Power steering for a vehicle has section of steering column that forms rotor of electrical DC or linear motor drive that applies torque assisting rotary motion to steering column

摘要

The vehicle steering system has a steering column (1) between a steering wheel (2) and a steering box (3) to transfer a rotary movement of the steering wheel directly to the steering box. A section of the steering column forms the rotor of an electrical drive that applies a torque assisting rotary motion to the steering column. The drive can be a DC or linear motor.
