Detailed Description

The present invention will be further described with reference to the following examples and the accompanying drawings.

As shown in figure 1, the upper side and the lower side of the front part of a motorcycle frame are respectively provided with a frame main pipe A and a front inclined pipe B.

As shown in fig. 2 and 3, the frame main tube a is formed by welding a first support member 1 and a second support member 2, wherein the first support member 1 has an upper horizontal section 1a and upper longitudinal sections 1b extending downward from both ends of the upper horizontal section 1a in cross section, the two upper longitudinal sections 1b extending downward make the first support member 1 form a first opening 11 with a downward opening, the second support member 2 has a lower horizontal section 2a and lower longitudinal sections 2b extending upward from both ends of the lower horizontal section 2a in cross section, the two lower longitudinal sections 2b extending upward make the second support member 2 form a second opening 21 with an upward opening, the two upper longitudinal sections 1b correspond to the two lower longitudinal sections 2b one by one and are welded together, respectively, after the first support member 1 and the second support member 2 are welded together, the first opening 11 is opposite to the second opening 21, and encloses a hollow part forming the frame main pipe A.

Because the first supporting part 1 and the second supporting part 2 are both non-closed components, the first supporting part 1 and the second supporting part 2 can be formed by adopting a sheet metal or other non-elbow process, so that the frame main pipe A can avoid the cracking defect caused by the elbow process. In this embodiment, the first support member 1 and the second support member 2 are both sheet metal parts for ease of manufacturing.
