Abstract: A radial and thrust bearing for a shaft has a plastics tubular bushing composed of an axially slotted bearing ring supporting a shaft carried bearing component and connected at one end to a surrounding axially slotted thinner flexible skirt for seating in a housing to locate the bearing ring. The axial slots are circumferentially spaced, extend radially almost through the bushing with alternate inner and outer blind ends dividing the bushing into circumferential segments alternately connected at their inner and outer peripheries to accommodate radial contraction and expansion of the bushing so that wide tolerances may be permitted in the dimensions of the shaft bearing component and the housing seating. The bushing may be a continuous ring, may be a split ring, or may be composed of several discreet ring segments and the bearing ring portion thereof may be fixedly clamped in a housing.

Abstract: A braking system in which pressure from a master cylinder acting in slave cylinders at the brakes carries initial or low-force braking dependent on the driver''s pedal force, there being a mechanical feed-back mechanism which increases the braking pressure in accordance with the mechanical force resulting from brake reaction in the vehicle, e.g. torque or drag. The hydraulic braking force is therefore augmented by fed-back force and in that sense provides a servo effect.

Abstract: 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.

Abstract: Rack and pinion automotive steering gear with shock absorbing means between the rack bar and rack for damping transfer of road shocks from the rack bar to the pinion. The rack bar has a reduced diameter portion receiving a rack sleeve and shock absorbing means, such as resilient washers, are interposed between the ends of the sleeve and shoulders of the rack bar. The rack bar is preferably cylindrical, and the reduced diameter portion thereof has an eccentric axis. The rack sleeve is preferably cylindrical with an eccentric bore so located to provide a thick rack tooth wall and to position the external cylindrical sleeve surface concentric and flush with the main rack bar. The bar and sleeve are slidably supported in a spring biased yoke.

Abstract: Apparatus for use in a power-steering system including a pinion and a cooperating rack for use in association with a powerassisting dual-acting pressurized fluid-operated servomotor. A steering column is connected to the pinion for limited relative rotation through a torsionally resilient coupling. The pinion is connected for joint rotation to one of a pair of relatively rotatable valve members of a fluid flow valve which controls the flow of pressurized fluid to and from the opposite ends of the servomotor. The steering column is connected to the other valve members through a rigid virtually nonstraining rod.
