Abstract
The utility model provides a novel cam shaft, belongs to and the engine technology field. It provides a novel cam shaft, and it can be realized an oil circuit hole and give the purpose of phaser fuel feeding and the lubricated fuel feeding of camshaft simultaneously, save space. It includes the cam axis body, the internal center department of camshaft is equipped with oil pocket and moist sliding chamber along the axial, be equipped with on the wall of camshaft side with the communicating inlet port of oil pocket, the internal center department of camshaft is equipped with with the oil pocket and moistens the communicating orifice of sliding chamber, the oil pocket is used for for the phaser fuel feeding, moist sliding chamber is used for for the camshaft fuel feeding, is used for lubricatedly the axle journal of camshaft. The utility model discloses can realize an oil circuit hole and give the purpose of phaser fuel feeding and the lubricated fuel feeding of camshaft simultaneously, compact structure saves space.
Description
Technical field
The utility model relates to technical field of engines, particularly relates to a kind of camshaft.
Background technology
At present, VVT type engine cam lubricated and separate to cam phaser fuel feeding oilhole, need to arrange two oil ducts on cylinder cap, by the different oilhole oil-feeds on camshaft journal, an oilhole is to phaser fuel feeding, after another oilhole oil-feed, by oil pressure, by lubricating oil, the oil circuit hole from camshaft journal squeezes out, and reaches the object of lubricated other axle journal, so arranges, need cylinder cap to have enough spaces to arrange two oil ducts, be unfavorable for the compact design of cylinder cap.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of Novel camshaft, and it can realize an oil circuit hole simultaneously to the object of phaser fuel feeding and camshaft lubrication fuel feeding, saves space.
Technical solution adopted in the utility model is: a kind of Novel camshaft, it comprises cam axis body, in described cam axis body, center is provided with oil pocket and lubricating cavity vertically, camshaft body sidewall is provided with the fuel feed hole communicating with described oil pocket, in cam axis body, center is provided with the throttle orifice communicating with oil pocket and lubricating cavity, and described oil pocket is used for to phaser fuel feeding; Lubricating cavity is used for to camshaft fuel feeding, for the axle journal of lubricated described camshaft.
The beneficial effects of the utility model are:
1. camshaft body sidewall is provided with the fuel feed hole communicating with described oil pocket, in cam axis body, center is provided with the throttle orifice communicating with oil pocket and lubricating cavity, by this oil circuit, the utility model can be realized an oil circuit hole simultaneously to the object of phaser fuel feeding and camshaft lubrication fuel feeding.
2. described in, the diameter of throttle orifice is less than the diameter of lubricating cavity, can play throttling action.
3. the utility model has been realized and in less space, has been passed through an oil circuit hole simultaneously to the object of phaser fuel feeding and camshaft lubrication fuel feeding, and compact conformation, saves space.
Brief description of the drawings
Fig. 1: the axial cutaway view of the utility model;
Wherein: 1-fuel feed hole; 2-throttle orifice; 3-lubricating cavity; 4-cam axis body; 5-oil pocket.
Detailed description of the invention
As shown in Figure 1, a kind of Novel camshaft, it comprises cam axis body 4, the interior center of described cam axis body 4 is provided with oil pocket 5 and lubricating cavity 3 vertically, cam axis body 4 sidewalls are provided with the fuel feed hole 1 communicating with described oil pocket 5, the interior center of cam axis body 4 is provided with the throttle orifice 2 communicating with oil pocket 5 and lubricating cavity 3, and described oil pocket 5 is for giving phaser fuel feeding; Lubricating cavity 3 is for giving camshaft fuel feeding, for the axle journal of lubricated described camshaft.
The diameter of described throttle orifice 2 is less than the diameter of lubricating cavity 3, and the diameter of described lubricating cavity 3 is less than the diameter of oil pocket 5. Its effect is: throttle orifice 2 apertures are little, can play the effect of throttling.
