性能が得られるようにしたもので、以下第２図及び第３
図に示す本発明の実施例について説明する。As shown in Figure 1, after attaching the front end to the lower part of the car body A, the rear axle D of the rear wheel C is attached to the rear end of the Hawk B, and the rear axle D of the rear wheel C is attached to the rear end of the Hawk B and the upper part of the car body A. A cushion unit E is placed between them. motorcycle cushion,
It is desirable that the grip be soft at the beginning and strong so that it does not bottom out at the end, but in this device, the part where the cushion unit E connects to the rear hawk B is constant, that is, the lever length of the rear hawk B is fixed. Since is constant, the cushioning performance can only be improved by improving the cushioning unit E, and there is a limit to the cushioning performance. This invention is
The rear fork and the holding part of the cushion unit are made movable to change the effective lever length of the rear fork to obtain good cushioning performance, as shown in Figures 2 and 3 below.
An embodiment of the present invention shown in the figures will be described.
車体１の下部に後ホーク２の前端を揺動自在に軸着し、
後ホーク２の後端に、後輪３を回転自在に支承する後車
軸４を取着する。The front end of the rear fork 2 is pivotably attached to the lower part of the vehicle body 1,
A rear axle 4 rotatably supporting a rear wheel 3 is attached to the rear end of the rear fork 2.
後ホーク２の腕部５には、保持金具６を揺動自在に挿入
する。７は塵をシールするシール片である。A holding fitting 6 is swingably inserted into the arm portion 5 of the rear fork 2. 7 is a seal piece that seals out dust.
そして、保持金具６に、リンクバー８の後端と、クッシ

。Then, the rear end of the link bar 8 and the lower end of the cushion unit 9 are firmly attached to the holding fitting 6. The front end of the link bar 8 is pivoted to the lower part of the vehicle body 1, and the upper end of the cushion unit 9 is fixed to the upper part of the vehicle body 1. The effect will be explained.
後車軸４は後ホーク２の前端軸着部を中心にして後ホー
ク２を揺動させて上下にクッションする。The rear axle 4 swings the rear fork 2 around the front end shaft attachment part of the rear fork 2 to cushion it up and down.
これに対し、リンクバ−８は一定長さであるので、保持

る。On the other hand, since the link bar 8 has a constant length, the holding fitting 6 slides back and forth on the arm portion 5 of the rear fork 2. On the extension side where the rear axle 4 goes down, the holding metal fitting 6 moves forward, and on the compression side where the rear axle 4 goes up, the holding metal fitting 6 moves rearward. Thus, at the beginning of the cushion, the lever
A short ratio provides a soft cushion, and as the compression increases, the lever ratio increases, making the cushion stronger and preventing the discomfort of the cushion hitting the bottom. In this way, a good cushion can be created. As explained above, the present invention has a front end pivotably attached to the lower part of the vehicle body, a rear axle attached to the rear end of the hawk, and a holding metal fitting slidably inserted into the arm of the rear hawk. The rear end of the link bar and the lower end of the cushion unit are pivotally attached to the holding metal fittings, the front end of the link bar is pivoted to the lower part of the vehicle body, and the upper end of the cushion unit is pivoted to the upper part of the vehicle body, so that the cushion can be held together with the cushion. Since the metal fittings slide, the lever ratio of the cushion unit to the rear fork can be varied. As a result, it is possible to obtain a soft cushion at the beginning of the cushioning, and to increase the cushioning force as the compression increases, thereby achieving good cushioning performance. Also, on the extension side, reduce the lever ratio,
It can also reduce the inertia of the rear wheels. Further, the amount of sliding of the holding fitting can be appropriately selected depending on the mounting position of the front end of the link bar.
