Problems solved by technology

[0002] The traditional automotive coil spring seat is mainly assembled by the welding assembly of the upper spring seat of the car body. Since the coil spring seat is a cylindrical structure, it is difficult to assemble the spring seat and the car body.
After a period of use, it is easy to loosen due to the deformation of the spring seat
At the same time, because the car is in motion, when the suspension is in the working condition of the maximum rebound, the pre-pressure of the coil spring and the upper seat of the body spring becomes smaller, so that the spring and the spring seat do not fit well, and there is a problem with the spring seat when the suspension recovers. Larger shocks aggravate damage to the spring seat

Embodiment Construction

[0011] see figure 1 , this helical spring seat adopts natural rubber molding to form, is a revolving body, and the center is an open taper hole 3, assembles with the vehicle body spring upper seat. The taper hole 3 structure of about 20° is adopted, and four spherical bosses 2 with a radius of 1.5 mm are distributed on the conical wall surface of the taper hole 3 to cooperate with the spring upper seat of the vehicle body. The diameter of the cone bottom of the taper hole 3 is Φ50.5±0.3mm, and the diameter of the cone mouth is Φ46±0.3mm. The fit with the body is an interference fit. The distance between the spherical boss 2 and the end surface of the cone bottom of the taper hole is 10mm. on the circumference of the cone. When assembled with the spring seat of the vehicle body, the reliability of cooperation can be improved, and the movement of the spring seat relative to the vehicle body during vehicle movement can be reduced.

Abstract

The invention provides an automotive helical spring seat, which is a rotating body made of rubber. The automotive helical spring seat is assembled with an automotive body spring upper base through a tapered bore, and a helical spring is assembled through a helical spring seat base body. A middle hole is a tapered hole which is in interference fit with the automotive body spring seat; spherical lug bosses which are matched with the automotive body are distributed on a hole wall of the tapered hole close to the middle position; an arc groove is formed on the helical spring seat base body for assembling the helical spring; and the radius of the arc groove is smaller than the radius of the spring wire of the assembled helical spring, and the arc groove is in interference fit with the spring. The helical spring seat can meet the requirements of assembly and use of the helical spring through the tapered hole and the spherical lug bosses on the surface of the tapered hole, and can guarantee that the spring seat cannot loosen during use. By designing the helical spring seat base body and the spring assembling position into an arc groove binding face, the compressive deformation motion of the spring in the spring motion is limited, the noise in the automobile motion is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to an automobile coil spring seat. Background technique [0002] The traditional automotive coil spring seat is assembled mainly by the welding assembly of the upper spring seat of the vehicle body. Since the coil spring seat is a cylindrical structure, it is difficult to assemble the spring seat and the vehicle body. After a period of use, it is easy to loosen due to the deformation of the spring seat. At the same time, because the car is in motion, when the suspension is in the working condition of maximum rebound, the pre-pressure of the coil spring and the upper seat of the body spring becomes smaller, so that the spring and the spring seat do not fit well, and there is a problem with the spring seat when the suspension recovers. Larger impacts aggravate the damage to the spring seat. Contents of the invention [0003] The object of the present invention is to provide a helical spring seat structure with simple structure, ...
