Problems solved by technology

[0006] However, in the case of forming the coating material of the coil spring through such a process, not only the productivity is lowered, but also when the adhesive is not uniformly coated, the coil spring and the coating material are partially separated, resulting in Problems such as peeling off of the coating material of the partitioned part

Abstract

A vehicle suspension thermally shrinkable tube of the present invention is provided in a shape corresponding to a vehicle-suspension coil spring having a spiral shape and is formed so as to have a larger diameter than the diameter of the spring so as to allow the spring to be coupled by insertion; and is formed from a material the volume of which shrinks upon applying heat when the spring is coupled by insertion; and, after the spring has been slotted in and coupled, heat is applied and said tube is made to attach intimately to the spring.

Description

technical field [0001] The present invention relates to a tube (tube) inserted / bonded to the surface of a spring used in an automobile suspension device, and more specifically, relates to the manufacture of a heat-shrinkable tube in which the material of the above-mentioned tube is heat-shrinkable and a spiral-shaped tube can be produced using a mold A device and a method for manufacturing a heat-shrinkable tube using the device. Background technique [0002] Generally, in a passenger car, a coil spring (coil spring) of a coil shape is used for a suspension device to absorb shocks generated when the vehicle is driven, protect the vehicle body, and maintain a comfortable ride for the occupants. Recently, since coil springs are installed in the body of most passenger cars, research on this is very active. If such a coil spring is used as a suspension device, although the riding experience can be improved compared with a vehicle using a leaf spring, there are still some struct...
