2. A camshaft front end cover as claimed in claim 1, wherein: and a reinforcing rib (3) is arranged between the other two screw holes (2).

Technical Field

The invention relates to a front end cover of a camshaft, and belongs to the technical field of automobile parts.

Background

The camshaft is as the important spare part of car, and the lubricated fuel feeding of camshaft front end housing need give VVT and camshaft simultaneously, has leaded to its own oil circuit too much then. Due to the fact that the number of the oil passages is too large, part of the oil passages can be perforated by the screw holes; once the oil way is perforated by the screw hole, the cleanliness of the oil way is difficult to ensure; simultaneously, when camshaft front end housing and cylinder head combination, the many oil circuits of camshaft front end housing can lead to the oil circuit on the cylinder cap also to increase, makes the structure of cylinder cap more complicated then.

Disclosure of Invention

In order to solve the problems in the background art, the invention provides a front end cover of a camshaft.

The invention adopts the following technical scheme: a front end cover of a camshaft comprises a front end cover body, wherein the front end cover body is provided with an oil groove, a front end cover oil way is arranged in the oil groove, and the front end cover oil way is communicated with a cylinder cover oil way of a cylinder cover; the front end cover body is provided with four screw holes used for being connected with the cylinder cover, wherein the screw holes are respectively positioned at two end parts of the oil groove, and the other two screw holes are positioned at the side of the oil groove.

Compared with the prior art, the invention has the beneficial effects that:

the invention has only one oil groove, so the structure is simpler; meanwhile, the front end cover oil way of the front end cover of the camshaft is communicated with the cylinder cover oil way of the cylinder cover, so that the complexity of the cylinder cover structure is reduced; through optimizing the oil circuit to the camshaft front end housing structure has been changed, camshaft front end housing and cylinder cap front end simple structure after the optimization, oil circuit quantity reduces, and the oil circuit is not perforated by the screw hole, practices thrift raw and other materials, has guaranteed the integrality of oil circuit and the cleanliness of machine oil.
