摘要： A suspension system for a tracked vehicle including a unitary suspension frame with track wheels mounted thereon for engagement with the lower run of the drive track. Idler means mounted on the rear end of the suspension frame support the rear end of the drive track. Spring means are provided to support the vehicle body on the suspension frame. The spring means are connected such that a predetermined amount of longitudinal relative movement is permitted between the suspension frame and the body. A rearwardly and downwardly sloping control arm is pivotally connected between the body and the front end of the suspension frame so that the forwardly located track wheels are forced downwardly by the control arm when the suspension frame moves forwardly with respect to the body.
