Caterpillar chain

FIELD: transport.

SUBSTANCE: proposed caterpillar chain consists of separate interjointed tracks. It comprises stiffness element and has holes in track links. Stiffness element is enclosed by elastic enclosure. Inner volume of link holes is filled with low-density material. Outer link surface facing soil is wide in its central part and narrow on edges to form vertical rubs-grousers along the edges.

EFFECT: higher shock-absorbing properties and reduced weight.

Scope

Caterpillar (B62D 55/18, B62D 55/205, B62D 55/253, B62D 55/24) is intended mainly for use in lightweight tracked vehicles, including sequential (one after another) position of the track Assembly and the second support (ski, caterpillar) and managed the creation of lateral inclination of the surface - when handling the bike.

The level of technology

Famous traditional caterpillar, which contains the individual links, interconnected flexibly and(or) the hinge and forming a track chain (tape) is given in the textbook for high schools "Tractors and automobiles" Amigurumi, publishing house "spike", M, 1983, str.

Caterpillar has a flat (ploskoreznyh) profile base (main) surface of the links in the cross section of the caterpillars from the outside (facing the ground) side, which made the lugs. Such transverse surface profile links with the outside prevents easy carrying significant lateral tilt when riding on ATVs single-track layout, the track does not have cushioning properties for greater comfort.

The disadvantage of caterpillars is its heavy weight and wasteful use of the material.

The prior art patent RU 2131370 on the links hingeless segment caterpillar vehicles is a, which are made with grooves to accommodate the elastic closed-loop tape on which they are mounted, and internal supports placed in its Central zone of the elastic strips. The caterpillar is equipped with an air bag mounted on the outer surface of the element, and a closed air-chamber ribbon, representing the two glued together along the lateral sides of the elastic band with the formation of the closed airspace in which two coaxial with each other axes hingeless caterpillars.

Disadvantages caterpillars are its weight and the wasteful use of the material.

The prior art patent US 2005173983 on rubber caterpillar. Rubber track contains elements of rigidity in the longitudinal direction of the belt at the edges of the openings through which threaded the ropes, envelopes each element of rigidity on both sides and connecting links between them.

The disadvantage of caterpillars is its heavy weight and wasteful use of the material.

The closest analogue is the patent EP 0326279 having the same connection cables, as in the solution according to the patent - US patent 2005173983, but each element of the caterpillars is rigidly connected with the adjacent, and the appointment of rope - making of elasticity this connection.

In addition, to reduce the weight of the modules caterpillars and the cost of consumption is the materials, the links on the caterpillar contain one or more apertures of arbitrary size.

The disadvantage of this solution is that the caterpillar is molded, and cast. Therefore, it is impossible to assemble the parts and to repair some of the individual link. In addition, the holes in the links during operation easily clogged, and all the advantages of weight reduction caterpillars are lost.

The technical result of the present invention are increased cushioning properties and reduced weight, insensitivity to punctures and damage, as well as the exclusion of securemote holes in the links.

Brief description of drawings

Figure 1 shows a General view of the site crawler belt with two links. Figure 2 is a longitudinal section and side view in section of caterpillars and links, where 1 - link caterpillars, 2 - wire (ribbon), connecting links, 3 - element stiffness level caterpillars with plasmolysis base, 4 - shell of elastic material (rubber and the like), 5 - insert (core) of the elastic, relatively soft material of the reduced (low) density, 6 fastening member attached to the element stiffness (nut-rivet), 7 - guide comb caterpillars, 8 - bolt (screw) for fastening the guide element to the element stiffness and the link caterpillars.

Disclosure of inventions

The claimed technical cut ltat is achieved (see Figure 1 and figure 2)that the caterpillar that contain certain links (1), interconnected and form a track chain (tape)containing the element stiffness (3) parts, the holes in the links, characterized in that the element stiffness (3) enclosed in a shell (4) of elastic material, and the internal volume of the apertures of the links filled with a relatively soft material of relatively low density material parts and (or) their shells. Such material preferably should be capable of elastic deformation is typically more than 10% to restore the original shape and volume during operation. To accomplish this, the material can be made with the possibility of elastic deformation of more than 10% and restore the original shape and volume during operation.

Another variant provides that the units contain an internal cavity (volume)filled with a relatively soft material of relatively low density material parts and (or) their shells, for example, in the form of element insertion. The cavity is isolated and has no external access to the surface level. It is different from the hole and has the advantage that isolated from contact with the external environment, which excludes any impact on the material of low density.

This provides the caterpillar elevated mortization properties and reduced weight insensitivity to punctures and damage, and also prevent clogging of the holes in the links.

The element stiffness (3) can be performed with plasmolysis base, located near the inner surface of the caterpillars. This helps to reduce the rolling resistance of rollers on the inner surface of the chain links (1).

In the element stiffness (3), in the longitudinal direction of the belt edges can be made holes through each of which is threaded the rope (2) and/or the rope, and/or tape, envelopes element stiffness (3) on both sides and connecting links (1) between them. This helps to ensure a reliable connection cables (2) (feeds) with links (1) due to the force of friction that occurs when passing a rope through the holes and bend.

The outer facing the bottom surface of the links (1) can be made wide in the Central part and made constricted at the edges so that it forms a vertical rib-lug design on the edges. This allows you to increase the traction force due to the lateral vertical lug having greater rigidity. Also the outer profile of the outer surface of the links in the cross section of caterpillars can be made convex to facilitate lateral tilt when riding.

The stiffening elements can be assigned to a separate non-removable fastening elements (6), issue Lennie with the possibility of fixing them guide elements (7) crest caterpillars and/or resistant elements for interaction and engagement with sprocket wheel track Assembly. This provides a more robust connection elements caterpillars (guides combs, etc. with links. For more durable fastening of the guide element (7) to the element stiffness and the link caterpillars can be used bolt (8) (screw).

Separate fastening elements (6) can be made in the form of nut-rivet installed on plasmopara the basis of element stiffness, and its hollow base above the surface of the parts so that an additional support and a guide for the fastening elements of the caterpillar.
