Hydraulic braking device and automobile with the same

Abstract

The invention discloses a hydraulic braking device and an automobile with the hydraulic braking device, and relates to the technical field of hydraulic braking. The hydraulic braking device comprises a footstep, a vacuum booster, a braking master pump, a vacuum supercharger unit and a vacuum tank, wherein the footstep, the vacuum booster and the braking master pump are sequentially connected, the vacuum supercharger unit is connected with the braking master pump, a left front wheel brake, a right front wheel brake, a left rear wheel brake and a right rear wheel brake through hydraulic pipelines, and the vacuum tank is connected with an engine vacuum source, the vacuum booster and the vacuum supercharger unit through vacuum pipelines. The hydraulic braking device solves the problem that a hydraulic disc brake motorcycle type is difficult in booster arrangement due to limited cab space and poor in braking force due to an poor boosting effect, according to the fact that the booster and the supercharger unit are used in a combined mode, a set of boosting system is combined, the effect that a braking system obtains enough assistant power is achieved, when the hydraulic braking device is in use, the footstep is light in feeling, and braking is sensitive in reaction.

Description

technical field [0001] The invention relates to the technical field of hydraulic braking, in particular to a hydraulic braking device and an automobile with the hydraulic braking device. Background technique [0002] The vacuum booster is a device that can effectively reduce the braking force, such as figure 1 As shown, the existing hydraulic braking device using a vacuum booster includes a pedal 1, a vacuum booster 2 and a brake master cylinder 3 connected in sequence; an engine vacuum source (vacuum pump) that provides a vacuum source for the vacuum booster 2 or intake manifold); the left front wheel brake, the right front wheel brake, the left rear wheel brake and the right rear wheel brake that are connected to the brake master cylinder 3 through the hydraulic pipeline. Its working process is as follows: stepping on the pedal 1 by manpower provides the initial input force for the vacuum booster 2 assembled in the cab, the engine vacuum source provides the vacuum source ...

AI Technical Summary

Problems solved by technology

[0003] The current commercial vehicles with hydraulic disc brakes, such as heavy transport vehicles, large cranes, excavators, bulldozers, road rollers, loading vehicles, electric emergency repair vehicles, engineering emergency vehicles, off-road engineering vehicles, electric welding engineering vehicles, armored engineering vehicles (combat engineering Vehicles) and oxidant sewage treatment engineering vehicles, etc., the braking system generally needs to use a large braking force to achieve braking, and in use, the pedals feel heavy and the braking response is lagging. inconvenience caused by personnel

[0004] At present, the commonly used method is to increase the vacuum booster to improve the boosting performance. However, due to the small space in the cab of the existing hydraulic disc brake commercial vehicles, it is difficult to arrange a larger size in the braking device due to the space limitation of the cab. Vacuum booster, so that the boosting effect cannot be achieved, which will eventually lead to poor braking effect, and emergency situations will also lead to traffic accidents
