ABSTRACT:
A lower bearing assembly for supporting a steering shaft within a tubular jacket of an automotive steering column. The steering shaft is of double-D configuration having two diametrically opposite, arcuate side walls and two diametrically opposite parallel flats. A cup is fitted within the jacket having a hole in the bottom wall through which the steering shaft extends. A bearing within the cup supports the steering shaft for rotation. A wedge is sleeved on the steering shaft and has a tapered nose wedged between the bearing and the steering shaft. The wedge has an inner double-D configuration matching that of the steering shaft. A compression coil spring encircles the wedge and bears on a flange on the wedge to hold the nose of the wedge wedged tightly between the bearing and the steering shaft. A retaining ring is sleeved on the steering shaft and holds the spring under compression. The inner edge of the retaining ring has the same double-D configuration as the steering shaft.
