Abstract: The assembly comprises a rack (2) and a pinion (1) each having an axis of symmetry (7, 8) perpendicular to each other in their transversal section. The rack (2) is located in a chamber (6) provided within a rigid body (5), this chamber (6) having a partly cylindrical inner wall (9), the axis of symmetry of the chamber (6) being merged into the rack axis (8). The track (2) includes a front face engaged with the pinion (1) and a rear face opposite the front face, this rear face comprising two lateral tapered sides (15) converging toward the rack axis (8) and an extending rib (13) having flat lateral sides (17) parallel to the rack axis. Within the rigid body (5), is provided a pair of members (31, 32) disposed symmetrically with respect to the rack axis (8), each member (31, 32) being rotatively slideable along the cylindrical inner wall (9), each of the members engaging one of the lateral tapered sides (15) at about one point and one of the lateral flat sides (17) at about one point, and further including a spring (4) located between ends of the members (31, 32) and urging the ends in opposite directions in such a way that the members (31, 32) bear on the rib (13) to generate an anti-ungearing force applied to the lateral tapered sides (15) of the rack (2).

Abstract: A variable ratio rack and pinion gear having a rack bar (1) the rack (8) of which engages with the pinion (10) so that rotation of the pinion displaces the rack member (1) longitudinally relative to the housing (6). A yoke (25) supports the member (1) with its teeth in engagement with the pinion and straddles the member (1) to restrain displacement of that member relative to the housing (6) in a direction parallel to the axis of rotation for the pinion (10). The rack member is restrained from rotation relative to the housing, and (1) has a longitudinally extending non-rectilinear grooved track of one or more curved portions (14) which is engaged by a peg (17) rotatably carried in a mounting block (21). The block (21) retains the yoke (25) in the housing with the peg (17) located within and extending through the yoke (25). The peg (17) engages with the track (14) so that during longitudinal displacement of the rack member (1) the reaction between the groove (14) and peg (17) imparts limited controlled rotation to the member (1) to vary the ratio of the gear. Consequently, by appropriately shaping the track the gear assembly can be provided with a predetermined variable gear ratio. For example, the track may be a helix of variable pitch to provide the variable gear ratio. The peg can rotate in its mounting block (21) to alleviate friction between the peg and rack member (1) during displacement of the latter and can be spring biased to urge and support the rack member for engagement with the pinion.In a modification, the grooved track (14) is engaged by the peripheral edge of a rotatably mounted roller or wheel located within the yoke so that engagement between the roller and rack member (1) imparts rotation to the rack member to vary the gear ratio during displacement of the rack member.The teeth of the rack member can extend part way only around the periphery of that member while the non-toothed peripheral portion provides a slideway within which the groove (14) is machined and with which the yoke (25) slidably engages.

Abstract: Disclosed is a rack and pinion mechanism used in a steering device of a vehicle, in which when a pinion is engaged with rack teeth at an axially middle part of a rack bar, the rack bar is supported by supporting surfaces of a support yoke in the form of surface contact. When the pinion is engaged with the rack teeth at a part other than the axially middle part of the rack bar, on the contrary, the rack bar is supported by a rotary bearing mounted on the support yoke. Therefore, when a vehicle runs rectilinearly, the sliding resistance of the rack bar becomes large and the handle is stabilized, while when the vehicle turns, the sliding resistance becomes small and handling is made light because the rack bar is supported by a bearing.
