Patent abstract
A variable steering rack system in one embodiment includes a pair of stop rings and a stopper moveable between the rings. The stopper may be rotatable in one embodiment during translational movement between the rings by a motor. Preferably, the stopper may stop due to a frictional engagement between the stopper and the stop rings. Noise may be reduced, and because the motor may rotate at a high speed, motor performance may not be degraded under low temperature circumstances.
