Abstract

The invention relates to an automobile brake device, in particular to an automobile vacuum-brake assisting device. The automobile vacuum-brake assisting device comprises an engine work induction switch, a vacuum pump, a brake lamp switch, a storage battery and an electromagnetic switch, and successfully solves the problem that braking can not be effectively achieved after an automobile adopting an oil braking system shuts down suddenly. According to the invention, a vacuum-brake assisting device is additionally arranged on the conventional automobile adopting the oil braking system, so that after an engine suddenly shuts down, pressure difference exists in the housing of a brake booster when the driver tramples the brake pedal, and then the driver can cushily brake the automobile by virtue of the pressure difference. Therefore, the probability of safety accidents caused after sudden flameouts of the automobile is greatly lowered, and the automobile vacuum-brake assisting device is ingenious in structure and small in size, and can not occupy too large space when being mounted in the automobile, thereby being worthy of popularization.

Description

technical field [0001] The invention relates to an automobile brake device, in particular to an automobile vacuum brake auxiliary device. Background technique [0002] The brake system of light vehicles such as cars and minibuses generally adopts an oil brake system. The oil brake system includes a brake booster. The brake booster is connected to the intake pipe of the engine through a pipeline with a vacuum check valve on it. The car of the system brakes by using the pressure difference in the brake booster housing caused by the engine's work and air intake during driving. Without the pressure difference, the driver needs to put in a lot of effort to step on the brake pedal if he wants to stop, and often the driver puts in a lot of effort to step on the brake pedal, but the car is not braked effectively, especially when the car suddenly turns off when climbing a steep slope Finally, if the car cannot be stopped in time, it may cause a safety accident. Although the hand bra...
