Steering system for a vehicle with a power steering device

摘要

A hydraulic power-assisted steering device with a pump (10) and a synchronizing cylinder (20) uses preset hand-operated torque on a steering gear mechanism to trigger variable-amount torque. A hydraulic reaction device has bypass lines (22,26), a bridge circuit (24), parallel lines (28,30), a transverse line (32), stop devices (34,36,38,40,44), an actuator (42), an inversion circuit and a valve.
