(Prior Art) Rear wheel cushioning of a motorcycle is normally achieved by interposing a cushion unit between a swing arm that supports the rear wheel at its rear end and a vehicle body frame. One way to do this is to install a cushion unit in the center of the vehicle body and connect it to the swing arm using a bell crank tube. In this case, since the swinging portion is located at the center of the vehicle body frame, it is necessary to increase the rigidity of the vehicle body frame.
(Problems to be solved by the invention) In a motorcycle with such a structure, in addition to increasing the rigidity of the body frame as described above, it is also necessary to reduce the moment of inertia of the movable parts and improve the lever ratio characteristics. There are demands such as making it possible to make it progressive.The object of the present invention is to obtain 1) a shock device for a motorcycle that satisfies these requirements.

(Means for Solving the Problems) As a means for solving the above-mentioned problems, the present invention provides a swing arm that supports the rear wheel at its rear end by forming two arms and a cross member connecting the two arms. At the same time, a bracket is made to protrude below the 7-m frame from the cross member, one end of the bell crank is pivotally connected to the bracket, and a cushion is provided between the other end of the bell crank and the upper part of the 7-m frame of the vehicle body. A compression rod is used to connect the middle part of the bell crank, which is located forward of a line connecting both ends of the bell crank, to the vehicle body frame.

(Function) With this configuration, the bell crank, cushion unit, etc. can be placed near the center of the main body, so the moment of inertia can be reduced, and since there is more piping in the center of the frame, the rigidity is increased. Furthermore, the lever ratio characteristics can be made progressive.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. 1 is the body frame, 2 is its main tube, 3 is the body tube, and 2 is the seat rail. The body tube 3 is divided into two parts, left and right, as shown in Fig. 2, and consists of a bracket 4 provided in a part of the body tube 3, two arms 5.5, and a member 6 that connects them. The front end of the swing arm 7 is pivotally connected to a shaft 8.

A cushion unit 12 is pivotally mounted between the upper end of the bell crank 10 and the upper part of the vehicle body frame 1 by a shaft 13.14 (not shown in FIG. 2). At some point, the intermediate portion is between both ends of the bell crank 100, that is, the swing arm 7
It is located forward of the line (imaginary line) connecting the pivot point between the cushion unit 12 and the lower end of the cushion unit 12. Then, one congress min rod 16. are shafts 17 and 18
is combined with Cross tube 15 and main tube 2
A reinforcing tube 19 is provided between the rear end and the rear end (effects of the invention). can be collected in. Since the mass of the cushion unit can be placed near the center of gravity of the vehicle body, the moment of inertia of the movable parts can be reduced.
