The technical solution adopted in the present invention is: the split type housing construction of a kind of engine multi-oil channel, comprise cylinder block, crankcase and bearing cap, cylinder block is connected by the straight pin location and by bolt with crankcase, crankcase is connected by seam location and bolt with bearing cap, cylinder block is the block-head cylinder body structure, include distribution tappet chamber, cylinder-bore and water cavity, the three adopts the cast inblock mode to be connected formation mutually; Crankcase is located by the terminal A of the cylinder-bore lower support plane that bolton is connected cylinder block, and crankcase left and right sides sidewall employing planer type structure, is sunken under the main bearing hole down; The bearing cap structure is the monomer suspension type, and a plurality of bearing caps mutually combine with crankcase side by side and form vertical many grades of main bearing holes, single bearing cap is connected with crankcase 6 Main bearing bolts of employing with about respectively 2 horizontal bolts that draw are in addition fastening; Design has three vertical oil ducts to be respectively secondary oil duct, distribution auxiliary oil channel and cooling jet fuel feeding oil duct on the cylinder block, secondary oil duct is positioned at cylinder-bore lower-left side, the distribution auxiliary oil channel is positioned at upper left side, distribution tappet chamber, and cooling jet fuel feeding oil duct is positioned at the cylinder-bore right lower side; Each vertical oil duct can add deep hole drill by machine to be realized; 5 of branch's oil duct single cylinder designs on the cylinder block, lead to different friction pairs by the distribution auxiliary oil channel respectively, distribution rocker shaft hole comprising tappet hole, monoblock pump hole and cylinder head top, except that secondary oil duct need be with the crankcase oil duct be communicated with at the flywheel end, other vertical oil duct ports utilize the screw plug sealing, be furnished with the main oil gallery that aims at the main bearing hole fuel feeding on the crankcase, it is positioned at the main bearing hole upper right side, and main oil gallery utilizes the screw plug sealing in the corresponding opposite side of flywheel casing end aperture.
Beneficial effect of the present invention: each absolute construction volume of this split type body is little, and casting manufacturability is good, and material selectivity is big.Arrange distribution tappet chamber and cylinder-bore in the cylinder block, by structural change, the distribution device and the cylinder liner that are fit to multiple pattern are installed, and crankcase can repeated application.
This structure body adopts cylinder block and crankcase to make up mutually, and connecting link is few; Bolt length is little, and rigidity is big; Overall structure rigidity is big.Cylinder head and cylinder block make up separately, and bolt arrangement is not influenced by split type housing construction, cylinder seal reliability height.
Cylinder block and crankcase are arranged many oil circuits, and have one's own work to do, the whole linking, have good lubricated and cooling effect, and the phase mutual interference is little.
Description of drawings
The present invention has 2 width of cloth accompanying drawings, and wherein Fig. 1 is a most preferred embodiment of the present invention, also can make the accompanying drawing of specification digest.
