ABSTRACT:
An air-adjustable shock absorber is pivotally connected at its ends to first arms of a front end of a back crank arm system, which are pivotally mounted to the vehicle chassis at the front and back of the same between the upper and lower runs of the endless track of the vehicle. The second arms of the front and back crank arm systems are connected to the front and back portion of the slides which engage the upper surface of the ground-engaging run of the endless track. The air pressure within the shock absorber unit biases the two crank systems in a direction so as to move the slides downwardly from the vehicle chassis. An air circuit system enables the driver to control the air pressure depending on the load carried by the vehicle. The crank systems are such that a greater proportion of the load is carried by the back of the suspension.
