used diagonal CEPA the practice. In particular, it is essential uniformity, homogeneity zigzag diagonal grid of transverse elements of the claimed circuit, providing a more uniform and stable grip the wheel with the ground, as between the road surface and the tread is always some cross-element chain. In known circuits this is impossible, since the intervals between the transverse elements in the grid do not remain unchanged, which is a consequence of the displacement of their ends in the operating conditions or predetermined design solution mentioned grid cells which vary along the longitudinal size when the connection ends of the side elements.

In the circuit of this invention, the transverse elements creating traction, are arranged diagonally, forming a mesh grid. This prevents Zapadnye these elements and their retention in the transverse grooves of the tread pattern that may negatively on the condition of the tires and the chain. When diagonal arrangement of the transverse elements of the chain links more evenly distributed on the wheel, create less noise and vibration, to a lesser extent beyond the working surface is about placement in the seat, at the same time reducing the wear and tear of the transverse elements. A side benefit is that the diagonal elements move smoothly under the tire in contact with the ground during rotation of the wheel.

Proposed in the framework of this invention, the circuit not only provides improved adhesion of the wheels with the ground, but the increase in speed on a slippery surface for extended life. The use of a solid cylindrical roller clutch elements on the diagonal chains leads to wear and tear on the type of "top". As shown, this problem is eliminated in full when used on a diagonal transverse elements of the rollers in the form of spiral springs. In addition, due to the uniformity of distribution of the transverse grid elements on the tire, the wear of these elements accumulate relatively uniformly across the grid, and not in a separate characteristic points, which ultimately increases the service life of the chain. This effect is enhanced by the tension and adjusting the position of the individual transverse elements with the resulting adjustment of the load. This circuit operates in the mode of full dynamic balance, which contributes additionally to the lengthening of the term of its services is arnosti damage to the circuit due to other features of its design decisions being a principal advantage of the invention.

Overly stretched condition known circuits is an essential prerequisite for their break. At the same time, if the chain is installed on the wheel is too loose, the cross, the work items may strike the bottom of the car, causing damage to its parts and the chain. In contrast, the proposed circuit can be easily mounted to provide the necessary degrees of freedom of rotation of the wheel in a variety of tires, and if we consider the chain and is set excessively tight, it will not cause damage to the tires.

Circuit forming the subject of the claims of the present invention are "generic" devices, working well on the tyres of various types, including low-profile and other modern tires.

As follows from the above stated circuit provide significant benefits to the user. They preferred (compared with known circuits) and for the producer and the seller. When the corresponding item data set of circuits of different sizes it is possible to "cover" them a much greater number of types and sizes of tires than when using the known circuits. Next, norazlina sizes (regardless of the size of the tire). Thus the presence of three typical internal lateral elements of different lengths can be installed in a total of seven standard rims of different diameters. The width or diameter of the tire determines the length of the transverse elements, however, since the transverse elements are mounted on the side of the wheel, and their tension is implemented outside the bus, actually there is a significant range in the length of the transverse elements.

For a given length of the inner side of the element and at a specified rim diameter the length of the transverse elements may be selected so as to ensure adequate their fastening on the outer side of the wheel at a different size tires. Each length of the inner side of the element may correspond to, for example, two or three lengths of the transverse element. Positive practical result is in particular that for all passenger car tyres can be used only eight sizes of chains. This is a significant advantage for sellers and producers (in the sense of reducing the range of products).

One of the advantages discussed above for the first variant of the claimed circuit is that the sides of the t to consist of 1/8-inch (3.2 mm) wire rope 7x7, and transverse elements of the 1/8-inch cable CH. The cable may have a coating (for example, vinyl or nylon) or not to have coverage. Cross cable can be braided in the form of a spirally wound wire, as mentioned previously, although this will increase the weight and torque forces on the transverse elements. In the General case, rope chain is more lightweight, easier to fit when in use and easier to install.

Below you will see other versions of the invention, with the majority (if not all) of the advantages of the first option discussed above. Except as stipulated below, the circuit design for each of the following modified version (in particular, the inner side of the element cross-section elements, connectors internal nodes and elements of the clutch) is the same as in the first variant.

The second variant of the proposed circuit is shown in Fig. 11. In this embodiment, the outer side part of a chain runs from the chain sections 90 adjustable length. Opposite ends of each section are connected to a closed hooks or rings 92, pivotally attached to the connectors 94 external junctions. On one of the links of each of the districts. The hook 96 to prevent its disengagement from sodastream link 98 may be worn strictly small elastic sleeve or nozzle 100. After appropriate adjustment of the length of each of the sections 90, in collecting these sections form the external side of the element that pulls the connectors 94 in the direction of the axis of rotation of the wheel, creating tension transverse elements 16.

As shown in Fig. 12, each of the connectors 94 external nodes, shown in Fig. 11, may be made in the form of a plate part 102 with unbent outward eye 104 and the stub contour 106, similar to the design shown in Fig. 3. However, in this case, the sleeve 106 forms a bearing surface under the ear hook 108 and 110, which passes through the opening 112 in the plate 102 with sufficient freedom so that the hook could swivel to rotate in the specified hole, settles at different angles. When using the connectors 94, shown in Fig. 12, in the variant shown in Fig. 11, the protruding portion 114 of the hook is closed at its longitudinal rod portion 116, forming a ring that holds the end links of the chain sections.

In Fig. 13 shows a variant, which is a modification of the second option. In this modificirovana is 118, which is fixed to the elongated continuous inner city elastic element 120. Thus the chain sections are subjected to tension, transmitting transverse force elements 16 through the connectors 122 external sites. The connectors 122, shown in Fig. 13, have a modified construction in which the applied ring 124 passed through the stub limb 106. With ring 124 are connected end parts of adjacent chain sections 117.

In Fig. 14 shows the third embodiment of the invention. In this embodiment, the chain tension transverse elements creates an elongated continuous elastic element 126 fastened with hooks 128 connectors 130 external junctions. The design of the connector shown in Fig. 14, there is no stub limb 106, characteristic for the connector shown in Fig. 12, although in principle, such a coupling part can be used. In addition, instead of a single hook 128 of the plate part 132 of each of the connector 130 can be executed at the same time is a flat hook, gear said elastic tension element.

In the fourth embodiment, consider the circuit shown in Fig. 15, the elastic tensioning element 126 is replaced by a jumper 134 is adjustable the n end of this jumper can have a termination loop 136, dockable in the power ring 92' one of the connectors external sites. The plane of the ring 92' perpendicular to the plane of the ring 92. In the ring 92' may hold the hook 138 buckle 140, through which the free end of the jumper allocated to squeeze back with adjustable length of the latter. These buckles are widely used in practice. It is obvious that the outer side of the element, if necessary, may be implemented in part of elastic material and partly of rigid jumpers.

Connectors external nodes of this type, as shown, for example, in Fig. 12, in which the hook is connected with the plate body movably articulated, are preferred, with the advantage that it does not interfere with samosatene (automatic tension) accompanying the transverse elements and compensate for the weakening of the tension that can occur when the wheel spins. Such connectors are desirable in particular when the composition of the tensioning device includes an elastic element, so as elongation of the latter will be accompanied by a weakening of the tension of some of the transverse elements. More precisely, during the rotation of the chain wheel transverse elements, the front end of which is connected to vnutrennyaya to bend back. This tendency is enhanced by the disposition of the rollers of the clutch in such transverse elements to be displaced in the direction of the front end of these elements.

To compensate for unwanted tension relieving transverse elements which may occur during rotation of the wheel, it is desirable that the connectors external junctions could be rotated about the hinge from the hooks. In other words, it is desirable that these connectors are reacted on the strength (degree) of the tension accompanying cross-section elements, turning on their hooks. In this sense, the optimal pivot connection, and an effective compensation of the strain relief will be provided when the triangle bounded by the vertex point of the hinged connection of the hook with a connector of the external node and the points where two transverse element of the chain is bonded to the connector will be equilateral; under this condition, swivel angle spread will be about 30o. If the point hinge fixing to move closer to the axis of rotation of the wheel, the above triangle is isosceles, which will lead to a decrease in the maximum angle of the hinge pivot, which however is by modification of the fastening means 14 of the inner side of the element, it is shown in Fig. 2. In this modified construction the end part side of the rope 12 passes through the stub limb 142 of each of the fastening element 144A, 144B and bent back to form a loop or bend 146. Sleeve 142 is compressed on the rope. The end of the rope fastened to the plate 148 of the hold with legs-jumpers 150, vyshtampovannyj on the plate and objetych around the end of the rope, as shown in Fig. 16. Sleeve 142 is formed on the edge of the plate body 148. On the opposite end of the plate 142 bent lug 151. This lug or bracket has a hole 153 in which is inserted the end of cross member 16, which is fastened to a plate item 148 in the manner discussed previously with respect to Fig. 2. The opposite ends intermediate the hook 152 is connected by hinges 146 fastening elements 144A, 144B (one end of the hook is in the form of closed loops), closing around the circumference of the inner side circuit element. Fixing the site shown in Fig. 16, has a very high tensile strength and reduced abrasion in the joined parts through the use of the hook (which is less exposed to the abrasive action than sheet metal). In order to further weakening of abrasive damage to the s outside cast nylon plates, interacts with the hook 152. The positive quality of the mount shown in Fig. 16, is that all of the tension force (the force vector applied to the parts of this site) are almost in the same plane and intersect at a common point, which provides a high kinematic stability of the mounting system.

In Fig. 17 shows the mount 154, designed as a lock-hold for a wire spring-Obrucheva inner side of the element 82, shown in Fig. 10. This node consists of two fastening elements 154A and 154B connected with the ends of the wire Hoop 82. The fastening element 154A has a flat hook 156, which is inserted into the hole 158, closing around the circumference of the Hoop 82. Bent up ears 160 have slotted holes 162 that is used to secure the ends of the transverse elements 16, for example, by the method shown in Fig. 16. Each fastening element has a sleeve portion 164 through which are passed the corresponding end of the tightening Hoop. This end of the sleeve part 164 unbent aside loops 160 and clamped to the latter. Thus, each end portion of the Hoop is sewn together with the element-sacrapos 154A or 154B due to compression under the, is provided in Fig. 17, all the vector forces of the tension will be approximately in the same plane, intersecting at a common point. An additional advantage and positive quality is that the mount is fixed from the reversal of the plane of the Hoop.

In conclusion we should draw attention to the fact that the above private variants of the invention are purely illustrative, not excluding the possibility of entering into the construction of the inventive circuit modifications and improvements, practical content and acceptable volume of which will be determined by the provisions of the claims below.
