The level of technology

Similar to the disc brake described in the publication EP 1936227. This publication applies, in particular, to a method of Assembly of the disk brake, in particular, Assembly converts the movement of the cartridge, which is converted into the aswat rotational movement of the brake lever in the forward movement of the brake piston to turn off or deactivate the Parking brake.

In the known construction the rear part of the cartridge contains a pin mounted in the slot in the bottom of the slot, intended for installation of the cartridge in the cylinder bracket brake. This design is relatively complicated to manufacture and installation, and the pin when the Parking brake is exposed to significant torque forces.

The objective of the invention

The task underlying the present invention is to simplify the manufacture of the bracket brakes, reducing the number of parts in the composition converts the movement of the cartridge, and to reduce the cost of manufacturing staples.

Disclosure of the invention and its advantages

To this end offered a disc brake of the type specified above, characterized in that:

A) transforming the movement of the cartridge (transducer motion) is:

And1) back, resting in the bottom slot of the cylinder and includes:

- support in the form of a sleeve with a flange resting in the bottom of the socket around is made in the bottom of the through-hole through which partially passes sleeve, and

a control shaft connected to the Parking brake lever and provided with a first disk;

And2) the front part, rests on the brake piston is installed with the possibility of translational movement relative to the cylinder, but recorded from provor is zivania about it and includes:

the push comes with a second disk that interacts with the first drive shaft control by moving balls located between the sloping surfaces of the two disks, for converting the relative rotational motion between the two disks in the forward movement of the pusher,

- ring (casing) that is holding the plunger in the cylinder by a spring clip,

- return spring located between the yoke and the plunger for resisting forward movement created by the disks and balls;

B) the cylinder at its rear end forming a socket for transforming the movement of the cartridge has at least one longitudinal groove and the plunger has on its periphery (side surface) of the longitudinal protrusion, the cross section of which corresponds to the cross section of the longitudinal groove to communicate with the groove and fixing the front part of the Chuck from turning with the freedom of its translational movement.

Thus, retention of the plunger, i.e., the movable nut inverter movement, from turning (fixation of rotation) is achieved directly on the bracket without using the intermediate parts, since the fixing of the rotation is provided by a pair of longitudinal protrusion or protrusions located on the front is the second part of the cartridge, with a longitudinal groove or grooves made in the nest cartridge in the clip.

Accordingly, a significant advantage of the invention is the exception to the design of the rear casing of the cartridge, and a pin mounted in a hole in the bottom bracket of the rear holder from turning.

In accordance with the invention, the yoke rear part of the famous cartridge replaced with a simple back support with L-shaped profile in longitudinal section. The exception cage rear improves the draining of the brake circuits, i.e., conducive to drain the brake fluid, as proposed in the invention converts the movement of the cartridge does not contain any components with closed cavities. This simplifies the manufacture of the shroud and reduces the length of the cylinder, or the notches in the bracket in which is located the bullet.

The invention also simplifies the Assembly of the cartridge, which is conducted in the framework of the technological process of Assembly of the brake, eliminating the use of special equipment to receive the cartridge Assembly. The clip is not already latched on the back of the Chuck body, which eliminates the risk of the formation of burrs.

Finally, the invention can be implemented in relation to the pistons or plungers of a smaller diameter than the pistons or plungers, currently used, with the same set up, if appropriate the most of their efforts.

In a preferred embodiment of the invention the slot of the cartridge in the clip has three longitudinal groove, and a plunger provided with three longitudinal tabs (terminals), wherein the longitudinal grooves are evenly distributed around the circumference of the socket, i.e., are arranged at equal angular distances from each other, and the protrusions are respectively the location of the slots.

These three longitudinal groove in cooperation with three longitudinal protrusions provided on the plunger of the cartridge, perfectly keep the plunger from turning, while allowing you to avoid the problems associated with considerable torque that can be applied to the plunger by means made in the form of a ball transfer connection between the disks. This excellent fixation from turning also favors the reverse movement of the pusher when you turn off the Parking brake.

In yet another preferred embodiment of the invention at least one longitudinal groove of the socket has the contour of the cross section in the shape of an arc of a circle, in particular in the form of a semicircle, and a longitudinal protrusion on the plunger has the contour of the cross section in the shape of an arc of a circle, identical to the arc of a circle cross-section of the groove. The slots and tabs of this form is very simple in manufacture, in particular for the implementation of ka is Dogo groove by mechanical processing.

In another preferred variant of the invention, the longitudinal protrusion is made in the form of a rod, passing backward from the second disk and covering the rear part of the cartridge at least part of its axial length.

The length of the longitudinal protrusion, which is, therefore, oblong execution is the rod (crest), especially when there are multiple longitudinal protrusions formed on the plunger, which is preferably equal to three, perfectly provides the direction of movement of the plunger, i.e. the smoothness of the forward movement in the slots as guides, and fixation (from turning) of the pusher in the bracket. Rods, bent back, allow to reduce the axial length of transforming the movement of the cartridge, and not to the detriment of the quality of the direction of movement of the pusher, especially because the rods are supported in surround them free space as a back support, and a disk on the shaft of the control cartridge. In these conditions, even the impact on the rods significant efforts cannot squeeze the rods from their grooves, because the rods are held in the slots and locked there due to the presence of the rear part of the cartridge.

In yet another preferred embodiment of the invention the nest cartridge has a shelf made to stop him contour of the shroud, and the outer groove, made under the spring holder.

In yet another preferred embodiment of the invention the clip is a product made of elastic steel, made in a generally conical shape and having a base in the shape of the crown, from which emerge the petals are connected to the rim and located between the intermediate petals of the adjacent their free ends with spring holder.

In yet another preferred embodiment of the invention the clip is a product made of elastic steel, made in a generally conical shape and having a base in the form of a ring, from which emerge the petals are connected to the rim, and an intermediate petals having free ends and mating with spring holder.

Such holder and its interaction with one hand, with the ledge, and on the other hand, with the County groove in which is located a spring holder, provide excellent stopping converts the movement of the cartridge in its slot by a geometric circuit and rigid attachment of the cartridge to the housing bracket. This stopper reliable and can not open spontaneously. To open it you will need a special tool, such as a sleeve acting on the ferrule conical shape for the gradual release of petals clip that provides the take split the rim and release it from the groove. Installation is carried out in the same conditions by performing actions in reverse order.

In General, disc brake equipped with such a transformative movement cartridge, easy to manufacture and assemble due to the small number of parts. The invention provides an excellent functioning brakes and ensures its reliability.

The implementation of the invention

To simplify the description proposed in the invention of the disk brake as longitudinal orientation adopted the axial direction along the axis x-x shown in Fig.1, and to the left in the drawing is the front side, and the right rear side is on, so that the brake piston front side face to the brake pad, and back to the slot in the bracket. Similarly, the front part which converts the movement of the cartridge is on the side of the brake piston, and the back - side of the bottom of its slot in the bracket.

In Fig.1, 2A and 2B depicts the disk brake 1, associated with the hydraulic brake system and the control system Parking brake. Floating bracket 100 covers the brake disc 2 and is provided with a fixed block 3 and the movable block 4, i.e., is the backbone for these pads. The movable block moves the brake piston 5 located in the cylinder (or the housing 110 of the bracket 100. The cylinder 110 restricts hermetically isolated chamber 111 connected via inlet 112 to the circuit of the brake system, not shown. In this hermetically isolated chamber 111 is transforming the movement of the cartridge 200 (Fig.2A, 2B), resting in the bottom 114 of the slot 113 in the cylinder bracket. A slot 113 is a continuation of the cylinder 110 to the brake piston. In the bottom 114 nests made the hole 115 through which hermetically displayed end of the cartridge 200 (Fig.3) for providing the transmission of motion connection with the lever 120 of the Parking brake, which is connected with the governing body Parking brake and rotational motion (rotation) of which the conversions is conducted in a progressive move, transmitted to the brake piston 5.

Converts the movement of the cartridge 200 shown in Fig.2A-5, has a rear portion 210 and the front part 260.

The rear part 210 formed T-shaped in longitudinal section, a support 211 containing the sleeve 212 of the flange 213. The sleeve 212 is located in the hole 115, made in the bottom 114 of the bracket 100, and its flange 213 rests on the bottom surface 114 surrounding the hole 115. Bearing 211 is supplied with o-ring 214, which provides a seal gap between it and the hole 115, and it is the shaft 220 management formed a cylindrical part 221, ending in front of the first disk 222. The cylindrical part 221 passes through the sleeve 212 supports 211, speaking to the rear of the bracket so that it could be fixed arm 120 of the Parking brake. The disk 222 abuts against the flange 213 of the support 211. In the front surface of the disc 222 is made of a groove of variable depth, designed to interact with the balls 230, which is installed in the holder 231 and which are in the same conditions interact with the plunger 270, installed with the possibility of forward movement.

The front part 260 converts the movement of the cartridge 200 includes a plunger 270 formed by the sleeve 271, fitted behind the second disk 272, the surface of which is made of the groove 273 of variable depth, complementing on your the situated and shaped grooves of variable depth (not visible) in the first drive shaft 222 220 management. Rolling balls 230, the number of which is equal to, for example, three, matching the grooves of the drive shaft 222 220 management and disk 272 pusher 270 rotational movement of the drive shaft 222 220 control is converted into reciprocating movement of the pusher 270 through additional interaction of the inclined surfaces formed by the grooves, as is in itself known. The front part 260 converts the movement of the cartridge also includes a spring 280 compression, mounted on a cylindrical sleeve 271 of the plunger and resting, on the one hand, in the disk 272 pusher 270, and on the other hand - in the base 291 clip 290, also mounted on the sleeve 271 of the plunger 270.

The clip 290 is a product made of elastic steel, made in a generally conical shape and having a front ring that forms the basis of 291 exited the petals 292, United in pairs with the two parts of the split facing outward flanges 293, and the intermediate petals 294 having free ends. Spring holder 201 is installed in the holder 290 petals around 292, 294 and between them to hold the cartridge 200 in the socket 113, made in the bracket 100. To install the clip split the rim 293 and spring holder 201 in a known manner squeeze through a tool in the form of a sleeve. Spring holder 201 holds the ferrule 290, EOI is imagestwo with the wall of the circumferential groove 118, and the split rim 293 is placed in the slot 113 to rest on the ledge 117 in the bracket 100, as provided by the build process described in the publication EP 1936227 that the above link. Thus, the cartridge 200 is held in its socket 113 from moving in one direction at the expense of the rest split rim 293 in step 117, and from the offset in the opposite direction by a spring holder 201 is fixed in the circumferential groove 118, so that the freedom of movement have only the shaft 220 management and the plunger 270.

The plunger 270 (Fig.4, 5) has one or more longitudinal protrusions, which in this example is made in the form of rods 274 extends from the disk 272 ago. These rods 274 with a semicircular cross-section slide in the grooves 119 of the corresponding cross section is made in the wall of the slot 113 of the bracket 100 (Fig.3) in positions corresponding to the arrangement of the bars. In the preferred implementation, there are three rod 274 located at equal angular distances, i.e., uniformly distributed in the circumferential direction, around the axis x-x slot 113. Thus, the plunger 270 is installed in the slot 113 with fixation from turning, but with the possibility of forward movement. The rods 274 cover, or cover, the rear portion 210 of the cartridge at the level of the edge of the disk 222 and the flange 213 of the support 211. The disk forming the holder 231, in which is placed the balls, also held (radial offset) rods, which is important for manufacturing Assembly, which is transforming the movement of the cartridge, and greatly facilitates the installation of the cartridge in the slot 113.

After installing the cartridge 200, the shaft 220 of the control and drive 222 have a rotational degree of freedom, so that rotary motion of the shaft 220 of the control leads to a rotation of its drive 222 relative to the disk 272 integral with the plunger 270, causing the plunger 270 is reported translational movement transmitted to the brake piston 5.

The plunger 270 is adjacent to the back of the brake piston 5 by means not shown in the drawing, the wear of the brake pads, located in the plunger 270 and forming the nut as the threaded element of the pair having an internal thread. Compensation for wear of the brake pads is known to the specialist, by extension nuts when released the Parking brake.

The cartridge 200 is composed of a small number of parts and is a pre-assembled unit ready for installation in the recess (slot) in the bracket brake 100. Such installation of the cartridge does not preclude the subsequent installation of a brake piston and not difficult, and does not violate subsequently draining the fluid from the braking system.

The front part of the cartridge rests against the brake piston. The named part of the cartridge includes a pusher fitted with a disk interacting with a control shaft disk by means of balls located between disks with a possibility of rolling along the paths designed as inclined surfaces for the conversion of the rotary motion of one disk with reference to another into the translational movement of the pusher. The cartridge is locked in its seat by a yoke resiliently pressed against the seat wall. The pusher disk has longitudinal grooves interacting with lock cores and thus holding the pusher from rollover with ensuring freedom of its translational movement.

EFFECT: simplification of fabrication of the brake bracket due to minimising of the quantity of parts of the movement conversion cartridge is achieved.

SUBSTANCE: annular disc brake includes a rotating disc and at least one disc shoe installed on each side of the rotating disc. Brake shoe or shoes on one side are connected to an axially guided load-carrying element of the brake shoe. The brake has a force transfer mechanism creating enhancement of increase in force between the axially driven element and load-carrying element. The method for increasing gripping force of brake shoe in annular disc brake consists in the fact that the first force is generated synchronously with the brake drive; at that, the first force has the direction that is parallel to rotation axis of the rotating disc. Also, rotating torque is generated using the first force; at that, rotating torque has the rotation centre that coincides with rotation axis of the rotating disc. Besides, the second force is generated using rotating torque; at that, the second force has the direction that is essentially identical to the direction of the first force and is higher than the first force. The second force is used for gripping of brake shoes on opposite sides of the rotating disc.

EFFECT: increasing brake compactness and providing uniform distribution of braking force in a circumferential direction of the rotating disc.
