Abstract
A spiral-toothed gear wheel for a rack and pinion steering. The spiral-toothed gear wheel includes a pinion, which meshes on the power take-off side with a toothed rack, and a spiral-toothed gear, which is arranged on the pinion on the drive side in such a way that they rotate in unison, and on which a torque caused by a steering power or/and steering assist power acts. The spiral-toothed gear is designed as a built-up gear and includes a gear rim, which is arranged, relative to the axial direction of the gear or of the pinion thereof, between two flanges. The gear rim is pushed over a hub formed at one of the flanges and is fitted together with the flanges in a positive-locking manner. One of the flanges, namely, the flange having the hub for the gear rim, is made in one piece with the pinion.
