摘要： A steering system of automobiles for absorbing impact force, which comprises a steering tube, connected to a steering handle, having a plurality of fixing openings for fixing balls therein; a steering shaft partially inserted into the steering tube and having a plurality of multi-stepped guide grooves for guiding the balls; and the balls positioned in the fixing openings of the steering tube. The guide grooves are adjacent to the fixing openings at one end and extended longitudinally for a predetermined distance, and the balls travel from the fixing openings into the multi-stepped guide grooves between the steering tube and the steering shaft, generating frictional force and absorbing impact force. Hence, the impact force is absorbed by the multi-stepped portions of the guide grooves and gradually transmitted to the driver from the beginning to the end of a collision to ensure the driver with enough time to react to the collision, thereby minimizing injury to the driver.

摘要： Disclosed is a reducer of an electric power steering apparatus. The disclosed reducer includes: a worm shaft bearing coupled with an end of the worm shaft's motor shaft coupling portion in such a manner that a ball coupled between an inner wheel and an outer wheel supports rotation of the worm shaft; and a first damper and a second damper which are tightly fitted in one side and the other side of the worm shaft bearing, respectively, while being insertedly-coupled with the worm shaft, so as to support the worm shaft and absorb a rattle noise transferred via the worm shaft, wherein each of the first damper and the second damper is provided with supporting plates at both sides thereof, and between the supporting plates, a damper made of an elastic material is coupled and formed. The reducer of the electric power steering apparatus reduces a rattle noise which occurs by an increase in backlash caused by abrasion of the worm and the worm wheel, or occurs by an impact transferred from a road via a wheel and the steering shaft, thereby providing a pleasant driving condition to the driver.
