Definitions

  • This invention relates to vehicle brakes that have a stator connected to a chassis, an actuator that energises and de-energises the brake, a sacrificial friction member (hereinafter called a lining) , a rotor that is connected to a wheel, and arranged such that energising the actuator has the action of bringing the lining into contact with the rotor, the fi*ictional torque produced and the actuator, reacting against the stator.
  • a sacrificial friction member hereinafter called a lining
  • This invention is simpler and more reliable than self adjustment devices presently known.
  • actuator 53 Depressurisation of actuator 53 permits seal 57 to retreat piston 56 from rotor 54 and the strains in the brake components can knock the linings back until plate 62 contacts circlip 68.

Abstract

Dispositif (11) de réglage de freinage pour véhicule comprenant un frein de véhicule ayant un stator (1), un système d'actionnement (3), un rotor (8) et des garnitures (7), le réglage des garnitures (7) par rapport au rotor (8) se faisant au moyen d'une rondelle ou d'un collier en forme de C (14) ou d'un ressort (104) calé unidirectionnellement sur une tige (13), conjointement avec un dispositif (22, 23) limitant le désenclenchement. On peut incorporer dans le frein pour véhicule un frein à main (27) agissant par l'intermédiaire de la pièce de serrage (14) et de la tige (13). Une autre version destinée à des cycles à pédale et à moteur, utilisant l'actionnement par cable est également décrite.
