A power assisted steering system includes a steering assembly and a power assist assembly. The power assist assembly includes a motor having an output shaft that is connected to the steering assembly. A target disc is connected to the output shaft for rotation therewith. A control unit has a printed circuit board including at least one sensor supported thereon. The sensor is responsive to rotation of the target disc for generating a signal. The controller is responsive to the sensor signal for controlling the operation of the motor.

A rack bushing seal assembly for a rack and pinion steering assembly that includes a bushing, a bushing liner and a locking material. The bushing defines an annular recess on an outer surface of the bushing. The bushing liner is positioned within the bushing. The locking material is positioned within the annular recess for retaining the rack bushing seal assembly within a rack tube. A rack bushing seal assembly also includes a bushing having a first annular flange with a pressure port formed therein, and a first tube portion with a channel portion formed therein, wherein the pressure port is in fluid communication with the channel portion. The rack bushing seal assembly also includes a bushing liner having a second annular flange and a second tube portion, the bushing liner being positioned within the first tube portion of the bushing. A rack tube is placed in abutting arrangement with the first annular flange of the bushing wherein the channel portion is in fluid communication with the rack.

Seal assembly for a rack and pinion steering assembly

An apparatus () for turning steerable wheels of a vehicle comprises a housing () that defines a fluid chamber (). A rack bar () extends longitudinally through the housing () and is connectable with the steerable wheels of the vehicle. The rack bar () is movable relative to the housing () for turning the steerable wheels. A piston assembly () is fixedly attached to the rack bar () and sealingly engages the housing (). The piston assembly () divides the fluid chamber () into first and second chamber portions (and). A fluid source () directs fluid toward one of the first and second chamber portions (or) for creating a differential pressure between the first and second chamber portions (and). The piston assembly () and the rack bar () move relative to the housing () in response to the differential pressure. The piston assembly () includes structure () for dampening fluid pulsations emanating from the fluid source ().

A power steering apparatus ( ) includes a housing ( ) defining a chamber ( ) for holding power steering fluid. The housing ( ) has an opening ( ) defined by a projection ( ) integrally formed on the housing. A conduit ( ) extends into the opening ( ) and is connected with the projection ( ) on the housing ( ). A connector assembly ( ) connects the conduit ( ) with the projection ( ) on the housing ( ). The connector assembly ( ) includes a clip ( ) having a base ( ) with an opening ( ) and a plurality of resilient fingers ( ) extending from the base. Either the conduit ( ) or the projection ( ) extends through the opening ( ) in the base ( ) and engages the base. The fingers ( ) engage the other of the conduit ( ) and the projection ( ).

A hydraulic power assist steering system ( ) for a vehicle having steerable wheels comprises a housing ( ) and a rack ( ). The system also comprises a fluid motor ( ) for moving the rack ( ). The fluid motor ( ) includes a piston ( ) fixedly connected to the rack ( ) and a pump ( ). The piston ( ) has first and second opposite end faces ( ) against which hydraulic fluid is directed by the pump ( ) to effect movement of the piston ( ), and thereby the rack ( ), relative to the housing ( ). The piston ( ) has a wall ( ) including a first end portion ( ) connected with the rack ( ) at a first axial location along the rack, a second end portion ( ) connected with the rack at a second axial location along the rack, and a central portion ( ) extending between and interconnecting the first and second end portions of the wall. The central portion ( ) of the wall ( ) has an outer peripheral groove ( ) for receiving a seal ring ( ) for engagement with the housing ( ). The first end portion ( ) and the second end portion ( ) and the central portion ( ) of the piston ( ) define a cavity ( ) in the piston. The cavity ( ) has an annular configuration extending around the rack ( ) inside of the wall ( ).
