DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an oil level gauge mounting structure for an automobile, and in particular, an oil level gauge for an automobile capable of facilitating the layout of the oil level gauge and compactifying the entire internal combustion engine. Regarding mounting structure.

[Conventional technology]

In an internal combustion engine of an automobile, an oil pan is provided on the lower bottom surface of a cylinder block, and lubricating oil (oil) for the internal combustion engine is stored in this oil pan. An oil level gauge is provided to be inserted into and removed from the oil pan in order to measure the amount of lubricating oil in the oil pan.

As the mounting structure of the oil level gauge, for example, as shown in FIGS. 7 (a) and 7 (b), the cylinder block 102
An oil pump 104 is attached to a lower side surface 102a of the cylinder block 102, and an upper end portion 112 connected to a side wall 110 of an oil pan 108 is brought into contact with a lower bottom surface 102b of the cylinder block 102 and a bottom surface 106b of a flange portion 106 of the oil pump 104, and the flange Oil level gauge insertion hole 116 for inserting the oil level gauge 114 into the portion 106
The oil level gauge 114 is formed by inserting the oil level gauge 114 from above into the oil level gauge insertion hole 116.
There is something to insert inside.

Further, as the oil level gauge mounting structure, as shown in FIG. 8, the outer wall of the cylinder block 204 of the internal combustion engine 102 is
There is one in which an oil level gauge insertion hole 208 is formed in 206 and the oil level gauge 212 is inserted into the oil pan 210 from the side of the cylinder block 204. In FIG. 8, reference numeral 214 is a cylinder head and 216 is an oil strainer.

Further, as the oil level gauge mounting structure, as shown in FIG. 9, an oil level gauge insertion hole 306 is formed in the side wall 304 of the oil pan 302, and the oil level gauge 308 is directly attached from the side of the side wall 304 of the oil pan 302. Some are inserted into the oil pan 302. In FIG. 9, reference numeral 310 is a cylinder block, and 312 is an oil pump.

Further, as an oil level gauge mounting structure, for example, there is one described in Japanese Utility Model Laid-Open No. 62-82312. In the one disclosed in this publication, an oil level gauge insertion hole is formed in a side wall of an oil pan, and a joint portion of the oil level gauge is fixed to the oil level gauge insertion hole.

[Problems to be solved by the invention]

However, in the conventional oil level gauge mounting structure, as shown in FIGS. 7 (a) and 7 (b), when the oil level gauge is inserted from the oil pump, the oil level gauge is placed against the oil surface of the lubricating oil. If it is attempted to insert it vertically, it is necessary to orient the oil level gauge vertically, and therefore it is necessary to make the oil pump and the oil pan large in size, which causes a problem that the entire internal combustion engine becomes large in size.

Further, as shown in FIG. 8, when the oil level gauge is inserted from the side of the cylinder block, it is necessary to make the cylinder block large in order to avoid interference between the oil level gauge and other parts. Therefore, there is a disadvantage that the entire internal combustion engine becomes large.

Furthermore, as shown in FIG. 9, when the oil level gauge is inserted from the side of the oil pan, the angle at which the oil level gauge is inserted is limited, and the layout of the oil level gauge becomes difficult. .

[Purpose of device]

Therefore, in order to eliminate the above-mentioned inconvenience, the object of the present invention is to extend a part of the flange portion of the oil pump laterally to form the hole forming portion and to correspond to the hole forming portion, the side wall of the oil pan. And an oil level gauge insertion hole, one end of which opens on the outer surface of the hole forming portion and the other end of which opens inside the oil pan on the inner surface of the hole forming portion. In this way, the layout of the oil level gauge can be facilitated and an oil level gauge mounting structure for an automobile that can make the entire internal combustion engine compact can be realized.

[Means for solving problems]

In order to achieve this object, the present invention has an oil pump attached to the lower side surface of a cylinder block of an internal combustion engine of an automobile, and an oil pan is provided on a bottom bottom surface of the cylinder block and a bottom surface of a flange portion of the oil pump. A part of the flange portion of the pump is laterally extended to form a hole forming portion, and the side wall of the oil pan is laterally extended to correspond to the hole forming portion. Has an oil level gauge insertion hole, one end of which opens to the outer surface of the hole forming portion and the other end of which opens to the inside of the oil pan on the inner surface of the hole forming portion.

[Action]

According to the configuration of the present invention, when the oil level gauge is inserted through the oil level gauge insertion hole, the oil level gauge can be positioned in a substantially vertical direction with respect to the oil surface of the lubricating oil. The oil level gauge can be installed accurately, and the oil level gauge can be installed without increasing the size of the oil pump, the oil pan, or the cylinder block. Can be

Embodiments of the present invention will be described in detail and specifically below with reference to the drawings.

1 to 6 show an embodiment of the present invention.
In FIG. 1, 2 is an internal combustion engine, 4 is a cylinder block, 6 is a cylinder head, 8 is an oil pan, and 10 is a camshaft. The oil pan 8 is attached to the lower bottom surface 4a of the cylinder block 4 by attachment bolts 12.

Lubricating oil for the internal combustion engine 2 is stored in the bottom portion of the oil pan 8.

In the oil pan 8, the cylinder block 4
An oil strainer (16) held by a strainer rod (14) fixed to the lower bottom surface (4a) is arranged.

Further, an oil pump 20 is attached to the lower side surface 4b of the cylinder block 4 to suck the lubricating oil in the oil pan 8 through the oil strainer 16 and pressure-feed it to the main oil passage 18 side of the cylinder block 4.

A relief oil passage 22 is connected in the middle of the main oil passage 18, and a relief valve is provided in this relief oil passage 22.
24 are provided.

A baffle plate 26 is arranged in the oil pan 8 substantially parallel to the lower bottom surface 4a of the cylinder block 4.

The bottom surface 28a of the flange portion 28 of the oil pump 18 (second, third
(Refer to the drawing), the upper end portion connected to the side wall 30 of the oil pan 8
32 are provided in abutment with each other (see FIGS. 5 and 6).

In the flange portion 28 of the oil pump 18, a hole forming portion 34 is formed by laterally extending a part of the flange portion 28.

Corresponding to the projecting hole forming portion 34, as shown in FIGS. 5 and 6, a part of the side wall 30 of the oil pan 8 is located further than the conventional portion (shown by a broken line R in FIG. 5). The upper end portion of the flange portion 28 of the oil pump 20 is located at the tip end side of the oil pump 20.

2 to 4, one end of the hole forming portion 34 is open to the outer surface 34a of the hole forming portion 34 and the other end is the inner surface 34b of the hole forming portion 34, which is the oil pan 8. An oil level gauge insertion hole 36 that opens inside is formed.

As shown in FIGS. 1 and 4, an oil level gauge 38 for indicating the oil level of the lubricating oil, that is, for detecting the amount of the lubricating oil is inserted through the oil level gauge insertion hole 36.

The oil level gauge 38 is a gauge tube 40 held on the side surfaces of the oil pump 8 and the cylinder head 6.
Is inserted from above and the tip side is inserted into the oil pan 8 to indicate the amount of lubricating oil.

 Next, the operation of this embodiment will be described.

When the oil level gauge 38 is inserted into the gauge tube 40 from above, the tip side of the oil level gauge 38 is inserted into the oil pan 8 through the gauge tube 40 and the oil level gauge insertion hole 36.

At this time, attach the oil level gauge insertion hole 36 to the flange portion.
If formed in a direction substantially orthogonal to the bottom surface 28a of 28, the tip end side of the oil level gauge 38 is positioned substantially vertically to the oil surface of the lubricating oil in the oil pan 8.

Therefore, even when the oil level gauge 38 is inserted from the oil pump 20 into the oil pan 8 and the oil level gauge 38 is positioned substantially vertically to the oil surface of the lubricating oil, the large size of the oil pump 20 and the oil pan 8 are large. Can be avoided.

Further, since the oil level gauge 38 can be inserted into the oil pan 8 without increasing the size of the entire oil pan 8, it is possible to avoid increasing the size of the oil pan 8.

Furthermore, since the oil level gauge 38 is not inserted from the side of the cylinder block 4, there is no need to consider interference with other parts, and the cylinder block 4 can be prevented from becoming large.

Furthermore, since the oil level gauge 38 can be inserted into the oil pan 8 using the flange portion 28 of the oil pump 20, the layout of the oil level gauge 38 can be facilitated.

As a result, when the oil level gauge 38 is inserted into the oil pan 8, a part of the flange portion 28 of the oil pump 20 is extended and a part of the side wall 30 of the oil pan 8 is extended. Since the oil level gauge 38 can be mounted in the space, the layout of the oil level gauge 38 can be facilitated, the periphery of the oil level gauge 38 can be made compact, and the internal combustion engine 2 as a whole can be made compact. .

[Effect of device]

A part of the flange portion of the oil tank is extended laterally to form a hole forming portion, and the side wall of the oil pan is extended laterally so as to correspond to the hole forming portion. By forming an oil level gauge insertion hole that opens on the outer surface of the forming part and the other end opens inside the oil pan on the inner surface of the hole forming part, the mounting angle of the oil level gauge is not limited. The layout can be facilitated, and the internal combustion engine as a whole can be made compact by preventing the oil pump, the oil pan, and the cylinder block from increasing in size.
