Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3 shows, the automobile engine of the present invention, including the oil sump 4 bottom cylinder body 1, cylinder cap 11 and cylinder body 1, the oil duct 2 communicated with oil sump 4 it is provided with in cylinder body 1, being provided with lubricating oil pump 3 with oil sump 4 on the passage that oil duct 2 communicates, described oil duct 2 is interconnected to constitute by oil pipe.By oil duct 2 is made with oil pipe, make to be effectively improved the sealing property of oil duct 2, prevent from revealing, meanwhile, after oil duct 2 is made with oil pipe, engine cylinder-body operation in subsequent mechanical is processed can be greatly reduced, shorten the manufacturing cycle, as used oil pipe to be connected with each other as oil duct, the machining of oblique oil duct 5 can be cancelled, for the opening of the purposes such as sand removal, it is greatly shortened the manufacturing cycle also without processing on oil duct.
In the above-described embodiment, the oil duct 2 of engine cylinder-body can realize each several part lubrication of cylinder body 1 by multiple connected mode, as preferred embodiment, described oil duct 2 includes that main oil gallery 7, oblique oil duct 5, cylinder cap found oil duct 6 and back oil road 8, main oil gallery 7 is connected with lubricating oil pump 3, one end that oblique oil duct 5 founds oil duct 6 with cylinder cap is connected with main oil gallery 7, tiltedly the other end of oil duct 5 is connected with crankshaft link rod motion pair 10, the oil duct of the other end and cylinder cap 11 that cylinder cap founds oil duct 6 communicates, and back oil road 8 connects cylinder cap 9 and communicates with oil sump 4.Oil duct 6 and back oil road 8 is found so that lubricant passage way forms complete circulation canal, it is ensured that all parts of automobile engine can be lubricated after entering oil duct 2 by machine oil, it is ensured that working well of electromotor by the main oil gallery 7 arranged, oblique oil duct 5, cylinder cap.In this embodiment, the machine oil that its closed circuit is achieved in that in oil sump 4 enters into main oil gallery 7 after lubricating oil pump 3 is pressurizeed, a portion machine oil lubricates crankshaft link rod motion pair 10 by oblique oil duct 5, is returned directly in oil sump 4 after machine oil 10 lubrications secondary to crankshaft link rod motion；Another part machine oil founds, by cylinder cap, the oil duct that oil duct 6 enters on cylinder cap 11 and is lubricated the kinematic pair on cylinder cap 11, and flows back to oil sump 4 from back oil road 8.Wherein the oil duct on cylinder cap 11 and the oil duct in crankshaft link rod motion pair 10 are formed casting when.
In order to avoid the impurity in machine oil causes the abrasion of each moving component when lubrication, the path that main oil gallery 7 communicates with lubricating oil pump 3 is provided with oil filter 12.Thus so that machine oil is before entering main oil gallery 7, by oil filter 12, the contaminant filter in machine oil is fallen, it is ensured that the machine oil good lubrication to each moving component.Certainly, oil filter 12 can also be to be set directly on main oil gallery 7, as shown in Figure 3 so that a part of machine oil passes through oil filter 12 filtering, and another part directly arrives each moving component and is lubricated.
In order to the machine oil after all parts lubrication to cylinder cap 11 is fully recycled, as preferred embodiment, described back oil road 8 includes a plurality of point of oil return pipe 13 and a main oil return pipe 9, one end of a plurality of point of oil return pipe 13 communicates with the oil duct of cylinder cap 11, the other end communicates with main oil return pipe 9, and main oil return pipe 9 communicates with oil sump 4.The machine oil after the lubrication of all parts to cylinder cap 11 is made to flow back to oil sump 4 again after being flowed to main oil return pipe 9 by three points of oil return pipes 13, as another preferred embodiment, described back oil road 8 includes a plurality of point of oil return pipe 13, one end of a plurality of point of oil return pipe 13 communicates with the oil duct of cylinder cap 11, and the other end communicates with oil sump 4.Machine oil after all parts to cylinder cap 11 lubrication is directly flowed back in oil sump 4 by three points of oil return pipes 13.Certainly, in both embodiments, the concrete facilities of point oil return pipe 13 should be suitable with the drainback passage on cylinder cap 11.
In order to preferably improve the lubricating quality of machine oil, the path that lubricating oil pump 3 is connected with oil sump 4 is provided with sump strainer 14.Make machine oil when oil sump 4 is drawn into lubricating oil pump 3, primary filter can be carried out by sump strainer 14, can further improve engine oil quality.
In the above embodiment, oil pipe can use the oil pipe of different cross section form, but for the ease of the assembling with all parts, as preferred mode, described oil pipe is round tube.And in order to ensure that oil pipe and cylinder body 1 are firmly combined with, the outer surface of tube body of described oil pipe is uneven shape, as the outer surface of tube body of oil pipe being set to corrugated or arrange some ridges etc. protruding from outer surface of tube body；And in order to reduce machine oil flow resistance in oil pipe, the inner surface of tube body of described oil pipe is smooth surface.
