Abstract
The utility model relates to a brake assisting system of an electric car. The brake assisting system comprises a brake pedal which is connected with a vacuum assisting device. The vacuum assisting device is connected with a brake main pump, and is connected with a vacuum pump through a pipeline. The vacuum assisting device, the vacuum pump and the brake main pump are connected with a gas storage tank through pipelines. A pressure sensor is arranged on the pipeline. The brake assisting system of the electric car can effectively reduce work load of the vacuum pump, avoids futile work, saves energy resource, reduces noise, and prolongs service life of all components.
Description
Technical field
The utility model relates to a kind of electric vehicle brake force aid system.
Background technology
Electronlmobil refers to travel with power wheel take vehicle power as power, meets the vehicle of arteries of communication, legislative control on safety requirements.The waste gas that produces when electronlmobil is worked without internal-combustion engines vehicle does not produce exhaust pollution, is very useful to the cleaning of environmental protection and air, almost is " zero pollutes ", and its prospect is extensively had an optimistic view of, but current techniques is still immature.The principle of vacuum brake power-assisted is that the negative pressure and the difference of pressure between the barometric pressure that produce when utilizing engine operation produce the effect of brake power-assisted, to alleviate the power that imposes on brake pedal.Existing vacuum boost system is realized the brake power-assisted by not stop pumping of vacuum pump vacuum, but power consumption is too large, and time is everlasting when reaching maximum vacuum, and vacuum pump still continues to flog a dead horse, and causes unnecessary waste.
The utility model content
The purpose of this utility model is to provide a kind of can reduce energy dissipation, reduces the electric vehicle brake force aid system of parts loss.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of electric vehicle brake force aid system, comprise brake pedal, described brake pedal is connected with vacuum booster unit, described vacuum booster unit connects master brake cylinder and is connected with vacuum pump by pipeline, and described vacuum booster unit, vacuum pump and master brake cylinder are connected pipeline and are connected with storage tank.
Described pipeline is provided with pressure sensor.
Because the employing of technique scheme, the utility model compared with prior art has the following advantages: the utility model can effectively reduce the vacuum pump work load, avoids flogging a dead horse, and has saved the energy, has reduced noise, has improved each parts service life.
Description of drawings
Fig. 1 is the utility model structural representation;
Wherein: 1. vacuum booster unit; 2. vacuum pump; 3. storage tank; 4. pressure sensor; 5. brake pedal; 6. master brake cylinder.
The specific embodiment
As shown in Figure 1, this system comprises brake pedal 5, described brake pedal 5 is connected with vacuum booster unit 1, described vacuum booster unit 1 connects master brake cylinder 6 and is connected with vacuum pump 2 by pipeline, and described vacuum booster unit 1, vacuum pump 2 are connected with master brake cylinder and are connected with storage tank 3 by pipeline.Described pipeline is provided with pressure sensor 4.
During vehicle operation, degree of vacuum in pressure sensor 4 checking systems when degree of vacuum is lower than setting value, starts vacuum pump 2 by controller and starts working.When degree of vacuum was higher than setting value, controller control vacuum pump 2 quit work.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
