The disclosure relates to an apparatus for pressing a rack onto a pinion, with a pressure piece. The pressure piece being arranged within a housing and to be displaceable in an axial direction of a center longitudinal axis. A bearing element is fixed on the housing in the axial direction with respect to the center longitudinal axis. A prestressing element acts in the axial direction. The pressure piece is loaded by the prestressing element which is arranged between the pressure piece and the bearing element with a prestressing force in the axial direction with respect to the center longitudinal axis and directed away from the bearing element. An adjusting ring which is arranged between the bearing element and the pressure piece. At least two inclined faces of the adjusting ring and an adjusting section bear against one another. In order to be able to reduce the production outlay and/or realize a more compact overall design, a force application disk is arranged between the adjusting ring and the adjusting section.

A device for a steering system of a motor vehicle for pressing a toothed rack against a drive pinion is specified, the device having a housing and a thrust piece which is mounted displaceably in the housing and which has a circumferential wall which is in contact with the housing, the thrust piece having, on its circumferential wall, at least one depression which runs in a circumferential direction at least in certain portions and which delimits a hollow chamber arranged between thrust piece and housing.

A rack guide bearing for meshing a pinion and vehicle steering system rack, the guide bearing including a wall, a first portion is tubular and defines an axis and internal channel around the axis opening at the guide bearing first end, and opening onto a second portion of the wall opposite the first end, an internal channel section transverse to the axis and inserts the rack into the channel according to the rack axis parallel to the guide bearing axis, the guide bearing including an internal channel inner surface of the guide bearing wall's first portion and an inner surface of the guide bearing wall's second portion, the inner surfaces are in slipping contact with a slipping surface of the rack opposite to a toothing of the rack, when the rack is inserted inside the first portion of the wall's internal channel according to the axis of the rack.

Disclosed is a steering apparatus including: a mounting housing which is formed on one side of a rack housing and has first threads formed on an inner circumferential surface thereof; a yoke body which is provided inside the mounting housing and supports a rack bar located inside the rack housing; and a pressing member which is provided inside the mounting housing, has second threads formed on an outer circumferential surface thereof, and is coupled to the mounting housing in a state in which the second threads are coupled to the first threads and are separated from the yoke body.

A transmission system includes an input shaft, a transmission housing, and a planetary gear system rotatably coupled to the input shaft. The planetary gear system has a first and second gear ratio. The transmission system additionally includes an output shaft, a first electric machine, a second electric machine, and a shifting assembly. The shifting assembly includes a first stationary clutch element and a second stationary clutch element. The first electric machine is configured to apply rotational torque to the planetary gear system to synchronize rotational speed of the planetary gear system when moving between the first and second gear ratios, and the second electric machine is configured to provide rotational torque to the output shaft when the first electric machine applies rotational torque to the planetary gear system to synchronize rotational speed of the planetary gear system when moving between the first and second gear ratio.

A cylindrical part of a rack retainer accommodation part and an adjust screw are caulked such that a plastic deformation region by caulking straddles both a female screw part of the cylindrical part and a male screw part of the adjust screw, and the adjust screw is loosened to a point where a set load that is a force by which the rack retainer urges a rack bar falls within a predetermined range. After the set load adjusting step, the caulking step is not performed again, and fluctuations in the set load associated with the impact of caulking work after the set load adjusting step can be suppressed. Thus, it is possible to suppress fluctuations in the urging force of the rack retainer applied to the rack bar caused by caulking work which stops the rotation between the rack retainer accommodation part and the adjust screw.

The disclosure relates to an apparatus for pressing a toothed rack against a pinion, having a pressure piece. The pressure piece can be arranged so as to be displaceable inside a housing and in an axial direction of a centre longitudinal axis. A bearing element that can be fixed on the housing in an axial direction with respect to the centre longitudinal axis, having a prestressing element that acts in an axial direction. Action of the prestressing element arranged between the bearing element and the pressure piece subjected the pressure piece to a prestressing force in an axial direction with respect to the centre longitudinal axis and directed away from the bearing element. A sliding element is arranged on a side, facing away from the prestressing element, of the pressure piece for the purpose of bearing against the toothed rack. In order to reduce the production outlay and/or allow a more compact design, on the side bearing against the sliding element, the pressure piece has a contour for compensating tolerances. The contour interacts with the sliding element.

The disclosure relates to an apparatus for pressing a toothed rack against a pinion, having a pressure piece, wherein the pressure piece can be arranged so as to be displaceable inside a housing and in an axial direction of a centre longitudinal axis, having a bearing element that can be fixed on the housing in an axial direction with respect to the centre longitudinal axis, having a prestressing element that acts in an axial direction, wherein, as a result of the prestressing element being arranged between the bearing element and the pressure piece, the pressure piece is subjected to a prestressing force in an axial direction with respect to the centre longitudinal axis and directed away from the bearing element. In order to be able to reduce the production outlay and/or realize a more compact design, the apparatus is characterized in that a sliding element is arranged on a side, facing away from the prestressing element, of the pressure piece for the purpose of bearing against the toothed rack, wherein the sliding element is designed with a spring function in an axial direction of the centre longitudinal axis in order to compensate tolerances.

According to the present embodiments, noise can be reduced by compensating for clearance caused by the wear of a rack bar support member, assembly convenience can be improved by simplifying a structure, and an installation space can be easily ensured by reducing the overall size of a steering apparatus.

A rack and pinion steering system includes a rack housing, a rack bearing, and an adjuster plug. The rack housing defines a rack housing bore extending along an axis. The rack bearing is disposed within the rack housing bore. The rack bearing has a first bearing portion that is biasingly connected to a second bearing portion. The first bearing portion and the second bearing portion extend along the axis between a first rack bearing end and a second rack bearing end. The adjuster plug is disposed within the rack housing bore. The adjuster plug extends along the axis between a first adjuster plug end that engages the second rack bearing and a second adjuster plug end.
