  • Rack and pinion steering mechanism
    Patent number: 4815329
    Abstract: A conventional rack and pinion vehicle steering mechanism of the kind having a spring biased pressure member for compensating for tooth wear has a non-rotative friction spring biased against a coacting frictional torque resistance that prevents the pinion from transmitting oscillatory to-and-fro vibratory movement of the rack to the steering spindle through the pinion. The result is the avoidance of steering wheel shimmy otherwise felt by the vehicle operator.
