Title
(EN) MECHANISM FOR ACTUATING A VEHICLE PARKING BRAKE
(FR) MECANISME D'ACTIONNEMENT DU FREIN DE STATIONNEMENT D'UN VEHICULE
Abstract
(EN)
The mechanism comprises a pivotable hand operated actuating lever (101) which engages an upwardly drive plate (102) biassed upward by a spring (122). The drive plate (102) moves an output rod (103) connected to a brake cable. The output rod (103) is held by a lock plate (104) which is released by a push rod (10) passing through the lever (101). The mechanism automatically adjusts for variation in the brake cable tension by the action of the spring (122) on an abutment plate (130) fixed to the end of the output rod (103). Additional self-adjustment mechanisms are described (Figures 4 to 7). Further hand or foot operated brake actuating mechanisms are also described (Figures 1 to 3 and Figure 10), together with additional hydraulic or manually operated mechanisms for release of the lock plate (104). A mechanism is described which signals that the brake has been applied (Figure 11).
(FR)
Mécanisme comprenant un levier pivotant d'actionnement manuel (101) qui met en prise une plaque d'entraînement supérieure (102) sollicitée vers le bas par un ressort (122). La plaque d'entraînement (102) déplace une tige de sortie (103) reliée à un câble de frein. Ladite tige de sortie (103) est retenue par une plaque de blocage (104) qui est libérée par une tige de poussée (10) traversant le levier (101). Le mécanisme s'adapte automatiquement aux variations de la tension du câble de frein au moyen de l'action du ressort (122) sur une plaque de butée (130) fixée sur l'extrémité de la tige de sortie (103). Des mécanismes autoréglables supplémentaires sont également décrits (Figures 4 à 7). L'invention concerne aussi des mécanismes d'actionnement du frein à commande manuelle ou par le pied (Figures 1 à 3 et figure 10) ainsi que des mécanismes supplémentaires à commande manuelle ou hydraulique permettant de libérer la plaque de blocage (104). Un mécanisme signalant que le frein a été tiré est également décrit (Figure 11).
