Abstract
The utility model discloses a novel engine camshaft. An engine oil channel is disposed on an engine camshaft. The engine oil channel comprises a main oil channel extending along the direction of the camshaft and a secondary oil channel disposed on the camshaft neck. The secondary oil channel is communicated with the main oil channel and the outer surface of the camshaft neck. A VVT phaser is disposed at the end portion of the camshaft near a first camshaft neck. The main oil channel is communicated with the oil channel of the VVT phaser. The secondary oil channel on the first camshaft neck is communicated with an oil groove on a first bearing cover. Lubricating oil enters the main oil channel through the secondary oil channel of the first camshaft neck. A part of the lubricating oil outflows through other the secondary oil channels of camshaft necks for lubrication, and the other part flows in the oil channel of the VVT phaser, supplying oil for the VVT phaser. The novel engine camshaft is advantageous in that the oil supply of the VVT phaser and the self-lubrication of the camshaft are both satisfied; with simple and compact structure and light weight, the camshaft reduces the processing difficulty, decreases producing cost and engine cost, and greatly improves the cost performance of an engine.
Description
Technical field
The utility model belongs to the technical field of vehicular engine, and specifically, the utility model relates to a kind of novel engine camshaft.
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, timing sprocket through a minute oil circuit, returns oil sump by oil circuit again.Because working loads such as camshaft, camshaft bearing journal are bigger, so all adopt the pressure lubrication mode, this just need be provided with oil leab for the engine cam lubricating structure.
At present, the camshaft lubrication structure all is that oil leab is set on cylinder cap, forms oil passage, and the surface that the axle journal of all camshafts matches with bearing cap is carried out lubricating fully.Because the inside of cylinder cap will cast water jacket and air flue, can cause the cylinder cap complex structure again, the processing and lubrication oil duct is relatively difficult on cylinder cap.
In order to improve engine power performance, reduce the oil consumption of automobile, generally all on motor, increase the VVT technology now, and the VVT controller need be controlled by machine oil, the realization of this oil circuit must lean on camshaft to realize.
The model utility content
Technical problem to be solved in the utility model is a kind of novel engine camshaft, its objective is to realize utilizing the optimization of the oil circuit of camshaft for VVT phase discriminator fuel feeding and realization camshaft lubrication oil channel structures.
In order to solve the problems of the technologies described above, the technological scheme that the utility model adopted is: a kind of novel engine camshaft, be fixed on the cylinder head by a plurality of bearing caps, first axle journal of camshaft is located at its end, cooperate with the clutch shaft bearing lid, be provided with the machine oil oil duct on camshaft, described oil duct comprises along camshaft and extends axially the main oil gallery of setting and be arranged on secondary oil duct on the camshaft bearing journal that this pair oil duct is communicated with main oil gallery and axle journal outer surface; The VVT phase discriminator is arranged on described camshaft end, and near described camshaft first axle journal, described main oil gallery is communicated with the oil duct of described VVT phase discriminator.
Described camshaft is full supporting type camshaft, is provided with secondary oil duct on its each axle journal.
Secondary oil duct on described camshaft first axle journal is connected with the oil groove that described clutch shaft bearing covers.
Establish the bearing cap holding down bolt on the described bearing cap, realize the location of bearing cap and engine cylinder cap and be fastenedly connected by this bolt.
The utility model adopts technique scheme, is optimized by the lubricating oil path to engine cam, has both satisfied the fuel feeding of VVT phase discriminator, has guaranteed the lubricated of camshaft self again; This camshaft structure is simple, compact, has reduced the volumetric spaces of motor, and weight reduction reduces the mechanical processing technique difficulty; And air cylinder head structure becomes simple, and reduces its casting and difficulty of processing, and its assembly quality also is reduced; Employing can be saved the motor cost through the camshaft of this optimization, improves the cost performance of motor greatly.
Description of drawings
Fig. 1 is the utility model structural representation;
Mark among the above-mentioned figure is: 1, camshaft; 2, axle journal; 3, secondary oil duct; 4, VVT phase discriminator; 5, main oil gallery.
Embodiment
As shown in Figure 1, a kind of novel engine camshaft of the utility model, be fixed on the cylinder head by a plurality of bearing caps, first axle journal of camshaft 1 is located at its end, cooperate with the clutch shaft bearing lid, be provided with the machine oil oil duct on camshaft 1, described oil duct comprises along camshaft 1 and extends axially the main oil gallery 5 of setting and be arranged on secondary oil duct 3 on the camshaft bearing journal 2 that this pair oil duct 3 is communicated with main oil gallery 5 and axle journal 2 outer surfaces; VVT phase discriminator 4 is arranged on described camshaft 1 end, and near described camshaft first axle journal, described main oil gallery 5 is communicated with the oil duct of described VVT phase discriminator 4.This camshaft 1 is full supporting type camshaft, is provided with secondary oil duct 3 on its each axle journal 2.Secondary oil duct 3 on first axle journal of this camshaft 1 is connected with the oil groove that described clutch shaft bearing covers, lubricant oil enters camshaft main oil gallery 5 through the secondary oil duct 3 of cylinder head, clutch shaft bearing lid, camshaft first axle journal, a part flows out through the secondary oil duct on all the other each axle journals 23 again, be lubricated, another part flows into the oil duct of VVT phase discriminator 4, gives VVT phase discriminator 4 fuel feeding.
On bearing cap, establish the bearing cap holding down bolt, realize the location of bearing cap and engine cylinder cap and be fastenedly connected by this bolt.
Adopt technique scheme, be optimized, both satisfied the fuel feeding of VVT phase discriminator 4, guaranteed the lubricated of camshaft 1 self again by lubricating oil path to engine cam 1; This camshaft 1 is simple in structure, compact, has reduced the volumetric spaces of motor, and weight reduction reduces the mechanical processing technique difficulty; And air cylinder head structure becomes simple, and reduces its casting and difficulty of processing, and its assembly quality also is reduced; Employing can be saved the motor cost through the camshaft 1 of this optimization, improves the cost performance of motor greatly.
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 adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
