Abstract
The utility model discloses an automobile engine camshaft lubricating structure, wherein a journal of the camshaft (8) is mounted between a camshaft bearing cap (6) and a cylinder head (7); the camshaft bearing cap (6) is on the inner circle surface in contact with the cylinder head (7) and the journal of the camshaft (8), and a groove-shaped lubricant passage (9) is provided on the circumference. Compared to the prior art, the utility model reduces the processing difficulty of the engine cylinder head and the weight of the camshaft provided the camshaft is fully lubricated.
Description
Technical field
The utility model relates to automobile chassis, and more particularly, the utility model relates to a kind of camshaft of car engine lubricating structure.
Background technique
In the lubrication system of motor car engine, the parts of lubricating oil in the main oil gallery is led to camshaft bearing, cam, positive hour wheel through a minute oil circuit, returns oil sump from positive hour wheel through oil circuit again.Because the working load of camshaft, main journal, crank pin etc. is bigger, so all adopt the mode of lubrication pressure hydrodynamic lubrication, this just need be provided with oil leab at the engine cam lubricating structure.
At present, the camshaft lubrication structure all is to establish oil leab on cylinder cap, makes lubricant oil form lubricated path, carries out the surface that all axle journals and bearing cap, axle journal match with cylinder cap lubricated fully.Because the inside of cylinder cap will cast water jacket and air-casing, so the complex structure of cylinder cap, the processing and lubrication oil circuit is relatively more difficult on cylinder cap.
The model utility content
Problem to be solved in the utility model provides a kind of camshaft of car engine lubricating structure, its objective is the difficulty of processing that reduces engine cylinder cover.
To achieve these goals, technical solution adopted in the utility model is: on this camshaft of car engine lubricating structure, the axle journal of camshaft is installed between camshaft-bearing cap and the cylinder cap, described camshaft-bearing cap with the contacted surface of the axle journal of cylinder cap and camshaft on, along the circumferential direction be provided with the oil leab of groove shaped.
Described oil leab is established the admission cam shaft oil leab on the intake cam shaft neck attachment face on the camshaft, on exhaust cam shaft neck attachment face, establish the exhaust cam shaft oil leab, with surface that cylinder cap (7) contacts on establish in the middle of oil duct, and admission cam shaft oil leab and exhaust cam shaft oil leab are connected by middle oil duct.
Establish camshaft center oilhole on the described camshaft axis, on the contacted axle journal of itself and camshaft-bearing cap, establish the camshaft bearing journal oilhole vertical with the camshaft axis, this hole is connected on the axle journal outer surface with oil leab that camshaft bearing covers, innerly connects with camshaft center oilhole.
The utility model adopts technique scheme compared with prior art, fully guaranteeing to have reduced the difficulty of processing of engine cylinder cover under the lubricated prerequisite of camshaft, has alleviated the weight of camshaft.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of camshaft-bearing cap shown in Figure 1.
Number in the figure is: 1, intake cam shaft neck attachment face, 2, exhaust cam shaft neck attachment face, 3, the admission cam shaft oil leab, 4, middle oil duct, 5, the exhaust cam shaft oil leab, 6, camshaft-bearing cap, 7, cylinder cap, 8, camshaft, 9, oil leab, 10, camshaft center oilhole, 11, camshaft bearing journal oilhole, 12, cam, 13, the camshaft-bearing cap mounting hole, 14, the bearing cap attachment face.
Embodiment
Shown in the structural representation of the camshaft-bearing cap of the structural representation of the present utility model of Fig. 1 and Fig. 2, the utility model is a kind of camshaft of car engine lubricating structure, axle journal at this structure convexity wheel shaft 8 is installed between camshaft-bearing cap 6 and the cylinder cap 7, by being contained in the clamping bolt in the camshaft-bearing cap mounting hole 13, camshaft-bearing cap 6 is fastened on the cylinder cap 7, and bearing cap attachment face 14 connects with cylinder cap 7.Can rotate after camshaft 8 is installed, and pass through the motion that cam 12 promotes valves, guarantee that each cylinder inlet and exhaust valve in time opens and closes by certain order of work and port timing.The camshaft lubrication structure guarantees between the axle journal and camshaft-bearing cap 6 of camshaft 8, lubricate fully when high-speed motion between the axle journal of camshaft 8 and the cylinder cap 7, to reduce wear and to reduce temperature.
The utility model considers that the inside of engine cylinder cover 7 will cast water jacket and air-casing, its structure more complicated, and technology is a processing and lubrication oil duct on engine cylinder cover 7 at present, it is very difficult to add man-hour like this.Therefore, technical conceive of the present utility model is that oil leab is changed on the camshaft-bearing cap easy to process relatively 6, and structurally takes corresponding measure.Its embodiment is as follows:
Camshaft-bearing cap 6 with the contacted internal circular surfaces of axle journal of cylinder cap 7 and camshaft 8 on, along the circumferential direction be provided with the oil leab 9 of groove shaped.
Oil leab 9 is to establish admission cam shaft oil leab 3 on the intake cam shaft neck attachment face 1 on the camshaft 8, on exhaust cam shaft neck attachment face 2, establish exhaust cam shaft oil leab 5, with surface that cylinder cap 7 contacts on establish in the middle of oil duct 4, and admission cam shaft oil leab 3 and exhaust cam shaft oil leab 5 are connected by middle oil duct 4.
Establish camshaft center oilhole 10 on camshaft 8 axis, on itself and camshaft-bearing cap 6 contacted axle journals, establish camshaft bearing journal oilhole 11 with camshaft 8 axis normal, this hole is being connected with oil leab 9 on the camshaft-bearing cap 6 on the axle journal outer surface, innerly connects with camshaft center oilhole 10.
After taking aforesaid way, the utility model has alleviated the weight of camshaft fully guaranteeing to have reduced the difficulty of processing of engine cylinder cover under the lubricated prerequisite of camshaft.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technological scheme to carry out; or directly apply to other occasion without improvement, all within protection domain of the present utility model.
