Wire for vehicle and method for preparing outer sleeve body of wire for vehicle

Abstract

The invention provides a wire for a vehicle and a method for preparing an outer sleeve body of the wire for the vehicle. The wire for the vehicle comprises a center line body, a middle sleeve body, the outer sleeve body and a color layer, wherein the middle sleeve body is sleeved on the center line body, and the middle sleeve body and the center line body can relatively axially slide; the outer sleeve body is sleeved on the middle sleeve body, and at least one part of the color layer is covered on the outer surface of the outer sleeve body; the color layer and the part of the outer sleeve body uncovered through the color layer reveals the exterior. The method for preparing the outer sleeve body of the wire for the vehicle comprises the following steps of: (a), providing the outer sleeve body which is formed by a long strip piece in a continuous spiral manner, wherein the outer sleeve body is provided with multiple spiral coil sections; (b) forming the color layer, wherein at least one part of the color layer is covered on the outer surface of the outer sleeve body, and the color layer and the part of the outer sleeve body uncovered through the color layer reveals the exterior. The wire for the vehicle provided by the invention has the advantages that the wire is functional and beautiful and durable, and the cost is low. The method provided by the invention has the advantages that the method is simple and rapid, and the cost is low.

Description

technical field [0001] The invention relates to a wire body, in particular to a wire for a vehicle and a method for preparing an outer body of the wire for a vehicle. Background technique [0002] The wiring used for braking and shifting on a general vehicle such as a bicycle or a motorcycle is a cable made of a plurality of wires. The cable is provided with a conduit for substantially the entire length of the cable, which is actuated by the brake handle or the shift handle. This cable controls brake or transmission actuation. [0003] Most of the conventional cables are twisted and rolled, which has a twisted outer surface. In order to strengthen the protection of the cables, a plurality of coating layers are usually tightly wrapped on the outside of the cables in order to reduce the number of the cables. Friction with the inner surface of the conduit to avoid wear and damage to the cable after prolonged contact and friction. Although this structure is covered with many c...

AI Technical Summary

Problems solved by technology

Although this structure is covered with many coatings to prevent the cables from directly rubbing against the inner surface of the conduit, the coatings move simultaneously with the cables, which cannot reduce the friction between the coatings and the inner surface of the conduit. The friction between the surfaces, so after long-term contact friction, the coating will still be worn and damaged, and the service life is also short and often needs to be replaced

In addition, most cladding layers not only require more structural materials, but also the manufacturing process is more complicated and difficult, and the manufacturing cost is also higher

[0004] Furthermore, the inner surfaces of such conventional wires and coatings, as well as coatings and wire conduits, will produce great frictional resistance, which is not conducive to braking action and control, and after long-term contact friction, the Cables wear out and often need to be replaced

In addition, after a period of use, it is easy to cause the cable to be damp and rusted due to the infiltration of rainwater or the accumulation of dust, which will reduce the service life
