Inhaul cable sleeve for automobile

Abstract

The embodiment of the invention discloses an inhaul cable sleeve for an automobile. The inhaul cable sleeve comprises a corrugated lining tube, a flat steel belt, a steel wire layer and a plastic coating layer in turn from inside to outside, wherein the corrugated lining tube has a hollow tubular structure; the inner surface of the corrugated lining tube is the surface with continuous corrugated bulges; the flat steel belt has a flat banded structure; the flat steel belt is spirally wound on the outer surface of the corrugated lining tube; a bare tube of the inhaul cable sleeve for the automobile is formed by the flat steel belt and the corrugated lining tube; the steel wire layer is composed of a plurality of steel wires; the steel wires in the steel wire layer are uniformly distributed on the outer surface of the bare tube; and the plastic coating layer covers the outermost layer of the tubular structure formed by the corrugated lining tube, the flat steel belt and the steel wire layer. By adopting the inhaul cable sleeve for the automobile provided by the invention, a contact area of a lining tube and a steel wire rope is reduced, and a frictional force caused by the relative motion of the lining tube and the steel wire rope, namely, an operating force during the working process of an inhaul cable of the automobile, is reduced, so that the force-transferring efficiency of the inhaul cable of the automobile is increased and the noise caused by the vibration of the steel wire rope and the lining tube is reduced.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an automobile cable casing. Background technique [0002] The automobile cable sleeve is an important component used in the automobile control cable. As a component to protect the internal parts of the automobile cable and transmit the steering force, it plays an extremely important role in the performance of the automobile cable. As the core component of the automobile cable casing, the inner liner is directly matched with the automobile cable (wire rope) parts that transmit the steering force, so the structure and performance of the automobile cable casing also directly affect the operation of the automobile cable performance. [0003] But, in the automotive cable bushing that is used in the market at present, its cable lining pipe all is the smooth structure of inner and outer wall, is conventional circular tube (such as figure 1 shown). This makes the product in the bending working ...

AI Technical Summary

Problems solved by technology

This makes the product in the bending working state in actual application, the steel wire rope and the inner liner have a larger contact area, resulting in greater friction, which increases the required operating force and reduces the efficiency of the product's force transmission. At the same time, noise will be generated due to the vibration between the wire rope and the inner liner. These factors limit the operation feel and performance of the automobile cable
