Abstract
A rack and pinion steering gear for a motor vehicle may include a steering pinion, which is connected to a steering shaft and is engaged with a gear rack that is movably mounted in a housing, and may further include a pressure piece arranged in the housing in a pressure piece bore, and which may keep the gear rack engaged free from play with the steering pinion. A pressure piece for a rack and pinion steering gear may include an outer metallic casing inserted with a press fit into the pressure piece bore, at least one elastomer damping element, in particular an elastomer casing, arranged in the metallic casing, with a metallic pressure piece core enclosed by the at least one elastomer damping element.

A rack and pinion steering gear for a motor vehicle, including:
- a steering pinion connected to a steering shaft;
- a gear rack, that is movably mounted in a housing, wherein the steering pinion is engaged with the gear rack, the gear rack including a pressure piece, which is arranged in the housing in a pressure piece bore, and which is configured to keep the gear rack engaged free from play with the steering pinion,
- wherein the pressure piece has an outer metallic casing inserted with a press fit into the pressure piece bore, wherein at least one elastomer damping element is arranged in the metallic casing, that wherein a metallic pressure piece core is enclosed by the at least one elastomer damping element, and wherein an outside of the elastomer damping element is permanently joined to the metallic casing and an inside of the elastomer damping element is permanently joined to the pressure piece core.
A pressure piece for a rack and pinion steering gear for a motor vehicle and configured to be inserted into a pressure piece bore of a housing for mounting a gear rack of the rack and pinion steering gear, the pressure piece comprising:
- an outer metallic casing configured to be inserted with a press fit into the pressure piece bore;
- at least one elastomer damping element arranged in the outer metallic casing;
- and
- a metallic pressure piece core enclosed by the at least one elastomer damping element.
