Abstract: The invention relates to a rack-and-pinion gear mechanism (1), for example for use in a steering mechanism of a motor vehicle, and to a method for the production of the rack-and-pinion gear mechanism (1). The mechanism comprises a housing (101), in which a pinion shaft (102) is mounted so as to be rotatable about an axis (103). The pinion shaft (102) is connected to a rack (110) which is mounted in the housing (101) in such a way as to be longitudinally displaceable. A counter-pressure device (102, 123) compensates for reaction forces between the pinion shaft (102) and the rack (110), having a thrust piece (102) and an adjusting/closing nut (25), between which a spring (123) is supported. The adjusting/closing nut (25) is composed of a material which has a softening/melting point such that the adjusting/closing nut (25) can be softened and/or melted locally while installed in the housing (101) without damaging the housing (101). Softened and/or melted and resolidified partial areas of the adjusting/closing nut (25) are in form-locking engagement with the housing (101).

Abstract: In a rack-and-pinion steering gear for motor vehicles, in which in a steering gear housing a pressure piece is guided within a stub having an axis normal to that of the steering-gear housing so that the pressure piece is longitudinally displaceable in the guide stub. A preloading force acts on the pressure piece at an angle to the direction of motion of the pressure piece such that the pressure piece is held in engagement with a side wall of the stub in either direction of movement of the rack.

Abstract: An apparatus for attachment to the body (240) of a vehicle (12) which has a front, rear and opposite sides and which has steerable wheels. The apparatus comprises a lower part (22) having structure (40, 48) for fixed attachment at each of the opposite sides of the vehicle. A first steering control arm (150) is pivotally connected to the lower part (22) at one side of the vehicle. A second steering control arm (160) is pivotally connected to the lower part (22) at an opposite side of the vehicle. An upper part (24) is connected with the lower part (22). A rack and pinion steering mechanism (10) includes a rack bar (180) movable axially in opposite directions to effect steering movement of the steerable wheels of the vehicle. The steering mechanism (10) includes a chamber (80) through which the rack bar (180) extends. The chamber is defined by surfaces of the upper and lower parts (22, 24).

Abstract: An end cap arranged to slidably support a rack, is inserted into an end of a housing in which the rack is inserted. A cir-clip is interposed between the housing and the end cap to prevent the end cap from being moved axially of the rack. The cir-clip is provided at one end thereof with (i) an inwardly bent curved portion and (ii) a linear portion linearly extending inwardly from the tip of the curved portion and having a tip which always comes in contact with the bottom of an annular groove of the end cap.
