A steering gear having a gearwheel (), a pinion shaft () which meshes with the former and is mounted such that it can be pivoted about a pivot axis which lies transversely with respect to the longitudinal axis () of the pinion shaft (), wherein the pinion shaft () is loaded against the gearwheel () by means of a spring element which is integrated into a locating bearing () for the pinion shaft (), which locating bearing () forms the pivot axis (), and wherein the pinion shaft () is mounted in a floating bearing () such that is spaced apart axially from the pivot axis, which floating bearing () ensures mobility of the pinion shaft () which makes pivoting of the pinion shaft () about the pivot axis possible, wherein the floating bearing () comprises an outer part and an inner part which is arranged movably in a radial direction with respect to the outer part, is characterized by a stop element () which limits the radial mobility of the inner part and can be positioned differently with regard to a stop surface which is provided for contact with the inner part.

Steering gear

A method and a system for producing a plastic housing are presented. In a first step, a base body and at least one closure element are produced, and in a second step an elastomer layer is applied by way of at least one gate point using a gating process, the layer joining the base body and the at least one closure element to each other.

Method for producing a steering gear housing

A housing for a steering gear and a plastic housing, wherein the plastic housing comprises a base body made of a plastic material, and elastomer layer and at least one closure element.

Housing for a steering gear

A fixed bearing for a steering gear having a rotary bearing which comprises an inner bearing shell which is provided for receiving a pinion shaft of the steering gear, and an outer bearing shell which is accommodated in a bearing bushing, and having a pivoting ring which has an outer ring and an inner ring which are pivotably connected via one or more torsion webs, wherein the outer ring is provided for supporting the fixed bearing in a housing of the steering gear, wherein the inner ring of the pivoting ring is mounted and axially secured on the outside of the bearing bushing.

A floating bearing for a steering gear, having an inner ring for receiving a pinion shaft of the steering gear and having an outer ring which surrounds the inner ring and which serves for the mounting of the floating bearing in a housing of the steering gear, wherein the outer ring and the inner ring form an annular gap between them and wherein the outer ring and the inner ring are connected to one another by means of at least one flexible connecting part such that said outer ring and inner ring are movable relative to one another in at least one radial direction, is characterized in that the outer ring and/or the inner ring form, within the connecting part, at least one projection which projects into the annular gap such that the spacing between the outer ring and inner ring is smaller in the region of the projection than in the remaining section of the annular gap.

Floating bearing for a steering gear

A steering gear having a gearwheel, having a pinion which meshes with said gearwheel and having a pinion shaft which comprises the pinion and winch is mounted so as to be pivotable about a pivot axis perpendicular to the longitudinal axis of the pinion shaft wherein the radial spacing between the pivot axis and the location of toothed engagement between the gearwheel and pinion is smaller than the core radius of the pinion.

A helical gear mechanism for a steering system in a motor vehicle comprises a helical pinion which engages with a helical gear and a bearing bushing which accommodates a bearing of the helical pinion. An inner ring of the bearing bushing is connected to an outer ring via a pivot bearing so that a pivoting motion of the helical pinion relative to the helical gear is possible. A pressure piece is disposed between the inner ring and the outer ring of the bearing bushing. The pressure piece is movable in a spring-loaded manner in a section of an annular gap between the inner ring and the outer ring. The inner ring and/or the outer ring are designed in the section so that the annular gap between the inner ring and the outer ring is tapered in the direction in which the pressure piece can be moved in a spring-loaded manner.

Helical gear mechanism for a steering system of a motor vehicle

A steering gear comprises a shaft bearing configuration which comprises a mounting which is installed in a housing section of the steering gear and has openings that enable a pivoting movement by an annular section of the mounting which is assembled with a first rolling bearing, and the mounting comprises a disk-shaped section, which is provided with the openings and relative to which the annular section can be pivoted, wherein the annular section is either assembled with the outer ring of the first rolling bearing and the disk-shaped section is attached to the housing section, or the annular section is assembled with the inner ring of the first rolling bearing and the disk-shaped section is attached to the shaft.

Steering gear having a fixed bearing and a floating bearing for a screw pinion

An electric power-assisted steering system of a motor vehicle comprises a helical pinion which engages into a helical gear. A reloading device comprises a reloaded pressure piece which presses the helical pinion into the toothing of the helical gear. The requirements of assembly are reduced and the elastically urging of the helical pinion or the worm need not be adjusted during assembly since the necessary elastically urging is automatically adjusted such that friction in the gearing is minimized, improved efficiency is achieved and the spring force can be held as constant as possible throughout the service life and unwanted noise development in the gearing can be largely reduced.

Helical gearing for a steering system of a motor vehicle

A steer-by-wire steering system has a steering wheel actuator and a braking device that acts on the steering column. The braking device is activated when the vehicle steering wheel is to be blocked or at least sharply braked, such as when the steering stop is reached or a wheel goes over the edge of a curb. The braking device functions like a switchable freewheel.

Clutch for steer-by-wire steering system

A steer-by-wire steering system is proposed, having a steering wheel actuator and a braking device that acts on the steering column (). The braking device is activated when the vehicle steering wheel is to be blocked or at least sharply braked, such as when the steering stop is reached or a wheel goes over the edge of a curb. The braking device functions like a switchable freewheel.
