DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bracket structure for an automobile engine mount, and more particularly, to a bracket structure for protecting the mount from heat, dirt, and stepping stones.

[0002]

2. Description of the Related Art A bush mount type 1 as shown in FIG. 6 is used as an engine mount.
And a liquid-filled type 2 shown in FIG. 7 are generally used. The bush mount type 1 elastically supports a metal inner cylinder 5 in a metal outer cylinder 3 via an elastic body 4. The liquid enclosing type 2 is one in which a liquid is sealed inside an outer shell 6 formed of an elastic body such as rubber.
Each of them has a great effect for reducing the muffled sound and the body vibration by interposing the vibration source at the joint position between the engine and the vehicle body structure.

The bush mount type 1 shown in FIG.
As disclosed in Japanese Utility Model Laid-Open Publication No. 3-69732,
Since the shaft is passed through the inner cylinder 5 and the shaft is supported from both sides of the mount 1 by the mount bracket 7, the side surface of the elastic body 4 is covered by the mount bracket 7. In addition, since the elastic body 4 is covered with the outer cylinder 3, it is possible to prevent collision of a stepping stone or the like at the time of direct traveling on the elastic body 4 and adhesion of sewage or the like. However, when a heat source such as an exhaust pipe is provided near the mount, the outer cylinder 3 receives radiant heat from the heat source, and the heat is transmitted to the elastic body 4.

The liquid-filled type 2 shown in FIG. 7 is generally used in such a manner that the mount 2 is usually superimposed on the body-side bracket 8, and the engine-side mount bracket 9 is further superimposed thereon.

[0005] As another prior art, Japanese Utility Model 2-8
No. 116 is disclosed. This technique is
As shown in FIG. 8, two bowl-shaped metal pieces 10 and 11 face each other and are combined in a box shape, and an elastic body 12 such as rubber is vulcanized inside the box shape, so that the metal piece and the elastic body are combined. It is formed integrally. FIG. 9 shows a case in which a separate protective member C is used to protect the mounting rubber, which is disclosed in detail in Japanese Utility Model Laid-Open No. 2-85055.

[0006]

The above-mentioned methods have the following problems. In the conventional method using a liquid-filled mount shown in FIG. 7, since the mount 2 is exposed, deterioration of the elastic material due to radiant heat from a heat source such as an exhaust pipe is directly applied to the outer shell 6 or running. It was not possible to prevent degradation due to collision of stepping stones or the like and adhesion of sewage or the like. In the method shown in FIG. 8, the integral molding involves some technical difficulty, and is expensive as a part. The method shown in FIG. 9 has caused an increase in the number of components due to the use of a separate protective member C for protecting the mounting rubber.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to form a mount from heat or stepping stones without increasing the number of parts by forming a wall portion on a mount bracket. The purpose is to protect and extend the useful life of the mount.

[0008]

Means for solving the above problems according to the present invention is to provide an engine mount that supports the mount from the body side when the engine is mounted on the body via a liquid-filled mount. The bracket is characterized in that at least one pair of opposed wall surfaces is formed so as to cover substantially the side surface of the mount by bending a side portion of the mount mounting base of the bracket.

[0009]

The function of the bracket is to add a function as a mount cover to the bracket by bending the side of the mount mounting base portion of the bracket to form a wall surface surrounding the mount.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the drawings.

A mounting bracket 13 for an engine (hereinafter simply referred to as a bracket) 13 shown in FIG. 16, 17, 18
Is provided. A hole 20 for screwing the bracket 13 to the vehicle body frame 19 is formed in the wall surface 18. The upper part of the mount 14 is connected to an engine-side mount bracket 22 via a stopper 21. Further, as shown in FIG. 2, the mount 14 and the bracket 13 are arranged in the vicinity of an exhaust device 24 coming out of the engine 23, and are installed in a place receiving radiant heat from the exhaust device 24.

As shown in FIGS. 3 and 4, the bracket 13 is formed by bending a single plate material, and the workability is very good. The mount 14 is covered by the combination with the stopper 21.

The radiant heat generated from the exhaust device 24 is blocked by the stopper 21 and the wall surfaces 16 and 17 of the bracket 13, and does not reach the mount 14. In addition, the stopper 21 prevents collisions of stepping stones and the like during traveling and adhesion of sewage and the like.
And can be stopped by the bracket 13.
The mount 14 can be prevented from being dirty or damaged. Therefore, it is possible to prevent the deterioration of the vibration absorbing ability due to the deterioration of the elastic material such as rubber used for the outer shell of the mount as much as possible.

Next, FIG. 5 shows the shape of a bracket according to another embodiment. Like the bracket 25, the shape of the wall surfaces 26 and 27 can be changed in consideration of the arrangement of the exhaust device of the engine and the temperature of the radiant heat.

[0015]

According to the present invention, the following effects are obtained. The side of the mounting base of the bracket is bent and at least one pair of opposing walls is formed so as to cover almost the side of the mount, so that the mount can be covered in combination with existing stoppers. The bracket itself serves as a mount cover. Therefore, the mount is protected from heat, dirt, and scattered matters that cause the durability of the mount to be reduced, and the number of parts is not increased. The bracket is formed by bending a single plate material, and since this processing is very easy, the cost of parts can be reduced. Also, by forming the shape of the present invention, the rigidity of the bracket itself is also improved.
