Caterpillar chain / 2373098

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.

Endless caterpillar track for wheel-caterpillar vehicles / 2381944

Endless caterpillar track comprises endless flexible member supporting multiple flexible-material spaced apart elements, grousers. Said endless flexible member represents at least two wire ropes, spaced apart for axial size of sprocket-type caterpillar drive element. Grousers represent endless -like spring or -section-like spring coiled across said wire ropes with a pitch comparable or equal to that of aforesaid drive sprocket.

Hingeless rubber-reinforced track for harvester / 2403165

Invention relates to transport machine building. Hingeless rubber-reinforced track for harvester contains metal reinforcing elements made integral with track wheel guides and set at certain distance from each other throughout the length. Steel-wire cord is made as cable and wraps reinforcing elements from outside. Steel-wire cord and reinforcing elements are cured together in rubber into single endless chain with treads and bearing surface. On the bearing surface under each tread throughout track length, longitudinal projections are made at the edges of which there are transversal grousers. The grousers have chamfer towards track side faces. The bearing surface between longitudinal projections in its cross-section is made convex away from reinforcing element along ellipse curve and forms ellipsoid cavity throughout track length in longitudinal direction of track chain.

Caterpillar of wheel-track propulsor / 2484999

Invention relates to automotive industry, particularly, to wheel-tracked machine propulsors. Proposed caterpillar comprises endless flexible chain with multiple shaped elements secured thereat to make grousers. Said endless flexible chain 1 features notable elongated flay-oval cross-section and is twisted in the form of screw with grouser composed of round washer 2 arranged at every half-wave of said screw. Said grouser has notable elongated flat-oval back-lined hole commensurable with caterpillar cross-section.

Running gear with reinforced-rubber friction-engagement caterpillar track / 2510349

Invention relates to automotive industry. Proposed running gear comprises drive and gear wheels with cylindrical treads and reinforced-rubber caterpillar track running there over, reinforcing elements being made integral with guides spaced apart over the length. Steel cable embraces reinforcing elements from outside, said elements vulcanised in rubber to make endless track with treads and support surface with grousers. Track reinforcing element is made of strip-like resilient material of spring steel with ends bent in one side while mid part being bent towards said bend ends. Cylindrical tread of drive wheel features larger width than said cylindrical tread by double clearance between inner side of aforesaid guide and cylindrical tread lateral surface.

Hingeless rubber-reinforced track / 2516944

Hingeless rubber-reinforced track contains reinforcing elements (1) performed conjointly with guides (2), steel-wire cord made as cable (3) and supporting surface (6) with grousers (7). The guides (2) are located at certain distance from each other longwise. Reinforcing element (1) is made of resilient material in the form of cramp with turned in one direction ends (8), with straight segment (9) between them and is made of bar spring steel by hot forming. Turned in one direction ends (8) of reinforcing element is not conjointly cured in rubber (4) in single endless belt.

FIELD: automotive industry.

SUBSTANCE: endless caterpillar track comprises endless flexible member supporting multiple flexible-material spaced apart elements, grousers. Said endless flexible member represents at least two wire ropes, spaced apart for axial size of sprocket-type caterpillar drive element. Grousers represent endless -like spring or -section-like spring coiled across said wire ropes with a pitch comparable or equal to that of aforesaid drive sprocket.

EFFECT: simplified design of tracked propulsor.

The invention relates to transport machinery, namely to endless tracks for wheeled / tracked vehicles.

Known for an endless track for a tracked vehicle, containing endless flexible body in the form of a tape, on the outer surface of which is mounted across many located at a distance from each other elongated profiled elements made of elastic reinforced elastomeric material and forming open ends of the loop to grip, which is made separately from the flexible body and represent a segment of elastic material, collected by the sine wave with alternating protrusions and depressions, which is attached to the flexible body in places depressions /see SU 1588 272, CL B62D 55/24, from 14.07.1987/.

Endless caterpillar prototype structurally complicated and insufficient technology for the manufacture and use of wheeled / tracked vehicles of the type claimed by the patent of Russian Federation №2328259, CL A61G 5/06, from 02.04.2007.

The aim of the invention is to simplify the design and technology of endless tracks planned to be used for wheeled / tracked vehicles, including wheelchairs for disabled people with the drive.

Figure 1 presents a simplified cross-section for wheel-Gus the ranks vehicles, figure 2 - view And 1 with 90°rotation.

Endless track for wheeled / tracked vehicles, containing endless flexible body on which is mounted a lot situated at a distance from each other core elements of elastic material - lug, characterized in that the endless flexible body in the form of at least two non-contiguous along the entire length (spaced from each other in the axial size of the resulting caterpillar working body type sprocket (not shown) of the cables 2 and the lug 1 is made in the form of an infinite(solid line in figure 1) or(dashed line in figure 1) is shaped in the cross section of the spring is wound across the ropes with step 2, combined or equal to the step leading caterpillar working body type stars. In this case, at least the outer (peripheral) portion of the lug rubber or covered with a resilient elastomeric material.

We offer an endless track for wheeled / tracked vehicles, put on at least two rim having sprockets (gears) external gearing and connected gear-roller drive (Fig. not shown), is necessary and sufficient minimized device bus-caterpillars (lug 1), Yedinaya above the rim. When enabled, the drive torque is transmitted, for example, the gear-wheel, which causes the rotation of the wheels, and hence the bus-the caterpillar (lugs 1) around the rim.

Perpendicular to lines 2 parts of endless spring (i.e. located on the inner diameter) are fingers gearing for stars rotating between the 2 cables that serve the stars "guides". Thus δ (see figure 2) - structural size (generatrix) leading caterpillar working body type stars.

The outer peripheral portion of the lug 1 rubberized or coated with a resilient elastomeric material and, by virtue of design features (see the angular offset α of the links of the springs on one cable 2 in relation to the other rope 2), forms a herringbone pattern with respect to cable "guide". The latter creates more tractive effect of coupling flanges vehicles that have offered endless caterpillars.

Thus, according to the applicant, the invention is new, involves an inventive step and is industrially applicable.

1. Endless track for wheeled / tracked vehicles, containing endless flexible body on which is mounted a lot situated at a distance from each other core elements of elastic material - lug, different t is m, that endless flexible body in the form of at least two non-contiguous along the entire length apart from each other in the axial size of the resulting caterpillar working body type stars cables and lugs made in the form of endlessor-shaped in cross-section of a spring, coiled cables across increments commensurate or equal to the step leading caterpillar working body type stars.

2. Endless track for wheeled / tracked vehicles according to claim 1, characterized in that at least the outer peripheral portion of the lug rubber or covered with a resilient elastomeric material.
