DISPOSITIF DE POUSSOIR AVEC COMPENSATION DE JEU POUR DIRECTION A CREMAILLERE DE VEHICULE AUTOMOBILE

摘要

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.
