Abstract

The invention relates to an automobile brake system. The bevel gear drive adjusting type brake system for the new energy automobile comprises a jacking rod, a pedal, a brake reinforcement hydraulic cylinder, a brake reduction hydraulic cylinder, a bi-directional hydraulic pump, a driven bevel gear, a drive bevel gear, an adjustable-speed motor which drives the drive bevel gear, a control module and a speed sensor which detects the speed of the jacking rod. A rod cavity of the brake reinforcement hydraulic cylinder communicates with a rod cavity of the brake reduction hydraulic cylinder through a pipeline, and a rodless cavity of the brake reinforcement hydraulic cylinder communicates with a rodless cavity of the brake reduction hydraulic cylinder through the bi-directional hydraulic pump. The driven bevel gear and a rotating shaft of the hydraulic pump are connected together, and the drive bevel gear and the driven bevel gear are engaged together. The bevel gear drive adjusting type brake system for the new energy automobile has the beneficial effects that the feeling of extruding the pedal can be automatically adjusted in use, and the problem that an existing brake pedal feeling cannot be adjusted later is solved.

Description

technical field [0001] The invention relates to an automobile braking system, in particular to a bevel gear driven and adjustable new energy automobile braking system. Background technique [0002] In the traditional braking system (braking system), the braking is achieved by the driver applying force on the brake pedal, which is amplified and converted into hydraulic pressure by the vacuum booster system, and acts on the brake to achieve braking. Now the car The vacuum booster system used above is composed of a vacuum booster with a brake master cylinder, a vacuum tank, a vacuum pump, and a vacuum tube. The vacuum booster with a brake master cylinder uses the pressure difference between the vacuum and the atmosphere to apply the driver to the pedal. The brake force is amplified, and the force is transmitted to the brake master cylinder to establish hydraulic pressure, realize the conversion of pedal force to hydraulic pressure, and then achieve braking. Among them, the vac...
