Description

Technical Field

[0002] A spring is a mechanical part that uses elasticity to work. When an external force is applied to the spring, the spring will undergo elastic deformation and store elastic potential energy. It is widely used in the suspension system of a car. For example, when a car is driving on a bumpy road, the spring will be compressed to cushion the impact from the road and make the passengers in the car feel more comfortable. Spring wire is a steel wire material used to make springs or similar elastic elements. It is particularly important to safely protect the spring wire before installation.

[0003] A search revealed a new type of thickened spring steel wire for automobiles, with publication number CN214304978U, comprising an outer protective sheath with a plurality of evenly spaced reduction grooves on its outer surface. A central core is disposed within the outer protective sheath, comprising a support core and reinforcing spiral ribs. The outer surface of the support core is evenly wrapped with a plurality of turns of reinforcing spiral ribs, each spirally disposed on the outer surface of the support core. By providing the support core, reinforcing spiral ribs, protective annular outer grooves, outer protective sheath, and reduction grooves, the utility model can enhance the overall strength of the spring after it is made into a spring, providing a higher level of cushioning performance and preventing it from easily damaging. This effectively delays the aging of the spring and extends its service life.

[0004] Based on the above patent, by evenly distributing protective annular outer grooves with uniform spacing on the outer surface of the support core, it can be ensured that the support core will not be damaged when the spring spiral is fully formed, and the internal stress distribution and strength of the support core will not be affected. By providing a reduction groove on the outside of the outer protective sleeve layer, the overall weight of the spring can be reduced, and it can be ensured that the outer surface of the outer protective sleeve layer will not have excessive damage or cracks during the spring spiral bending process, and it can be ensured that the outer protective sleeve layer will not be damaged too quickly when the spring is in use. However, the patent does not provide any settings for the spring steel wire body, and the outer protective structure of the spring steel wire body is too simple. In response to this technical problem, the present application proposes a durable and thickened spring steel wire for automobiles. Utility Model Content
