Automobile exhaust system is typically by exhaustor, acoustic filter, catalyst and gas extraction system mounting parts etc.
Composition.Gas extraction system is mainly responsible for the processing controls after car load discharge, so that car load is discharged and meets concerned countries, local regulation.
Meanwhile, gas extraction system is also responsible for car load discharge back pressure, noise control critical function.Exhaust system muffler, main effect
Exactly control car load displacement noise.
For the electromotor of larger displacement, muffler volume accordingly must design larger, generally using circular, oval section
The acoustic filter of face shape.It is contemplated that road clearance and chassis space in the arrangement of actual car load chassis, it is designed as oval cutting
The acoustic filter in face is more suitable.Because muffler volume is larger, if the acoustic filter of elliptic cross-section is designed as a cavity, whole
Individual cavity is larger due to volume, and rigidity and resistant to bending intensity will be not enough, travel certain mileage in vehicle, may be relatively easy to send out
The problems such as give birth to middle part torsional fracture and crack.
Content of the invention
It is an object of the invention to provide a kind of automobile exhaust system acoustic filter is so as to acoustic filter can preferably be ensured
Integral rigidity and intensity, thus be not susceptible to quality problems.
To achieve these goals, the invention provides a kind of automobile exhaust system acoustic filter, including:
Inlet flange;
The first order acoustic filter being connected with described inlet flange;
The second level acoustic filter being connected with described first order acoustic filter by connecting tube;
Described second level acoustic filter connects a muffler tail pipe;
It is also associated with support between described first order acoustic filter and described second level acoustic filter.
Wherein, described support is V-shaped rest.
Wherein, one end of described support and described first order acoustic filter welding, the other end and the weldering of described second level acoustic filter
Connect.
Wherein, the entrance face of described first order acoustic filter is open end, and the breech face of described second level acoustic filter is
Open end.
Wherein, the axle of the breech face opening of the entrance face opening of described first order acoustic filter and described second level acoustic filter
Heart axis is identical.
Wherein, described support is located at the entrance face opening of described first order acoustic filter and the tail of described second level acoustic filter
On the axis of end face opening;
Described connecting tube is connected to the entrance face opening of described first order acoustic filter and the tail of described second level acoustic filter
The position of the non-axis of end face opening.
Wherein, described connecting tube is straight tube.
The present invention also provides a kind of automobile, including automobile exhaust system acoustic filter as above.
The technique scheme of the present invention at least has the advantages that:
The present invention passes through to consider actual car load chassis road clearance and chassis space, and automobile exhaust system acoustic filter is set
It is calculated as ellipse, thus being more suitable for the electromotor of larger displacement, or the very high small displacement engine of criteria of noise control is made an uproar
Sound post processing;Because muffler volume is larger, by being designed to two-stage type, a cavity is split up into two cavitys, its
Middle part, using certain reinforcement stiffness structure, preferably ensure that integral rigidity and the intensity of automobile exhaust system acoustic filter, from
And it is not susceptible to middle part torsional fracture and the problems such as crack;By the centre between first order acoustic filter and second level acoustic filter is connected
Pipe designs the non-axial location in first order acoustic filter open end opening and second level acoustic filter breech face opening, thus more preferably
Serve the design of acoustic filter internal noise relief features.

Specific embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing and tool
Body embodiment is described in detail.
One embodiment of the invention provides a kind of two-stage type automobile exhaust system acoustic filter, by a cavity of acoustic filter
It is split up into two cavitys, thus being more suitable for the electromotor of larger displacement, or the very high small displacement of criteria of noise control starts
Machine noise post processing;Middle part, using certain reinforcement stiffness structure, can better ensure that integral rigidity and the intensity of acoustic filter,
Thus being not susceptible to quality problems.
As shown in figure 1, the automobile exhaust system acoustic filter of the present invention includes inlet flange 1;It is connected with described inlet flange 1
First order acoustic filter 2;The second level acoustic filter 4 being connected with described first order acoustic filter 2 by connecting tube 3;The described second level
Acoustic filter 4 connects a muffler tail pipe 5;It is also associated with support between described first order acoustic filter 2 and described second level acoustic filter 4
6.
As shown in Fig. 2 the entrance face of described first order acoustic filter 2 is open end, at this opening, it is designed with acoustic filter
Inlet flange 1 and connecting tube, for connecting the pipeline of gas extraction system leading portion.
