FIELD: transportation.

SUBSTANCE: caterpillar includes an outer surface for engaging with the ground and an inner surface for engaging the vehicle's driving wheel. On the outer side, there are a lot of ledge-grousers for gripping with the ground. Ledge-grousers make a single structure with the body of the caterpillar and are located along the width of the strip in the form of alternating first row and second row. The ledge-grousers of the first row are generally perpendicular to the outer surface of the belt. The ledge-grousers of the second row are located at an angle relative to the normal to the outer surface of the belt.

SUBSTANCE: according to first design version, width of each outer connecting clamp is within 12 and 15% of total width of track. Through hole for fastening detachable widener is made in outer part of connecting clamp relative to central axis of track. Cutout is made from side of support surface to form L-shaped profile in cross section of outer connecting clamp for use as upper and side support surfaces when mounting detachable widener. Novelty in track, according to second design version, is that width of each outer connecting clamp is set within 12 and 15% of total width of track, minus widener projection value. Through hole is made in outer part of outer connecting clamp relative to central axis of track. Cutout is made from side of support surface to form L-shaped profile in cross section of outer connecting clamp. Detachable widener is installed in said cutout made in form of plate with thickness decreasing with change into outer side from central axis of track provided with eye with threaded hole in which bolt is installed, coupling widener with outer connecting clamp through said through hole in clamp. Upper and side parts of widener rest, respectively, on upper and side parts of L-shaped profile of cutout.

SUBSTANCE: proposed track chain has links connected by pins and provided with eyes with holes to receive connecting pins. Large and small grousers are made on outer side of links. Said grousers are essentially straight-line ribs arranged parallel to holes for connecting pins. Links are provided additionally with two hydraulic cylinders of small and large cross-section, with pistons of small and large areas, springs of pistons of small and large cross-section, separating valve and pipeline. Both cylinders are interconnected by pipeline accommodating separating valve. Large grouser is rigidly secured on small-area piston, and small grouser, on large-area piston. Spring of small cross-section cylinder loads small-area piston from top, and spring of large cross-section cylinder loads large-area piston from bottom. Grousers are made so that large grouser-to-ground contact area considerably exceeds similar area of small grouser, and separating valve opens when liquid pressure from side of small cross-section hydraulic cylinder reaches definite value.
