Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a support device used when an engine is mounted on a car or installed on a floor.

(Prior Art) In general, when an engine is mounted on an automobile, the support structure is such that a boss is integrally attached to the cylinder block (in the above publication, the mounting seat is ), and is supported by the vehicle body etc. via an engine mount bracket attached to the boss and a vibration isolator.

However, in the case of automobile engines,
The mounting position is different for a front-engine, front-drive vehicle and a front-engine, rear-drive vehicle, and is also different when mounted on a forklift or installed on the floor for power generation. In that case, if the cylinder block is supported using an integral boss as described above, the cylinder block itself must be changed for each engine with a different mounting position, even if the engine is the same model. Furthermore, as the mounting position changes, the various auxiliary equipment mounted around the cylinder block must be rearranged each time. Therefore, the manufacturing cost of the engine becomes significantly high.

(Purpose of the invention) This invention deals with the above-mentioned problems regarding engines installed under various support conditions such as for automobiles, forklifts, power generation, etc. It is an object of the present invention to provide a support device that can accommodate various different support conditions without requiring changes in the layout of auxiliary equipment, thereby reducing the manufacturing cost of this type of engine.

(Structure of the invention) That is, the engine support device according to the invention is an engine in which an oil pan is attached to the lower surface of a cylinder block using a fastening bolt, and the engine support device is annular and corresponds to the flange surface of the oil pan. Equipped with an engine mount bracket with bolt holes formed in positions corresponding to the bolt holes on the surface,
The bracket is disposed below the flange surface and is fastened together with the oil pan to the cylinder block by the fastening bolt, and the engine mount bracket is provided with a projecting piece that projects outward and is fixed to the mount member. It is characterized by With such a configuration, it is possible to respond to various support conditions with different mounting positions by simply changing the engine mount bracket. In this case, according to the above structure, the overall height of the engine does not increase due to the engine mount bracket, and the sealing performance at the joint between the cylinder block and the oil pan does not deteriorate.

(Example) The present invention will be described below based on an example shown in the drawings.

Figure 1 shows a case in which a power generation unit consisting of an engine 1 and a generator 2 is installed on a frame 3 laid on the floor. At the same time, a projecting piece 6a provided on the engine mount bracket 6 projects laterally from the vicinity of the joint between the lower surface of the cylinder block 4 and the upper surface of the oil pan 5.

On the other hand, a plurality of first mount members 7 having anti-vibration rubber are fixed on the frame 3, and a second mount member 8 is attached to each of the first mount members 7, respectively. The projecting piece 6a of the engine mount bracket 6 is fixed onto the second mount member 8 located at the front, and the side surface of the generator 2 is coupled to the second mount member 8 located at the rear. The power generation unit is supported by the power generation unit.

However, the engine mount bracket 6
As shown in FIGS. 2 and 3, is formed into a substantially rectangular ring shape corresponding to the shape of the flange surface 5a provided around the upper surface of the oil pan 5, and protrudes outward from both sides. It has a shape in which protruding pieces 6a, 6a are provided. Further, a large number of bolt holes 6b...6b are formed in positions corresponding to the large number of bolt holes 5b...5b formed in the flange surface 5a of the oil pan 5, and bolt holes are also formed in the protruding pieces 6a, 6a, respectively. 6c...6c are formed.

And this engine mount bracket 6
are fastened together below the flange surface 5a of the oil pan 5 when the oil pan 5 is attached to the lower surface of the cylinder block 4. That is, the fastening bolts 9...9 for fastening the oil pan 5 to the cylinder block 4 are first inserted into the bolt holes 6b...6b in the engine mount bracket 6 from below, and then inserted into the bolt holes 5b...5b in the oil pan flange surface 5a. The bolt holes 10a...10a of the gasket 10 are inserted into the joint between the oil pan 5 and the cylinder block 4, and then the bearing surface 4a of the cylinder block 4 is inserted.
They are screwed into screw holes 4b...4b formed in the respective parts. As a result, the engine mount bracket 6 is connected to the cylinder block 4 while being disposed below the flange surface 5a of the oil pan 5. In this case, as shown in FIG. 3, since a downwardly folded portion 5c is provided on the peripheral edge of the flange surface of the oil pan 5, the folded portion 5c and the projecting piece 6a of the engine mount bracket 6 The protruding piece 6a is attached to the bracket 6 so that it does not interfere with the bracket 6.
It is made one step lower than the upper surface 6d and protrudes laterally.

The engine mount bracket 6 thus assembled and integrated with the engine 1 is placed on the second mount member 8 at the left and right projections 6a, and inserted into the bolt holes 6c, as shown in FIG. The engine 1 is coupled to the mount member 8 using bolts 11 and nuts 12.
is supported. Here, the projecting piece 6a of the engine mount bracket 6 is made sufficiently thick so as to support the weight of the engine 2.

In particular, according to the above configuration, the flange surface 5a of the oil pan 5 is fastened to the seat surface 4a of the cylinder block 4 via only the gasket 10, as in the conventional case, so that the cylinder block 4 and the oil pan 5 are connected to each other. The sealing performance of the fastening portion of the oil pan 5 does not deteriorate, and the overall height of the engine does not increase due to the attachment of the engine mount bracket 6. In addition, when the flange surface 5a of the oil pan 5 is not sufficiently rigid, the engine The mount bracket 6 reinforces the flange surface 5a and brings the flange surface 5a and the cylinder block seating surface 4a into even pressure contact via the gasket 10, which has the advantage of improving sealing performance.

(Effects of the invention) As described above, according to the support device of the present invention, the engine is supported by the engine mount bracket which is fastened to the cylinder block together with the oil pan. Even when installed under support conditions, it is possible to adapt to each support condition by simply replacing the engine mount bracket. As a result, when engines of the same model are used for automobiles, forklifts, power generation, etc., and in the case of automobiles, these engines can be used for front engine front drive cars or front engine rear drive cars. It becomes possible to share the cylinder block in the cylinder block, and there is no need to change the layout of auxiliary equipment around the cylinder block. Consequently, the manufacturing cost of this type of engine is reduced. Particularly, according to the present invention, the provision of the engine mount bracket does not cause problems such as an increase in the overall height of the engine and a decrease in sealing performance at the joint between the cylinder block and the oil pan.
