Abstract
The invention concerns a suspension device for a tracked vehicle, comprising a track assembly (10) at the side of a centre beam (14), comprising a track support beam (20), two wheels (21, 22), several support wheels (23) and an endless track (11) that runs in a plane of rotation (A, A), a first suspension mounting with which the support wheels (23) are suspended at the track support beam (20) in a manner that allows pivoting, a second suspension mounting comprising a combination of a first spring strut (25A) and a first pendulum arm (26A) and a second spring strut (25B) and a second pendulum arm (26B) with which combinations the centre beam (14) of the chassis is spring-damped at a forward and rear end of the track support beam (20). According to the invention, a first pendulum arm (26A) is located in front of the second pendulum (26B), each pendulum arm (26A, 26B) is fixed at its first end in a manner that allows pivoting at a first joint (27, 27) the centre beam (14) of the chassis and at its second end at a second joint (28, 28) at the track support beam (20), each spring strut (25A, 25B) is fixed at one of its ends (30, 30) in a jointed manner at the centre beam (14) of the cha…
