Assembling structure of silencer

Abstract

The invention relates to an assembling structure of a silencer. The assembling structure comprises a silencer main body and a connecting pipe, whrein a tail pipe at one end of the silencer main body is connected with the connecting pipe through a first exhaust funnel hoop; and the assembling structure is characterized in that a plurality of first limiting bosses are arranged at the end of the tailpipe at one end of the silencer main body, a plurality of corresponding second limiting bosses are arranged at the connecting end of the connecting pipe and the tail pipe of the silencer main body, and the first limiting bosses and the second limiting bosses are matched to limit the length of the section, inserted into the silencer body, of the connecting pipe; and positioning gaps are formed between every two adjacent first limiting bosses, positioning pin bodies matched with the corresponding positioning gaps are arranged on the connecting pipe, and when the silencer main body is assembledwith the connecting pipe, the positioning pin bodies and the corresponding positioning gaps are matched to limit the relative position of the connecting pipe and the silencer main body. According to the assembling structure, the assembling process of the silencer and the connecting pipe can be effectively controlled, and the assembling process of the silencer can be effectively controlled..

Description

technical field [0001] The invention relates to a muffler, in particular to an assembly structure of the muffler, and belongs to the technical field of engine assembly. Background technique [0002] The muffler is an important part of the engine, and there are various installation methods for the muffler. At present, in most cases, the muffler adopts the ordinary plug-in scheme, and the outlet pipe of the muffler and the tail pipe or connecting pipe are fixed by a clamp; however, in actual assembly, it is greatly affected by manual assembly factors, which makes it difficult to control the length of the tail pipe inserted into the muffler; And it is prone to shaking after working for a long time. In addition, the temperature of the outer surface of the muffler is high, the heat radiation is very high, and there are relatively high requirements for the space, distance, and heat protection of adjacent parts, which makes the layout of the muffler even more difficult.

At present, in most cases, the muffler adopts the ordinary plug-in scheme, and the outlet pipe of the muffler and the tail pipe or connecting pipe are fixed by a clamp; however, in actual assembly, it is greatly affected by manual assembly factors, which makes it difficult to control the length of the tail pipe inserted into the muffler; And it is easy to shake after working for a long time

In addition, the temperature of the outer surface of the muffler is high, the heat radiation is very high, and there are relatively high requirements for the space, distance, and thermal protection of adjacent parts, which makes the layout of the muffler even more difficult.
