Furthermore, the spring body is formed by performing heat treatment on a cold-rolled spring steel strip after punch forming.

The spring body has the advantages that the elasticity of the spring body can be increased, the quality of the spring body is improved, and the service life of the spring body is effectively prolonged.

Further, a plurality of the spring rings are formed by laminating and surrounding a spring steel wire.

The beneficial effects of the utility model reside in that, this kind of setting can increase the compactness of connecting between two sets of spring coils, can effectively prevent that the spring coil after two sets of connections from appearing the phenomenon of rupture.

Further, the damping sleeve is made of a rubber material.

The damping sleeve has the beneficial effects that the rubber material has better elasticity, and meanwhile, the damping sleeve is friction-resistant and corrosion-resistant, and the damping sleeve made of the rubber material is long in service life.

Further, the protective sleeve and the cushion pad are manufactured integrally.

Above-mentioned beneficial effect lies in, this kind of setting can effectively improve the compactness between protective sheath and the blotter, can effectively prevent that rupture phenomenon from appearing in protective sheath and blotter.

The invention has the beneficial effects that: according to the invention, the damping sleeve is arranged between the spring bodies, the damping sleeve has a good damping effect, and the damping sleeve is matched with the spring bodies, so that the damping effect is good. The damping effect of the spring body can be further effectively improved through the buffer cushion arranged in the damping sleeve, namely when the spring body is under pressure, the protective sleeve and the buffer cushion can convert the pressure into elastic deformation, so that the damping effect is achieved; the invention has simple structure, convenient use, low production cost and easy popularization.

Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and it should be understood that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1 and 2, the invention provides an automobile damping spring, which comprises a spring body 1, wherein the spring body 1 is formed by combining a plurality of spring rings 2, the plurality of spring rings 2 are sequentially distributed from top to bottom, the upper end spring ring 2 is connected with the lower end spring ring 2 end to end, the lower end of the spring ring 2 is provided with a damping sleeve 3, the damping sleeve 3 is composed of a protective sleeve 301 and a buffer pad 302, the buffer pad 302 is arranged at the bottom end inside the protective sleeve 301 and connected with the protective sleeve 301, the inner side wall of the protective sleeve 301 is connected with the side wall at the lower end of the spring ring 2, and the buffer pad 302 is connected with the bottom end of the spring.
