Abstract

L'invention concerne un mécanisme de direction à crémaillère équipé, pour réduire le jeu entre le secteur denté et la crémaillère, d'une came ne venant en prise avec un doigt de pression monté sur ressorts dans le carter du mécanisme que lorsque le mécanisme de direction se trouve dans la position médiane correspondant à la marche rectiligne du véhicule. Le mécanisme selon l'invention est caractérisé par le fait que la came 29 est prévue de telle sorte sur la crémaillère (piston 16 du cylindre opérateur) montée pivotante dans le carter 7 du mécanisme de direction que le doigt de pression 31 de la crémaillère (piston 16 du cylindre opérateur) tende à effectuer un mouvement de rotation. Application à l'industrie automobile.The invention relates to a rack-and-pinion steering mechanism equipped, in order to reduce the play between the toothed sector and the rack, with a cam which engages with a pressure finger mounted on springs in the housing of the mechanism only when the shift mechanism. steering is in the middle position corresponding to the straight line of the vehicle. The mechanism according to the invention is characterized by the fact that the cam 29 is provided in such a way on the rack (piston 16 of the operating cylinder) pivotably mounted in the housing 7 of the steering mechanism that the pressure finger 31 of the rack ( piston 16 of the operating cylinder) tends to perform a rotational movement. Application to the automotive industry.
