Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] During specific implementation: if figure 1 with figure 2 As shown, a motorcycle muffler sealed and heat-insulated connection structure includes an engine 1 and a muffler 2, the exhaust port of the engine 1 has a stepped hole 11, and the mounting end of the muffler 2 is installed on the In the step hole 11, a gasket 4 for sealing is also provided between the bottom surface of the step hole 11 and the installation end surface of the muffler 2; An annular side wall 41 formed by extending axially, the inner diameter of the annular side wall 41 matches the diameter of the installation end of the muffler 2 and is sleeved on the installation end of the muffler 2 .

[0024] With the above structure, it is convenient to fix the sealing gasket on the installation end of the muffler through the annular side wall, avoiding the dropping or deviation of the sea...

Abstract

The invention discloses a sealing and heat insulating connection structure for a motorcycle silencer. The sealing and heat insulating connection structure for the motorcycle silencer comprises an engine and the silencer. A stepped hole is formed at the position of an exhaust port of the engine. The installation end of the silencer is installed in the stepped hole through a fixing frame. A sealing gasket used for seal is further arranged between the bottom face of the stepped hole and the end face of the installation end of the silencer. The sealing and heat insulating connection structure for the motorcycle silencer is characterized in that the edge, far away from the center of a circle, of the side, facing the silencer, of the sealing gasket is provided with an annular side wall formed through axial extending, the inner diameter of the annular side wall is matched with the diameter of the installation end of the silencer, and the sealing gasket is arranged at the installation end of the silencer in a sleeving manner. The sealing and heat insulating connection structure for the motorcycle silencer has the beneficial effects of being simple in structure, convenient to install, good in sealing performance, beneficial for the improvement of the assembly efficiency and the heat insulating effect and the like.

Description

technical field [0001] The invention relates to the technical field of motorcycles, in particular to a sealing and heat-insulating connection structure of a motorcycle muffler. Background technique [0002] As a common means of transportation, motorcycles are widely used in people's daily life, and the muffler is an indispensable accessory on motorcycles, and its noise reduction ability also determines the overall quality of motorcycles. , and the installation of the muffler is also one of the factors that affect the muffler ability. [0003] Such as image 3 As shown, one end of the existing motorcycle muffler is inserted into the step hole of the engine exhaust port, and is fixedly installed on the engine through a fixing frame. There is also a gasket between them. Existing sealing gaskets are all annular, and the engine exhaust port is generally arranged obliquely downward, so that the sealing gasket is easy to fall out from the exhaust port, which is not conducive to i...
