Steering gear and system for automotive vehicle.

摘要

A steering gear for an automotive vehicle includes a linear electric motor (37) having a plunger (38) linked to an axle set of roadwheels with a vehicle and a controller (56) for operating the linear motor. The controller (56) may include sensors for torque applied to a steering shaft attached to a steering handwheel operated for the driver and for also sensing vehicle speed. A controller (56) and steering gear (10) according to the present invention may be used with four-wheel steering systems in which no mechanical link is provided between the front steering gear and the rear steering gear.
