Abstract
The utility model discloses the structure of an automobile idler shaft. The idler shaft comprises an idler shaft body and a wear-resistant layer attached to the outer side of the idler shaft body, wherein the idler shaft body comprises a shaft body and an eccentric shaft wheel formed integrally with the shaft body; a spherical pit is formed in the shaft body; an elastic gasket is fixed on the inner wall of the spherical pit. According to the structure of the automobile idler shaft, the idler shaft is sprayed with the wear-resistant layer with a good wear-resistant effect, so that the wear resistance of the idler shaft is effectively improved, the service life of the idler shaft is prolonged, and the safety in use is ensured; the spherical pit matched with a positioning ball is also designed, and the elastic gasket is attached to the inner wall of the pit, so that wear influence on the positioning ball and the inner wall of the pit is avoided, and the safety in use is further improved.
Description
Technical field
The utility model relates to a kind of automobile idler shaft structure, especially a kind of automotive reverse gear idler shaft structure.
Background technique
Automotive transmission is in the time of assembling, reverse idler gear is arranged on reverse idler gear axle, reverse idler gear axle and case of transmission are fixed, reverse idler gear axle top is provided with reverse idler gear axle bolt hole, case of transmission top is provided with bolt of transmission case hole, when assembling, reverse idler gear axle bolt hole must be aimed at bolt of transmission case hole, reverse idler gear axle fixing bolt could be penetrated and is tightened.And this reverse idler gear axle is under the state working long hours, very easily there is serious wear, and then the reduction of Security while causing using, shorten the working life of reverse idler gear axle simultaneously.
Thus, the inventor considers existing automobile idler shaft structure to improve, and this case produces thus.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of automobile idler shaft structure, and it utilizes spraying abrasion-proof to damage layer increases its abrasion resistance properties, and then extends its working life.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of automobile idler shaft structure, this idler shaft comprises idler shaft body and is attached to the anti abrasion layer in idler shaft body outside; Described idler shaft body comprises an axis body and the integrated eccentric arbor wheel of axis body, is provided with a spherical pit, and is fixed with elastic insert on this spherical pit inwall on described axis body.
Further, described eccentric arbor wheel is ellipticity, and is provided with idler shaft bolt hole on this eccentric shaft.
Further, the central point of described spherical shrinkage pool is positioned on the axis of described axis body.
Further, described anti abrasion layer comprises the protective layer of the noncrystal Kohlenstoffgehalt that form or that have cubic crystalline form combination by the noncrystal carbon of cubic crystalline form combination and the adhesion tie layer with titanium between described idler shaft body and protective layer.
Further, the thickness of described adhesion tie layer is 40nm to 100nm.
Further, the bed thickness of described protective layer is 2 μ m to 5 μ m.
Further, described resilient pad is the arc pad matching with spherical pit shape, and this resilient pad comprises by the packed layer of outer field metal coating and internal layer and forming.
Further, the material of described metal coating is any one in stainless steel, nickel, titanium, copper, iron, aluminium or lead.
Further, the material of described packed layer is any one in graphite, teflon, asbestos or pottery.
Further, described resilient pad thickness is 0.3mm-0.8mm.
The utility model sprays a side anti abrasion layer on idler shaft, and this anti abrasion layer has good wear-resistant effect, and then makes this its wear-resistant degree of novel effective raising, thereby extends its working life, guarantees Security in use; On the other hand, this novel spherical pit coordinating with place kick that also designed, and adhere to resilient pad on this pit inwall, and guarantee the not frayed impact of place kick and pit inwall, further improve its safety in utilization.
