Problems solved by technology

[0006] In the case of the above example, in order to stabilize the shape during deformation, the bolts are used in the state of passing through the round holes 04a, 05a, and 03a of the upper side 04, the lower side 05, and the connecting part 03. There is a danger of bending the small part of the connection part 03 of the cylindrical body, and the shape during deformation is unstable, and it is difficult to always obtain the required load-displacement characteristics
[0007] If there is no supporting member such as bolts, it will not be able to absorb compressive energy stably
[0008] Due to the necessity of a supporting member, the applicable occasions are also limited and lack of versatility

Embodiment Construction

[0029] specific implementation

[0030] Method: according to the following Figure 1-7 One embodiment of the present invention will be described.

[0031] figure 1 It is a partly omitted side view of a scooter-type motorcycle 1 to which the damping force generating device of this embodiment is applied to a wheel suspension device.

[0032] A low-slung floor 4 is formed between the front part 2 and the rear part 3 of the vehicle body. A down frame 6 extending downward from a front pipe 5 of the front part 2 is bent rearward at the lower end to form the floor 4 .

[0033] A steering shaft 7 is rotatably embedded in the front pipe 5. A pair of left and right front forks 8 are integrally mounted on the lower end of the steering shaft 7 and extend downward. The lower end of the front fork 8 is freely swingable by a pivot arm bolt 11. ground supports the rocker arm 9 as a link member.

[0034] A front wheel 13 is supported at the free end of the rocker arm 9 via a front axle 12...

Abstract

To provide an elastic compressive spring 20 which is deformed into a stable form without a support member and has normally a desired load- deformation characteristic. In an elastic compressive spring 20 comprising an elastically deforming cylindrical spring body 21 for absorbing compression energy generated by radial pressure, a base 24 is formed at a side to receive pressure of the spring body 21 so as to extend in a plane vertical to the pressure direction to define a flat bottom surface, and a reinforcing wall 26 is integrally formed to connect the extended part of the base 24 to a side part of the cylindrical spring body 21.

Description

Technical field: [0001] The present invention relates to a compression spring made of resin or rubber elastic body. Background technique: [0002] As an example of the prior art, the compression spring is formed into a cylindrical elastic body, and compressive energy is absorbed by being elastically deformed into a flat shape by a radial pressing force. [0003] As one of the specific examples, the compression spring described in Japanese Patent Publication No. Hei 7-502698 is as follows: Figure 9 As shown, two cylindrical elastic bodies 01, 02 are overlapped in the radial direction to form a cylindrical body, the connecting part 03 is small, and the upper side 04 and lower side 05 are flat. [0004] Circular holes 04a, 05a, and 03a for passing bolts are coaxially formed on the upper side 04, the lower side 05, and the connecting portion 03, respectively. [0005] Under the action of radial pushing, the two cylindrical elastic bodies 01 and 02 are elastically deformed into...
