ABSTRACT:
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.
