SELF-ADJUSTING RACK SUPPORT ABSTRACT OF THE DISCLOSURE A rack and pinion assembly (10) includes a self- adjusting rack support yoke (23) which eliminates the need for yoke (23) adjustment during initial assembly, and provides automatic adjustment of the support yoke (23) during the life of the assembly (10). A rack and pinion housing (12) receives the pinion (13) which engages the rack (20) supported for movement within the housing (12), the rack (20) engaged by the yoke support (23) biased into engagement by a main spring (40). The support yoke (23) has a recess (25) receiving therein a plug member (60), plug member (60) coupled to the support yoke (23) and having a predetermined separation (33) therebetween maintained by a spring (71), A removable member (50) having a central opening (54) is located within the housing (12) and provides sloped surfaces (52) around the central opening (54) into which extends an end (28) of the plug member (60). Another spring (100) biases a cage member (90) having roller bearing members (80) into locking engagement between the sloped surfaces (52)- and the end (28) of the plug member (60). The predeter- mined separation (33) between the plug member (60) and yoke support (23) allows a certain predetermined amount of movement of the rack (20) relative to the pinion (13), and: upward movement of: the rack (20) and yoke support (23) displaces the plug member (60) upwardly so that the locking members (80) attain an adjusted position for the plug member (60) and yoke support (23).
