However, the side rod acting in the transverse direction on the piston rod is generated due to the difference in the force action direction of the spring 2 and the force direction in which the vehicle load acts as a strut, and only the small diameter circular protrusion 2a There is also a problem in that the direction bearing force is weak so that the spring 3 and the pad 2 are easily separated from the lower seat 1.

To solve some of these problems, a urethane hose is inserted between the lower end of the spring and the lower seat to prevent direct contact between the foreign material and the spring. However, the urethane hose is not a fundamental solution, but also has a disadvantage of inevitable material cost increase of 1,600 won per vehicle.

On the other hand, as another conventional technique for preventing contact between the spring and the foreign matter, by applying a step to the end side of the lower seat on which the spring is seated, the foreign matter is deposited below the step, thereby preventing contact between the spring and the foreign matter.

In addition, as another conventional technique, a part of the pad on which the spring is seated is cut and removed from the pad covered on the upper surface of the lower seat to block contact between the spring and the foreign matter.

However, the above-described prior arts have some effects in preventing foreign matter from penetrating, but stress concentration may occur at the pad stepped portion or the end portion, and thus, the pad and the lower seat may be easily damaged.

The present invention has been made to solve the conventional problems as described above, to provide a spring support mechanism of a vehicle suspension for preventing the foreign matter flow between the spring and the pad is always in close contact with the spring and the pad.

Another object of the present invention is to provide a spring support mechanism of a vehicle suspension that relieves stress concentration by a spring by changing the shape of a pad end.

Still another object of the present invention is to provide a spring support mechanism of a vehicle suspension for preventing the separation of the pad and the spring by increasing the torsional support of the spring.

It may be characterized in that it comprises a; pad to fill the space is always in close contact with the bottom of the spring.

Here, the end portion of the finish portion may be formed to be inclined downward gradually from the top to the bottom is formed in the upper end in close contact with the spring longer than the lower portion is extended in the upward direction of the spring.

In addition, the end portion of the finish portion may be formed to be inclined downward by a predetermined length from the top to the lower end of the upper end is extended in the longer direction of the spring than the lower end portion thereof.

In addition, an elastic hole having a shape that is opened outward at the end of the finishing portion may be formed in the transverse direction.

In addition, the finish upper surface may be formed to be inclined upward along the lower end of the spring.

In addition, the finish surface may be formed in a planar shape.

In addition, a plurality of square grooves are formed in the lower seat, and a plurality of square protrusions may protrude from the bottom of the pad so as to correspond to the square grooves.

In addition, a stopper protrusion may protrude upward from the lower seat to support an end of the spring.

The present invention through the above-described problem solving means, the finish is formed in the space formed between the rising portion of the spring and the lower seat, the closing portion is formed along the rising portion of the spring, as well as during full bump of the vehicle In the pulley bounce, the bottom of the spring is in close contact with the upper surface of the finish portion to block foreign matter from flowing between the spring and the pad, thereby preventing the spring from being broken.

In addition, since the end portion of the finishing portion is formed to be inclined to one side or the elastic hole is formed, the freedom of deformation in the vertical direction is also increased, thereby reducing stress concentration in the pad and the lower seat by the spring, thereby increasing the rigidity and durability of the component. There is also an effect.

In addition, the upper surface of the finish portion is formed in a flat bar without the inner diameter of the spring is restrained bar, there is an advantage that the design of the lower end of the spring can be made freely.

In addition, since the pad is coupled to the lower seat through the coupling configuration of the square protrusion and the square groove, and the stopper protrusion is supported at the end of the spring, the pad and the spring are separated from the lower seat by increasing the lateral support when the side load is applied. It also has the effect of preventing.
