ABSTRACT:
An apparatus for controlling the friction between the leaf springs of a laminated leaf spring assembly comprises a clamping mechanism, a hydraulic cylinder mechanism, a hydraulic control mechanism and a detecting mechanism. The clamping mechanism includes a guide member and a press member. The guide member and the press member hold and clamp the laminated leaf spring assembly. The hydraulic cylinder mechanism has a cylinder and a piston movable in the cylinder and presses the press member to urge the laminated leaf spring assembly against the guide member. The hydraulic control mechanism has a pressure reducing value for controlling the pressure of a liquid supplied to the cylinder of the hydraulic cylinder mechanism. The detecting mechanism detects the values of the predetermined factors of a body supported by the laminated leaf spring assembly and supplies signals representative of the values to the pressure reducing valve. According to the signals from the detecting mechanism, the pressure reducing valve controls the pressure of the liquid supplied to the cylinder of the hydraulic cylinder mechanism.
