A rack-and-pinion steering system and a method for producing the same including a pinion, a toothed rack, and a bearing point for the toothed rack, wherein the toothed rack includes a toothed first part and a non-toothed second part, wherein at least the first part and the pinion form a steering gear, and the steering gear is enclosed by a steering gear housing, and wherein the bearing point is enclosed by a bearing housing ensuring permanent lubrication. The second part of the toothed rack is exposed in at least one section between the steering gear housing and the bearing housing.

Divided steering gear housing having an exposed tooth rack

A steering rack housing (&#x2033;) for a power steering system that surrounds a steering rack in a tubular manner and includes a hydraulic region (), a mechanical region (), and as an inner supporting bearing (), wherein the supporting bearing is held in the steering rack housing (&#x2033;) by at least two cross-sectional contractions () of the housing.

Method for attaching a supporting bearing in a steering rack housing for a power steering system

In an electric power-steering gear, in particular for motor vehicles, having a steering shaft (,) which is actuated by a steering wheel and which forms an input for a step-down gear in the form of a harmonic drive (,) and which makes available an output, in the form of a steering element (,), to a conventional steering gear, sensors which output a signal for the steering torque which is applied being arranged on the steering shaft (,) in a known fashion, and said sensors leading, via a corresponding amplifier circuit, to an electric motor (,) which is arranged coaxially with respect to the steering shaft (,) and the steering element (,), the stator of the electric motor (,) is arranged fixed in terms of rotation in the externally toothed flexible rotor (,) and the elliptical driver (,) of the harmonic gear (,) acting, as a result of the elastically deformable, externally toothed flexible rotor (,), with migrating engagement on the internally toothed annular stator (,), which is fixed in position, and the flexible rotor (,) exerting a an auxiliary force on the steering element (,).
