Description
One, technical field
The present invention relates to a kind of electric wire and method for making thereof, particularly a kind of vehicle anti-lock brake system thermoplastic elastomer sheath flexible cable and method for making thereof.
Two, technical background
Along with the raising of automobile driving speed, and the increase of road travel density, also just more and more higher to the ride safety of automobile performance demands, the antiskid control system of automobile produces under this requirement and grows up.Prevent that in braking procedure wheel is braked locking, avoid wheel to carry out slippage purely on the road surface, improve directional stability and the handling maneuver ability of automobile in braking procedure, the device that shortens braking distance is called as anti-blocking brake system, is called for short ABS.
Before nineteen seventies, anti-blocking brake system exists also that reaction speed is slow, control precision is low, be subject to defectives such as interference.Enter the seventies later stage, developing rapidly of digital electronic technology and large scale integrated circuit significantly improved the reaction speed and the control precision of system and device, is the universal rapidly condition of having created of anti-blocking brake system.
Because anti-blocking brake system obtains more prevalent approval to improving the ride safety of automobile performance, and the multiple anti-blocking brake system existing various informative, that price grade is different can be selected for the automobile of different class.So, having entered since the nineties, states such as Europe, the United States, day must possess anti-blocking brake system (ABS) with the car of new production and pickup truck and issue as rules.In China, Shanghai Volkswagen, FAW-Volkswagen, motor corporation such as general have also equipped anti-blocking brake system (ABS) device in succession on the sedan limousine of new production.
Anti-blocking brake system (ABS) device is a kind of new automobile braking system controller, at home, be mainly used in high-grade bus and car at present, its manufacture difficulty with relevant components and parts are had relatively high expectations, domestic still do not have manufacturing firm and produce, the whole dependence on import of all components and parts extensively adopt two-wheeled or four-wheel braking anti-lock braking system at present, and the cable that supporting with it transmission signals is used is monopolized the domestic market by the wire ﹠ cable factory of Germany basically.
Vehicle anti-lock brake system (ABS) is the flexible cable of a kind of connection car brake anti-lock braking system device (or claiming abs valve) and velocity transducer, is used for the transmission of signal.It requires cable to have low-temperature pliability, the anti-fatigability that circumnutates, vibration resistance, anti-corrosion, anti-slungshot bump and a performance such as fire-retardant.The cable that adopts general insulation and sheath material to produce can not satisfy so very harsh service condition, must be to the select redesign of cable from structure and material.
Three, summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of function admirable is provided, lasting serviceability temperature (3000h) is-40 ℃～125 ℃ vehicle anti-lock brake system thermoplastic elastomer sheath flexible cable and a method for making thereof.
For achieving the above object, vehicle anti-lock brake system of the present invention thermoplastic elastomer sheath flexible cable, be twisted into two strands of conductor wire cores (conductor) by many annealing circular copper wires, extrude the insulating barrier of making by the thermoplastic dynamic perduren material on the surface of per share conductor wire core, become insulated wire cores.The stranded stranding of two strand insulation cores extrudes one deck or two layers of sheath of being made by the TPUE material on the surface that becomes cable core.
The twisting pitch that many annealing circular copper wires are twisted into conductor is than being 12～16 times of this conductor diameter.
The thickness of insulating barrier is more than or equal to 0.24mm.
Two thoroughly do away with the stranded stranding of edge cores, and twisting pitch is than being not more than 9 times of stranding wire core diameter.
Restrictive coating closely is extruded in on the cable core, and fills up into the space between the cable core.
Vehicle anti-lock brake system of the present invention with the method for making of thermoplastic elastomer sheath flexible cable is: make conductor wire core with many copper single line strands, surface at conductor wire core extrudes into insulating barrier with the thermoplastic dynamic perduren material, with two stranded strandings of the insulated wire cores of making, extrude one deck or two layers of restrictive coating on the surface that becomes cable core with the TPUE material, be finished product.
Insulating barrier uses plastic extruder, extrusion temperature: 165 ± 5 ℃ of charging zones, 180 ± 5 ℃ on fuselage, 185 ± 5 ℃ of head die orifices.
Restrictive coating also uses plastic extruder, extrusion temperature: 150 ± 5 ℃ of charging zones, 160 ± 5 ℃ on fuselage, 155 ± 5 ℃ of head die orifices.
The present invention compared with prior art, its remarkable advantage is:
1, the lasting serviceability temperature of cable (3000 hours) is-40 ℃～+ 125 ℃.
2, under 50 ℃ of low temperature, cable has enough elasticity, mechanical strength; After low-temperature bending and low-temperature impact, cable insulation does not puncture.
3, when 150 ℃ of high temperature, cable is indeformable, do not shrink.
4, tear strength on average reaches 30N/mm; Shore hardness (A) 87.
5, stronger anti-impregnating agent, lubricant and FAM experimental liquid are arranged, sample is reeled and is not ftractureed after flooding; The external diameter expansion rate is less than 4%.
6, cable-flame retardant is good.
Four, description of drawings
Accompanying drawing is the structural representation of cable of the present invention.
