The specific embodiment

Below only with embodiment the embodiment that the present invention is possible being described, so is not the category that limits institute of the present invention wish protection, in advance statement.

Please refer to Fig. 1 to Fig. 3, the invention provides a kind of rope, comprise a body 10.This body 10 comprises one center rope yarn 11 and plural number and strand twines rope yarn, this center rope yarn 11 of those winding rope wire-wounds and around it, arranging, and those twine rope yarns and outwards sequentially are arranged as an internal layer, a middle level and a skin by this center rope yarn 11; Wherein, those twine rope yarn and comprise the first rope yarn 12, the second rope yarn 13 and the 3rd rope yarn 14, this first rope yarn 12 is identical with the sectional dimension of this second rope yarn 13, the sectional dimension of the 3rd rope yarn 14 is less than the sectional dimension of this first rope yarn 12 or this second rope yarn 13, this first rope yarn 12, the sectional dimension of this second rope yarn 13 and the 3rd rope yarn 14 is all less than the sectional dimension of this center rope yarn 11, this internal layer comprises six strand of first rope yarn 12, this middle level comprises 12 strand of second rope yarn 13, this skin comprises ten stereotyped writings the 3rd rope yarn 14, and those winding rope yarns are arranged in center rope yarn 11 and together twine around this center rope yarn 11 on every side.

In main embodiment of the present invention, center rope yarn 11 is all circle with the cross section that those twine rope yarn, and center rope yarn 11 twines rope yarn with those and all is made of metal, the preferably, the diameter of section ratio of center rope yarn 11, the first rope yarn 12, the second rope yarn 13 and the 3rd rope yarn 14 is about 23: 22: 22: 21, more accurate, in specific embodiments, the diameter of section of center rope yarn 11, the first rope yarn 12, the second rope yarn 13 and the 3rd rope yarn 14 is respectively 0.23mm, 0.22mm, 0.22mm and 0.21mm.

In addition, if see it with cross section, as shown in Figure 3, center rope yarn 11, each first rope yarn 12, wherein one second rope yarn 13 and wherein one the 3rd rope yarn 14 be a straight line and arrange, owing on average being arranged with six strand of first rope yarn 12 around the center rope yarn 11, center rope yarn 11 on the historical facts or anecdotes border, two strand of first rope yarn 12, two strand of second rope yarn 13 and two strand of the 3rd rope yarn 14 are a straight line and arrange, this seven strands line just in time is positioned on the diameter of this body and sequentially mutually supports, and then form connecting structure in the same plane, therefore body 10 is formed with three connecting structures altogether, this three connecting structures isogonism distributes and interlocks in center rope yarn 11 places, form a radial skeleton structure centered by center rope yarn 11 by this, remaining

second rope yarn

13 and 14 of the 3rd rope yarns are distributed between those connecting structures equably.

Because the pulling force on automobile-used transmission must be born axially with rope, and the rope of Multi-strand is less in the permission deflection axially, upwards there is larger permission deflection in the footpath because having the space between each strand line, therefore, during pulling force on the Multi-strand rope is subject to axially, the footpath makes progress inside contract situation can be stretcher strain on axially more easily occur, if radially inside contracting situation occurs, may instead cause the length of rope integral body to be elongated, yet, when rope is used for transmission, if changing, length may cause the error of transmission and control.And by radial skeleton structure of the present invention, body is in radially having several better supports, therefore being difficult for generation, body radially inside contracts phenomenon, even do not belong to the second rope yarn and the 3rd rope yarn of a radial skeleton structure part, also be difficult for interior compression deformation because of skeleton structure to outer support, body also just is difficult for producing axial length to be changed, therefore accurately pulling force transmission and control can be provided, and provide better structural strength by this skeleton structure, and the second rope yarn between skeleton structure and the 3rd rope yarn can be as the usefulness of buffering, unlikely too hard straight therefore body still can have crooking ability, be to have structural strength concurrently, the advantage of bent toughness and minimum length variations amount.

The above is preferred embodiment of the present invention and the know-why used thereof; for a person skilled in the art; in the situation that do not deviate from the spirit and scope of the present invention; any based on apparent changes such as the equivalent transformation on the technical solution of the present invention basis, simple replacements, all belong within the protection domain of the present invention.
