Abstract
The utility model discloses an engine camshaft lubricating oil passage structure. Two camshaft bearings caps at the intake side and the exhaust side are integrated with two rockshaft bearing seats into a whole body; a main oil passage 1 is arranged in each camshaft bearing cap, and is communicated with the first camshaft bearing cap 4 through an oil hole 3 on a bolt hole 2, communicated with the first rockshaft bearing seat 6 through a bolt hole 5, communicated with the second rockshaft bearing seat 10 through a bolt hole 9 and communicated with the second camshaft bearing cap 12 through an oil hole 11 on the bolt hole 9. The utility model has the advantages of saving the arrangement of the camshaft lubricating oil passage arranged on an engine cylinder head, reducing the machining difficulties and cost of the engine cylinder head and facilitating the arrangement of the camshaft lubricating oil passage.
Description
Technical field:
The utility model belongs to technical field of engines, relates in particular to a kind of engine cam lubricating fitting.
Background technique:
The oil leab of general engine cam all is that design is on cylinder cap, guarantee that all camshaft bearing journals surface of matching with bearing cap and cylinder cap obtains sufficient lubrication and cooling, especially cylinder cap inside will cast air flue and water jacket, so the complex structure of cylinder cap, the lubricating oil for machining channel ratio is difficult on cylinder cap.Cylinder cap processing technology complexity, cost height.
Summary of the invention:
The purpose of this utility model provides a kind of reduction engine cylinder cover difficulty of processing and cost, the engine cam lubricating fitting that makes things convenient for the camshaft lubrication oil circuit to arrange.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of engine cam lubricating fitting, two camshaft-bearing caps of inlet and outlet side and two pitman arm shaft bearing supports are one, one main oil gallery 1 is arranged in the camshaft-bearing cap, main oil gallery 1 by the oilhole 3 on the bolt hole 2 is communicated with first camshaft-bearing cap 4, main oil gallery 1 by bolt hole 5 be communicated with the first pitman arm shaft bearing support 6, main oil gallery 1 passes through the oilhole 11 that bolt hole 9 is communicated with the second pitman arm shaft bearing support 10, main oil gallery 1 passes through on the bolt hole 9 and is communicated with second camshaft-bearing cap 12.
The further technological scheme of the utility model is, described pitman arm shaft axis is provided with central oil passage 13, be provided with pitman arm shaft axle journal oilhole 8 with the rocking arm axis normal with the contacted axle journal of pitman arm shaft bearing support, the two ends of oilhole 8 communicate with camshaft central oil passage 13 with perpendicular to the oil duct 7 of main oil gallery 1 respectively.
The lubricant oil that comes from cylinder body directly arrives oil duct 1, by 3 lubricated first camshaft-bearing caps 4 of the oilhole on the bolt hole 2 of vertical oil duct 1, the bolt hole 5 lubricated first pitman arm shaft bearing supports 6 by vertical oil duct 1, other has the oilhole 8 on the oil duct 7 of a vertical oil duct 1 to lead to the first pitman arm shaft bearing support 6, by the bolt hole 9 lubricated second pitman arm shaft bearing supports 10 of vertical oil duct 1, oilhole 11 lubricated second camshaft-bearing caps 12 on the bolt hole 9.
Thereby the oil that arrives oilhole 8 places of the first pitman arm shaft bearing support 6 enters oilhole 14 lubricated rocker bearings by oil duct 13.
The beneficial effects of the utility model are the layouts that engine cylinder covered save the camshaft lubrication oil circuit, reduce engine cylinder cover difficulty of processing and cost, make things convenient for the camshaft lubrication oil circuit to arrange.
Description of drawings:

Fig. 2 is a pitman arm shaft lubricant oil road structure schematic representation.
Among the figure: the 1-oil duct 2-bolt hole 3-oilhole 4-first camshaft-bearing cap 5-bolt hole 6-first pitman arm shaft bearing support 7-oil duct 8-oilhole 9-bolt hole 10-second pitman arm shaft bearing support 11-oilhole 12-second camshaft-bearing cap 13-oil duct 14-oilhole
Embodiment:
As shown in Figure 1, two camshaft-bearing caps of inlet and outlet side and two pitman arm shaft bearing supports are one, one main oil gallery 1 is arranged in the camshaft-bearing cap, main oil gallery 1 by the oilhole 3 on the bolt hole 2 is communicated with first camshaft-bearing cap 4, main oil gallery 1 by bolt hole 5 be communicated with the first pitman arm shaft bearing support 6, main oil gallery 1 passes through the oilhole 11 that bolt hole 9 is communicated with the second pitman arm shaft bearing support 10, main oil gallery 1 passes through on the bolt hole 9 and is communicated with second camshaft-bearing cap 12; In conjunction with shown in Figure 2; axis are provided with central oil passage 13 in the pitman arm shaft bearing support 6; be provided with pitman arm shaft axle journal oilhole 8 with the rocking arm axis normal with pitman arm shaft bearing support 6 contacted axle journals, the two ends of oilhole 8 communicate with camshaft central oil passage 13 with perpendicular to the oil duct 7 of main oil gallery 1 respectively.
Referring to shown in Figure 1, the lubricant oil that comes from cylinder body directly arrives oil duct 1, by 3 lubricated first camshaft-bearing caps 4 of the oilhole on the bolt hole 2 of vertical oil duct 1, the bolt hole 5 lubricated first pitman arm shaft bearing supports 6 by vertical oil duct 1, other has the oilhole 8 on the oil duct 7 of a vertical oil duct 1 to lead to the first pitman arm shaft bearing support 6, by the bolt hole 9 lubricated second pitman arm shaft bearing supports 10 of vertical oil duct 1, oilhole 11 lubricated second camshaft-bearing caps 12 on the bolt hole 9.
Shown in accompanying drawing 2, thereby the oil that arrives oilhole 8 places of the first pitman arm shaft bearing support 6 enters oilhole 14 lubricated rocker bearings by oil duct 13.
