SUSPENSION DEVICE FOR CRAWLER VEHICLES Russian patent published in 2021 - IPC B62D55/104 B62D55/116 

FIELD: crawler vehicles.

SUBSTANCE: invention relates to a suspension device for a crawler vehicle. The crawler vehicle contains crawler assembly (10) on the side of central beam (14) containing support beam (20) of a caterpillar, two wheels (21, 22), several support wheels (23) and crawler belt (11). The first mounting of a suspension, using which support wheels (23) are suspended on support beam (20) of the caterpillar, allows for turning the second mounting of the suspension containing a set of first spring rack (25A) and first pendulum arm (26A) and second spring rack (25B) and second pendulum arm (26B). First pendulum arm (26A) is located in front of second pendulum (26B). Each pendulum arm (26A, 26B) is fastened at its first end in such a way that it allows for turning on first hinge (27, 27) on central beam (14) of chassis and at its second end – on second hinge (28, 28) on support beam (20) of the caterpillar. Each spring rack (25A, 25B) is fastened at one of its ends (30, 30) in a hinged way on central beam (14) of chassis, and on its second end (31, 31), it is fastened in a hinged way on pendulum arm (26A, 26B). Pendulum arms (26A, 26B) turn in a plane-parallel way with surfaces of rotation (A, A) of caterpillar (11).

EFFECT: area of surface traction is increased.
