Embodiment Construction

[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0015] Such as figure 1 , figure 2 As shown, the present invention is composed of the muffler connecting plate 2 fixed on the outer wall of the muffler 1, the frame connecting bracket 4 fixed on the main pipe of the frame 3, the bolt 5, the washer 6 and the washer seat 7 and other parts, and the muffler connecting plate 2 is passed through the bolt 5 is fixed on the vehicle frame connecting bracket 4. The muffler connecting plate 2 is parallel to the axis line of the muffler 1, and is composed of two flat plates. The two flat plates are bonded together, and their inner ends are turned up or down respectively and welded on the muffler 1. The frame connection bracket 4 is composed of two flat lugs 4a and screw sleeves 4b. The two flat lugs 4a are respectively welded on the main pipe 3 of the vehicle frame through the flanging of their outer ends. 4a, and we...

Abstract

The invention discloses a mounting bracket assembly for a muffler of a motorcycle, which comprises a muffler connecting plate (2) fixed on the outer wall of the muffler (1) and a frame connecting bracket (4) fixed on a frame main pipe (3), wherein, the muffler connecting plate (2) is fixed on the frame connecting bracket (4) through a bolt (5), the bolt (5) between the muffler connecting plate (2) and the frame connecting bracket (4) is sleeved with a gasket (6) and a gasket seat (7), and surfaces which are contacted between the gasket (6) and the gasket seat (7) are mutually-matched spherical surfaces. The mounting bracket assembly has smart concept, a simple structure and easy implementation, can effectively prevent welding positions between the muffler and an exhaust pipe from rupturing due to stress concentration, improves the service life of the muffler, and ensures that the muffler and a frame have firmer connection at the same time.

Description

technical field [0001] The invention belongs to the technical field of motorcycles, and in particular relates to a motorcycle muffler mounting bracket combination. Background technique [0002] Between the traditional motorcycle muffler and the vehicle frame, the muffler connecting plate and the vehicle frame connecting bracket are directly connected together with bolts. Ideally, the muffler connecting plate and the frame connecting bracket are just parallel to each other. The front end of the muffler is welded to the rear end of the exhaust pipe, and the front end of the exhaust pipe is installed on the engine cylinder head. Due to the inherent errors in the manufacture of the frame connecting bracket and the muffler connecting plate, and the process of installing the rear end of the muffler to the frame, it is difficult to ensure that the frame connecting bracket and the muffler connecting plate are in place in one step due to human operation. To the extent that the two ...
