Abstract
The utility model discloses an electric power brake auxiliary system of an electric vehicle, comprising an electric vehicle auxiliary power supply, a vacuum pump and a brake vacuum booster, wherein the electric power brake auxiliary system of the electric vehicle also comprises a vacuum gas storage tank; the brake vacuum booster is connected to the vacuum gas storage tank by a vacuum pipeline and is then connected with the vacuum pump by the vacuum pipeline; the vacuum gas storage tank is provided with a vacuum pressure detector which is connected with a vacuum pump delay control switch; and the vacuum pump delay control switch is connected with the electric vehicle auxiliary power supply and the vacuum pump by circuits. The electric power brake auxiliary system detects the vacuum pressure in the vacuum gas storage tank by the vacuum pressure detector, when the pressure of the vacuum gas storage tank is lower than a set value, the electric vacuum pump power supply is not cut off immediately, while the vacuum pump delays the work to the set time continuously so as to lead the pressure in the vacuum gas storage tank to be reduced continuously, thus maintaining the stability of the pressure in the vacuum gas storage tank and guaranteeing the vacuum boosting efficiency when in braking at any time.
Description
Technical field
The utility model relates to a kind of braking automobile auxiliary device, relates in particular to a kind of electric boosted BAS that is used for electronlmobil.
Background technology
Generally all be provided with especially vacuum brake power-assisted of brake power-assisted at present on the automobile, in fuel-engined vehicle, the degree of vacuum of induction maniflod is to guarantee the brake power-assisted when mainly relying on engine operation, but in electronlmobil, generally all be to vacuumize by an electric vacuum pump, in order to keep degree of vacuum to guarantee brake power-assisted usefulness, the work that needs vacuum pump always not stop, power consumption is too big like this, and noise is also big, simultaneously the vacuum pump work of not stopping work, the possibility of et out of order is also higher, in case vacuum pump et out of order like this, the brake force aid system does not have vacuum source, and consequence is hardly imaginable.
The utility model content
Problem to be solved in the utility model provides a kind of electric power assisting brake auxiliary system of electric car that keeps vacustat, vacuum pump intermittent use, energy-conserving and environment-protective.
The technical scheme that the utility model adopted is: electric power assisting brake auxiliary system of electric car, comprise the electronlmobil accessory feed, vacuum pump, the brake vacuum assist device, described electric power assisting brake auxiliary system of electric car also comprises vacuum air storage tank, described brake vacuum assist device is connected to vacuum air storage tank by vacuum line and is connected to vacuum pump by vacuum line again, described vacuum air storage tank is provided with the vacuum-pressure detection device, described vacuum-pressure detection device is connected with a vacuum pump delay control switch, described vacuum pump delay control switch and electronlmobil accessory feed, the vacuum pump circuit connects.
In the such scheme, described vacuum pump delay control switch is a slug relay.
In the such scheme, described vacuum-pressure detection device is pressure switch or pressure sensor, and pressure control range is 20kpa～40kpa.
The beneficial effects of the utility model are: the utility model detects vacuum pressure in the vacuum air storage tank by the vacuum-pressure detection device, when its pressure is higher than setting value for example during 40kpa, connect the vacuum pump delay control switch, make vacuum pump work, the vacuum-pressure detection device detects the pressure in the vacuum air storage tank simultaneously.When vacuum storage tank internal pressure is lower than setting value for example during 40kpa, delay control switch does not cut off the Motorized vacuum pumping source immediately, but make vacuum pump continue delay working to the time of setting, make the vacuum air storage tank internal pressure continue to reduce, after the setting-up time timing arrives, vacuum pump just quits work, at this moment the pressure in the vacuum air storage tank will be reduced to about 20kpa, pressure in the vacuum air storage tank will be remained between 20kpa～40kpa, keep the stable of vacuum air storage tank internal pressure, guaranteed the vacuum servo usefulness the when marquis brakes when any, avoided the vacuum pump frequent starting, make the vacuum pump intermittent use, prolong its service life, reduced rate of breakdown, energy-conserving and environment-protective simultaneously, and reduced the expenditure of energy of electronlmobil accessory feed, improved the driving range of electronlmobil.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the structural representation of the utility model specific embodiment;
