ABSTRACT:
Each of several single-acting, load distributing, hydraulic cylinders interposed between respective axles and the frame of a truck is provided with a control device having a cylinder element and a plunger element connected to the plunger and cylinder members of the load distributing cylinder for joint movement. The control cylinders are permanently connected to a control line carrying hydraulic fluid, and the several load-distributing cylinders communicate through respective valves with a pressure line normally sealed from the control line. Each valve disconnects the associated, load-distributing cylinder from the pressure line connecting it to other cylinders when the pressure differential between the associated cylinder and the control line exceeds a predetermined value.
