Embodiment Construction

[0057] Such as figure 1 Shown is an exemplary embodiment of a rack and pinion steering 1 according to the invention comprising a steering housing 2 , wherein a pinion 3 is mounted rotatably about an axis of rotation 4 and a rack 5 is mounted axially displaceable. The direction of the axial displacement of the rack 5 is the same as figure 1 The drawing plane is vertical.

[0058] Such as figure 1 As shown, the pinion 3 has a substantially cylindrical configuration with a toothing 6 meshing with a toothing 7 of the rack 5 at its outer periphery.

[0059] The pinion 3 has upper and lower shaft overhangs 8 and 9 at its axial ends, respectively. The upper shaft extension 8 is non-rotatably connected to the steering shaft ( figure 1 not shown in ), which in turn is connected to a steering wheel (also not shown) through which an operator, such as a driver of a motor vehicle, makes steering input. Between the steering wheel and the pinion 3 is advantageously provided a servo unit...

Abstract

The invention provides a rack type steering device (1), which comprises a steering device housing (2), a pinion gear (3) which is non-rotatably connected to the steering shaft and rotatably installed in the steering device housing (2), and a rotatable The gear rack (5) installed in the steering gear housing (2) is axially displaced, and the teeth of the pinion (3) mesh with the teeth of the rack (5). The pinion (3) can be pre-set The load bears against the rack (5), and the rack (5) is mounted in the steering housing (2) through linear rolling bearings.

Description

technical field [0001] The invention relates to a rack-type steering device, in particular to a rack-type steering device for motor vehicles, the steering device includes a steering device housing, is non-rotatably connected with a steering shaft and is rotatably mounted on the steering device housing The pinion gear inside, and the rack gear installed axially displaceable in the housing of the steering gear, the teeth of the pinion mesh with the teeth of the rack. [0002] The rack-and-pinion steering is used in a known manner to transmit the rotational movement of a steering wheel, which is connected, for example, non-rotatably via a steering shaft to a pinion of the rack-and-pinion steering, a rack of the rack-and-pinion steering, the rack This in turn is axially displaced and rotated by one or more wheels via a steering linkage connected to one or more wheel carriers. Background technique [0003] Especially in power steering systems with electric and / or hydraulic drive...
