Abstract
The utility model discloses a pipe fitting for an automobile power steering transmission system, which is characterized by comprising a copper-plated pipe substrate coating, a zinc-aluminum alloy coating and a chromium-plated coating in sequence from inside to outside; an aluminum-rich coating is arranged on the outer surface of the chromium-plated coating; the copper-plated pipe substrate layer is made of a copper-plated cold-rolled carbon steel belt; the thickness of the copper-plated pipe substrate coating is 0.7-1.2mm; the thicknesses of the zinc-aluminum alloy coating, the chromium-plated coating and the aluminum-rich coating are respectively 8-25 microns, 3-7 microns and 8-25 microns. The pipe fitting disclosed by the utility model has the characteristics of no harm to environment, long service life, good machining property and the like and is resistant to corrosion, which can reach more than 2000h through preliminary salt spray test.
Description
Technical field
The utility model relates to the pipe fitting that a kind of automobile power steering transmission system is used.
Background technique
Be applied in a kind of pipe fitting in the low side automobile power steering transmission system at present, be made up of steel pipe substrate layer and spelter coating, this pipe fitting from inside to outside is steel pipe substrate layer and spelter coating successively.When above-mentioned pipe fitting used in the automobile power steering transmission system, this pipe fitting was positioned at below the automobile chassis, is in a kind of exposed state.In long-term and air contact process, when especially running into sleety weather, pipe fitting can directly contact with rain or snow, and corrosion takes place long meeting of time one; Automobile is through the many road surface of uneven road surface or handstone the time, and the stone that splashes that wheel takes up is easy to coating is hit down, has a strong impact on the working life of pipe fitting, produces potential safety hazard.This shows that above-mentioned pipe fitting awaits further to improve.
The model utility content
The task of the utility model is to solve the technological deficiency that aforementioned pipe fitting exists in the existing technology, provides a kind of automobile power steering transmission system to use pipe fitting.
Its technical solution is:
A kind of automobile power steering transmission system is used pipe fitting, and above-mentioned pipe fitting is disposed with copper facing pipe substrate layer, zinc aluminum alloy coating and chrome plating from inside to outside, is provided with rich aluminium paint at the outer surface of chrome plating.
Above-mentioned copper facing pipe substrate layer adopts copper-plated cold-rolled carbon steel steel band to process.
The thickness of above-mentioned copper facing pipe substrate layer is 0.7～1.2 millimeter; The thickness of above-mentioned zinc aluminum alloy coating, chrome plating and rich aluminium paint is respectively 8～25 microns, 3～7 microns and 8～25 microns.
Above-mentioned chrome plating is a trivalent chromium coating.
The utlity model has following useful technique effect:
The utility model corrosion resistance is strong, can reach more than 2000 hours through preliminary salt spray test checking, has environmental sound, long service life, characteristics such as good processability.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Figure is the structural principle schematic representation of a kind of mode of execution of the utility model, is its cross-sectional configuration.
Embodiment
In conjunction with accompanying drawing, a kind of automobile power steering transmission system is used pipe fitting, and said pipe fitting is followed successively by copper facing pipe substrate layer 1, zinc aluminum alloy coating 2 and chrome plating 3 from inside to outside; Outer surface at chrome plating is provided with rich aluminium paint 4.
In the aforesaid way, chrome plating is preferably trivalent chromium coating.
In the aforesaid way, the thickness of copper facing substrate layer is 0.7～1.2 millimeter; The thickness of zinc aluminum alloy coating, trivalent chromium coating and rich aluminium paint is preferably 8～25 microns, 3～7 microns and 8～25 microns respectively.
In the aforesaid way, copper facing pipe substrate layer adopts copper-plated SPCC steel band system volume, promptly adopts copper-plated cold-rolled carbon steel steel band system volume; Be welded into tubing through soldering, this kind tubing corresponding tubing more of the prior art has good resistance to pressure; Corrosion resistance, mechanical property is outstanding.Zinc aluminum alloy coating adopts continuously electric gold-plated coating process to process, and has better adhesion, and when carrying out crooked experiment, difficult drop-off also has the effect that suitable resistance stone splashes.Rich aluminium paint has higher corrosion resistance and salt-tolerant trait.Adopt trivalent chromium coating as passivating layer, can not exert an influence, meet the ROSH standard environment.
The relevant technologies content of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
The utility model is mainly used in the automobile power transmission system, is extremely important part, and this system mainly is used for changing or keeps automobile running or fall back.In the existing technology, the automobile power steering system mainly is divided into hydraulic power steering system and electric boosting steering system, and the utility model is applied in the hydraulic power steering system.
Need to prove that those skilled in the art can also make such or such easy variation pattern under the instruction of this specification, such as equivalent way, or obvious mode of texturing.Above-mentioned variation pattern all should be within the protection domain of the utility model.
