Embodiment Construction

[0071] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0072] figure 1 A side cross-sectional view schematically showing an exemplary embodiment of the rack steering device 1 according to the present invention. The rack steering device 1 includes a driving pinion 3 rotatably installed in the steering device housing 2, a rack 4 movably installed in the steering device housing 2, and the rack 4 is preloaded. Live the thrust block 5 of the driving pinion 3. The rotatable installation of the driving pinion 3 and the axial movement of the rack 4 are installed on figure 1 Not shown in detail. Similarly, the steering device housing 2 is figure 1 It is ...

Abstract

Described is a toothed-rack steering gear having a drive pinion (3) which is rotatably mounted in a steering housing (2) and which engages into a toothed rack (4) which is axially movably mounted in the steering housing (2), having a thrust piece (5) which preloads the toothed rack (4) against the drive pinion (3), and having at least one further machine element (15) which is operatively connected to the toothed rack (4) and which is mounted so as to be radially immovable with respect to the toothed rack (4), wherein the preload force exerted on the toothed rack (4) by the thrust piece (5) causes bending of the toothed rack (4).

Description

Technical field [0001] The invention relates to a rack steering device, in particular to a rack steering device suitable for a motor vehicle servo steering system. The invention also relates to a servo steering system. Background technique [0002] Many different designs of rack steering devices are known. For example, DE 101 62 470 A1 discloses a steering device applied to a motor vehicle. In the steering device, a thrust block used to apply pressure to the rack to press the rack and the driving pinion can be The way of longitudinal movement is guided in the connecting section of the steering device housing. Here, a preloaded force acts on the thrust block, and the direction of action of the preloaded force acting on the thrust block forms an angle with the direction of movement of the thrust block. The purpose of this design is to prevent the rattling noise caused by the intermittent contact of the thrust block. When the rack is moving, due to the action of the friction betw...
