A kind of vehicle, electromotor and air filter thereof
Technical field
This utility model relates to technical field of vehicle, particularly to a kind of air filter.This utility model further relates to a kind of tool
There is the electromotor of this air filter.In addition, this utility model further relates to a kind of vehicle with above-mentioned electromotor.
Background technology
Vehicle motor is the most accurate parts, and minimum impurity all can damage electromotor.Therefore, air is entering gas
Before cylinder, it is necessary to first pass through the fine and closely woven filtration of air filter, the cylinder of electromotor could be entered.Air filter includes filter element
And housing, all there is a pipeline before and after air filter, air is introduced air filter and is filtered by front end pipeline, after air filter
End pipeline is that the air introduction electromotor after filtering burns.
In addition, turbocharger as a kind of efficient, energy-conservation environmentally friendly machine, is improved automobile send out owing to it is had
Motivation pollution emission, the power improving electromotor and weight ratio, the torque characteristics of raising electromotor, reduction fuel oil consumption etc.
Advantage so that turbocharger is widely used in automobile industry.
The compressor aerodynamic noise that turbocharger produces is propagated and spoke to air inlet by air inlet pipe and air filter
Penetrating, owing to compressor aerodynamic noise has broadband character, air filter itself can not meet reduction intake system noise
Requirement, the noise reduction measure of present wide variety of automobile air inlet system mainly layout Helmholtz acoustic filter and several four points
One of wavelength tube, but they are the noises eliminating some mid frequency targetedly, and frequency band is narrower, it is impossible to eliminate wideband and make an uproar
Sound, therefore, the air inlet broadband muffler that design soundproof effect is good is the important way controlling engine with supercharger induction noise
Footpath.
The most wide variety of intake muffler is quarter-wave long tube and Helmholtz acoustic filter, but they
Being the noise eliminating some mid frequency targetedly, frequency band is narrower, usually solves the noise problem under different frequency,
Need several quarter-wave long tubes or Helmholtz acoustic filter.Market upper air system uses broadband muffler to be fewer
See, and air filter and broadband muffler are two self-existent individualities, are respectively completed the filtration to air and reduction
The function of wideband induction noise.Gas handling system uses broadband muffler to be that comparison is rare in the market, and air filter
It is two self-existent individualities with broadband muffler, is respectively completed the filtration to air and reduces the merit of wideband induction noise
Energy.Acoustic filter, as an independent individual, occupies larger space in gas handling system, and needs it by certain type of attachment
It is connected in gas handling system, virtually adds systematic part kind, increase various cost.
