Embodiment 1

[0017] Such as figure 1 A kind of spring shown, this spring is wound with steel wire, comprises spring outer ring 1 and 2, spring inner ring 3, wherein, spring outer ring is larger than spring inner ring caliber. The overall shape of the spring is that two tower-shaped springs are connected by small ends, such as figure 2 shown.

[0018] The spring of this shape is equivalent to the combination of two pagoda springs with small heads facing each other, but the stroke space can be greatly reduced. Compared with the combination of two pagoda springs with small heads facing each other, the material is reduced and the cost is saved. Moreover, the spring of this shape has the characteristics of shock absorption and not easily deformed. It is suitable for any mechanical structure that requires tension damping, especially in structures with limited space. The shock-absorbing buffer spring replaces the buffer rubber sleeve in the motorcycle clutch, can enhance the service life of t...

Embodiment 2

[0020] Such as image 3 As shown, the shock absorbing buffer spring is elliptical in plan view.

Embodiment 3

[0022] Such as Figure 4 As shown, the shock absorbing buffer spring is diamond-shaped in plan view.

[0023] When the spring is working, the outer ring is fixed in a circular hole, and the inner ring is fixed on a cylinder. When there is a lateral displacement between the circular hole and the cylinder, there will also be a dislocation between the inner ring and the outer ring of the spring. Due to the composition of the spring The rigidity of the steel wire itself plays the role of buffering and shock absorption, which is to use the misalignment of the inner and outer rings of the spring to buffer the displacement of the external force of shock absorption. A spring steel wire is used to wind the inner ring and the outer ring, and the misalignment of the inner ring and the outer ring produces a buffering effect.

Abstract

The embodiment of the invention discloses a spring, which comprises a first spring outer ring, a second spring outer ring and a spring inner ring which are coiled by using a steel wire, wherein the first spring outer ring and the second spring outer ring are distributed on two sides of the spring inner ring, and the calibers of the first spring outer ring and the second spring outer ring are larger than the caliber of the spring inner ring. The spring with the shape has the characteristics of buffering and difficult deformation. The spring with the shape is equivalent to the combination of two pagoda springs with opposite small ends, thereby greatly reducing the stroke space, and compared with the combination of the two pagoda springs with the opposite small ends, the spring reduces materials and saves the cost. Besides, the spring with the shape has the characteristics of buffering and difficult deformation. The spring is applicable for any mechanical structure requiring tension buffering, in particular to the structures with limited forming spaces. The buffering spring replacing a buffering gum cover in a clutch of a motorcycle can prolong the service life of the clutch and can play a role of buffering.

Description

technical field [0001] The invention relates to the technical field of springs, in particular to a shock absorbing buffer spring for motorcycles. Background technique [0002] At present, the clutch cover combination that motorcycle uses is made up of clutch housing, buffer rubber sleeve, driven gear. The driven gear is set on the boss of the clutch housing, and a buffer rubber sleeve is arranged between the two. The driven gear is clamped through the cover plate and fastened with a rivet column, so that the driven gear is fixedly connected with the clutch housing. The power of the engine is transmitted from the driven gear to the clutch housing through the buffer rubber sleeve, then from the clutch housing to the active friction plate, then from the active friction plate to the driven friction plate, then from the driven friction plate to the center sleeve, and then to the center Sequentially transfer torque from sleeve to spindle. Because the buffer rubber sleeve is gene...
