Abstract

The utility model relates to a travel cable, which comprises a travel cable steel wire and a travel cable sleeve pipe covered outside the travel cable steel wire, wherein the travel cable steel wire can slide in the travel cable sleeve pipe and comprises a steel wire iron core arranged at the inner side, a steel wire layer formed by arranging thick and thin steel wires at intervals is covered on the outer circumferential surface of the steel wire iron core, and a flat winding wire is wound outside the steel wire layer. The travel cable has the beneficial effects that both the travel cable steel wire and the travel cable sleeve pipe have higher mechanical intensity, the safe use of the travel cable can be ensured, the steel wire layer with the thick and thin steel wires arranged at intervals is covered on the outer circumferential surface of the steel wire iron core, and lubricating oil can be conveniently stored into the steel wire layer of the travel cable steel wire, so the friction force generated when the travel cable steel wire slides in the travel cable sleeve pipe is reduced, the service life of the travel cable is prolonged, the reliability and the sensitivity of the long-distance operation and control are ensured, meanwhile, the flat winding wire is wound outside the steel wire layer, and the push-pull effect of the travel cable is realized.

Description

A kind of drag-line

(1) technical field

The utility model relates to auto parts and components, relates in particular to a kind of drag-line that is used on the automobile.

(2) background technique

In automobile industry, the control inhaul cable assembly that essential needs are relevant uses that match is as throttle inhaul cable assembly, shift gears inhaul cable assembly, brake line assembly etc.Common control inhaul cable assembly generally is made up of the wire rope shell flexible pipe outer with being sleeved on wire rope, and wire rope can slippage in the shell flexible pipe.The control inhaul cable assembly is when work, wire rope slippage in the shell flexible pipe, because wire rope contacts with the inwall of shell flexible pipe and has surface friction drag, thereby make between wire rope and the shell flexible pipe and produce abrasion deformation, cause the control inhaul cable assembly short working life, the operation resistance is big, has reduced the reliability and the sensitivity of remote control.

(3) summary of the invention

Have above-mentioned deficiency in the prior art in order to overcome, the utility model provides a kind of simple in structure, long service life, reliability and the high drag-line of sensitivity.

The technical scheme in the invention for solving the technical problem is: a kind of drag-line, comprise the drag-line steel wire and be coated on the outer cable sleeve of this drag-line steel wire, described drag-line steel wire can slide in described cable sleeve, described drag-line steel wire comprises the steel wire iron core that is arranged on inside, be enclosed with by thick, finer wire on the outer peripheral surface of this steel wire iron core and be spaced the steel wire floor that forms, this steel wire floor is wound with flat coiling outward.

Further, the oblique compartment of terrain of described coiling is wrapped in outside the described steel wire floor, and the angle at 45 with the axis of described drag-line steel wire, makes the better effects if that pushes away, draws active force of the present utility model.

Further, described cable sleeve comprises and is sleeved on the outer metal sleeve of described drag-line steel wire and is wrapped in the outer rubber leather hose of this metal sleeve, makes cable sleeve have suitable mechanical strength, effectively the drag-line steel wire is protected.

The beneficial effects of the utility model are: drag-line steel wire and cable sleeve all have bigger mechanical strength, can guarantee the safe handling of drag-line, owing to be enclosed with the spaced steel wire floor of thickness on the outer peripheral surface of steel wire iron core, be convenient in the steel wire floor that lubricant oil is stored in the drag-line steel wire, thereby reduced the frictional force when the drag-line steel wire slides in cable sleeve, prolong working life of the present utility model, guaranteed the reliability and the sensitivity of remote control.Simultaneously, steel wire floor is wound with flat coiling outward, realizes the effect that pushes away, draws of the present utility model.

(4) description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a schematic cross-section of the present utility model.

(5) embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

With reference to Fig. 1, Fig. 2, a kind of drag-line, comprise the drag-line steel wire and be coated on the outer cable sleeve of this drag-line steel wire, described drag-line steel wire can slide in described cable sleeve, described drag-line steel wire comprises the steel wire iron core 1 that is arranged on inside, be enclosed with on the outer peripheral surface of this steel wire iron core 1 by thick, finer wire and be spaced the steel wire floor 2 that forms, be wound with flat coiling 3 outside this steel wire floor 2.Make drag-line steel wire and cable sleeve all have bigger mechanical strength like this, can guarantee the safe handling of drag-line, owing to be enclosed with the spaced steel wire floor 2 of thickness on the outer peripheral surface of steel wire iron core 1, be convenient in the steel wire floor 2 that lubricant oil is stored in the drag-line steel wire, thereby reduced the frictional force when the drag-line steel wire slides in cable sleeve, prolong working life of the present utility model, guaranteed the reliability and the sensitivity of remote control.Simultaneously, be wound with flat coiling 3 outside the steel wire floor 2, realize the effect that pushes away, draws of the present utility model.

Described coiling 3 oblique compartment of terrains are wrapped in outside the described steel wire floor 2, and the angle at 45 with the axis of described drag-line steel wire, make the better effects if that pushes away, draws active force of the present utility model.

Described cable sleeve comprises and is sleeved on the outer metal sleeve 4 of described drag-line steel wire and is wrapped in the outer rubber leather hose 5 of this metal sleeve 4, makes cable sleeve have suitable mechanical strength, effectively the drag-line steel wire is protected.
