Technical field
The utility model belongs to camshaft technical field, and in particular to a kind of automobile camshaft.
Background technology
Camshaft is a component in piston engine, its effect is to control unlatching and the closed action of valve, though
So in four-stroke engine the rotating speed of camshaft be bent axle half（The rotating speed and bent axle of camshaft in two stroke engine
It is identical）, but usually its rotating speed is still very high, and needs to bear very big moment of torsion, thus in designing to camshaft strong
Requirement in terms of degree and support is very high, its material is usually superior alloy steel or steel alloy；Since valve motion rule is related to
The power and service performance of one engine, thus camshaft design in the design process of engine in occupation of highly important
Status.
But traditional automobile camshaft includes axis body and the admission cam being integrally disposed upon on the axis body and is vented convex
Wheel, since using integrated design, the angle angle between admission cam and exhaust cam can not be adjusted, if needing
Adjust, then can only replace whole camshaft, and any one component is damaged and is required for integral replacing；Secondly, camshaft exists
In the course of work, admission cam, the exhaust cam of camshaft are directly contacted with tappet bottom, what cam and tappet were obtained by splashing
Lubricating oil, ensures lubrication between the two, can be due to that the relative sliding velocity between cam and tappet working face is very high, camshaft
Cam and tappet lack of lubrication, radiating condition is poor, causes tappet bottom surface to wear, influences the transmission of cam and tappet.
Utility model content
The purpose of this utility model is to provide a kind of automobile camshaft, to solve tradition proposed in the above background technology
Automobile camshaft include axis body and the admission cam and exhaust cam that are integrally disposed upon on the axis body, due to using one
Bodyization designs, therefore can not adjust the angle angle between admission cam and exhaust cam, if desired adjusts, then can only replace
Whole camshaft, and any one component is damaged and is required for integral replacing；Secondly, camshaft during the work time, camshaft
Admission cam, exhaust cam directly contacted with tappet bottom, the lubricating oil that cam and tappet are obtained by splashing, ensures both it
Between lubrication, can be due to that the relative sliding velocity between cam and tappet working face is very high, the cam of camshaft and tappet lubricate not
Foot, radiating condition is poor, the problem of causing tappet bottom surface to wear, influence the transmission of cam and tappet.
To achieve the above object, the utility model provides following technical solution：A kind of automobile camshaft, including axis body, institute
