Description
【発明の詳細な説明】 この発明は、オートバイのフレームに関スる。[Detailed description of the invention] This invention relates to motorcycle frames.
オートバイは、小型のものでも、フレーム以外に、エン

。Even if a motorcycle is small, there are many parts other than the frame, such as the engine, oil tank, fuel tank, etc., and it requires a lot of man-hours not only for processing but also for managing and assembling the parts, which reduces the manufacturing price. Also, the more parts there are, the heavier the weight will be, and the driving performance will be lower.

に示す笑施例について説明する。In view of the above, the present invention has a frame made of a light alloy by die-casting or the like, and an oil tank, a cylinder head, a cylinder, a crank case, a transmission case, and a fuel tank are built into the frame. In this way, the number of parts can be greatly reduced and the cost can be reduced, and the driving performance can be improved by reducing the weight.Hereinafter, an embodiment of the present invention shown in the drawings will be described.

The frame 4 is divided into a front frame 5 and a rear frame 6, which are connected by a port 7. Further, the front frame 5 and the rear frame 6 are made by being divided into left and right parts, and are connected with bolts. The left and right dividing planes may be in the center as shown in Figures 2 and 3, but depending on the situation or location, they may be moved to one side as shown in Figure 4 (casting method). The oil tank 8 and the cylinder head 9 are integrally installed on the front frame 5. Also, the rear frame 6
The cylinder 10, crankcase 11, transmission case 12, and fuel tank 13 are integrally provided. After the parts of the crank case 711 and the transmission case 12 are assembled, side covers 14 are attached to both sides. Further, a storage compartment 15 is also integrally provided on the rear side of the fuel tank 13. Boss 1 on the rear side of the mission case 12
6 is connected to the rear fork 17. 18 is a carburetor, 19 is an air cleaner, and 20 is a spark plug.

and the rear frame 6, and further divide it into left and right parts and attach the bolts 7.
By connecting the oil tank 8 with
In addition to the engine cylinder head 9, cylinder 10° crankcase 11, and transmission case 12, it is possible to mold them into one piece by incorporating not only the fuel tank 13 but also the engine cylinder head 9, cylinder 10° crankcase 11, and transmission case 12.
