The invention provides an air-assisted hydraulic control air valve for automobile braking. The air-assisted hydraulic control air valve comprises a shell, a clutch hydraulic piston, a braking hydraulic piston and a braking piston. A clutch hydraulic cavity, a clutch air cavity, a brake hydraulic cavity and a brake air cavity are arranged in the shell, a clutch hydraulic piston is arranged in the clutch hydraulic cavity, a brake hydraulic piston is arranged in the brake hydraulic cavity, and a brake piston is arranged in the brake air cavity. The clutch hydraulic piston, the brake hydraulic piston and the brake piston are all provided with gas channels, and when the brake pedal is in a clutch state, the clutch hydraulic piston is pushed by hydraulic oil to move along the clutch hydraulic cavity, so that the gas channels in the clutch hydraulic piston are communicated with the clutch gas cavity for clutch gas taking. When the brake pedal is in a brake state, the brake hydraulic piston is pushed by hydraulic oil to move along the brake hydraulic cavity, so that the gas channel on the brake hydraulic piston is communicated with the brake gas cavity to assist in pushing the brake to move. The pedal force of automobile braking can be reduced.

    本发明提供一种用于汽车制动的气助式液控气阀,包括:壳体、离合液压活塞、制动液压活塞和制动活塞。壳体内设置有离合液压腔、离合气腔、制动液压腔和制动气腔,离合液压腔内设有离合液压活塞,制动液压腔内设有制动液压活塞,制动气腔内设有制动活塞。离合液压活塞、制动液压活塞和制动活塞均设有气体通道,在制动踏板处于离合状态时,离合液压活塞受液压油推动沿离合液压腔运动,使离合液压活塞上的气体通道与离合气腔相导通,以供离合取气。在制动踏板处于制动状态时,制动液压活塞受液压油推动沿制动液压腔运动,使制动液压活塞上的气体通道与所述制动气腔相导通,以助力推动制动活活运动。本发明能降低汽车制动的踏板力。
