Abstract

The invention relates to a mechanical vacuum booster with an emergency braking function and belongs to the automobile braking field. A control valve assembly of the mechanical vacuum booster comprises such parts as a valve body, an input link, a filter screen spring seat, a conical spring, a spring seat, a compression spring, a vacuum leather cup, a trigger mechanism, a trigger mechanism spring, a plunger, a locking plate, a locking plate spring, a valve block, a scale plate, a reaction plate, an output link, an elastic collar, as well as a rubber seal ring, a rear shell body, a diaphragm, a diaphragm plate, a front shell body, a large return spring and the like. The mechanical vacuum booster has the advantages of novel structure and low cost; and provided that the vacuum booster meets a certain input power requirement, the vacuum booster can output relatively huge applied force on a main braking cylinder when a driver performs emergency braking, and the vacuum booster maintains output pressure of the main cylinder on the condition of reducing input force, thus shortening the braking distance of the whole automobile and being especially effective for unskilled drivers and drivers who hesitate to brake.

Description

technical field

[0001] The present invention relates to a brake vacuum booster, more specifically, to such a brake vacuum booster: the vacuum booster can ensure a certain input power under the condition of emergency braking, and obtain a Increased output force with pressure hold. Background technique

[0002] The vacuum booster is a key component in the car braking system. Its function is to use the vacuum generated by the engine intake manifold or the auxiliary vacuum pump to amplify the force of the brake pedal, thereby reducing the force used by the driver for braking. The main principle of the vacuum booster is that the booster has two working chambers, the front and the rear. When the booster is working, the pressure difference between the two working chambers is generated to realize the boosting effect. The two working chambers are separated by the valve body, the diaphragm disc, and the diaphragm.

[0003] When the driver applies emergency braking, the conventional v...
