An air suspension system for a load bearing vehicle which includes a pair of air springs fluidly connected to a pair of auxiliary air reservoirs and to a main air reservoir. The system includes control valves which permit the air in the air springs to be exhausted therefrom to lower the vehicle frame without exhausting the air from the auxiliary air reservoirs.

Air suspense system for a vehicle

Air suspension system for a vehicle

An axle suspension system for a load-bearing vehicle is described which comprises first and second mounting brackets secured to the longitudinally extending frame members of the vehicle. First and second lower control arms are pivotally secured at their forward ends to the first and second mounting brackets and extend rearwardly therefrom. First and second axle supports are positioned rearwardly of the first and second mounting brackets and have the rearward ends of the first and second lower control arms pivotally secured thereto. An axle and wheel assembly is secured to the first and second axle supports. First and second air springs are operatively secured to the first and second axle supports. A stabilizer bar assembly is provided and combines the functions of a stabilizer bar and upper control arms. The stabilizer bar assembly includes a central base portion which is pivotally secured to the first and second axle supports and which has forwardly extending end portions provided at the opposite ends thereof. The forward ends of the end portions of the stabilizer bar assembly are pivotally connected to the first and second mounting brackets to perform the function of upper control arms. In a second embodiment, the stabilizer bar assembly combines the function of a stabilizer bar and lower control arms.

A cab suspension for a vehicle having a chassis supporting a cab with the cab being supported on the chassis at a forward location and at a rearward location so as to permit vertical movement of the rearward end of the cab relative to the chassis. Conventional forward support structures connect the forward end of the cab to the chassis. A rearward support structure or suspension unit connects the cab to the chassis at the rearward end of the cab to provide relative vertical movement therebetween. The structure comprises an elongated metal tube having its longitudinal axis disposed transversely with respect to the longitudinal axis of the chassis with the tube being secured to the chassis. The tube has an elongated, resilient rubber or elastomeric cartridge positioned therein which has an elongated torsion bar extending therethrough which is in engagement therewith so that the cartridge restricts rotational movement of the torsion bar with respect to the tube. Lever arms are fixedly secured to the ends of the torsion bar and extend forwardly therefrom for adjustable connection to a bracket which is secured to the lower rearward end of the vehicle cab.
