A seal structure for motorcycle silencer, seal structure installs between the gas outlet of engine and silencer, and the body overcoat of silencer is equipped with sealed pad, and the body of silencer is equipped with the clamp plate outward, sealed pad is located the clamp plate with between the gas outlet, the clamp plate with the engine is connected.
According to the application, the sealing gasket is directly sleeved outside the muffler, so that a step is not required to be arranged in the engine, and the sealing gasket is pressed on the engine through the pressing plate, so that the front end of the muffler is free of the sealing gasket, the cross section area inside the muffler is not influenced even if the sealing section is deformed under the extrusion of the pressing plate, and the exhaust is not influenced, so that the noise elimination effect is not influenced.
Preferably, the muffler is provided with a flange, the flange is welded with the muffler body, the sealing gasket is pressed tightly through the flange, and the pressing plate is located on one side, away from the sealing gasket, of the flange. The sealing gasket is limited by the flange plate, and is extruded by the pressing plate, so that the circumferential stress of the sealing gasket is uniform.
Preferably, the flange plate comprises a first section and a second section, and the first section and the second section are connected to form an L shape. The arrangement can increase the welding area between the flange plate and the muffler, and can effectively weld and prevent the flange plate and the muffler from falling off.
Preferably, the outer diameter of the first section is smaller than the outer diameter of the sealing gasket, so that the sealing effect of the sealing gasket is better.
Preferably, the length of the second section is greater than the thickness of the pressing plate, the inner diameter of the pressing plate is matched with the outer diameter of the second section, and the pressing plate is positioned on the second section, so that the pressing plate and the muffler cannot shake.
Preferably, lugs are arranged on two sides of the pressing plate, and connecting holes are formed in the lugs.
Compared with the prior art, the utility model has the beneficial effects that: according to the utility model, the sealing gasket is sleeved on the muffler, so that the deformation of the sealing gasket can not affect the exhaust cross section area of the muffler, the sealing effect is achieved, the flange plate is extruded by the pressing plate, the sealing gasket is extruded by the flange plate, and the stress of the sealing gasket is uniform.
