れたパワーピストンのフロント側真空室に負圧を導入し
、リア側圧力室に大気を導入して−前記真空室と圧力室
との差圧によりパワーピスト ンに推力を発生
−させ該推力を前記パワーピスト外に設けられた出力軸
に伝達するブレーキブースタの前記圧力室またはマスク
シリンダとホイールブレーキとの間の配管途中に切換弁
を接続し゛、該切換弁の切換により制動力の保持あるい
はブレーキブースタによる自動的制動力の発生を行なわ
せる車両ブレーキ装置であって車両の車輪の速度変化が
所定値より大きなときには前記切換弁の切換勲′
作を不能にしたことを特徴とする車両ブレーキ装置。Negative pressure is introduced into the front vacuum chamber of the power piston, which is displaceably provided in the shell body via a diaphragm, and atmospheric air is introduced into the rear pressure chamber. A switching valve is connected in the middle of the piping between the pressure chamber or mask cylinder of the brake booster that generates thrust in the power piston and transmits the thrust to an output shaft provided outside the power piston and the wheel brake, The vehicle brake system maintains braking force or automatically generates braking force by a brake booster by switching the switching valve, and when the change in speed of the vehicle wheels is larger than a predetermined value, the switching valve is switched.
A vehicle braking device characterized by disabling operation.
