Title
(EN) BRAKING DEVICE FOR VEHICLE
(FR) DISPOSITIF DE FREINAGE POUR VEHICULE
(JA) 車両用制動装置
Abstract
(EN) [PROBLEMS] A braking device for a vehicle, where a liquid pressure brake can suppress the variation in a braking force applied to a wheel in spite of variation in a friction coefficient between a rotation body and braking means. [MEANS FOR SOLVING PROBLEMS] A braking device for a vehicle has a liquid pressure brake (2)(braking means) for applying a braking force, according to a braking liquid pressure, to a brake disk (20)(rotating body) fixed to a drive wheel (3)(wheel). The braking device is provided with a first feedback mechanism (15-1)(pressure reducing means) for causing a reaction force inputted from the brake disk (20) to the liquid pressure brake (2) when a braking force is applied to act in the direction to reduce the braking liquid pressure.
(FR) L'invention concerne un dispositif de freinage pour véhicule, comprenant un frein hydraulique permettant de supprimer les variations au niveau de la force de freinage appliquée à une roue malgré les variations de coefficient de frottement entre un corps en rotation et un moyen de freinage. Ce dispositif de freinage comprend un frein hydraulique (2) (moyen de freinage) permettant d'appliquer une force de freinage, correspondant à une pression hydraulique de freinage, à un disque de frein (20) (corps en rotation) fixé à une roue d'entraînement (3) (roue). Ce dispositif de freinage est équipé d'un premier mécanisme de rétroaction (15-1) (moyen de réduction de pression) permettant, lorsqu'une force de freinage est appliquée, de diriger une force de réaction transmise au frein hydraulique (2) par le disque de frein (20), de façon que la pression hydraulique de freinage soit réduite.
(JA) 【課題】 液圧ブレーキにおいて、回転体と制動手段との間の摩擦係数の変化にかかわらず、車輪に付与される制動力の変化を抑えることができる車両用制動装置を提供すること。 【解決手段】 駆動輪3(車輪)に固定されたブレーキディスク20(回転体)に対して、制動液圧に応じた制動力を付与する液圧ブレーキ2(制動手段)を備えた車両用制動装置において、制動力付与時に前記ブレーキディスク20から前記液圧ブレーキ2に入力される反力を、前記制動液圧を減じる方向に作用させる第1フィードバック機構15-1(減圧手段)を設けた。
