Abstract
An adjustable rear suspension system for a tracked vehicle comprises a slide frame for guiding a portion of the endless track, the slide frame having a pair of substantially parallel slide rails, the slide rails defining a longitudinal direction. The rear suspension system further comprises at least one spring-like member for urging the slide frame away from the chassis. A front suspension arm assembly has an upper end pivotally connected to the chassis and a lower end pivotally connected to the slide frame. A rear suspension arm assembly has ail upper arm pivotally connected to the chassis and a lower end connected to at least one block capable of limited displacement in the longitudinal direction between a front stopper and a rear stopper. The rear suspension system further includes a rocker arm having an upper end connected to at least one block and a lower end pivotally connected to the slide frame. This rear suspension system compensates for rearward weight transfer caused by rapid forward acceleration of the tracked vehicle.
