<p>A rack and pinion assembly, especially suitable for a vehicle steering gear, of the type having a pinion rotatably mounted in a housing meshed with the rack of a rack bar movable longitudinally through the housing wherein the pinion is radially adjusted, and in some embodiments also axially adjusted, by inexpensive plastics material, radial and thrust bearing means at one location in the housing around a free end of the pinion. The bearing means include a radial displaceable plastics ring in bearing relation with a free end portion of the pinion adjacent the pinion teeth either directly or through collars on the pinion portion. The plastics ring may be in one piece and split or may be in several segments and is sufficiently resilient to contract and expand under the influence of applied forces from an adjustable cap in the housing or means on the free end of the pinion.</p> |
