Abstract
The invention relates to an electronic-braking vacuum pump of an electric vehicle. The electronic-braking vacuum pump comprises a pump body (1) and a motor shell (10). A pump stator (8) is mounted in a cavity of the pump body (1). A pump rotor (7) is mounted at the center of the pump stator (8). A motor stator (9) is mounted in a cavity of the motor shell (10). A motor rotor (11) is mounted at the center of the motor stator (9). A pump blade (6) is mounted on the pump rotor (7). The electronic-braking vacuum pump is characterized in that four blade grooves (6-1) are evenly formed in the pump blade (6) and are respectively perpendicular to the vertical center line (6-2) and the horizontal center line (6-3). The electronic-braking vacuum pump is good in vacuum performance and high in strength, not easy to break and low in noise during operation.
Description
Technical field
The invention belongs to brake vacuum pump, particularly a kind of electronlmobil deceleration of electrons vacuum pump.
Background technology
At present, in order to solve the problem of energy shock and environmental pollution, the development of electronlmobil is built consensus in countries in the world, but due to technical restriction, China is generally to improve on existing internal-combustion engines vehicle to the research and development of electronlmobil.Most cars adopt vacuum servo Fu, make people and power and use.The vacuum source of the brake system vacuum booster unit of traditional combustion engine car is from engine intake manifold, and negative pressure of vacuum generally can reach 0.05-0.07MPa.For the battery-driven car being repacked into by orthodox car, after engine assembly is removed, brake system is not owing to having vacuum power source to lose vacuum servo function, and the braking force only being produced by manpower cannot meet the needs of service brake; Existing deceleration of electrons vacuum pump, pump blade design is unreasonable, and the noise that gets into smooth is large, and vacuum performance is poor, and intensity is low, easy fracture.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide a kind of noise little, vacuum performance is good, and intensity is high, not the electronlmobil deceleration of electrons vacuum pump of easy fracture.
The technical scheme that technical solution problem of the present invention adopts is: a kind of electronlmobil deceleration of electrons vacuum pump, comprise the pump housing and electric machine casing, and in pump housing chamber, pump stator is housed, pump rotor is equipped with at pump stator center; Epipleural is equipped with in pump stator and pump rotor upper end, and lower side panel is equipped with in lower end; Motor casing body cavity is in-built motor stator, and rotor is equipped with at motor stator center, and rotor center is fixed with motor shaft; Motor shaft upper end is fixedly connected with pump rotor, and pump blade is housed on pump rotor, it is characterized in that being provided with uniformly four blade grooves on pump blade, and blade groove is respectively perpendicular to vertical center line and horizontal center line.
The invention has the beneficial effects as follows: this invention vacuum performance is good, and intensity is high, the easy fracture noise that gets into smooth is not low.

The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of electronlmobil deceleration of electrons vacuum pump, comprises the pump housing 1 and electric machine casing 10, in the pump housing 1 chamber, pump stator 8 is housed, pump rotor 7 is equipped with at pump stator 8 centers; Epipleural 3 is equipped with in pump stator 8 and pump rotor 7 upper ends, and lower side panel 2 is equipped with in lower end; Electric machine casing is equipped with motor stator 9 in 10 chambeies, and rotor 11 is equipped with at motor stator 9 centers, and rotor 11 centers are fixed with motor shaft 12; Motor shaft 12 upper ends are fixedly connected with pump rotor 7, and pump blade 6 is housed on pump rotor 7, it is characterized in that being provided with uniformly four blade groove 6-1 on pump blade 6, and blade groove 6-1 is respectively perpendicular to vertical center line 6-2 and horizontal center line 6-3.Electric machine casing 10 upper ends are connected with the pump housing 1, lower end dress motor cover 14, and circuit card 13 is equipped with in the interior bottom of electric machine casing 10, controls rotor 11 revolutions; The shaft of rotor 11 is connected with pump blade axle, and pump blade axle is fixedly connected with pump blade axis hole 6-4; Signal wire (SW) 15 is housed in motor cover 14, is communicated with circuit card 13; Pump cover 5 and aspirate tube 4 are equipped with in the pump housing 1 upper end.
Principle of work: pump stator 8 inner chambers are made ellipse, in the time that the motor shaft 12 in rotor 11 rotates, the pump blade 6 that drive is fixed on motor shaft 12 rotates, be contained in blade in blade groove 6-1 under the effect of centnifugal force, blade is pasting oval inwall and is getting rid of to outside direction, and due to oval eccentric action, the air inlet side of blade-type pump is different from the volume of exhaust side, air inlet side capacity increases, thereby exhaust side capacity reduces to produce degree of vacuum.This invention just can produce the vacuum source of enough pressure, is applied on electronlmobil.
