Abstract

PURPOSE:To raise the vibration suppressing efficiency and safety during travel ing of a vehicle by a method in which an accumulator is connected through a mode-switching valve and a throttle to a hydraulic cylinder for operation by an outside pipe. CONSTITUTION:An accumulator 19 for suppressing vibration is set through a mode-switching valve 18 and a throttle 20 on the load holding side oil chamber 8a of a hydraulic cylinder. The valve 18 is designed to be freely switched to an interruption position (operation mode) or to a communication position (opera tion mode). In case of operation mode, the accumulator is connected through the throttle, whereas in traveling mode, the connection is made without the throttle. The expanding or contacting movement of the hydraulic cylinder during traveling period is absorbed by the accumulator to suppress vibration.
