Abstract
The invention relates to an automobile electric vacuum pump, and belongs to the field of automobile brake. An air filter is mounted on an upper shell body. An impeller is mounted between the upper shell body and a lower shell body. Motors are mounted on the bottom of the lower shell and are connected with the impeller through a gear set. A protective cover is installed on the outer portion of the gear set. A machine body air outlet is placed between the upper shell body and the lower shell body, a vacuum generator is connected with the machine body air outlet, and the vacuum generator is provided with a vacuum connector. A silencer is connected with an outlet of the vacuum generator. The automobile electric vacuum pump has the advantages of being novel in structure, effectively overcoming the existing defects, better obtaining a rapid, efficient, stable and low-noise vacuum source, improving the safety, reliability and comfort of an automobile, and solving the problem of the vacuum source in an electric automobile braking system.
Description
Technical field
The invention belongs to the automobile brake field, refer in particular to the new-energy automobile electric vacuum pump.
Background technique
Electric vacuum pump of automobile is critical component in the new-energy automobile braking system.Its working principle is to use individual motor or vehicle power source drives impeller blower fan, the high velocity air Rapid Flow that utilizes blower fan to produce is crossed vacuum generator, nozzle in vacuum generator inside forms jet air, the generation air-flow entrainments, under the effect of entrainmenting, the air of spout periphery is sucked away, and can produce fast parital vacuum.Vacuum position is drawn by vacuum connect, be connected to automobile vacuum booster.Brake system of car electric vacuum pump in the past uses the motion structures such as diaphragm, vane, piston, and the generation negative pressure deflates from cavity volume.There are the deficiencys such as energy consumption is high, vacuum is built and pressed slowly, and the friction noise between mechanical parts is very large in these working methods.
Summary of the invention
The invention provides a kind of electric vacuum pump of automobile, use diaphragm, vane, piston to solve existing brake system of car electric vacuum pump, the generation negative pressure that from cavity volume, deflates, energy consumption is high, vacuum is built and pressed slowly the problem that the friction noise between mechanical parts is large.
Technological scheme of the present invention is: air filter is installed on the upper shell, impeller is installed between upper shell and the lower shell body, motor is installed in the lower shell body bottom, motor is connected with impeller by gear train, protective housing is installed in the gear train outside, and the body exhaust outlet is between upper shell, lower shell body, and vacuum generator is connected with the body exhaust outlet, be provided with vacuum connect on the vacuum generator, baffler is connected with the outlet of vacuum generator.
The invention has the advantages that: novel structure, efficiently solve existing deficiency, better realized vacuum source quick, efficient, stable, low noise, improved Security, reliability and the travelling comfort of vehicle, solved vacuum source in the braking system of electric car.
Description of drawings
Fig. 1 is explosive view of the present invention;
Fig. 2 is the sectional view of vacuum generator of the present invention;
Among the figure, air filter 1, upper shell 2, impeller 3, lower shell body 4, protective housing 5, gear train 6, motor 7, baffler 8, vacuum generator 9, body exhaust outlet 10, vacuum connect 11.
Embodiment
Air filter 1 is installed on the upper shell 2, impeller 3 is installed between upper shell 2 and the lower shell body 4, motor 7 is installed in lower shell body 4 bottoms, motor 7 is connected with impeller 3 by gear train 6, protective housing 5 is installed in gear train 6 outsides, and body exhaust outlet 10 is between upper shell 2, lower shell body 4, and vacuum generator 9 is connected with body exhaust outlet 10, be provided with vacuum connect 11 on the vacuum generator 9, baffler 8 is connected with the outlet of vacuum generator 9.
Different from the common electric vacuum pump is that automobile brake booster of the present invention uses blower fan as the malleation wind regime, utilizes vacuum generator to produce vacuum.Air enters body by air filter, the impurity such as dust in the air filter filtered air, in the body of upper shell and lower shell body composition, impeller accelerates air and enters vacuum generator from the discharge of body exhaust outlet, air also is sucked away at the air of vacuum generator inwall, thereby produces vacuum at the vacuum connect place at a high speed when the vacuum generator, the vacuum generator afterbody is installed baffler, filters the wind of high velocity air generation and makes an uproar.
