Abstract

The present invention relates to a brake vacuum auxiliary device for automobiles. The brake vacuum auxiliary device for automobiles comprises a monoblock rotary vane pump, an exhaust filtering and oil feeding device, a tee joint connected with a booster assembly, a vacuum switch and a power controller. The monoblock rotary vane pump is connected with the exhaust filtering and oil feeding device, and the monoblock rotary vane pump is connected with the tee joint by a vacuum pipe provided with a check valve. One end of the power controller connected with a power supply is connected with a motor, and the other end is connected with the vacuum switch arranged below the tee joint. The device is an engine capable of being separated from an automobile, having vacuum stability functions. The device can provide the brake vacuum booster with a reliable, stable and independent vacuum source, and make the brake vacuum booster constantly lie in a reliable work state.

Description

technical field [0001] The invention relates to a vacuum auxiliary device used in an automobile brake system, in particular to an automobile brake vacuum auxiliary device. Background technique [0002] In the automotive braking system, especially in the hydraulic dual-pipeline braking system, brake vacuum boosters are widely used, but the vacuum source provided by the automobile comes from the intake manifold of the gasoline engine of the automobile. , because the speed of the engine has a great influence on the degree of vacuum it produces. Therefore, when the engine is running at high speed, idling, or the engine is suddenly turned off, the vacuum degree is unstable, which directly affects the normal use of the vacuum booster and greatly affects the braking effect of the car; especially for many hybrid cars, electric The continuous advent of automobiles has canceled the gasoline engine and the vacuum source, which poses a problem to the vacuum system of the automobile. H...
