Push device with clearance compensation for rack-and-pinion steering of a motor vehicle
Abstract:
The invention relates to a push device (8) which includes a rotary pad (10) in which the inner periphery (11) is off-center relative to the outer periphery (12) and applied to the rear (9) of the rack (3) which is thereby pushed towards the teeth of the steering pinion (5). A clearance compensation mechanism (17) includes a thrust member (19) pressed against a radial arm (18) of the pad (10) by a compression spring (20) inserted between said member and an element (23) secured to the support (13) of the pad (10). A mobile stop (21) rotatably mounted relative to the element (23) comprises toothings having staggered gear teeth cooperating with notches of the thrust member (19). The stop (21) is connected to the element (23) by means of a torsion spring (22). The notches successively cooperate with the staggered teeth.
Abstract(Chinese):

本发明涉及一种推动装置（8），其包括旋转垫（10），其中内周（11）相对于外周（12）偏心，并且施加到齿条的后部（9） 3），其被推向转向小齿轮（5）的齿。 间隙补偿机构（17）包括通过插入在所述构件和固定到支撑件的元件（23）之间的压缩弹簧（20）压靠垫（10）的径向臂（18）的推力构件（19） 13）。 相对于元件（23）可旋转地安装的移动式止动件（21）包括与推力构件（19）的凹口配合的具有交错齿轮齿的齿。 止动件（21）通过扭簧（22）连接到元件（23）。 凹槽先后与交错的牙齿配合。
