Description
Technical field
The utility model relates to brake system of car relevant device, relates to a kind of Vehicular electric vane pump specifically.
Background technique
New-energy automobile adopts motoring, eliminate traditional engine-driving, lose vacuum source, electric vacuum pump is given birth to make up this shortcoming, become the vacuum source that new-energy automobile is reliable and stable, in the braking system of new-energy automobile and hybrid vehicle, play vital effect.Nowadays, electronic vane pump is applied comparatively extensive in new-energy automobile technology.
The working method of traditional blades pump is that a motor rotor driven is with moving vane to do centrifugal motion then in stator, by reaching the effect of exhaust of bleeding to the compression of air.Vane pump compact structure, saves space, the dark welcome by electric vehicle developer.Simultaneously.Because vane pump only bears transverse force in the running, so bearing is longer for working life, not easily break down.
But when driver steps on brake petal continuously, in braking system, degree of vacuum reduces rapidly.If vane pump efficiency is not high enough, cannot bleed in time and make degree of vacuum in braking system be returned to optimum level, cannot obtain best assist rate, braking effect also can decrease, and may cause a series of unpredictable serious consequence.On the other hand, when emergency braking, driver steps on brake petal suddenly, if the reaction time of vane pump is long, or the pumping efficiency of vane pump is too low, the degree of vacuum in braking system can not be made to reach optimum level in the shortest time, thus best assist rate can not be obtained, braking effect is bad, also may cause a series of unpredictable serious consequence.
Model utility content
The purpose of this utility model is to provide a kind of novel Vehicular electric vane pump, to solve the low problem of existing new-energy automobile electricity consumption moving vane pump efficiency.
The purpose of this utility model is achieved in that
A kind of Vehicular electric vane pump, it is characterized in that, comprise: be arranged on the first motor on a binary electric motor end cap and the second motor, by shaft-driven first suction-exhaust mechanism of the output of the first motor, by shaft-driven second suction-exhaust mechanism of the output of the second motor, and to be fixed on described binary electric motor end cap and described first suction-exhaust mechanism and the second suction-exhaust mechanism to be carried out to the pump casing cover of capping;
Described first suction-exhaust mechanism comprises stator, the rotor assembly be arranged in stator, the locating cover that is arranged on the gland above stator and is arranged on below stator; Described rotor assembly is by rotor and be arranged at epitrochanterian blade and form; Described locating cover is provided with inlet hole, described gland is provided with exhaust port;
Described second suction-exhaust mechanism is identical with the structure of described first suction-exhaust mechanism;
Described binary electric motor end cap is integrated with air flue, and one end of described air flue is communicated with the inlet hole of described first suction-exhaust mechanism and the inlet hole of described second suction-exhaust mechanism respectively by two branch roads, and the other end of described air flue is external-connected port; Described pump casing cover is provided with vent, and described vent is connected with the exhaust port of described second suction-exhaust mechanism with the exhaust port of described first suction-exhaust mechanism.
Described Vehicular electric vane pump, described rotor is set for the eccentric relative to described stator.
Described Vehicular electric vane pump, motor output shaft drives described rotor assembly to rotate by shift fork.
The utility model is by being arranged on a binary electric motor end cap by two motors, and on this binary electric motor end cap an integrated air flue, while the Installation Flexibility that improve vane pump entirety, air flue integrated on end cap is bled by a suction port, shortens pumpdown time, increases rate of air sucked in required, it is the vacuum that braking system provides enough with timely, meet the requirement to degree of vacuum when braking continuously, keep the stability of the degree of vacuum in braking system, braking effect also can be stablized thereupon.
In addition, the utility model is because use two vane pumps, and substantially reduce the work load of individual blade pump, the temperature of such vane pump also can reduce, thus extends the working life of vane pump.Further, because increase electric motor end cap, so can be convenient with car body installation aspect, alleviate the workload of automobile assembling, saved manpower and materials.
