Description

Automotive engine mountings

The present invention relates to an engine mounting of an automobile, and more particularly to an engine mounting apparatus of an automobile having a structure in which the mounting support shaft is pressed into the vehicle body bracket.

Typically, when the engine is mounted on the vehicle body, the engine is supported by the engine mounting fixed by means of fastening means such as bolts to a plurality of engine brackets and supports connected to the vehicle body in order to prevent vibration of the vehicle body from being transmitted to the engine. Is mounted. Such engine mounting prevents the vibration generated from the engine rotating at high speed to be transmitted to the driver through the vehicle body or to prevent the vibration of the vehicle body from being transmitted to the engine while driving the vehicle, thereby transmitting excessive force to the engine. It is to prevent.

For this purpose, the structure of the engine mounting is a dustproof structure that absorbs and suppresses vibration or other noise generated from the engine or the vehicle body. Such a dustproof structure usually uses an annular or cylindrical dustproof rubber surrounded by a metal bracket, and is installed in brackets connected to the vehicle body and the engine at upper and lower portions of the dustproof rubber by fasteners such as bolts at the center of the dustproof rubber.

On the other hand, another type of engine mounting for supporting the engine is of the type as shown in FIG. The engine mounting shown in FIG. 1 is installed in the vehicle body, and has a first plate on the outside with a large hole and a second plate on the inside with a small hole, and the brackets on which the first and second plates are formed in parallel; It has a first diameter portion penetrating the hole of the first plate of the bracket and a second diameter portion penetrating the hole of the second plate, the first diameter portion and the second diameter portion as shown in Figure 2 An engine mounting portion made of rubber supported by a support shaft welded and fixed to holes formed in the first and second plates, respectively, with the end face caught by the holes of the second plate, and a second diameter portion of the support shaft; And a nut screwed to an end of the second diameter portion of the support shaft to prevent the engine mounting portion from being detached from the support shaft.

Engine mounting having the structure as described above is supported by the engine in the engine mounting portion absorbs the vibration and shock transmitted from the engine to the vehicle body or from the engine as described above to protect the engine and the body and ride comfort for passengers Improve.

However, in the conventional engine mounting of the type described above, since the engine mounting portion is welded and fixed to the bracket, when the engine is loaded for a long time, the welded portion of the support shaft becomes unbalanced. Not only can it be separated from the bracket, but also the support shaft has to be welded to the bracket as a whole along the circumference of the support shaft, causing a problem of causing an increase in manufacturing cost.

Accordingly, it is an object of the present invention to provide an engine mounting apparatus for a vehicle having a structure that prevents the support shaft from being separated from the bracket even in a long period of use, and which can be fixed to the bracket in a simpler manner.

1 schematically illustrates a conventional engine mounting.

Figure 2 is a view showing a state in which the mounting support shaft of Figure 1 welded to the bracket.

3 is a view similar to that of FIG. 2 of an engine mounting apparatus for a motor vehicle according to the invention.

* Explanation of symbols for main parts of the drawings

1: 1st flat plate 2: big hole

3: support shaft 4: second flat plate

5: small hole

The above object is a bracket which is provided in the vehicle body, has a first outer plate having a large hole formed therein and a second inner plate having a small hole formed therein, and the first and second plates formed in parallel with each other. The first diameter portion penetrates the hole of the first plate and the second diameter portion penetrates the hole of the second plate, and the first diameter portion is pressed into and fixed to the hole formed in the first plate, and the end face of the first diameter portion is An engine mounting portion made of a support shaft caught by the hole of the second plate, a rubber supported by the second diameter portion of the support shaft, and an end portion of the second diameter portion of the support shaft to prevent the engine mounting portion from being separated from the support shaft. It is achieved by an engine mounting apparatus according to the invention, characterized in that it comprises a nut which is screwed together.

In the above, the first diameter portion of the support shaft has the shape of serration, and the first diameter portion formed on the first flat plate of the bracket may also have the shape of serration.

According to the engine mounting according to the present invention as described above, the support shaft is prevented from being separated from the bracket even when used for a long time by being press-fit fixed to the hole formed in the parallel plate of the bracket fixed to the vehicle body, It is installed on the bracket.

EXAMPLE

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a view similar to FIG. 2 of an engine mounting apparatus for a vehicle according to the present invention. As can be seen from Fig. 3, the engine mounting apparatus according to the present invention has a first diameter of the support shaft 3 in the large hole 2 formed in the first flat plate 1 provided on the outside of the bracket installed in the vehicle body. The part 3a is press-fitted and fixed. The inner side of the second flat plate 4 parallel to the first flat plate 1 has a smaller hole 5 formed therein, and the end face of the first diameter portion 3a is second when the support shaft 3 is press-fitted. The hole 5 of the flat plate 4 is caught.

In this state, the engine mounting portion (see FIG. 1) made of rubber is supported by the second diameter portion 3b of the support shaft 3 extending outward through the second flat plate 4, and the engine mounting A nut (see FIG. 1) is screwed into the end of the second diameter portion 3b of the support shaft 3 to prevent it from being disengaged from the additional support shaft 3.

On the other hand, the first diameter portion 3a of the support shaft 3 is formed in the shape of a serration so as to be easily press-fitted, and the first diameter portion 2 of the first flat plate 1 of the bracket also having the shape of serration. ) Is pressed in and fixed.

As described above, according to the engine mounting apparatus according to the present invention, the support shaft is press-fitted into a hole formed in the parallel plate of the bracket fixed to the vehicle body, thereby preventing separation from the bracket even when used for a long period of time, and more simply the support shaft This bracket is installed.
