Abstract
The utility model belongs to an electric vacuum pump's double suction gas vent posterior lateral plate, including posterior lateral plate body (1), be equipped with two curved positioning groove (5) and four bolt mounting holes (2) on the circumference of posterior lateral plate body (1), its characterized in that is equipped with a pair of induction port (3) and a pair of gas vent (4) symmetrically on posterior lateral plate body (1). The utility model discloses a realized breathing in for twice and twice exhaust, improved and inhaled carminative speed, solved the slow problem of brake reaction rate, improved the security performance that the automobile went.
Description
Technical field
This utility model belongs to the parts of electric vacuum pump, particularly to the double suction air vent back side panel of the brake assisted electric vacuum pump used on a kind of electric automobile.
Background technology
At present, in order to solve the problem of energy crisis and environmental pollution, the development of electric automobile has been built consensus in countries in the world, but due to technical restriction, the research and development of electric automobile are usually and improve on existing internal-combustion engines vehicle by China.Most cars use vacuum servo servosystem, make people and power and use.The vacuum source of the brakes vacuum booster unit of traditional combustion engine car is from motor intake manifold, and negative pressure of vacuum typically can reach 0.05-0.07MPa.For the electric motor car repacked into by orthodox car, after engine assembly is removed, brakes is not owing to having vacuum power source to lose vacuum servo function, and the brake force only produced by manpower cannot meet the needs of service brake；So electric vacuum pump to be installed realizes vacuum servo.Former vacuum pump design air entry is one, air vent one, and single-acting works, such air-breathing underspeed, and power-assisted response speed is slow, there is brake hidden danger.
Summary of the invention
It is an object of the invention to overcome above-mentioned technical deficiency, it is provided that a kind of double suction QI KOU, the double suction air vent back side panel of the electric vacuum pump that double-exhaust port works simultaneously.
This utility model solves technical problem and be the technical scheme is that the double suction air vent back side panel of a kind of electric vacuum pump, including back side panel body, is provided with the detent of two arcs and four bolt mounting holes on the circumference of back side panel body；It is characterized in that on back side panel body, be provided with a pair air entry and a pair air vent symmetrically.
The beneficial effects of the utility model are: this utility model achieves twice air-breathing and twice aerofluxus, improves the speed of suction and discharge, solve the problem that brake response speed is slow, improve the security performance of running car.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, illustrate with embodiment.
Fig. 1 is the main body figure of the double suction air vent back side panel of electric vacuum pump.
In figure: 1-back side panel body；2-bolt mounting holes；3-suction hole；4-air vent；5-detent；6-axis hole.
Detailed description of the invention
Embodiment, referring to the drawings, the double suction air vent back side panel of a kind of electric vacuum pump, including back side panel body 1, the circumference of back side panel body 1 is provided with the detent 5 of two arcs and four bolt mounting holes 2；It is characterized in that on back side panel body 1, be provided with a pair air entry 3 and a pair air vent 4 symmetrically.
Back side panel body 1 center is provided with axis hole 6.
Pump often revolves goes around, it is achieved that twice suction, aerofluxus, and suction and discharge speed is doubled, and solves the problem that brake speed is slow, improves the security performance in running car.
Claims (1)
1. a double suction air vent back side panel for electric vacuum pump, including back side panel body (1), is provided with the detent (5) of two arcs and four bolt mounting holes (2) on the circumference of back side panel body (1)；It is characterized in that on back side panel body (1), be provided with a pair air entry (3) and a pair air vent (4) symmetrically.
