Description
Technical field
This utility model is related to technical field of automobile parts, more particularly to a kind of vacuum pump noise reduction set.
Background technology
As petroleum resources are reduced increasingly, Abgasgesetz is increasingly strict, and energy-saving and emission-reduction have become the pass of Automobile Design consideration
Key factor.Traditional mechanical formula vacuum pump power consumption is big, and noise rings, and the continuous firing ability in engine operation process,
Current energy consumption of vehicles demand can not have been met, meanwhile, the development of pure electric vehicle needs one kind not rely on and starts motor-driven
Power, and the device of vacuum needed for braking can be provided in good time, such as electric vacuum pump, and the Unique physical design of electric vacuum pump,
A kind of new noise reduction set is needed to coordinate.
The content of the invention
The purpose of this utility model is to solve above-mentioned technical problem, there is provided a kind of simple structure, long service life, body
Product is little, and noise is little, is suitable to the vacuum pump noise reduction set that electric vehicle electric vacuum pump is used.
To achieve these goals, this utility model adopts the following technical scheme that a kind of vacuum pump noise reduction set, sound insulation lid is consolidated
It is scheduled on vacuum pump frame, noise reduction set, aerofluxuss disk, stator, suction disk, sealing is sequentially provided between sound insulation lid and vacuum pump frame
Circle, described noise reduction set is tray type structure, and the noise reduction is arranged with first flange, second flange, the 3rd flange, described first
Flange is with sound insulation cap-shaped into the first surge chamber, and the first flange, second flange and sound insulation cap-shaped are described into the second surge chamber
3rd flange forms front buffer room with aerofluxuss disk, and the noise reduction set middle part is provided with exhaust hole, described exhaust hole connection
First surge chamber and front buffer room.In this programme, gas is entered from pedestal air inlet and is transported to by suction disk, stator, row
Gas armor into electric vacuum pump working chamber in, be then discharged in working chamber and by aerofluxuss disk and noise reduction set between
Front buffer room, then covers into sound insulation lid and the first surge chamber to be formed buffering is covered with noise reduction, subsequently into sound insulation by noise reduction
Lid covers the second surge chamber to be formed buffering with noise reduction, enters back into pedestal air vent, and gas is discharged from air vent, realizes the list of gas
To motion, so, vacuum can be formed at carrier (vehicle) position connected with air-inlet of vacuum pump；Noise reduction set plays isolation air-flow
Passage, expands the effect in air-flow buffer space.
Preferably, described noise reduction set is provided with the annular for covering sunken inside to noise reduction near the one side of sound insulation lid holds air drain.
The annular of this programme holds air drain and is located at the first buffering chamber region, can be used to increase the volume of the first surge chamber, increases gas buffer
Effect.
Preferably, described noise reduction set is provided with the annular improving inspiration by invigorating kidney-QI groove that sunken inside is covered to noise reduction near the one side of aerofluxuss disk.
The annular improving inspiration by invigorating kidney-QI groove of this programme is located at front buffer chamber region, can be used to increase the volume of front buffer room, increases gas buffer
Effect.
The beneficial effect of this programme is：1) impact load and noise in pump housing operation process is alleviated；2) air-flow is isolated
Passage, expands air-flow buffer space；3) this programme small volume, installs and safeguards more easy.
