Description

A kind of acoustic filter and the motorcycle using the acoustic filter

Technical field

This utility model is related to technical field of motorcycles, in particular to a kind of acoustic filter and using the acoustic filter Motorcycle.

Background technology

In motorcycle engine structure, a large amount of machine oil can be injected in its crankcase, form oil sump to ensure lubricating system Requirement.This structure can make gas expansion in crankcase, pressure liter when electromotor works because organism temperature is drastically raised It is high.To ensure the balance of crankcase pressure, can breather be housed to discharge gas on its crankcase.Expellant gas are exactly bent Axle box waste gas.Containing moisture and machine oil in crankcase waste gas.To avoid polluting environment, national environmental protection rules and regulations crankcase waste gas Must not be directly discharged in air.The general method for processing crankcase waste gas is conducted in admission air silencer, with fresh air The burning of catalyst is participated in after mixing and crankcase waste gas is processed, the complex structure of existing acoustic filter, it is difficult to will be above-mentioned Waste gas burns completely, also causes the potential hazard of environmental pollution.

On the other hand, can also if being discharged in air between the tail gas for having started to be produced during operation of motorcycle Produce larger noise.In order to reduce noise, it is necessary to install acoustic filter in the gas extraction system of motorcycle.But use at present Acoustic filter there is a problem of complex structure, relatively costly.For example：Manifold and dividing plate are provided with acoustic filter, it is such to disappear Sound device complex structure, is difficult to repair, if break down whole acoustic filter can only be scrapped into process.Meanwhile, acoustic filter will also undertake Above-mentioned vent gas treatment work, even more increases the structural burden of acoustic filter.

Utility model content

The purpose of this utility model is to provide a kind of acoustic filter, and it can lift erasure effect.

Another object of the present utility model is to provide a kind of motorcycle, and it can install above-mentioned acoustic filter.

What embodiment of the present utility model was realized in：

A kind of acoustic filter, it includes air inlet pipe, silencing pot, escape pipe and the first outer housing.First outer housing is sheathed on noise elimination Cylinder.The both ends of silencing pot have the air inlet and gas outlet being oppositely arranged.Air inlet pipe is connected by air inlet with silencing pot, Silencing pot is connected by gas outlet with escape pipe.The inside of silencing pot has been arranged side by side multiple noise elimination bowls, and noise elimination bowl is provided with logical QI KOU.The axis for stating blow vent of two adjacent noise elimination bowls is not overlapped.This acoustic filter is suitable to install the gas extraction system of motorcycle, Erasure effect can be greatly improved.

A kind of motorcycle, it includes above-mentioned acoustic filter.

The beneficial effect of this utility model embodiment is：This utility model simple structure, convenient disassembly, be easy to repair etc. spy Point.By arranging multiple noise elimination bowls in silencing pot, on the one hand, without the need for setting manifold and other exhaustors in silencing pot again Road；On the other hand, more expansion chambers are defined between multiple noise elimination bowls, greatly improves erasure effect.
