ABSTRACT:
Disclosed herein is a vehicle including a frame, and a stabilizer apparatus including a pressure source, first and second fluid-actuated stabilizer assemblies connected respectively to the front and rear axles shiftably moveable on the frame, one of the first and second stabilizer assemblies normally being locked against extension and contraction in the absence of pressurization thereof by the pressure source, and the other of the first and second stabilizer assemblies normally being free to extend and contract in the absence of pressurization thereof by the pressure source, a hydraulic circuit connected between the pressure source and the first and second fluid activated stabilizer assemblies and including a flow controller operable between a first mode wherein the pressure source is disconnected from the first and second stabilizer assemblies, whereby the one of the stabilizer assemblies is locked against extension and retraction, thereby locking the axle connected thereto against shifting movement relative to the frame, and whereby the other of the stabilizer assemblies is free to extend and retract, thereby permitting shifting movement relative to the frame of the axle connected thereto, and a second mode wherein the pressure source is selectively connectible to the first and second stabilizer assemblies for selective pressurization thereof by the pressure source so as to selectively extend and retract the first and second stabilizer assemblies.
