Description
- The present invention relates to the structure of an oil pan for an internal combustion engine.
- In a case of the prior art, as shown in FIG.14 or FIG.15, an
oil pan 3 is mounted directly or through anadapter plate 2 on acylinder block 1 of an internal combustion engine. Theoil pan 3 comprises a boxlikeupper part 3d made of aluminum alloy and a lidlike lower part 3g made of steel plate or aluminum alloy. Thisoil pan 3 has a structure as shown in a front view of FIG.16, plan view of FIG.17, bottom view of FIG.18, and partly sectional side view of FIG.19. - Namely, formed on the top of the
upper part 3d constituting theoil pan 3 is amounting surface 3e for mounting itself on thecylinder block 1 and formed on the bottom of theupper part 3d is alower mounting surface 3f on which the lower part 3g is mounted. Formed at the left end of theupper part 3d is anopen end 3a that is open and vertical to thecentral axis 4a of thecrankshaft 4 and formed oppositely at the right end is a closedend 3b that is closed. - Integrally formed on the boxlike
upper part 3d is abaffle plate 3c to restrict thrashing of lubrication oil surface that occurs during the operation of the internal combustion engine. - An
oil pump 5 for supplying lubrication oil to the engine is a separate component, which is secured to the under surface of thecylinder block 1 oradapter plate 2 with a plurality ofbolts 6. Theoil pump shaft 5a is provided with asprocket 5b to which the rotating force is transmitted through a chain, belt, gear, etc from thecrankshaft 4 to operate theoil pump 5. Incidentally, anoil strainer 7 for sucking lubrication oil inside theoil pan 3 is mounted on the under surface of theoil pump 5 withbolts 6 or formed integrally with theoil pump 5. - In such a structure, there are problems such as a large quantity of parts, increase of cost and weight in the whole engine. Besides, since the
oil pump 5 is a separate component, it is impossible to arrange reinforcement ribs favorably to secure the rigidity of theoil pan 3 on the periphery of theoil pump 5 in theupper part 3d. As a result, there is a problem that the rigidity of thewhole oil pan 3 is insufficient, vibration of the whole engine is not controlled, and the noise is increased during the operation of the vehicle. - In order to solve the foregoing problems, such a structure may be thought that the
oil pump 5 is disposed, as shown in FIG.20, coaxially on thecentral axis 4a of thecrankshaft 4 and integrated with acover 9 covering the open end on the side where theoil pump 5 is disposed so as to decrease the number of parts. In such a structure, theoil pump 5 must be inserted into thecrankshaft 4, so that it is required to extend the axial length of thecrankshaft 4. As a result, such a structure has a weak point that the axial length of the crankshaft becomes longer, so that it is apt to be restricted to install the engine on a vehicle. - The present invention is worked out in view of the above-described problems in the prior art. It is an object of the present invention to provide an oil pan for an internal combustion engine that can decrease the number of parts and weight, enhance the rigidity and minimize the axial length of the crankshaft.
- The first subject matter of the present invention is an oil pan for an internal combustion engine comprising an upper part mounted directly or through an adapter plate on the bottom of an cylinder block, a lower part covering the bottom of the upper part, the upper part provided with an open end at one end thereof vertically crossed to the central axis of the crankshaft, and the upper part provided integrally with a baffle plate made of aluminum alloy to restrict thrashing of lubrication oil, wherein a vertical wall is provided integrally near the open end of the upper part vertically crossed to the central axis of the crankshaft, and the vertical wall is provided with an oil pump to supply lubrication oil to the internal combustion engine.
- The second subject matter is that in the foregoing oil pan, a lower oil passage is formed integrally on the vertical wall or the wall of the baffle plate to introduce the lubrication oil in the oil pan through an oil strainer into the oil pump.
- The third subject matter is that in the foregoing oil pan, an upper oil passage is formed parallel to the central axis of the crankshaft and integrally on the baffle plate or the side wall of the upper part or the connecting part between the baffle plate and the side wall to introduce the lubrication oil in the oil pan through the discharge side into an oil filter.
- The fourth subject matter is that in the foregoing oil pan, a boss portion for mounting an oil filter is formed integrally on the sidewall of the upper part on which the upper oil passage is formed as a unit.
- Therefore, an advantage of the oil pan according to the invention is that it is possible to decrease the number of parts, weight and cost and to minimize the axial length of the crankshaft and further to enhance the degree of freedom for installation of the internal combustion engine on a vehicle and also the rigidity of the oil pan owing to the vertical wall.
- Another advantage of this oil pan according to the second subject matter is that it is possible to minimize the addition of the weight and to enhance the rigidity of the oil pan owing to the lower oil passage.
- A further advantage of this oil pan according to the third subject matter is that it is possible to minimize the addition of the weight and to enhance the rigidity of the oil pan.
- A still further advantage of this oil pan according to the fourth subject matter is that it is possible to mount an oil filter on the boss portion from the outside and to make it easy to exchange the oil filter.

oil pan 3 that is mounted directly or through anadapter plate 2 on acylinder block 1 as shown in FIG.14 or FIG.15 described above, FIG.2 is a plan view thereof, FIG.3 is a bottom view thereof, and FIG.4 is a partly sectional side view thereof. - Incidentally, the same component as in the structure described above will be described by assigning the same reference number thereof.
- The
oil pan 3 comprises anupper part 3d and a lower part 3g. In both ends of theupper part 3d vertically crossed to thecentral axis 4a of the crankshaft, the left side is open and forms anopen end 3a and the right side closed and a closedend 3d, as best shown in FIG.2. - The
upper part 3d is provided integrally with abaffle plate 3c made of aluminum alloy between the side walls 3p parallel to thecentral axis 4a of the crankshaft, as shown in the A-A line sectional view of FIG.5. Thebaffle plate 3c is partly provided with awall surface 3m formed downward in a hollow fashion. - The top periphery of the
upper part 3d forms amounting surface 3e to be mounted on thecylinder block 1 oradapter plate 2 and the under periphery of the same forms alower mounting surface 3f to mount the lower part 3g thereon. - Integrally formed near the
open end 3a of the boxlikeupper part 3d is avertical wall 3h crossed at right angles to thecentral axis 4a of the crankshaft. Thisvertical wall 3h is fitted with anoil pump 5. - Now, referring to FIG.6, FIG.7, and FIG.8, the
vertical wall 3h is formed in a hollow fashion and theoil pump 5 is fitted thereto with bolts from theopen end 3a. Agear 5c of theoil pump 5 is disposed inside thevertical wall 3h. The inside of thevertical wall 3h forms an oil chamber, from which ashaft 5a of theoil pump 5 is projected toward theopen end 3a. Provided on the tip of theshaft 5a is asprocket 5b, which is engaged with a chain, belt, gear, or the like so as to receive the rotating force from thecrankshaft 4. - As shown in FIG.3, FIG.8, and FIG.9, the bottom of the
baffle plate 3c is provided with anoil strainer 7 with asuction inlet 7a projecting downward into the lower part 3g. Thisoil strainer 7 is disposed in a position to immerse itself in the lubrication oil collected in theoil pan 3. - As shown in FIG.5, FIG.8, and FIG.9, integrally formed on the bottom of the
wall 3m forming thebaffle plate 3c is alower oil passage 3j to be nearly parallel to thecentral axis 4a of the crankshaft. Thelower oil passage 3j makes thesuction inlet 7a of theoil strainer 7 communicate through aninlet 7b with the oil chamber inside the vertical wall h involving thegear 5c of theoil pump 5. - Accordingly, this
lower oil passage 3j is capable of introducing the lubrication oil sucked from theoil strainer 7 through theinlet 7b to thegear 5c of theoil pump 5. - As shown in FIG.5, FIG.6, and FIG.7, integrally formed on the
baffle plate 3c parallel to thecentral axis 4a of the crankshaft, or on one of the side walls 3p parallel to thecentral axis 4a, or on the area joining thebaffle plate 3c to the side wall 3p is anupper oil passage 3n to introduce the lubrication oil from the sectional area-changing portion 7c at the discharge side of theoil pump 5 to theoil filter 8. - Accordingly, the lubrication oil discharged by rotation of the
gear 5c of theoil pump 5 runs along thisupper oil passage 3n and is supplied through theoil filter 8 into the internal combustion engine. - Incidentally, it is possible that the lower and the
upper oil passage upper part 3d of theoil pan 3 by pressure die-casting, which is relatively inexpensive as the process of aluminum alloy casting. - Also, the foregoing
vertical wall 3h may be formed integrally with theupper part 3d. Thevertical wall 3h,lower oil passage 3j andupper oil passage 3n are capable of functioning as rigidity members in addition to the oil passages, so that the whole of theoil pan 3 is enhanced in its rigidity. - Besides, another embodiment of the invention is illustrated in FIG.10 and FIG.11. Integrally formed on the sidewall 3p of the
upper part 3d is a boss portion 3q communicating with the foregoingupper oil passage 3n so that theoil filter 8 may be mounted on this boss portion 3q from the outside. In case the boss portion 3q is integrally formed, it becomes easy to exchange theoil filter 8, so that the dust in the lubrication oil is favorably caught through thisoil filter 8 and the lubrication oil without dust may be satisfactorily supplied into the internal combustion engine. - Having described the invention in detail and by reference to the preferred embodiment thereof, it will be apparent that other modifications and variations are possible without departing from the scope of the invention defined in the appended claims.
