Title
(EN) SENSOR ARRANGEMENT FOR USE WITH AN AIR DISC BRAKE
(FR) ENSEMBLE CAPTEUR DESTINE A ETRE UTILISE AVEC UN FREIN A DISQUE PNEUMATIQUE
Abstract
(EN)
An anti-lock braking system sensor arrangement for use with an air disc brake on an axle, particularly a commercial vehicle axle, wherein a wheel speed sensor is located outside a brake rotor envelope and a sensor exciter is located on an inward-extending portion of the axle hub or on the brake rotor, for example, adjacent to the junction of the rotor hat and its friction portion. The sensor exciter may be integrally formed with the axle hub or the rotor, or may be a separate exciter component affixed thereto. The sensor may be located adjacent to the exciter ring by locating the sensor in an axle flange or in a hole in the air disc brake caliper's mounting bracket. By locating the sensor and sensor exciter in this manner, sensor longevity is enhanced by improved cooling, and potential interference between the sensor and the air disc brake components is eliminated.
(FR)
L'invention concerne un ensemble capteur d'un système de frein anti-verrouillage destiné à être utilisé avec un frein à disque pneumatique sur un essieu, plus spécifiquement sur un essieu de véhicule commercial. Un capteur de vitesse de roue est situé à l'extérieur d'une enveloppe de rotor de frein et un dispositif d'excitation du capteur est situé sur une partie s'étendant vers l'intérieur du moyeu d'essieu ou sur le rotor du frein, par exemple, adjacent à la jonction du chapeau de rotor et de sa partie de friction. Le dispositif d'excitation du capteur peut être formé en une pièce avec le moyeu d'essieu ou le rotor, ou peut être un dispositif d'excitation séparé fixé sur le rotor ou le moyeu d'essieu. Le capteur peut être adjacent à l'anneau du dispositif d'excitation, le capteur étant situé dans une bride d'essieu ou dans un trou situé dans le support de fixation du patin monté en compas du frein à disque pneumatique. En plaçant le capteur et le dispositif d'excitation du capteur de cette façon, la durée de vie du capteur est augmentée grâce à un refroidissement amélioré et une interférence potentielle entre le capteur et les constituants du frein à disque pneumatique est éliminée.
