。The motorcycle was welded to the front end of the frame.
The front fork is rotatably connected to the r tube.The front fork is connected to the outer tube by inserting it so that it can slide under the inner tube and provide cushioning. An inner tube is inserted and connected so that it can be slid and cushioned.The one with this outer tube on the upper side is called an inverted type front hawk.This inverted type front hawk can be manufactured with high rigidity. Therefore, as shown in Figures 4 and 5, the head pipe B is welded to the front end of the frame A, and the lower part of the head pipe B and the bottom of the frame A are connected. Add and weld reinforcing plates C to both sides of the side, and further weld a reinforcing piece to the top of the reinforcing plate C from the head pipe B toward the rear side to increase the rigidity of the head pipe B. It is designed to be able to withstand the impact loads of F] and F2 applied by the head vibration B.
フレームＡの前部とヘッドパイプＢの両側に補強板Ｃを
溶着し、更に補強板Ｃに重ねて補強片りを溶着するので
、溶着作業が多く、製造コストが高くつき、溶着歪が発
生し易くて、精度を保つのが大変である。Reinforcing plates C are welded to the front of frame A and both sides of head pipe B, and reinforcing pieces are welded over the reinforcing plates C, which requires a lot of welding work, increases manufacturing costs, and causes welding distortion. It's easy, but it's difficult to maintain accuracy.

ームを得ることを１」的とする。In view of the above, this invention has a head pipe welded to the front end of the frame, the front end of a reinforcing plate attached in a U-shape to the lower front part of the frame welded to the head vibe, and the rear part of the reinforcing plate is shaped like a horizontal V.
The objective is to obtain a high-precision automobile frame at low manufacturing cost by extending the frame backward in a letter-shaped manner to increase its strength.

レームの両側に溶着するようにしたことにある。In order to achieve the above object, the motorcycle frame of the present invention has a head vibe that connects the front fork welded to the front end of the frame, and the left and right front ends of the reinforcing plate attached in a U shape to the front lower part of the frame are connected to the lower left and right parts of the head pipe. The left and right rear portions of the reinforcing plate extend diagonally downward and rearward in a substantially horizontal V-shape, and are welded to both sides of the frame.

subject to impact loads. The reinforcing plate extends in a substantially horizontal V-shape toward the frame side, and can be particularly rigid against F2 force.
そして、溶着箇所も少く、溶着歪が少くてフレームの製
作精度を高く保つことができる。Furthermore, there are fewer welded parts and less welding distortion, making it possible to maintain high manufacturing precision of the frame.
以下、本発明の実施例を第１図乃至第３図によって説明
する。Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.
フレーム１の前部は、タンクレール２とダウンチューブ

フレーム］の前端にヘットバイブ５を溶着する。ヘッド
バイブ５には、前ホークロの上部のステアリング軸を回
動自在に連結する。The front part of the frame 1 is constructed by welding and connecting both sides of a tank rail 2 and a down tube 3 using stiffeners 4.
Weld the head vibe 5 to the front end of the frame. The head vibe 5 is rotatably connected to the steering shaft at the top of the front crosshair.
補強板７は、Ｕ字状に曲げてあって、フレーム１の前下
部のダウンチューブ３部分を巻くように添え、左右前端
をヘッドバイブ５の両側に溶着する。The reinforcing plate 7 is bent into a U-shape, is attached so as to wrap around the down tube 3 portion at the front lower part of the frame 1, and the left and right front ends are welded to both sides of the head vibe 5.
補強板７の左右後部は、ダウンチューブ３に沿わせて斜

側に溶着する。尚、補強板７はＵ字状に曲げた下端で切
断し、左右別体のものにしてもよい。The left and right rear portions of the reinforcing plate 7 are formed in a substantially horizontal V-shape along the down tube 3 on the diagonal lower side and the rear side, and are welded to both sides of the frame 1. Incidentally, the reinforcing plate 7 may be cut at the lower end bent into a U-shape to form separate left and right pieces.

できる。Head vibe 5 is Fl and F2 from the connected front cross
subject to impact loads. The reinforcing plate 7 is placed diagonally downward along the down tube 3 and extends rearward at a substantially right angle to the head vibe 5 to form a substantially horizontal V-shape and welded to the frame. The rigidity of the lower part can be increased.

、仕上りの体裁もよい。As explained above, since the present invention is constructed as described above, the reinforcing plate for reinforcing the lower part of the head pipe and the front end of the frame extends in a substantially horizontal V-shape in the down tube direction and rear side, so that rigidity is improved. can be significantly increased. Further, there is no need to further weld a reinforcing piece onto the reinforcing plate, reducing welding work and reducing manufacturing costs. In addition, welding distortion is reduced, the manufacturing precision of the frame can be improved, and the finished appearance is also good.
