Abstract: A rack and pinion gear system in a gear casing for vehicle steering has a spring biased rack against the pinion at one side of the pinion to maintain pinion engagement with the rack. On the other side of the pinion is a generally semicircular bracing bushing encompasssing the pinion and slightly spaced therefrom to brace the pinion in event of bending due to operational stresses. The bracing bushing is carried for support against the gear casing and secured in any suitable manner or may be cast as part of it.

Abstract: A process for the manufacture of a rack, specially a rack having variable transmission, wherein the teeth of the rack have in the central area a profile different from that of the outer portions. The rack is formed from a blank in a press having an upper die and a lower die. The rack is manufactured by cold-mold pressing and one die portion carries out, during the pressing operations, a wobbling movement over the blank. In an apparatus for carrying out the process, a die forms the negative mold for the lower portion of the rack to be manufactured. In the other die is molded in negative mold the toothed profile of the rack to be manufactured.

Abstract: Parallel ball bearing arrays are utilized in a pressure support means for a rack to reduce friction of a stationary pressure means supporting a moving rack in engagement with a drive pinion. The rack and a pressure pad have face to face coacting ball races on each side of the rack and so oriented that median planes of a pair of facing races are at an angle to the median plane of the rack. Accordingly, a train of balls on each side of the rack in the respective pair of coacting races has a median plane at an angle to the median plane of the rack on each side of the rack. Such orientation gives support normal to the rack and laterally as well, at the area where the rack engages the pinion.

Abstract translation: 平行球轴承阵列用于齿条的压力支撑装置，以减少支撑与驱动小齿轮啮合的移动齿条的静止压力装置的摩擦力。 机架和压力垫在机架的每一侧具有面对面的联合球赛，并且使得一对面对的座圈的中间平面与机架的中间平面成一定角度。 因此，在一对共同种族中的架子的每一侧上的一列滚珠具有与架子的每一侧上的齿条的中间平面成一个角度的中间平面。 这样的定向在机架与小齿轮啮合的区域也提供了与机架垂直的横向支撑。
