ている。(Prior art) Conventionally, when assembling a rear suspension connected to the rear wheel of a motorcycle, as shown in Fig. 1, the upper end of the suspension 1 is pivoted to the upper part of the rear frame 3 extending downward from the main frame 2, and the lower end is pivoted to one end of the bell crank 4, and the other end of the bell crank 4 is provided at the lower end of the rear frame.
The bell crank 4
A structure in which the intermediate point of the swing arm 7 and the intermediate point of the swing arm 7 are connected by a push rod 8 has been put into practical use.

る。 With the above configuration, the load applied from the push rod 8 via the bell crank 4 is received by the bracket 6 protruding from the cross pipe 5. Therefore, the bending moment M that the bracket 6 receives, as shown in FIG. 2, is M=FL, where L is the distance from the center of the cross pipe 5 to the center of the bracket shaft hole, and F is the pressure applied to the bell crank 4. The moment M causes twisting in the cross pipe 5 in proportion to the distance L, and the rigidity of the cross pipe 5 becomes a problem. In addition, there is Utility Model Application Publication No. 57-46089 as a prior art.

シヨン組付構造を提供しようとするものである。(Purpose of the invention) This invention was made in view of the above points, and the center of the cross pipe and the axis of the bell crank shaft attachment part are arranged on the same axis to prevent twisting.
The present invention aims to provide a motorcycle rear suspension assembly structure that eases the requirement for rigidity and allows the use of small-diameter, thin-walled steel pipes, as well as cross pipes made of lightweight aluminum or aluminum alloys with good workability. It is something to do.

る。 The cross pipe 9 of this invention is divided and cut out at the center to form a gap 10. Then, the sleeve 12 is inserted into the shaft hole 11 of the bell crank 4, and the sleeve 12 is inserted into the gap 10 of the cross pipe 9, and the shaft 14, which is inserted into the shaft hole 13 provided at the center of the cross pipe, is passed through the sleeve shaft hole. 4 is attached to the shaft.

実用的効果を奏する。(Function/Effect) Therefore, in the structure of this invention as described above, the cross pipe is divided and the end of the bell crank is inserted into it, and the bell crank is fixed by the shaft inserted through the center of the cross pipe. Therefore, the load applied through the bell crank is directly received by the shaft inserted through the center of the cross pipe, and compared to the conventional mounting structure with a protruding bracket, the cross pipe is subjected to a force that causes twisting due to bending moment. This reduces the requirement for cross pipe rigidity, allows the use of small-diameter, thin-walled steel pipes, and allows the use of lightweight aluminum and alloys with good workability, contributing to the weight reduction of the car body.
In addition, assembly work is easy and costs are reduced.
Furthermore, there are no protrusions such as brackets and the appearance is good, which provides practical effects.
