Abstract

The invention relates to a rack-and-pinion steering gear with a steering housing (1), which is tubular and has a housing axis (8), wherein in the steering housing (1) a rack (3) is mounted in bearings (10) displaceably towards a longitudinal axis (4), and with a steering pinion (5), which is mounted in a pinion housing (2) rotatably about an axis (6) and has a pinion gearing, which engages with a gearing of the rack (3), in which at least one bearing (10) is formed as an eccentric sliding bearing, which can rotate relative to the steering housing (1), so that the rack (3) can be pressed towards the steering pinion (5).

Description

technical field [0001] The invention relates to a steering gear with a steering housing which is formed in a tubular manner and which has a housing axis, wherein in the steering housing a toothed rack mounted in the bearing movably in the longitudinal direction; a steering gear drive gear rotatably mounted in the drive gear housing around an axis, and having a toothed portion with the rack Meshing drive gear teeth. Background technique [0002] At present, the rack and rack steering mechanism is used as a steering transmission mechanism and occupies an absolutely large proportion in automobile manufacturing. It is suitable for hydraulic servo-assisted or electric servo-assisted steering and non-servo-assisted steering. Typically, the steering gear has a rack with a rack mounted therein displaceably in the longitudinal direction. A steering drive pinion is rotatably disposed within the pinion housing and meshes with a mating tooth portion of the rack. The driving gear of ...
