Problems solved by technology

Since the bracket 1 is fixed on one side in the air, the structural strength is poor, and it is prone to deformation and out of shape, which makes the direction of the secondary air supply valve change, so that the hose connected to the secondary air supply valve will be in contact with the frame, fuel tank, etc. The components interfere, and with the repeated friction between the hose and related parts, the hose is easily worn out and air leakage occurs, resulting in the failure of the secondary air supply valve

Embodiment Construction

[0013] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0014] Such as figure 1 , figure 2 As shown, the present invention is made of support 1 and front main pipe 2 of vehicle frame, and front main pipe 2 of vehicle frame adopts prior art, and its structure and arrangement form are not repeated here. The bracket 1 is a rectangular flat plate structure, the long side direction of the bracket 1 is in the same direction as the axis of the front main pipe 2 of the vehicle frame, and one of the long sides of the bracket 1 is welded with the front main tube 2 of the vehicle frame, and the other side near the bracket 1 There are through holes at both ends of the board surface of the long side, so that the secondary air supply valve can be installed on the bracket 1 through bolts. A building block 3 is formed on the bracket 1 by stamping, the building block 3 is rectangular, and the long side of the building block 3 ...

Abstract

The invention discloses a motorcycle secondary gulp valve bracket mounting structure, comprising a bracket (1) and a frame front main pipe (2), wherein the bracket (1) is in a rectangular plate structure, one long edge of the bracket (1) is welded with the frame front main pipe (2); a lapping block (3) is formed on the bracket (1) through stamping; the lapping block (3) is in a rectangular shape; one long edge of the lapping block (3) is connected with the top side of the bracket (1); gaps are left between the other three edges of the lapping block (3) and the top side of the bracket (1); and the other long edge of the lapping block (3) is welded on the frame front main pipe (2). In the invention, the lapping block is stamped on the bracket and then is welded on the frame front main pipe, thus not only strengthening the firmness of the connection between the bracket and the frame front main pipe, but also greatly increasing the strength of the structure and effectively preventing the deformation of secondary gulp bracket.

Description

technical field [0001] The invention relates to a motorcycle component, in particular to a mounting structure of a motorcycle secondary air supply valve bracket. Background technique [0002] The secondary air supply valve of the motorcycle is installed at the front of the frame. The fresh air in the air filter can enter the exhaust port of the cylinder head through the secondary air supply valve, so that the exhaust gas containing CO, NO, HC and other compounds that cannot be fully combusted After secondary combustion, the mixed gas is discharged through the muffler of the exhaust pipe. The installation method of the traditional secondary air supply valve is as follows: image 3 , Figure 4 As shown, the bracket 1 connected to the secondary air supply valve (not shown in the figure) is a rectangular flat plate structure, and one long side of the bracket 1 is welded to the front main pipe 2 of the vehicle frame. Since the bracket 1 is fixed on one side in the air, the stru...
