Abstract

A coil spring mounting structure for a suspension strut includes a spring bracket secured to a shock-absorber. The spring bracket has a coupling hole, which is configured to receive a screw threaded end of a coil spring. Nuts are screw-coupled to the screw threads of the coil spring, thereby fixing the coil spring to the spring bracket.

Claims

1. A coil spring mounting structure for a suspension strut comprising:

a spring bracket fixed to a body of a shock-absorber and having a coupling hole;

a coil spring inserted into the coupling hole, the coil spring having screw threads formed on an end thereof;

nuts screw-coupled with the screw threads for fixing the coil spring to the spring bracket;

a second bracket fixed to the shock-absorber;

a clamp located on a surface of the second bracket;

bolts and nuts for fixing the second bracket and the clamp; and

a bushing between the clamp and the coil spring, said bushing having an aperture.

2. The coil spring mounting structure for a suspension strut according to claim 1, further comprising projection jaws formed on more than one side of the bushing and a slit formed between the aperture and an outer surface of the bushing.

3. The coil spring mounting structure according to claim 1, wherein the clamp extends over the coil spring.

4. The coil spring mounting structure according to claim 1, wherein the second bracket is mounted to the body of the shock absorber, the second bracket supporting the clamp that extends over the coil spring.

5. The coil spring mounting structure according to claim 1, wherein the aperture is configured to receive a portion of the coil spring.

6. The coil spring mounting structure according to claim 5, wherein the clamp extends over the bushing.

7. A coil spring mounting structure for a suspension strut, comprising:

a coil spring having a threaded portion;

a spring bracket fixed to a body of a shock absorber, the spring bracket having a coupling hole to receive the threaded portion of the coil spring;

at least one nut configured to secure the threaded portion of the coil spring to the spring bracket;

a second bracket mounted to the body of the shock absorber, the second bracket supporting a clamp that extends over the coil spring; and

at least one nut and at least one bolt that secures the clamp to the second bracket.

8. The coil spring mounting structure for a suspension strut according to claim 7,

wherein the clamp is mounted on the second bracket with a portion of the coil spring positioned between the clamp and the second bracket.

9. The coil spring mounting structure according to claim 7, further comprising a bushing having an aperture that is configured to receive a portion of the coil spring.

10. The coil spring mounting structure according to claim 9, wherein the clamp extends over the bushing.

11. A coil spring mounting structure for a suspension strut comprising:

a spring bracket secured to a shock-absorber, the spring bracket having a coupling hole;

a coil spring inserted into the coupling hole, the coil spring having screw threads formed on an end thereof;

nuts screw-coupled with the screw threads to fix the coil spring to the spring bracket;

a second bracket secured to the shock-absorber;

a clamp extending over a surface of the second bracket;

bolts and nuts securing the second bracket and the clamp; and

a bushing positioned between the clamp and the coil spring, said bushing having an aperture, said coil spring extending through the aperture.
