Abstract

The invention relates to an air booster with a brake master cylinder. A front shell (35) of the air booster is connected with the brake master cylinder (20), vehicles with requirement of hydraulic brake and unable to meet requirements of braking force by adopting an air booster with a brake master cylinder assembly in the prior art are replaced, the braking force can be exponentially enlarged through air boosting, and relative size of the air booster is smaller than that of the vacuum booster with the brake master cylinder and can better meet the installation requirements; an input push rod (3) in the air booster can stop at optional positions during pushing, and when pressure force and hydraulic pressure are balanced, an air inlet valve (C) is closed, and a follow-up control function of the air booster with the brake master cylinder can be accordingly realized. In addition, an exhaust pipe (38) is connected with a silencing check valve through a hose outside a cab, so that dust particles can be effectively prevented from entering the cavity of the booster, the cavity is kept clean, and meanwhile, exhaust noise of the cab is reduced.

Description

technical field [0001] The invention relates to a booster braking device used in an automobile hydraulic braking system, in particular to a pneumatic booster with a brake master cylinder. Background technique [0002] Vacuum boosters are mostly used in the braking systems of transmission vehicles. However, for light vehicles with large tonnage, the vacuum booster system has insufficient braking force. Big and not safe. Therefore, in the prior art, a pneumatic booster is used to replace the original vacuum booster technology. [0003] Pneumatic booster with brake master cylinder is the key component in the automobile hydraulic brake mechanism, installed in the cab and directly connected to the brake pedal. The principle is: the pneumatic booster converts the compressed air pressure energy into hydraulic energy, and transmits it to the brake cylinder or brake caliper to realize the brake of the car. When the driver manipulates the brake pedal, the brake master cylinder asse...
