ABSTRACT:
Disclosed is a tilt cab suspension system comprising integral shock absorber and air spring assemblies located between the truck frame and the cab. The shock absorber assembly comprises a hydraulic circuit which provides for circulation of hydraulic fluid during an upstroke and/or downstroke of a piston within a cylinder. A selectively adjustable control valve is located in the hydraulic circuit and may be regulated by the vehicle operator to control the stiffness of the shock absorber sub-assembly and, consequently, the hardness of the ride.
