Title
(EN) ELECTRIC PARKING BRAKE DEVICE
(FR) DISPOSITIF DE FREIN DE STATIONNEMENT ÉLECTRIQUE
(JA) 電動パーキングブレーキ装置
Abstract
(EN)
This electric parking brake device is provided with a brake cable of which one end is provided with an engaging piece engaged with a parking brake lever, and an electric actuator that has a drive shaft of which one end is linked to the other end of the brake cable and that can cause the drive shaft to reciprocate in an axial direction, wherein an insertion hole (50) is provided in one of a drive shaft (39) and a joint (48) secured to the brake cable, an insertion shaft part (39a) inserted through the insertion hole (50) is coaxially provided to the other of the joint (48) and the drive shaft (39), and an annular engaging member (49) that can be inserted through the insertion hole (50) along with the insertion shaft part (39a) is interposed between the inner periphery of the insertion hole (50) and the outer periphery of the insertion shaft part (39a) so as to link the joint (48) and the drive shaft (39). It is thereby possible to make the work of linking the brake cable and the drive shaft of the electric actuator easier and to increase assemblability.

L'invention concerne un dispositif de frein de stationnement électrique, lequel dispositif comporte un câble de frein dont une extrémité comporte une pièce de prise venant en prise avec un levier de frein de stationnement, et un actionneur électrique qui a un arbre d'entraînement dont une extrémité est reliée à l'autre extrémité du câble de frein, et qui peut provoquer un mouvement de va-et-vient de l'arbre d'entraînement dans une direction axiale, un trou d'insertion (50) étant réalisé dans l'un d'un arbre d'entraînement (39) et d'un raccord (48) fixé au câble de frein, une partie d'arbre d'insertion (39a) insérée à travers le trou d'insertion (50) étant disposée de façon coaxiale sur l'autre du raccord (48) et de l'arbre d'entraînement (39), et un élément de prise annulaire (49) qui peut être inséré à travers le trou d'insertion (50) avec la partie d'arbre d'insertion (39a) étant interposé entre la périphérie interne du trou d'insertion (50) et la périphérie externe de la partie d'arbre d'insertion (39a) de façon à relier le raccord (48) et l'arbre d'entraînement (39). Il est par conséquent possible de rendre le travail de liaison du câble de frein et de l'arbre d'entraînement de l'actionneur électrique plus facile et d'accroître l'aptitude à l'assemblage.
