Abstract
The utility model discloses a camshaft, which comprises a cam and a shaft body. The cam is connected with the shaft body in a close fitting way; and the shaft body has a hollow type structure, and an inner hole is a through hole. Preferably, the shaft body is formed at one time by a cast steel material. Preferably, the exterior of the cross section of the shaft body has an oval structure; and the inner hole has a circular structure. The camshaft has the beneficial effects that the material is saved; the required accuracy of parts is not high; processing is convenient; the shaft body has the hollow structure, so an oil pipe is not needed, and the hole of the shaft body is taken as the oil pipe; and the camshaft has a simple structure and is very practical.
Description
Technical field
The utility model belongs to automotive field, particularly the camshaft on motor car engine.
Background technique
Existing camshaft axis body is all generally solid, and its materials'use amount is large, and cost of production is high, and difficult processing, and operation is loaded down with trivial details.
The model utility content
For the deficiencies in the prior art, the utility model provides a kind of camshaft.
To achieve these goals, technical solution adopted in the utility model is:
A kind of camshaft comprises cam and axis body, and cam is connected with the axis body close-fitting, and described axis body is the hollow type structure, and endoporus is through hole.
As preferably, described axis body adopts cast steel once-through structure.
As preferably, described axis body cross section outside is oval, and endoporus is round structure.
The beneficial effects of the utility model: the utility model has namely been saved material, and the part precision prescribed is not high, easily processing, and axis body selects hollow structure not need separately to establish oil pipe, the axis body hole can be used as oil pipe, and this new structure is simply very practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
A kind of camshaft as shown in Figure 1 comprises cam 1 and axis body 2, and cam 1 is connected with axis body 2 close-fittings, and described axis body 2 is the hollow type structure, and endoporus 3 is through hole.Described axis body 2 adopts cast steel once-through structure.Described axis body cross section outside is that oval endoporus 3 is round structure.
The utility model has namely been saved material, and the part precision prescribed is not high, easily processing, and axis body 2 selects hollow structure not need separately to establish oil pipe, axis body endoporus 3 can be used as oil pipe, and this new structure is simply very practical.
Be more than the utility model preferred forms, in related domain, those skilled in the art's simple change and replacement are all within protection domain of the present utility model.
