Abstract
The utility model relates to a direct-current electron vacuum pump of an automobile braking system, belonging to the technical field of automobile braking systems. The direct-current electron vacuum pump is composed of a housing, an upper end cover, a pump body, a lower end cover, a direct-current electrical motor, an impeller and doctor blades, wherein the direct-current electric motor is fixedly connected with the pump body through a junction box; the left and the right sides of the pump body are provided with the upper end cover and the lower end cover; the upper end cover is provided with a vacuum booster gas receiving port; the pump body is provided with an exhaust port; one side of the upper end of the pump body is provided with the housing; the pump body is internally provided with the impeller eccentrically; and the impeller is provided with the doctor blades. According to the direct-current electron vacuum pump, a five-groove uniformly distributed structure is adopted on the impeller, the five doctor blades are arranged in five grooves in a floating manner, and the volumes of the cavities of the doctor blades become smaller during the process that the impeller rotates a circle under the effect of a centrifugal force so as to form three processes of air suction, compression and air exhaust, so that the vacuumizing effect of a vacuum booster is achieved. The vacuumizing problems of the existing turbine boosting automobiles, plug-in hybrid automobiles and purely electric automobiles are solved.
Description
Technical field
The utility model relates to a kind of brake system of car DC electronic vacuum pump for turbosupercharging automobile, plug-in hybrid-power automobile, pure electric automobile braking, belongs to the brake system of car technical field.
Background technique
The brake vacuum source of existing passenger car braking system is mainly from engine intake manifold, when motor is air-breathing, form vacuum in intake manifold, because vacuum booster links to each other with engine intake manifold by pipeline, realize the function that vacuum booster is vacuumized; When the driver stepped on brake petal, atmospheric pressure acted on vacuum booster one side, plays the power brake effect.But it is just different on turbosupercharging automobile, hybrid vehicle and electric vehicle, the turbosupercharging automobile is owing to adopt turbocharging technology, the plenum system of engine intake manifold is under the turbosupercharger effect, what adopt is the malleation plenum system, can not vacuumize vacuum booster again, at this moment need to have special vacuumizing part to finish.Hybrid vehicle, electric vehicle also must have special vacuum pumping device that vacuum source is provided because adopting motor driving.
Summary of the invention
The purpose of this utility model is, providing a kind of is power supply with the on-vehicle battery, rotate by the driven by motor impeller, in the process that impeller rotates a circle, cavity volume changes from large to small, formation is bled, compression, three processes of exhaust vacuumize vacuum booster, realizes turbosupercharging automobile, plug-in hybrid-power automobile, pure electric automobile are played when the braking brake system of car DC electronic vacuum pump of power brake effect.
The utility model is to realize above-mentioned purpose by the following technical solutions:
This brake system of car DC electronic vacuum pump is made of case, upper end cap, the pump housing, lower end cap, direct current generator, impeller, coupling and scraping blade, it is characterized in that: direct current generator be connected with the pump housing by coupling and by bolt tightening on the pump housing, the left and right sides of the pump housing is equipped with upper end cap and lower end cap respectively, upper end cap and lower end cap are fixed tightly on the pump housing by connecting screw rod, are manufactured with vacuum booster on the upper end cap and connect gas port; Be manufactured with relief opening on the pump housing, upper end cap one side of the pump housing is equipped with case; Be off-centre with the pump housing in the described pump housing inner chamber impeller is installed, be manufactured with 5 chutes on the impeller, scraping blade is installed in the chute.
The utility model beneficial effect compared with prior art is:
Adopt 5 groove distribution equalizing structures on the impeller of this brake system of car DC electronic vacuum pump, 5 scraping blades float and are installed in 5 grooves of impeller, under action of centrifugal force, scraping blade is relative movement in groove, impeller, squeegee material adopt carbon material to realize dry type selflubricating mode, need not oil lubrication, and can adopt the DC12V direct current generator to drive.Solved the problem that existing turbosupercharging automobile, plug-in hybrid-power automobile, pure electric automobile vacuumize.
