Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a 1P suspension system for a motorcycle.

(Prior art) J to the undulations of the road surface, ru1 to l T';1'! Absorbs and alleviates the vibrations and prevents the propagation of vibrations to the vehicle body. Seat rail 4 near the 1 l bearing part of the M roller 7 fork 3 that supports the wheel 2
11th board 9 with Kutsushikon 5 placed on both sides of the middle break
As shown in Figure 2, the F Luris Bench El tag and the 7-4-3 (in the darkness between the front fj position of the transport 2 and the sea 1 to the rail 4), 1 engine 6 is displayed via link 7, and the engine 8 shown in Fig. A type 6 is known which is connected to the rear fork 3 through a 10.

(Problems that the invention has solved) However, in the case of a two-wheeled vehicle, the height can be lowered. C+ -<t is limited by the human nature of
Limited to the placement of 1 (puu cover).

Therefore, the configuration shown in Fig. 3 was developed, but in this type, the cutter is placed above the Li engine, so the lowest ground level^ [C is reduced, and the lowest ground level - F height L C is increased. Toru, the engine becomes a high-ranking neck, and the Φ heart becomes high.

[F-stage to solve problems]

In order to solve the problem of the wheel suspension, the present invention is designed to solve the problem of wheel mounting.
In the rear wheel suspension system of a two-wheeled vehicle, which is equipped with a dampening device between the rear wheel support member and the vehicle body frame, the rain damping device (jN) is attached to 1) h rear wheel support) 4 parts (small part side of 4). It is characterized by the fact that it is placed in the middle.

(Function) In addition, J, S, C 1-n is low, making it possible to create a motorcycle with a low center of gravity.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 4 to 7.
