Embodiment Construction

[0011] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0012] Such as figure 1 and figure 2 As shown, a front body assembly of a motorcycle frame that is convenient for welding the oil pool includes a head pipe 1, a front main pipe 2 and a front inclined pipe 3 are welded on the same side of the head pipe 1, and the front main pipe 2 and the front inclined pipe 3 are welded on the same side. Front support pipe 4 is welded between. The head pipe 1, the front main pipe 2, the front inclined pipe 3 and the front support pipe 4 are all straight pipes.

[0013] The lower part of the front main pipe 2 is provided with an upper mounting bracket assembly 10 on the rear shock absorber, the upper mounting bracket assembly 10 on the rear shock absorber is welded with a left main pipe 5a and a right main pipe 5b, and the lower part of the front inclined pipe 3 is welded with a left lower main pipe 6a and a right Lower su...

Abstract

The invention discloses a motorcycle frame front body assembly convenient for welding an oil pool, and the motorcycle frame front body assembly comprises a head tube, wherein a front main tube and a front oblique tube are arranged on the same side of the head tube; a front supporting tube is arranged between the front main tube and the front oblique tube; the head tube, the front main tube, the front oblique tube and the front supporting tube are respectively of a straight tubes; the lower part of the front main tube is provided with a left main tube and a right main tube; the lower part of the front oblique tube is provided with a left lower main tube and a right lower main tube; an angle formed between the front main tube and the horizontal line is 24DEG; an angle formed between the front oblique tube and the plumb line is 17DEG; and an angle formed between the supporting tube and the horizontal line is 12DEG. By optimizing the angle of the tubes surrounding the oil cooling oil pool, the welding difficulty of the oil pool is greatly alleviated, the production working hours of a frame can be reduced, the service life of the frame can be prolonged, and the oil leakage probability of a frame oil cooling system can be reduced.

Description

technical field [0001] The invention relates to a frame structure of a motorcycle, in particular to an assembly of a front body of a motorcycle frame. Background technique [0002] The welding assembly of the front body of the motorcycle frame includes a head tube, a front main pipe of the frame and a front inclined pipe are welded on the same side of the head pipe, and a front support pipe of the frame is welded between the front main pipe of the frame and the front inclined pipe. The bottom of the front main pipe is provided with left and right main pipes, and the bottom of the front inclined pipe is welded with left and right lower main pipes. The area formed between the head pipe, front main pipe, front inclined pipe and front support pipe is used for welding the oil cooler oil pool, and the area formed between the front support pipe, front main pipe, front inclined pipe, left and right main pipes and left and right lower main pipes is used for Install the engine. The ...
