A power steering pumping apparatus for a vehicle may include a driving motor, a power steering pump connected to a first side of a shaft of the driving motor, a compressor connected to a second side of the shaft of the driving motor, and a clutch disposed between the driving motor and the compressor and intermitting power between the driving motor and the compressor.

Power steering pumping apparatus for vehicle

An electric actuator-integrated electric power steering system may include an integrated motor which provides rotational force, a hydraulic pump connected to one end of the integrated motor and supplied with the rotational force from the integrated motor to pump working fluid that is used to transmit steering force, and an electric actuator connected to the other end of the integrated motor via a power controlling means. The electric actuator may operate when the rotational force is transmitted to the electric actuator and whether the rotational force from the integrated motor is transmitted to or cut off from the electric actuator may depend on an operation of the power controlling means.

The present invention provides a variable steering gear ratio apparatus adapted to adjust the steering gear ratio based on the vehicle speed and steering angle, thereby facilitating steering manipulation by applying a small steering gear ratio when the vehicle comes to a parked state, the vehicle speed is low, or the steering angle is large. By applying a large steering gear ratio when the vehicle speed is high or the steering angle is small, the steering stability of the vehicle improves.
