Problems solved by technology

[0004] Although this single-cone suspension spring can withstand high-frequency reciprocating compression movement, and the collision between the springs is not easy to make noise when subjected to a large impact, but in the process of use, the two ends of the spring body directly contact the shock absorber. contact with other parts of the spring, it is easy to cause wear at both ends of the spring

Embodiment 1

[0033] Embodiment 1: a kind of front damping spring of automobile, as figure 1 As shown, it includes a spring body 1 rolled by spring steel wire. The left side of the spring body 1 is a large end portion 2 , and the right side is a small end portion 3 . The material of the spring steel wire is 55CrSiA, the diameter is 12-13mm, and the hardness is 50-51.5HRC; the inner diameter of the small end 3 is Φ79.5±0.5, the outer diameter of the big end 2 is Φ139.5±0.5, and the number of turns is 7.65 , Free length 456±3mm, rotation to the right.

[0034] Such as figure 2 and image 3 As shown, the antistatic paint is sprayed onto the surface of the spring body 1 through a spray gun to form an anti-corrosion layer 7, which can increase the anti-corrosion performance and antistatic performance of the spring body 1.

[0035]At the same time, the first rubber sleeve 4 is set on the large end portion 2 of the spring body 1, and the second rubber sleeve 5 is set on the small end portion 3...

Embodiment 2

[0036] Embodiment 2: a kind of production technology of the front damping spring of automobile, as Figure 1 to Figure 3 As shown, it includes the following steps in turn: preparation process, coil spring process, tempering process, shot peening process, standing process, cleaning process, phosphating operation process, first inspection process, surface spray treatment process, load grouping process, set Rubber cover process, second testing process, packaging process.

[0037] In the preparation process, select spring steel wire made of 55CrSiA, with a diameter of 12-13mm and a hardness of 50-51.5HRC.

[0038] In the spring coiling process, the spring coiling machine is used to operate, and the rotation of the front damping spring is set to the right, and the large end 2 is rolled out first, and then the small end 3 is rolled out; at the same time, the inner diameter of the small end 3 is set Φ79.5±0.5, the outer diameter of the big end 2 is Φ139.5±0.5, the number of turns is...

Abstract

The invention discloses a front damping spring for an automobile. The front damping spring comprises a spring body formed by coiling a spring steel wire. One end of the spring body is a large end part, and the other end of the spring body is a small end part, wherein the inner diameter of the small end part is smaller than that of the large end part after coiling. The large end part is sleeved with a first rubber sleeve, and the small end part is sleeved with a second rubber sleeve. The second rubber sleeve is provided with an opening groove which is formed in the extending direction of the spring body. The inner wall of the second rubber sleeve is evenly provided with a hot melt adhesive coating. The front damping spring has the following beneficial effects that the first rubber sleeve and the second rubber sleeve are arranged at the two ends of the spring body correspondingly so that stress protection can be achieved on the front damping spring, the two ends of the front damping spring are not likely to be abraded, and the pressure intensity during stress can be reduced; and due to the hot melt adhesive coating, good stripping strength can be achieved between the second rubber sleeve and the spring body.

Description

technical field [0001] The invention relates to the field of springs, in particular to a front damping spring of an automobile and a production process thereof. Background technique [0002] The front shock absorber of a car is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the road surface. When passing through an uneven road, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will reciprocate, while the front shock absorber The vibrator is used to suppress this spring jump. In the process of shock absorption, the front shock absorber spring plays a vital role in shock absorption. [0003] The authorized announcement number is CN201475222U, and the Chinese patent issued on May 19, 2010 discloses a single-cone suspension spring, which includes a helical spring body wound by a spring steel wire, and one end of the spring main body The spring body is a cone. [0004] A...
