Description
Technical field
The present invention relates to the lubricating oil path of VVT motor.
Background technique
Along with developing of automobile industry, more and more higher to Economy, the power character requirement of motor, so require also just more and more higher to the lubrication system of motor, so how to make lubricating oil path simple more, structure is compact more, and lubrication effect is better, is the difficult problem that we need break through.Be with the VVT engine oil gallery at present, basically be main oil gallery to be set in cylinder cap front end intermediate portion, this oil duct is in the water jacket outside and will guarantees certain wall thickness, so can increase the length 10-15mm of cylinder cap relatively, above the cylinder cap oil sump, be provided with two branch oil ducts then, this oil duct is very long to feed, the exhaust cam shaft fuel feeding, makes it and to divide oil duct to get through to guarantee it lubricated by the camshaft mounting hole processing inclined oil hole of air at each cylinder cap.This structure is not only complicated but also increase cylinder cap weight, increase shortcomings such as cost.The oil circuit that leads to phase discriminator is located on the cylinder cap basically.With the camshaft bearing on front end housing lid great majority are frame structures, promptly all are disjunctor between all bearing caps, and this complex structure, weight is big, cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of simple and compact for structure, effectively alleviate the lubricating oil path of the VVT motor of engine weight.
Realize the technological scheme of the object of the invention:
A kind of VVT engine oil gallery has cylinder cap, phase place solenoid valve, camshaft phaser, admission cam shaft, exhaust cam shaft, camshaft bearing lid, cam, tappet, valve, it is characterized in that:
Cylinder cap is provided with the main oil gallery that is connected with cylinder body, and this main oil gallery is the bolt hole of cylinder cap;
Cylinder cap also is provided with cylinder cap first auxiliary oil channel (8), the upright oil duct (10) of cylinder cap, and first camshaft bearing covers and is provided with bearing cap first auxiliary oil channel (11), and admission cam shaft auxiliary oil channel (12) is connected with bearing cap first auxiliary oil channel (11); The trend of oil circuit is followed successively by main oil gallery (6), cylinder cap first auxiliary oil channel (8), phase place solenoid valve oil duct (9), the upright oil duct (10) of cylinder cap, bearing cap first auxiliary oil channel (11), admission cam shaft auxiliary oil channel (12), camshaft phaser;
Cylinder cap also is provided with cylinder cap second auxiliary oil channel (7), first camshaft bearing and covers and be provided with bearing cap second auxiliary oil channel (13), admission cam shaft, exhaust cam shaft and be respectively arranged with camshaft main oil gallery (14,15), also is respectively arranged with camshaft and divides oil duct (16,17); The trend of oil circuit is followed successively by main oil gallery (6), cylinder cap second auxiliary oil channel (7), bearing cap second auxiliary oil channel (13), camshaft main oil gallery (14,15), camshaft and divides oil duct (16,17), camshaft and tappet and valve.
Camshaft is a hollow camshaft, and hollow space is the camshaft main oil gallery.
Each axle journal of camshaft all has the oilhole that links to each other with main oil gallery.
The clutch shaft bearing lid disjunctor setting of air inlet and exhaust cam shaft, all the other bearing caps are split settings.
The oil duct that first camshaft bearing covers all is to constitute by casting.
Make the relative big 1-1.5mm of all the other diameters of bolt hole of bolt hole of main oil gallery.
The beneficial effect that the present invention has:
Because cylinder cap main oil gallery and cylinder bolt hole integrate, and have effectively saved space (cylinder cap length can reduce 10-15mm), need not to set up oil circuit, reduce manufacturing procedure, and simpler on the structure, compact, alleviate engine weight, and guaranteed the Economy of product.
Convexity wheel shaft clutch shaft bearing lid of the present invention is conjuncted, the auxiliary oil circuit of phase discriminator is set on bearing cap, and also be provided with the auxiliary oil circuit of phase discriminator on the camshaft, two oil circuits link to each other, phase discriminator is contained in the camshaft front end, enter the auxiliary oil circuit of bearing cap by the auxiliary oil channel machine oil in the middle of the cylinder cap, enter camshaft phaser at the auxiliary oil circuit of the camshaft of flowing through.
The oil circuit of VVT was realized on cylinder cap basically in the past, and guarantee by processing, complicated oil circuit processing not only is not easy to guarantee, and cause complex structure on the cylinder cap, and influence the intensity of cylinder cap, and cause complex process, the cost height, and can take the space of cylinder cap, very big to the engine weight influence.Only need among the present invention above cylinder cap phase place solenoid valve oil circuit, be provided with two advance, spill port, regulate the work that the flow of machine oil comes the control phase device by the phase place solenoid valve.So the oil circuit on the cylinder cap is very simple, and realize easily, neither take the space of cylinder cap, and engine weight is not had influence.The oil circuit that leads to phase discriminator is integrated on camshaft clutch shaft bearing lid and the camshaft, with two that say previously advance, return and to be connected to form an effective oil circuit, and the auxiliary oil circuit on the bearing cap is to guarantee by casting, this structure has that structure is flexible, technology guarantees easily, and cost is low, whole oil circuit is very unobstructed, provides effective guarantee for lubricating.
