Abstract:
An auxiliary axle suspension system for a motor vehicle is disclosed wherein a pair of hydraulically operated actuators position and force the auxiliary axle to help support the vehicle. And gas springs are provided that allow the actuators to extend and retract over a wide range of hydraulic operating pressure and thereby allow the auxiliary axle to adjust to a wide range of road grade differences between the auxiliary axle wheels and the wheels of the axles that normally support the vehicle without incurring significant gas and hydraulic pressure fluctuation and while isolating shock forces on the auxiliary axle wheels from the vehicle.
