 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.
 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
 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.

 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: transport. SUBSTANCE: 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.

The invention relates to the transport industry, in particular to the wheel-tracked propulsion 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, B62D 55/24, 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 and 2 presents a simplified screw half tracks for wheeled gusen knogo propulsion. The stated objective is achieved by the fact that the caterpillar wheel-track Assembly containing an endless flexible tape on which is mounted a lot situated at a distance from each other core elements of elastic material - lug, an endless flexible belt 1 with strongly elongated PlasmaWall section is twisted in the form of a circular washer 2 with comparable cross-section of the tape is greatly elongated plancoulaine edged hole. While the flexible tape can have on its centerline perforation under the device additional fixing lug on the ribbon. While the flexible tape Assembly with the lug may be gummed or coated with a resilient elastomeric material. Flexible tape 1 calculated length perforined centerline increments commensurate step recorded on the tape lug-washers 2, after which one end of the tape is twisted relative to the other end of the tape to be commensurate with the number of lugs, the number of helical half-cycle and combined in infinite tape, perform the function of caterpillars for krasnosulinskogo propulsion. Caterpillar wheel-track Assembly according to the proposed technical solution is simple structurally and technologically in manufacturing, has the necessary and sufficient bearing capacity, attenuated the impact of PR is pastia, increases the smoothness of the vehicle. Thus, according to the applicant, the invention is new, involves an inventive step and is industrially applicable. 1. Caterpillar wheel-track Assembly containing an endless flexible tape on which is mounted a lot situated at a distance from each other core elements of the elastic material of the lug, wherein the endless flexible strip with strongly elongated PlasmaWall section twisted like a screw, at each half-wave which has the lugs in the form of a circular washer having comparable with the cross section of the tape is greatly elongated plancoulaine edged hole. 2. Caterpillar according to claim 1, characterized in that the flexible strip may have at its centerline perforation under the device additional fixing lug on the tape. 3. Caterpillar according to claim 1 or 2, characterized in that the flexible strip Assembly with the lug may be gummed or coated with a resilient elastomeric material.
