Abstract
(EN)
The fork (10) comprises a pair of legs (16) adapted to sup¬ port for rotation a wheel (18) and a hydraulic braking device including a pair of hydraulic braking actuators (26) , each of which is mounted on a respective leg (16) and is provided with a friction member (38) . Each braking actuator (26) is arranged to press the respective friction member (38) against a braking surface (20a) of the wheel (18) so as to exert a braking force. According to the invention, each leg (16) has, on the side facing the wheel (18) , a side abutment surface (24), a lower support surface (50) and a front stop surface (52), and each hydraulic actuator (26) has an outer side face (28) arranged against the side abutment surface (24), a lower face (32) resting on the lower support surface (50), a front face (34) retained longitudinally by the front stop surface (52) and an inner side face (30) on which the friction member (38) is mounted.
(FR)
La fourche (10) comprend une paire de branches (16) adaptées pour supporter en rotation une roue (18) et un dispositif à frein hydraulique comprenant une paire d'actionneurs de freinage hydraulique (26), chacune desquelles étant montée sur une branche respective (16) et étant pourvue d'un élément de friction (38). Chaque actionneur de freinage (26) est agencé de manière à compresser l'élément de friction respectif (38) contre une surface de freinage (20a) de la roue (18) afin d'exercer une force de freinage. L'invention est caractérisée en ce que chaque branche (16) présente, sur le côté faisant face à la roue (18), une surface de contact latérale (24), une surface support inférieure (50) et une surface de retenue avant (52), et en ce que chaque actionneur hydraulique (26) présente une face latérale extérieure (28) agencée à l'encontre de la surface de contact latérale (24), une face inférieure (32) reposant sur la surface support inférieure (50), une face avant (34) maintenue longitudinalement par la surface d'arrêt avant (52) et une face latérale intérieure (30) sur laquelle est monté l'élément de friction (38).
