Power steering apparatus with steering wheel angle correction device

摘要

An industrial vehicle has rear wheels (119) steered by a hydraulic power steering apparatus in accordance with a rotation of a steering wheel (102). The vehicle includes an electromagnetic switching valve (122) that corrects discrepancies between an angular position of the steering wheel (102) and a wheel angle of the rear wheels (119) by racing the steering wheel (102) when the discrepancy exceeds a predetermined value. The vehicle further includes a central processing unit (141) that suppresses the operation of the switching valve (122) under certain conditions.
