である。[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to a front wheel suspension system that cushions and supports the front wheel of a motorcycle, and in particular, the present invention relates to a front wheel suspension system that cushions and supports the front wheel of a motorcycle. The present invention relates to a so-called leading link type or trailing link type shock absorber which supports a front wheel and connects a shock spring in the middle thereof.

いる（例えば実公昭３２−１、１１２３号公報、実公昭
４４−４５８２号公報、実公昭４６−１４８０７号公報
など）。Leading link type or trailing link type front wheel suspension systems for motorcycles are often used in small motorcycles because their unsprung weight is light and the structure is simple (for example, Japanese Utility Model Publication No. 32-1, 1123). Publication, Utility Model Publication No. 44-4582, Publication Utility Model Publication No. 46-14807, etc.).

。However, due to the structure of a front wheel suspension system such as a leading link type, when the swinging arm supporting the front wheel swings, the rod connecting the swinging arm and the buffer spring also swings. The main pipe cannot be used as a guide tube for the piston rod, and the entire shock absorber including the spring and guide tube must be swung, making it difficult to simplify the structure.

がおる。The purpose of this invention is to solve the above-mentioned problems. A support arm is provided at the lower end of the main pipe of the front fork, and the other end of the swinging arm, which supports the front wheel at one end, is rotated by the support arm. A piston is freely supported and slidably provided in the main pipe, and a swinging arm is connected to the swing arm by a rod, and the piston is resiliently downwardly repelled by a spring. It is distinctive in that it is swingably supported.

A pin 9a is fixed to the lower end of the piston rod 9, and the platen 9a is rotatably connected to the swinging arm 5 via a pin 11. ing. The screw I/N 7 consists of two washers 7a and 7b provided at the upper end of the piston rod 9, and a rubber-like elastic EJ7c interposed between them. The upper end of the piston rod 9 is guided in the axial direction along the inner surface of the main pipe 2 by the elastic ring 7cK, and is allowed to tilt due to its elastic deformation. 12 is a pusher slidably fitted to the piston rod 9, and supports the p1 piston rod 9 approximately on the axis of the main pipe 2, improving ease of assembly. Reference numeral 13 is a support ring for the bush 12, which is supported at the lower end of the main pipe 2 by a circlip 14, and supports 17 the bush 12 via a spring 15. 16 is a rubber damper, 17
Reference numeral 18 indicates a rubber spoon for dustproofing and waterproofing, and 18 indicates a steering shaft for attaching the front fork 1 to the vehicle body frame (not shown).

。According to this embodiment, when the vehicle is running, the front wheels 3 are connected to the main pipe 2.
When it moves up and down with respect to, the swing 95 swings up and down accordingly. The upward movement of the swinging arm 5 is accompanied by the upward movement of the bracket 9a, the piston rod 9, and the piston I, and the spring 8 is compressed. When the action of pushing up the front wheel 3 stops, the elasticity of the spring 8 causes the swinging arm 5 to move downward through the reverse process. Thus, a damping effect on the front wheels 3 is achieved.

In addition, the elastic ring IC compresses and expands at its front and rear to absorb the above-mentioned rocking motion, and no gap is created in the radial direction between the elastic ring IC and the main pipe 2, so the piston 7 does not cause any wobbling. Slides smoothly.

削減出来る効果がある。As described above, this invention provides a support arm at the F end of the main pipe of the front fork, and provides a force for rotatably supporting the other end of the swinging arm, which supports the front wheel at one end, on the support arm. A piston that can slide freely inside the main pipe and a swinging arm are connected by a rod,
In the device in which the piston is forced downward by a spring, the piston and the piston rod are swingably supported with respect to the main pipe, so the vertical movement of the swinging arm is allowed by the tilting of the piston rod. . Therefore, there is no need to prepare a cylinder separately from the main pipe as in the past, which not only simplifies the structure but also greatly reduces the weight of the vehicle.
