Abstract

The utility model relates to a two-layer coating-plastic steel wire rope with high sealing property for a control pull rope assembly in the automobile industry; and the steel wire rope is formed by close composition of five layers such as a central steel wire (1), an inner-layer steel wire (2), an inner-layer coating layer (3), an outer-layer steel wire (4) and an outer-layer coating layer (5) from inside to outside in sequence. The two-layer coating-plastic steel wire rope can better improve the sealing property of a product, enhance the corrosion resistance of the product and prolong the service life.

Description

The double-deck plastic coated wire ropes of high leakproofness

(1) technical field

The utility model relates to a kind of steel wire rope.The control inhaul cable assembly that is used for automobile industry.

(2) background technology

In automobile industry, the control inhaul cable assembly that essential needs the are relevant use that matches.As throttle inhaul cable assembly, gear shift pulling cable assembly, brake line assembly etc.Common control cord assembly drag-line is generally common outer surface plastic coated wire ropes series of products such as (as Fig. 1).

Common outer surface plastic coated wire ropes all has certain interval between cover wire and internal layer thigh steel wire twisting, and internal lubrication oil also easily runs off, the inner wire easy-to-rust.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of sealing that can improve product well is provided, and strengthens the product anticorrosive property, the double-deck plastic coated wire ropes of the high leakproofness that increases the service life.

The purpose of this utility model is achieved in that the double-deck plastic coated wire ropes of a kind of high leakproofness, from the inside to the outside successively by core wire, steel wire of internal layer, internal layer clad, cover wire and outer cladding layer totally five layers closely be composited.

The beneficial effects of the utility model are:

1, whole approximate pole of steel wire rope, stayed surface is big, and the pressure that bears on the unit are during use is less, and stress distribution is even, long service life.

2, the surface of steel wire of internal layer and cover wire all smoothly seals, and the empty G﹠W of outside is difficult for infiltrating steel wire of internal layer or whole steel wire rope inside, and the also difficult loss of internal lubrication oil, can prevent the corrosion of inner wire.This heart yearn wherein has one one to expose in air in subsequent installation, and the bifilar steel cable of double-deck plastic-coated can better prevent corrosion.

3, the adjacent layer steel wire is twisted with the fingers on the contrary, has good not rotatory, and the lay pitch is big, and structural stretch is little.

4, select the double-deck plastic coated wire ropes of high leakproofness, can effectively reduce the noise of braking.

(4) description of drawings

Fig. 1 is the section structure schematic diagram of common in the past outer surface plastic coated wire ropes.

Fig. 2 is the section structure schematic diagram of the double-deck plastic coated wire ropes of the utility model high leakproofness.

Reference numeral among the figure:

Core wire 1, steel wire of internal layer 2, internal layer clad 3, cover wire 4, outer cladding layer 5.

(5) specific embodiment

Referring to Fig. 2, Fig. 2 is the section structure schematic diagram of the double-deck plastic coated wire ropes of the utility model high leakproofness.As seen from Figure 2, the double-deck plastic coated wire ropes of the utility model high leakproofness, from the inside to the outside successively by core wire 1, steel wire of internal layer 2, internal layer clad 3, cover wire 4 and outer cladding layer 5 totally five layers closely be composited.

Its twisting technology summary:

The twisting technology of the double-deck plastic coated wire ropes of high leakproofness divided for four steps:

The twisting (1*7) of the first step, wire rope core circle thigh, this rope strand twisting with ordinary steel rope is identical.

Second step, coat one deck plastics twisting with the fingers on the good wire rope core circle strand, identical with the technology of common plastic coated wire ropes.

The 3rd step, on the circle that coats strand, the twisting layer of steel wire becomes the 1*19 rope again.The method of twisting steel wire floor is identical with the twisting ordinary steel rope.But this twisting steel wire floor should be made very high compactness, and is not loose, to obtain steel wire rope surface smoothing and good sealing property.

The 4th step, the outer one deck plastics that coat again of 1*19 rope.

Claims

1. the double-deck plastic coated wire ropes of a high leakproofness, it is characterized in that described steel wire rope from the inside to the outside successively by core wire (1), steel wire of internal layer (2), internal layer clad (3), cover wire (4) and outer cladding layer (5) totally five layers closely be composited.
