A steering apparatus and method for a vehicle. Steering controllers are connected via an internal communications network. Each of the steering controllers monitors the operating state of another steering controller using the internal communications network, so that, if one of the steering controllers currently controlling the steering motor operates abnormally, the steering motor is controlled by at least one steering controller of the remaining steering controllers.

Steering apparatus and method for vehicle

A rack-assist type electric power steering apparatus, in which when a ball nut slides a rack bar while rotating, a vibration and a noise in the axis direction and the radial direction, generated from the rack bar and a rack housing, are absorbed. This facilitates the operation of the ball nut and the rack bar, and reduces the vibration and the noise, thereby resulting in an effect for providing a comfortable steering feeling to a driver.

Rack assist type electric power steering apparatus

An electric power steering apparatus includes: a motor for providing assistant steering power; a following pulley connected with the motor through a belt to receive a driving force; a gear housing surrounding the following pulley; a motor housing rotatably assembled with the gear housing; and a tension adjusting mechanism for adjusting a rotation angle of the motor housing so as to adjust a tension of the belt. Therefore, the relative rotation angle of the motor housing respective to the gear housing can be adjusted so that the tension of the belt can be easily controlled and the generation of vibration and noise of the belt can be prevented.

Electric power steering apparatus equipped with tension adjusting mechanism

The present invention relates to a rack assist type electric power steering system, and in particular to an improved rack assist type electric power steering system which is capable of decreasing a processing section of a ball screw by improving an installation position and structure of a ball screw, protecting a connector and sensor of a motor assembly from a heat source and preventing any interference of parts due to a drooping of a rack bar. The system according to the present invention includes a rack bar, an input shaft, a rack housing, a torque sensor which surrounds an upper surrounding portion of the input shaft and is fixed to an upper portion of the rack housing; a second rack housing which surrounds the straight line section of the rack bar and contacts by a bush inserted into an inner diameter portion of the same, and a motor assembly.

Rack assist type electric power steering system

A vehicular electric power steering apparatus with an enhanced supporting structure for improving the bending strength of a rack bar includes a motor having a rotor, a stator and a motor shaft inside the same; a housing installed such that it can communicate with the motor; a rack bar installed inside of the motor and housing and having a ball screw installed at the outer circumferential surface of one end and a rack gear formed at the outer circumferential surface of the other end; a ball nut installed at the outside of the ball screw for supporting the rack bar at a first point and moving the same in the axial direction; and a rack guide installed at the inside of the housing for supporting the rack bar at a second point and guiding axial movement by enclosing the rear surface of the rack gear, where the rack bar is supported at a third point by a supporting bush disposed at the inside of the front end of the housing adjacent to the rack guide.

Electric power steering apparatus for a vehicle

An electronic power steering apparatus for a vehicle which. is capable of (a) improving the structures of a stop ring and a groove for thereby preventing a certain operational gap which is formed when installing the system and (b) providing a torque limiting function when an over load occurs in the motor. A circular groove in a motor shaft is formed with a beveled surface disposed in contact with a similarly beveled or inclined surface on a stop ring inserted into the groove. The stop ring is formed to be expandable in the outer direction and upon expansion in the groove moves in an axial direction due to the engaged beveled surfaces.
