ABSTRACT:
An improved vibration dampening and shock absorber suspension device for the cab of a truck vehicle is set forth having a base member adapted for mounting to the truck frame and an impact plate adapted for attachment to the truck cab where the impact plate has a lateral dimension which is less than the lateral distance between the side beams of the truck frame. Interposed between the base member and the impact plate is a pair of air springs which are maintained at a constant height by a height control valve. A pair of hydraulic shock absorbers are pivotally connected to both the impact plate and base member where the central axis of the shock absorbers form the opposite sides of a trapezoid.
