Problems solved by technology

When a car needs to use a vacuum brake source, due to structural limitations, the vacuum pump installed on the generator often cannot meet the vacuum requirements of the brake system, especially in the case of continuous braking, which will cause the vacuum to be replenished too slowly and make the brake Poor dynamic performance, affecting the braking effect of the car

Abstract

The invention discloses a gearbox-driven vacuum braking device which comprises a vacuum pump, a gearbox and a transfer box, wherein the transfer box is used for connecting the vacuum pump and the gearbox, the transfer box is installed on the power takeoff opening of the gearbox, the transfer box and the vacuum pump are integrated into a whole, or the transfer box and the vacuum pump are independently installed. On the basis of a traditional vacuum-assisted braking system, one vacuum pump is additionally arranged on the gearbox, a more reliable vacuum degree is supplied by adopting the gearbox-driven vacuum pump, and the device has simple and reasonable structure as well as convenient and flexible installation, avoids the situations that vacuum is adopted as the braking energy source of a vehicle and insufficient vacuum occurs when only one generator-driven vacuum pump exists, greatly increases the vacuum supplying speed of the braking system, guarantees vacuum supply, and improves the safety performance of the whole vehicle.

Description

technical field [0001] The invention relates to a vacuum power-assisted braking system, in particular to a gearbox-driven vacuum braking device. Background technique [0002] Generally, a gasoline engine can generate a higher vacuum pressure in the intake manifold, but a vacuum pump must be installed in a diesel engine and a gasoline direct injection engine to provide a vacuum source to meet the requirements of the vacuum booster braking system. The brake system that uses hydraulic pressure as the transmission medium needs a booster system to assist the driver in braking. The vacuum brake booster system is based on the human hydraulic brake with a set of booster devices that provide braking force from other energy sources, so that It can be used together with power to improve the braking effect. [0003] At present, there are mainly two driving modes for the vacuum pump of an internal combustion engine vehicle. One is that the vacuum pump is installed on the engine gear cha...
