Axle controller for industrial vehicles

摘要

An industrial vehicle having an axle (11) pivotally supported on a frame (1a). The vehicle includes a damper (12) for connecting the axle to the frame. The damper allows pivotal motion of the axle when the damper expands or contracts. A conduit is connected to the damper for supplying oil to the damper and for discharging the oil from the damper. A control valve (13) is connected to the conduit to selectively open and close the conduit. A controller (C) controls the control valve. Oil is permitted to enter and exit when the conduit is opened by the control valve. The supply of the oil from the conduit is closed by the control valve. A pressure adjuster is connected to the conduit for accommodating increases in the oil pressure in the conduit when the conduit is opened and for replenishing the conduit with oil due to losses from leakage.
