Abstract:
(EN) The purpose of the present invention is to increase the braking capability and improve the reliability of a manually-operated brake in a vehicle brake system. A hydraulic fluid replenishment device (40) is provided between first accumulators (15F), (15R) of a manually-operated brake circuit (11) and a second accumulator (25) of an automatic brake circuit (24). The hydraulic fluid replenishment device (40) replenishes the first accumulators (15F), (15R) with hydraulic fluid stored in the second accumulator (25) when a manually-operated brake is being operated by an operator. This controls against slowdown in the rate of brake pressure increase when the manually-operated brake is in operation.
(FR) L'objet de la présente invention est d'augmenter la capacité de freinage et d'améliorer la fiabilité d'un frein actionné manuellement dans un système de frein de véhicule. Un dispositif de remplissage de fluide hydraulique (40) est disposé entre des premiers accumulateurs (15F), (15R) d'un circuit de frein actionné manuellement (11) et un second accumulateur (25) d'un circuit de frein automatique (24). Le dispositif de remplissage de fluide hydraulique (40) remplit les premiers accumulateurs (15F), (15R) avec un fluide hydraulique stocké dans le second accumulateur (25) lorsqu'un frein actionné manuellement est actionné par un opérateur. Ceci permet de lutter contre un ralentissement du taux d'augmentation de la pression de freinage lorsque le frein actionné manuellement fonctionne.
(JA) 人為操作ブレーキ回路(11)の第1アキュムレータ(15F),(15R)と自動ブレーキ回路(24)の第2アキュムレータ(25)との間に作動油補給装置(40)を設ける。この作動油補給装置(40)は、オペレータによる人為操作ブレーキの作動時に、前記第2アキュムレータ(25)に蓄えられた作動油を前記第1アキュムレータ(15F),(15R)に補給する。これにより、人為操作ブレーキ動作時のブレーキ圧の立ち上り速度が遅くなるのを抑えることができる。従って、車両用ブレーキシステムにおいて、人為操作ブレーキによる制動能力を高め、信頼性を向上することができる。
