DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an engine oil filter mounting structure.

[0002]

2. Description of the Related Art In a conventional oil filter mounting structure, as shown in FIG. 8, an oil cooler 2 and an oil filter 3 are connected in series so as to project in a direction substantially perpendicular to a side surface of a cylinder block 1 of an engine. It was provided in the state where it was. Japanese Patent Application Laid-Open No. 63-160357 and Japanese Utility Model Application Laid-Open No. 64-7207 disclose such a mounting method. As another mounting method, as shown in FIG. 10, a mounting member 4 is provided on a side surface of the cylinder block 1, and an oil cooler 2 and an oil filter 3 are connected to the mounting member 4 in series. A method corresponding to this mounting method is also disclosed, for example, in Japanese Patent Application Laid-Open No. 3-54311.

[0003]

It is common to mount the same engine on different types of vehicles such as passenger cars and commercial vehicles. Since the size and shape of the engine room or the minimum ground height differs depending on the type of vehicle, the mounting posture of the engine is determined so as to fit each engine room. For example, as shown in FIG. 11, in a passenger car, the engine 6 is mounted vertically, and in a commercial vehicle, as shown in FIG. 12, the engine 6 is mounted in an inclined position.
When mounting this engine 6, the minimum ground clearance
Must be mounted above GL.

Therefore, there is no problem when the engine 6 is set in a vertical position as shown in FIG. 11, but the oil cooler and the oil filter are arranged so that the oil filter projects substantially perpendicularly to the side surface of the cylinder block. When the engine of the type in which the oil filters 3 are connected in series is mounted in an inclined position as shown in FIG. 9, the corners (a) of the oil filter 3 may be caught on the line GL of the minimum ground height, which is problematic. . In the engine room, the mounting density is high, various devices are densely arranged, and the engine 6 has a large external shape and occupies most of the space in the engine room. When the part (a) is raised to be higher than the minimum ground height line GL, the effect on the disposition of other equipment increases, and it is difficult to raise the engine itself. .

In order to make the corner (a) of the oil filter 3 higher than the minimum ground level line GL without raising the engine itself, as shown in FIG. 4 so that the oil filter 3 must be substantially parallel to the minimum ground height line GL, so that the number of assembled parts increases,
There is a problem that the strength of the mounting member 4 must be checked.

[0006] The present invention provides an engine oil filter mounting structure in which the oil filter does not fall below the minimum ground height line GL for any mounting position of the engine without providing a special mounting member. Things.

The oil passage and the oil suction oil passage communicating with the oil filter
It becomes easy to pass through.

[0012]

An embodiment of the present invention will be described below. FIG. 1 shows an oil filter mounting portion 8 of a bearing cap 7.
In addition, a lower oil filter mounting seat 9 and an upper oil filter mounting seat 10 are formed, and the lubricating oil communicating with the journal bearing portion 11 is shared by the lower oil filter mounting seat 9 and the upper oil filter mounting seat 10. Main oil passage 12
, An oil suction oil passage 13 is provided. That is, the lubricating oil pumped from an oil pump (not shown) passes through the oil cooler 2, the oil suction oil passage 13, the oil filter 3, and the lubricating oil main oil passage 12 (hereinafter, referred to as the lubricating oil passage), and is journaled. 11 to be supplied.

The lubricating oil main oil passage 12 and the oil suction oil passage 13 are opened to the lower oil filter mounting seat 9 and the upper oil filter mounting seat 10, for example, as shown in FIG. When the oil filter 3 is attached to the oil filter attachment seat 10, the opening of the lower oil filter attachment seat 9 is closed to form a lubrication path, or the lubrication oil main oil passage 12 and The oil suction oil passage 13 is not opened to the lower oil filter mounting seat 9 and the upper oil filter mounting seat 10, and when the oil filter 3 is mounted, the mounting seat is machined and opened. The lubrication path may be formed by leaving the mounting seat on the side where 3 is not mounted. FIG. 5 shows the bearing cap 7
FIG. 3 is a plan view showing an example in which communication holes 14 and 15 are opened in the surface of the upper oil filter mounting seat 10.

The operation of the embodiment constructed as described above will now be described. The oil filter mounting portion 8 of the bearing cap 7, so to form a lower oil filter attaching seat 9 and the upper oil filter attaching seat 10, in correspondence with the mounting position of the engine, the upper oil filter mounting, as shown in FIG. 1 The oil cooler 2 and the oil filter 3
Can be directly connected, and as shown in FIG. 2, the oil filter 3 can be mounted on the upper oil filter mounting seat 10, and the oil cooler 2 can be mounted on the lower oil filter mounting seat 9. It is possible.

As shown in FIG. 3, the oil cooler 2 and the oil filter 3 can be connected in series and mounted on the lower oil filter mounting seat 9, and as shown in FIG. It is also possible to mount the oil filter 3 on the mounting seat 9 and mount the oil cooler 2 on the upper oil filter mounting seat 10. Select Thus, to attach the oil cooler 2 and the oil filter 3 in series, or to separate the two, the lower oil filter attaching seat 9 or the upper oil filter attaching seat 10, respectively, in accordance with the mounting position of the engine It is possible to install it.

For example, as shown in FIG. 6, when the engine 6 is mounted vertically, the lower oil filter mounting seat 9
By mounting the oil filter 3 on the oil filter 2 and the oil cooler 2 on the upper oil filter mounting seat 10, there is no problem because the oil cooler 3 is sufficiently above the minimum ground height line GL. Seat 10
By installing a relatively small oil cooler 2, the oil filter 3 occupying the space in the engine room
It is also possible to reduce the occupancy of the oil cooler 2.

When the engine 6 is mounted at an angle as shown in FIG. 7, the oil cooler 2 and the oil filter 3 are connected in series, and the oil cooler 2 and the oil filter 3 can be higher than the minimum ground height line GL. 6 and 7, since the upper oil filter mounting seat 10 is inclined outward, the oil cooler 2 and the oil filter 3 can be mounted so as not to interfere with the cylinder block 1. . The above description has been made with reference to the bearing cap as an example.
If the lower oil filter mounting seat 9 and the upper oil filter mounting seat 10 are provided in the mounting portion 8, the operation is the same.

Further, a journal bearing portion 11 is attached to the lower oil filter mounting seat 9 and the upper oil filter mounting seat 10 provided on the upper and lower surfaces of the oil filter mounting portion 8, respectively.
The oil main oil passage 12 communicating with the oil filter 3 and the oil suction oil passage 13 to the oil filter 3 are shared, so that the main oil passage
A hole communicating with the oil suction passage 12 and the oil suction passage 13 is opened in the lower oil filter mounting seat 9 and the upper oil filter mounting seat 10, for example, as shown in FIG. When the filter 3 is mounted, the opening of the lower oil filter mounting seat 9 is closed to form a lubrication path, or a hole communicating with the lubricating oil main oil passage 12 and the oil suction oil passage 13. Are not opened in the lower oil filter mounting seat 9 and the upper oil filter mounting seat 10, and when the oil filter 3 is mounted, the mounting seat is machined to be opened so that the oil filter 3 is not mounted. The lubrication path is formed on the upper and lower surfaces of the oil filter mounting portion 8 by simplifying the structure, for example, by forming the lubrication path while leaving the mounting seat of the oil filter as it is. It is possible to form the lower oil filter attaching seat 9 and the upper oil filter attaching seat 10.
