Abrasion-resistant shaft core protection pipe

Abstract

The invention discloses an abrasion-resistant shaft core protection pipe. The abrasion-resistant shaft core protection pipe comprises a pipe body. The inner wall of the pipe body is fixedly connectedwith a protection layer. The side, far away from the pipe body, of the protection layer is provided with a first plastic layer. The side, far away from the protection layer, of the first plastic layeris fixedly connected with a metal steel wire layer. The side, far away from the first plastic layer, of the metal steel wire layer is fixedly connected with a waterproof layer. According to the abrasion-resistant shaft core protection pipe, the protection pipe is internally and additionally provided with an abrasion-resistant layer made of a plastic material, a second plastic layer is made of a PE material, relatively high strength and tenacity are achieved, meanwhile, the abrasion-resistant layer is PEFE with a very small friction coefficient, the second plastic layer and the abrasion-resistant layer are in gapless fit, after the two kinds of plastic layers are coordinated, the strength of the abrasion-resistant shaft core protection pipe is guaranteed, the problem that the friction coefficient of a protection pipe is relatively high is solved well, meanwhile, the problems that the protection pipe is prone to breaking and is not resistant to abrasion, the service life of the protection pipe is shortened, and the using of the shaft core is affected are solved.

Description

technical field [0001] The invention relates to the technical field of protective tubes, in particular to a wear-resistant shaft core protective tube. Background technique [0002] In heavy-duty commercial vehicles, buses, trucks and other models, the shift shaft core is used to switch between different gears. A protective tube is set on the outer layer of the shift shaft core. When the shift shaft core is working, there is Friction, the current protective tube uses plastic to protect the shaft core. Due to the low strength of the plastic, the protective tube is easy to break and has no wear resistance, which reduces the service life of the protective tube and affects the use of the shaft core. Contents of the invention [0003] The purpose of the present invention is to provide a wear-resistant shaft core protection tube, which is not easy to break and has wear resistance, which increases the service life of the protection tube and facilitates the use of the shaft core, a...
