Summary of the invention
The invention provides a kind of internal-combustion engine that comprises crankcase and upper oil pan at least.Crankcase comprises a plurality of main bearing cap of extending between pair of sidewalls, first group of hole arranged in main bearing cap and second group of hole arranged in sidewall.Upper oil pan is configured to and the respective surfaces of crankcase sealing engagement mutually, and comprises third and fourth group of hole by wherein.When upper oil pan engaged with crankcase, first group of Kong Yudi aimed in three groups of holes, and second group of hole and the 4th group of hole are aimed at.First group of fastening piece is extensiblely by first and the 3rd group of hole, and second group of fastening piece is extensiblely by second and the 4th group of hole simultaneously.When engaging, first and second groups of fastening pieces are combined into whole vibration and noise transmission with the minimizing motor with upper oil pan and crankcase side wall and main bearing cap.
Internal-combustion engine can also comprise the lower oil pan that defines oil sump, and upper oil pan is connected with lower oil pan.Upper oil pan can comprise oil purifier manifold and/or oil scraper, and preferably is configured to further provide oil baffle disc.Upper oil pan may further include a plurality of oil ducts so that the normal operation of internal-combustion engine.
In conjunction with the accompanying drawings, to realizing that best mode of the present invention is elaborated, above feature and advantage of the present invention and other feature and advantage will become apparent by following.
Description of drawings
Fig. 1 has shown according to internal-combustion engine of the present invention;
Fig. 2 has shown the perspective view of removing the motor of the Fig. 1 after the upper oil pan from crankcase; And
Fig. 3 has shown the downside of removing the motor of the Fig. 1 after the upper oil pan from crankcase.
Embodiment
With reference to accompanying drawing, wherein identical reference number refers to identical parts, and Fig. 1 shown and be typically expressed as 10 internal-combustion engine, and it comprises the upper oil pan 12 that is connected in crankcase 14, and lower oil pan 16 is connected in the bottom of upper oil pan 12.Lower oil pan 16 defines the oil conservator that is collected in the oil that is used for lubricated internal combustion engine component in the running.Preferably, food tray 12,16 constitutes by casting material, for example aluminum alloy, or other suitable lightweight materials.
Fig. 2 and 3 has shown the motor 10 after upper oil pan 12 removed from crankcase 14.Fig. 2 has shown the top of upper oil pan 12 with more details ground, and simultaneously, Fig. 3 has shown motor 10 from the motor downside in the mode of the bottom of detailed demonstration upper oil pan 12, to show notion of the present invention better.
Crankcase 14 comprises a plurality of main bearing cap 26 that are arranged between the sidewall 28.Sealing flange 30 can be arranged between crankcase 14 and the upper oil pan 12 to guarantee liquid-tight seal therebetween.A plurality of return openings 31 extend through sidewall 28 and flow out from cylinder head to allow oil, and this is known in this field.Crankcase 14 further comprises the speed changer mounting flange 32 that is used to be connected on the transmission for vehicles.
As shown in Figure 3, main bearing cap 26 comprises first group of preferably threaded hole 34, and crankcase side wall 28 comprises second group of preferably threaded hole 36 simultaneously.In addition, upper oil pan 12 comprises third and fourth group of hole 38,40.As shown in FIG., hole 34,36,38,40 is set so that first and second groups of holes 34,36 produce and is essentially leg-of-mutton layout, simultaneously, third and fourth group of hole 38,40 produces similarly and is essentially leg-of-mutton layout.Yet, can use any structure within the scope of the invention.Upper oil pan 12 matches with crankcase 14 so that hole 34 is aimed at hole 38, and simultaneously, hole 36 is aimed at hole 40.
First group of preferably threaded fastening piece 42 extends through the first group of hole 34 in the main bearing cap 26 and passes the 3rd group of hole 38 of upper oil pan 12.Similarly, second group of preferably threaded fastening piece 44 extends through the second group of hole 36 in the sidewall 28 of crankcase 14 and passes the 4th group of hole 40 of upper oil pan 12.Therefore first and second groups of fastening pieces 42,44 are bonded into overall structure with crankcase 14, upper oil pan 12 and main bearing cap 26.Just, upper oil pan 12 is effective as the structural element of crankcase 14, and main bearing cap 26 is interconnected, and also is connected to crankcase side wall 28 simultaneously.Overall structure has reduced the distortion that is applied to main bearing cap 26 by bent axle 14, thereby under the situation that does not increase engine weight, the vibration and the noise that have limited motor 10 generations disseminate.Especially, by upper oil pan 12 being connected to crankcase side wall 28 and main bearing cap 26, bearing load is dispersed in sidewall 28 and main bearing cap 26.
What deserves to be mentioned is that in the preferred embodiments of the present invention as shown in the figure, second group of fastening piece 44 extends through the bottom of sidewall 28, rather than pass through the sidepiece of sidewall 28.Arrange that in this mode second group of hole 36 be convenient to various other vehicle components are connected to crankcase 14.For example, typically, be installed in the parts on the motor, for example air condition compressor or power-assisted steering pump can be at the sides that does not need to avoid to be installed under the situation of second group of fastening piece 44 sidewall 28.Therefore, by arranging second group of fastening piece 44 bottom by sidewall 28, the present invention will provide better intensity and rigidity in the minimization of loss of the connection space of crankcase 14.
Refer back to Fig. 2, upper oil pan 12 preferably is configured to comprise a plurality of oil ducts.Especially, the oil pump (not shown) is pumped into oil in the upper oil pan 12 by filler opening 46.About 10% oil that enters by filler opening 46 flows out by filter cleaner outlet 48, and enters into the oil filter (not shown).Other 90% oil that enter by filler opening 46 flow out to the oil cooler (not shown) by cooler outlet 50, and reenter upper oil pan 12 by cooler inlet 52.Extra oil also by behind the oil purifier (not shown), enters motor 10 by oil purifier manifold 22, and enters into crankcase 14 by engine export 54.Therefore as can be seen, a plurality of oil ducts are provided upper oil pan 12 according to the present invention so that the normal operation of motor 10.
Be used to realize best mode of the present invention though described in detail, should be appreciated that employed term only has the character of word and description, rather than limit.This technician who invents related field should be realized that according to above instruction many improvement of the present invention are possible.Therefore, can know, within the scope of the appended claims, except as in the mode of this specific description, the present invention can also realize in the mode that is equal to basically.
