Abstract:
(EN) Provided is a hydraulic control device having increased reliability. This hydraulic control device is provided with a rear connection hydraulic path, a front connection hydraulic path, a first discharge hydraulic path, a first hydraulic pressure source, a second discharge hydraulic path, a second hydraulic pressure source, and a shutoff valve. The rear connection hydraulic path connects a master cylinder and a rear wheel cylinder. The front connection hydraulic path connects the master cylinder and a front wheel cylinder. The first discharge hydraulic path is connected to the rear connection hydraulic path and the front connection hydraulic path. The first hydraulic pressure source discharges brake fluid to the first discharge hydraulic path. The second discharge hydraulic path is connected to the part of the front connection hydraulic path, which is located between the part of the front connection hydraulic path, to which the first discharge hydraulic path is connected, and the front wheel cylinder. The second hydraulic pressure source discharges brake fluid to the second discharge hydraulic path. The shutoff valve is disposed in the front connection hydraulic path at a position between the part of the front connection hydraulic path, to which the first discharge hydraulic path is connected, and the part of the front connection hydraulic path, to which the second discharge hydraulic path is connected.
(FR) L'invention concerne un dispositif de commande hydraulique présentant une plus grande fiabilité. Ce dispositif de commande hydraulique comprend un circuit hydraulique de raccordement arrière, un circuit hydraulique de raccordement avant, un premier circuit hydraulique d'évacuation, une première source de pression hydraulique, un second circuit hydraulique d'évacuation, une seconde source de pression hydraulique, et une valve d'arrêt. Le circuit hydraulique de raccordement arrière relie un maître-cylindre et un cylindre de roue arrière. Le circuit hydraulique de raccordement avant relie le maître-cylindre et un cylindre de roue avant. Le premier circuit hydraulique d'évacuation est relié au circuit hydraulique de raccordement arrière et au circuit hydraulique de raccordement avant. La première source de pression hydraulique évacue le fluide de frein vers le premier circuit hydraulique d'évacuation. Le second circuit hydraulique d'évacuation est relié à la partie du circuit hydraulique de raccordement avant, qui est situé entre la partie du circuit hydraulique de raccordement avant, auquel le premier circuit hydraulique d'évacuation est relié, et le cylindre de roue avant. La seconde source de pression hydraulique évacue le fluide de frein vers le second circuit hydraulique d'évacuation. La valve d'arrêt est disposée dans le circuit hydraulique de raccordement avant à une position entre la partie du circuit hydraulique de raccordement avant, auquel le premier circuit hydraulique d'évacuation est relié, et la partie du circuit hydraulique de raccordement avant, auquel le second circuit hydraulique d'évacuation est relié.
(JA) 信頼性を向上できる液圧制御装置を提供する。 液圧制御装置は、リア側接続液路、フロント側接続液路、第1吐出液路、第1液圧源、第2吐出液路、第2液圧源、並びに遮断弁を備える。リア側接続液路は、マスタシリンダとリア側ホイルシリンダとを接続する。フロント側接続液路は、マスタシリンダとフロント側ホイルシリンダとを接続する。第1吐出液路は、リア側接続液路およびフロント側接続液路に接続される。第1液圧源は、第1吐出液路にブレーキ液を吐出する。第2吐出液路は、フロント側接続液路における、第1吐出液路が接続される位置とフロント側ホイルシリンダとの間に接続される。第2液圧源は、第2吐出液路にブレーキ液を吐出する。遮断弁は、フロント側接続液路における、第1吐出液路が接続される位置と第2吐出液路が接続される位置との間に配置される。
