Shared silencing bag device

Abstract

The invention discloses a shared silencing bag device that comprises a silencing bag body, wherein the silencing bag body is a box body; the silencing bag body comprises an upper shell and a lower shell; the bottom edges of the upper shell and the lower shell are provided with flanges; the upper shell and the lower shell are fixedly connected through the flanges; an air outlet is commonly formed in the right end of the upper shell and the right end of the lower shell, an air inlet is commonly formed in the included angle of the lower side edges of the left ends of the upper shell and the lowershell, the air inlet is communicated with a front exhaust system, the air outlet is communicated with a rear exhaust system, and the silencing bag body is fixed below an automobile floor. The sharedsilencing bag device can be arranged in an up / down overturning mode; a transverse arrangement mode, a longitudinal arrangement mode and other arrangement modes are adopted, thus reducing the arrangement space and pipeline directions, and reducing technical limitations of parameters of a whole vehicle on the exhaust system; the universality of the silencing bag body is effectively improved.

Description

technical field [0001] The invention relates to a shared type noise-absorbing bag device, in particular to a shared-type sound-absorbing bag device which can be used alternately up and down. Background technique [0002] The exhaust system is connected to the exhaust end of the engine, and its main function is to discharge engine exhaust and reduce noise. The exhaust system extends from the front of the engine compartment to the rear of the vehicle. The total length of the system is close to the length of the entire vehicle. Its boundary covers many parts under the chassis, so the layout space is greatly limited. Due to the limitation of the layout space, the exhaust system and its muffler, The generality of the layout scheme of the noise reduction package is poor. Different models adopt different design schemes, which makes it difficult to implement the platform, and at the same time leads to an increase in development costs. The air inlet and outlet of the conventional noi...

Problems solved by technology

The exhaust system extends from the front of the engine compartment to the rear of the vehicle. The total length of the system is close to the length of the entire vehicle. Its boundary covers many parts under the chassis, so the layout space is greatly limited. Due to the limitation of the layout space, the exhaust system and its muffler, The generality of the layout scheme of the noise reduction package is poor. Different models adopt different design schemes, which makes it difficult to implement the platform, and at the same time leads to an increase in development costs. The air inlet and outlet of the conventional noise reduction package are generally arranged in parallel. The following cannot be used interchangeably, thus resulting in a lack of commonality
