A steering apparatus for a vehicle according to the present disclosure includes: a controller configured to transmit steering control signals on the basis of a first input signal from a torque sensor configured to sense torque of a steering shaft and a second input signal from any one of a location sensor, a camera sensor, a distance sensor, a vehicle speed sensor, and a vehicle height sensor; a first steering power assist configured to generate steering force by rotating the steering shaft or supplement steering force of the steering shaft rotating forward or backward, using electric power in response to the steering control signal from the controller; and a second steering power assist configured to switch channels for working fluid, depending on forward or backward rotation of the steering shaft, and steer wheels by operating a tie rod or a knuckle using hydraulic pressure of the working fluid.

Steering apparatus for vehicle

A power transmission member for an electric power steering system, which connects a driving shaft and a driven shaft on the same axis to transmit power therebetween, includes: a first boss coupled to one of the driving shaft and the driven shaft and having a first receiving part that is formed in the central portion thereof and has a cylindrical shape; a second boss coupled to the other shaft and having a second receiving part that is formed in the central portion thereof and has a cylindrical shape; and an axial damper configured to elastically deform in the axial direction while opposite end portions thereof are inserted into the first and second receiving parts.

Power transmission member for electric power steering system

A rack-driven auxiliary power steering apparatus prevents a ball nut and a nut pulley from idling due to a slip thereof and increases durability when the drive belt is operated by driving of a motor, and minimizes vibrations and noise transferred through the rack bar, the ball nut, and the nut pulley when the rack bar is slid while the nut pulley and the ball nut are rotating, thereby providing a comfortable steering feeling to the driver.

Electric power steering apparatus of ball screw type

Rack-driven auxiliary power steering apparatus

A power steering apparatus includes: a torque sensor for detecting a steering torque applied to a steering wheel and outputting a torque signal corresponding to the steering torque; a speed sensor for detecting a speed of a vehicle and outputting a speed signal corresponding to the speed of the vehicle; a humidity sensor for outputting a humidity signal corresponding to a humidity of an interior of the power steering apparatus; and an electronic control unit for receiving the humidity signal from the humidity sensor, and for, when a measured humidity is an reference value or higher, generating a motor current signal for supplying an assistant steering force smaller than an assistant force set in response to the torque signal and the speed signal.

Power steering apparatus capable of sensing moisture

A rack driving-type power assisted steering apparatus having effects of preventing a lock screw from being loosened due to vibration in axial and radial directions generated by a rack bar, a ball nut, and a rack housing when the rack bar slides while the ball nut rotates, reducing vibration and noise of the ball nut and the rack bar transferred through a bearing, and providing a driver with steering comfortability.
