Zahnstangen-Lenksystem.

摘要

A fluid power assisted rack and pinion steering system includes a steering gear assembly (10) having a valve core (40), a valve sleeve (42), and an axially extending torsion bar (60). The input shaft (38) of the steering gear is formed as the valve core, and one end (110) of the torsion bar is pinned to the input shaft before the valve is balanced. A pinion (18) is connected to and rotates with the valve sleeve, and the other end (130, 132, 134) of the torsion bar is rotationally fixed to the pinion. The pinion has an axially extending tapered bore (118) in which is received a matching tapered portion (130) of the torsion bar. The tapered portion of the torsion bar engages the tapered portion of the bore in the pinion in a rotationally fixed locking engagement. Upon assembly of the steering gear, if the valve is not properly balanced, the tapered connection is easily loosened to adjust the relative angular orientation of the pinion to the torsion bar, and then retightened to again fix the torsion bar to the pinion.
