Abstract
(EN)
Provided is a hydraulic control unit that can resist an external force more than in the past when mounted on a saddle-type vehicle. A hydraulic control unit (1) comprises: a base (10) in which is formed an internal flow channel in which brake fluid flows; a retraction valve and a relaxation valve that open and close the internal flow channel during anti-lock brake control; a first coil (61) serving as a drive source for the retraction valve; a second coil serving as a drive source for the relaxation valve; and a circuit board (36) that is electrically connected to the first coil (61) and the second coil, and that controls energization of the first coil (61) and the second coil. The base (10) is held by a front fork (216). When a saddle-type vehicle in which the hydraulic control unit (1) is installed is viewed from the front, the circuit board (36) is located behind the front fork (216) and the base (10), and the first coil (61) and the second coil are erected from a rear surface of the base (10).

L'invention concerne une unité de commande hydraulique qui peut davantage résister à une force externe que dans le passé lorsqu'elle est montée sur un véhicule de type à selle. Une unité de commande hydraulique (1) comprend : une base (10) dans laquelle est formé un canal d'écoulement interne dans lequel s'écoule un liquide de frein ; une soupape de rétraction et une soupape de détente qui ouvrent et ferment le canal d'écoulement interne pendant la commande de frein antiblocage ; une première bobine (61) servant de source d'entraînement pour la soupape de rétraction ; une seconde bobine servant de source d'entraînement pour la soupape de détente ; et une carte de circuit imprimé (36) qui est électriquement connectée à la première bobine (61) et à la seconde bobine, et qui commande l'excitation de la première bobine (61) et de la seconde bobine. La base (10) est soutenue par une fourche avant (216). Lorsqu'un véhicule de type à selle dans lequel l'unité de commande hydraulique (1) est installé est vu depuis l'avant, la carte de circuit imprimé (36) est située derrière la fourche avant (216) et la base (10), et la première bobine (61) et la seconde bobine se dressent à partir d'une surface arrière de la base (10).
