Abstract
This utility model relates to a kind of brake hard tube, and including brake hard tube body, the outer surface at brake hard tube body is provided with anticorrosive coat；It is outside equipped with PCV overcoat at anticorrosive coat；PCV overcoat outer surface is provided with PA overcoat；PA overcoat outer surface is provided with PP overcoat；PP overcoat outer surface is provided with EPDM overcoat.The application, by arranging PCV overcoat, PA overcoat, PP overcoat and EPDM overcoat at brake hard tube body outer surface, can effectively prevent the impact of hard thing and effectively completely cut off the erosion to brake hard tube body such as salt fog, silt；And designed by the structure of EPDM overcoat, it is possible to effectively avoid the stone impact to PP overcoat；Use the difference of the coefficient of elasticity of unlike material overcoat simultaneously, significantly reduce the vibration of brake hard tube.
Description
Technical field
This utility model belongs to brakes technical field, particularly relates to a kind of brake hard tube.
Background technology
Passenger car mostly is hydraulic braking at present, is transmitted brake fluid by air-brake coupling hose and brake hard tube in brakes loop.
Because of brake hard tube be positioned at car body with low bottom-disc at, therefore to anticorrosion and resistance to stone impact etc. require higher.Meanwhile, along with car load
The raising that NVH requires, the vibrations delivery request between associated components the most gradually receives publicity.
Being illustrated in figure 1 prior art passenger car brake hard tube sectional view, brake hard tube is three-decker, and brake hard tube is originally
Body 01 is the double-deck butt-welded tube, and the outer surface at brake hard tube body 01 is provided with zinc coat 02 for anticorrosion；At zinc coat
02 is outside equipped with PCV (polrvinyl chloride) layer 03 protects.
Its decay resistance of existing brake hard tube is on the weak side, is only above 1000h, and protective layer is more weak by stone impact capacity,
If its Corrosion Protection will drastically decline after protective layer ruptures.It is that walking at brake hard tube upwards increases for these conventional safeguard procedures
Plastic protective plate, plastic protective plate cost is high, volume big, and brings chassis whole height to reduce, and affects car load air flowing etc. unfavorable
Factor.It addition, because brake hard tube is installed along vehicle body sheet metal, the vibration of brake hard tube can pass to vehicle body, reduce comfortableness.
Utility model content
The purpose of this utility model is to provide a kind of brake hard tube, needs poor with the antiseptic power of the existing brake hard tube of solution
Individually safeguard procedures and the problem of damping difference.
This utility model is achieved through the following technical solutions:
A kind of brake hard tube, including brake hard tube body, the outer surface at described brake hard tube body is provided with anticorrosive coat；
It is outside equipped with PCV overcoat at described anticorrosive coat；Described PCV overcoat outer surface is provided with PA overcoat；
Described PA overcoat outer surface is provided with PP overcoat；Described PP overcoat outer surface is provided with EPDM protection
Layer.
Described PA overcoat is identical with the thickness of described PP overcoat.
Described PA overcoat is all higher than 25 microns with the thickness of described PP overcoat.
Outer surface at described EPDM overcoat is provided with v-depression along the axis direction of described brake hard tube body.
Described v-depression totally eight.
The outer surface of the radial cross-section of described EPDM overcoat is in positive anistree star.
The beneficial effects of the utility model are:
The application is anti-by arranging PCV overcoat, PA overcoat, PP overcoat and EPDM at brake hard tube body outer surface
Sheath, can effectively prevent the impact of hard thing and effectively completely cut off the erosion to brake hard tube body such as salt fog, silt；And pass through
The structure design of EPDM overcoat, it is possible to effectively avoid the stone impact to PP overcoat；Use unlike material protection simultaneously
The difference of the coefficient of elasticity of layer, significantly reduces the vibration of brake hard tube.

Detailed description of the invention
Describing the technical solution of the utility model by the following examples in detail, below example is only exemplary
, it is only capable of for explaining and illustrate the technical solution of the utility model, and is not to be construed as technical solutions of the utility model
Restriction.
The application provides a kind of brake hard tube, as in figure 2 it is shown, include brake hard tube body, in this application, brake hard tube
Body 1 is prior art, generally uses the double-deck butt-welded tube；Outer surface at described brake hard tube body 1 is provided with anticorrosive coat
2, in this application, anticorrosive coat is prior art, still uses zinc coat for anticorrosion；It is outside equipped with at described anticorrosive coat 2
PCV overcoat 3, PCV overcoat 3 is also prior art；Described PCV overcoat 3 outer surface is provided with PA (nylon) overcoat
4；In this application, the thickness of PA overcoat 4 is more than 25 microns.
Described PA overcoat 4 outer surface is provided with PP (polypropylene) overcoat 5；Set at described PP overcoat 5 outer surface
It is equipped with EPDM (ethylene propylene diene rubber) overcoat 6.
Described PA overcoat is identical with the thickness of described PP overcoat.Described PA overcoat and the thickness of described PP overcoat
It is all higher than 25 microns, but less than the thickness of PCV overcoat.
Outer surface at described EPDM overcoat is provided with eight v-depressions along the axis direction of described brake hard tube body.
The outer surface of the radial cross-section of described EPDM overcoat is in positive anistree star.Angle between the most adjacent two angles is 45
Degree.
Use the difference of the coefficient of elasticity of unlike material overcoat, significantly reduce the vibration of brake hard tube.
The above is only the description of preferred implementation of utility model, it is noted that limited due to literal expression
Property, and objectively there is unlimited concrete structure, for those skilled in the art, without departing from this reality
On the premise of new principle, it is also possible to make some improvements and modifications, these improvements and modifications also should be regarded as this utility model
Protection domain.
