And when installing automobile gear shifting inhaul cable, automobile gear shifting inhaul cable usually will with other form touch, thus the wear damage of automobile gear shifting inhaul cable can be caused.In prior art, although have raw silk rings pipe to protect wire rope at the wire rope overcoat of automobile gear shifting inhaul cable, raw silk rings pipe also easy wear damage in movement process, does not therefore still well solve the wear damage problem of automobile gear shifting inhaul cable.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of automobile gear shifting inhaul cable with inside and outside two friction-reducing structure, to solve the fretting wear in prior art between wire rope and raw silk rings pipe and the fretting wear problem between raw silk rings pipe and other structure.
The automobile gear shifting inhaul cable of the inside and outside two friction-reducing structure of the utility model band, comprise wire rope and be enclosed within the raw silk rings pipe outside wire rope, described wire rope is evenly set side by side with engineering plastic pellet, and the inwall of described engineering plastic pellet and raw silk rings pipe is slidably matched;
Also comprise antifriction device, described antifriction device comprise ball, ring ballframe carriage and with ballframe carriage one is connected prop up otic placode, described otic placode is provided with mounting hole, annular cavity is provided with in described ballframe carriage, and the inner ring surface of ballframe carriage is provided with annular notches, described ball is disposed in parallel in annular cavity, and the spherical calotte of ball be positioned at annular notches outer and with the surface contact of raw silk rings pipe.
Further, arc-shaped spring piece ball being released annular notches is also provided with in described toroidal cavity.
Further, lubricating grease is provided with in described raw silk rings pipe.
Further, described raw silk rings pipe is the plastic tube of band female thread structure.
Further, described wire rope becomes spiral winding to form by two steel wires.
The beneficial effects of the utility model:
1, the automobile gear shifting inhaul cable of the inside and outside two friction-reducing structure of the utility model band, it is by arranging engineering plastic pellet on a steel cord, wire rope is separated with raw silk rings pipe by engineering plastic pellet, thus the friction that can reduce between wire rope and raw silk rings pipe, and the area of contact between engineering plastic pellet and raw silk rings pipe is little, frictional force is little, therefore can extend the working life of wire rope and raw silk rings pipe.
2, the automobile gear shifting inhaul cable of the inside and outside two friction-reducing structure of the utility model band, it by arranging antifriction device outside raw silk rings pipe, when automobile gear shifting inhaul cable need in installation process bending and with other form touch time, by antifriction device, gear-shifting inhaul cable is supported and fixed in other structure, due between raw silk rings pipe and antifriction device for rolling friction, thus the fretting wear of gear-shifting inhaul cable in movement process can be reduced greatly, be conducive to the working life of improving automobile gear shifting inhaul cable; Gear-shifting inhaul cable moves higher flexibly simultaneously, operates also more convenient laborsaving.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
As shown in the figure, the automobile gear shifting inhaul cable of the inside and outside two friction-reducing structure of the present embodiment band, the raw silk rings pipe 2 comprising wire rope 1 and be enclosed within outside wire rope, described wire rope is evenly set side by side with engineering plastic pellet 3, and the inwall of described engineering plastic pellet and raw silk rings pipe is slidably matched;
Also comprise antifriction device, described antifriction device comprise ball 4, ring ballframe carriage 5 and with ballframe carriage one is connected prop up otic placode 6, described otic placode is provided with mounting hole 7, annular cavity is provided with in described ballframe carriage, and the inner ring surface of ballframe carriage is provided with annular notches, described ball is disposed in parallel in annular cavity, and the spherical calotte of ball be positioned at annular notches outer and with the surface contact of raw silk rings pipe.
The automobile gear shifting inhaul cable of the inside and outside two friction-reducing structure of the present embodiment band, it is by arranging engineering plastic pellet on a steel cord, wire rope is separated with raw silk rings pipe by engineering plastic pellet, thus the friction that can reduce between wire rope and raw silk rings pipe, and the area of contact between engineering plastic pellet and raw silk rings pipe is little, frictional force is little, therefore can extend the working life of wire rope and raw silk rings pipe.
And the automobile gear shifting inhaul cable of the inside and outside two friction-reducing structure of the present embodiment band, it by arranging antifriction device outside raw silk rings pipe, when automobile gear shifting inhaul cable need in installation process bending and with other form touch time, by antifriction device, gear-shifting inhaul cable is supported and fixed in other structure, due between raw silk rings pipe and antifriction device for rolling friction, thus the fretting wear of gear-shifting inhaul cable in movement process can be reduced greatly, be conducive to the working life of improving automobile gear shifting inhaul cable; Gear-shifting inhaul cable moves higher flexibly simultaneously, operates also more convenient laborsaving.
