Abstract
The utility model belongs to a structural design of an abrasion resistance piston rod of a motor vehicle vibration absorber, which comprises a ceramlc thin film layer which is coated on a basis body layer of a chromium plating surface on a piston rod body or the ceramlc thin film layer which is directly coated on the piston rod body. The utility model has the advantages of abrasion resistance, long service life, easy operation and low manufacture cost.
Description
The utility model belongs to the piston lever of reducer for automobile technical field, relates in particular to the piston rod that is coated with wearing course.
Piston lever of reducer for automobile (or claim the automobile absorber connecting rod, and hereinafter to be referred as piston rod), be the crucial quick-wear part that directly influences automobile absorber performance and working life.In order to improve its wear resistance and reliability, piston rod adopts chromium plating usually and obtains the layer of surface base layer.But the wear resistance of this class piston rod is still unsatisfactory, and especially owing to aspects such as material and processing technologys, its wear resistance also far can not practical requirement.
The purpose of this utility model is to overcome the deficiency of prior art, and the structure of existing all kinds of piston rods is improved, and its wear resistance is strengthened, and improve working life, and it is simple also to have technology, advantage with low cost.
The wear-resistant piston rod of a kind of automobile absorber of the utility model design, its body surface has the chrome-plated surface base layer, it is characterized in that coated with ceramic film layer on the external cylindrical surface of said surface matrix layer.
The wear-resistant piston rod of another kind of automobile absorber of the present utility model is characterized in that, coated with ceramic film layer on the external cylindrical surface of said wear-resistant piston rod body.
Above-mentioned ceramic film can be by the single or multiple lift composite bed that pottery constituted of nitride, carbide, carboritride or the oxide of titanium, aluminium, zirconium, hafnium etc.The thickness of said every layer of ceramic film is 0.5-2.5 μ m.
First kind of wear-resistant piston rod that the utility model provides, owing to be on the wear-resistant surface base layer of existing piston rod, to have plated ceramic film again, therefore more wear-resisting, also more suitable.Directly plate second kind of piston rod of ceramic film on body, compare with aforementioned first kind of piston rod, its structure is simpler, and wear resistance is suitable.
Brief Description Of Drawings:
Fig. 1 is one of an embodiment of the present utility model construction profile.
Fig. 2 is embodiment's of the present utility model two construction profiles.
Fig. 3 is embodiment's of the present utility model three construction profiles.
The utility model is designed three kinds of wear-resistant piston rod embodiments, as Fig. 1～shown in Figure 3, is described below respectively in conjunction with each figure:
Embodiment 1, as shown in Figure 1.Comprise body 11, on the body external cylindrical surface, chrome-plated surface base layer 12 is arranged, on this base layer 12, be coated with one deck ceramic film 13 again.This ceramic film can adopt a kind of in the pottery of being made up of nitride, carbide, carboritride or the oxide of metals such as titanium, aluminium, zirconium, hafnium.
Present embodiment is that the wear resistance of the piston rod of original chromium plating base layer is improved, and further improves its working life.
Embodiment 2, as shown in Figure 2.Comprise body 21, on the body external cylindrical surface, directly be coated with one deck ceramic film 22, a kind of in this thin layer material material as described in example 1 above.
Present embodiment is compared with last embodiment, can make work simplification, reduces cost and antiwear property is suitable.
Embodiment 3, as shown in Figure 3.Comprise body 31, be coated with two layers of ceramic film on the body external cylindrical surface, wherein nexine 32 is the titanium carbide thin layer, and outer 33 is the titanium nitride thin rete.
Present embodiment has than aforementioned two kinds of better antiwear propertys of embodiment, thereby arranged longer working life.
Above-mentioned three kinds of embodiments' ceramic film all can adopt the mode of physical vapor deposition to obtain, and its each thicknesses of layers all can be 1.5 ± 0.5 μ m.
Claims (4)
1, the wear-resistant piston rod of a kind of automobile absorber, its body surface has the chrome-plated surface base layer, it is characterized in that coated with ceramic film layer on the external cylindrical surface of said surface matrix layer.
2, the wear-resistant piston rod of a kind of automobile absorber is characterized in that, coated with ceramic film layer on the external cylindrical surface of this body.
3, wear-resistant piston rod as claimed in claim 1 or 2 is characterized in that: said ceramic film is the single or multiple lift composite bed that pottery constituted by nitride, carbide, carboritride or the oxide of titanium, aluminium, zirconium, hafnium etc.
4, wear-resistant piston rod as claimed in claim 1 or 2, the thickness that it is characterized in that said each layer ceramic film are 0.5-2.5 μ m.
