Abstract
The utility model relates to a car brake hose structure, which comprises a rubber inner layer and a rubber outer layer, and is characterized in that a first braid and a second braid are arranged between the rubber inner layer and the rubber outer layer, wherein an isolated layer is arranged between the first and the second braids; and a bonding layer is arranged between the second braid and the rubber outer layer. The rubber inner layer is made of natural gum or ethylene propylene diene rubber, and the rubber outer layer is made of chloroprene rubber or ethylene propylene diene rubber. The braiding structure of the first braid adopts 2 or 3 shares of polyester thread, and the braid parameter of the polyester thread is 20 to 24 spindles. The braid structure of the second braid adopts 2 to 3shares of strong silk thread or vinylon thread, and the braid parameter of the strong silk thread or the vinylon thread is 20 to 24 spindles. The car brake hose structure can improve the technical properties of the car brake hose such as the hose adhesive attraction, high-low-temperature resistance, fatigue resistance, weather resistance, anti-aging property, braking resistance, tensile strengthand the like.
Description
Technical field
The utility model relates to automobile-used braking line system field, especially a kind of automobile brake hose construction that is applied on the automobile brake flexible pipe.
Background technique
Domestic automobile Brake hose structure is generally the structure of braid and rubber layer composition at present, braid all adopts identical polyester line, powerful silk thread and vinylon thread to make, the rubber internal layer adopts Nitrile Rubber and butadiene-styrene rubber, rubber outer adopts neoprene, though can satisfy the technical standard requirement of GB16897-97, but, require lower to high temperature resistant, endurance, assembly tensile strength and burst strength etc.And the U.S. of domestic production, Europe, Japan and main in the world motor corporation new listing new car, all adopt automobile brake flexible pipe new standard, its product is higher to the technical requirementss such as high-low temperature resistant, endurance, anti-dynamic pulse, Weather-resistant, low-expansion coefficient, sebific duct adhesion, assembly tensile strength and burst strength of Brake hose.The rubber material that at present domestic braid structure that generally adopts and rubber internal and external layer are adopted all can not satisfy the product requirement of automobile brake flexible pipe new standard.
Therefore, need a kind of automobile brake hose construction that adopts new structure and new material badly.
Summary of the invention
The purpose of this utility model is to improve performances such as the vapour sebific duct adhesion of Brake hose, high and low temperature resistance, fatigue performance, anti-weather-aging property, anti-braking ability, tensile strength, and a kind of automobile brake hose construction is provided.
Purpose of the present invention can reach by following measure:
A kind of automobile brake hose construction comprises being provided with first braid and second braid between rubber internal layer and rubber outer, described rubber internal layer and the rubber outer, is provided with separation layer between first braid and second braid; Be provided with bonding layer between second braid and the rubber outer.
The material of described rubber internal layer is natural gum or ethylene propylene diene rubber, and the material of outer layer rubber is neoprene or ethylene propylene diene rubber.
The material of described first braid is a polyester, and the material of the separation layer and second braid is silk or polyvinyl.
The polyester line that braiding structure adopted of described first braid is 2 strands or 3 strands, and the braiding parameter of polyester line is 20 ingot to 24 ingots.
The powerful silk thread that braiding structure adopted of described second braid or vinylon thread are 2 strands or 3 strands, and the braiding parameter of powerful silk thread or vinylon thread is 20 ingot to 24 ingots.
The invention has the beneficial effects as follows:
1, braid adopts new framework layer structure promptly to be made up of first braid and second braid, solve problems such as automobile brake hose attachment power is poor, endurance, tensile strength be not low, mentioned from 35 hours fatigue life greater than 70 hours, tensile strength and bringing up to more than the 2000N, adopt braiding structure that 20 ingots multiply by 20 ingots also to improve the manufacturing efficiency of Brake hose braid in addition from 1500N;
2, second braid adopts powerful silk thread or vinylon thread braiding to form, and to solve the bonding problem of rubber outer, adhesion is mentioned 15N/cm from 10N/cm;
3, rubber internal layer and rubber outer adopt the more rubber material of high-quality, solved that the automobile brake flexible pipe is high temperature resistant, low temperature resistant, the problem of resistance to braking fluid, anti-ozone difference, make that the automobile brake flexible pipe is high temperature resistant to be brought up to 120 ℃, resistance to low temperature from performance from 100 ℃ and drop to-57 ℃, resistance to braking fluid performance from-45 ℃ and bring up to 120 ℃, ozone resistance from 93 ℃ and bring up to 100ppm from 50ppm.
