Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine mount structure.

[0002]

2. Description of the Related Art Some engine mounts use a liquid-sealed elastic body. This liquid-sealed elastic body has two liquid chambers communicating with each other through a narrow passage, and a liquid exhibits a vibration damping function by moving between the liquid chambers through the narrow passage. It is attached to the vehicle body by a bracket (see Japanese Utility Model Laid-Open No. 4-39446 and Japanese Patent Laid-Open No. 5-296284). That is, the bracket includes a main body that supports the liquid-sealed elastic body and a support leg that is welded to the main body and connected to the vehicle body, and the liquid-sealed elastic body is elastically displaced in the main body of the bracket. It is usual to weld a stopper that comes into contact with the liquid-sealed elastic body and restricts elastic displacement above a certain level when performing the above-mentioned operation.

[0003]

However, in the engine mount structure as described above, since the main body of the bracket and the supporting leg are welded to each other, the overlapping portions are increased and the shape or structure is complicated, and the weight is heavy. Also, the number of manufacturing steps increases and the manufacturing cost also increases. Moreover, when the stopper is welded to the body of the bracket, the above problem becomes more remarkable.

[0004]

It is characterized in that it comprises a mounting portion that is coupled to.

In the case of the present invention, since the main body is formed in a tubular shape, the liquid-sealed elastic body can be held so as to be wrapped from the entire circumference thereof, which is advantageous in obtaining high support strength. Further, since the pair of support legs have mounting portions that project in the cylinder length direction from one opening edge of the tubular body and extend outward on both sides so as to be separated from each other, the support legs are incorporated in the elastic body in the body. Is not a hindrance, and the support legs can be easily connected to the engine or the vehicle body.

(Invention of Claim 3) The present invention provides the engine mount structure according to claim 1, wherein the liquid-sealed elastic body is further elastically displaced when elastically displaced.

The holder is welded, and the liquid-sealed elastic body is adhered to the holder.

According to the present invention, since the liquid-sealed elastic body is supported by the main body plate via the cylindrical holder, the main body plate, the support legs and the stopper are all U-shaped and simple. The support of the liquid-sealed elastic body to the body plate becomes relatively strong. Further, the main body plate, the supporting legs and the stopper can be made in a simple overall shape, and the welding can be performed only by welding the main body plate and the cylindrical holder, which facilitates the production.

(Invention of Claim 5) According to the present invention, in the engine mount structure according to claim 3, the main body is composed of a pair of main body plates facing each other, and the stoppers are provided on both main body plates.

In the welding in this case, the holder 3 is placed between the body plates 5 and 5 of the bracket 2, and the abutting portion 3a of the steel plate of the holder 3 is formed into the slit 5 of one body plate 5.
The welding material is fitted to the abutting portion 3a so that the slit 5a is closed by the welding material buildup 9 as shown in FIG. 3 and 3 are connected. The slit 5a of the other body plate 5 of the bracket 2 is also filled with a welding material so that the body plate 5 and the holder 3 are welded.

In the liquid ring type elastic body 4, 11
Is a rubber portion whose peripheral surface is vulcanized and adhered to the inner surface of the holder 3, 12 is a stopper plate which is attached to the top of the rubber portion 11 via an anchor 13 and is vulcanized and adhered to the rubber portion 11, 14 Is an orifice member having a first liquid chamber 15 formed between it and the lower surface of the central portion of the rubber portion 11, 16 is a diaphragm having a second liquid chamber 17 formed between it and the lower surface of the orifice member 14, and 18 is the diaphragm 16 described above. The holding ring is press-fitted into the holder 3 from below to be held by the holder 3, and the peripheral edge of the diaphragm 16 is sandwiched between the holding ring 18 and the inner peripheral surface of the holder 3.

A mounting bolt 19 for connecting to the engine is provided on the upper surface of the stopper plate 12 so as to project upward, and a stopper for the bracket 2 when the liquid-sealed elastic body 4 undergoes excessive elastic deformation. A stopper rubber 20 that abuts 6 is fixed. Also, the bracket 2
The stopper 6 is formed with a notch 6a for allowing the engine to be connected to the mounting bolt 19.

The orifice member 14 is formed by combining two metal plate members to form an annular passage 14a. The upper metal plate member has a small-diameter communication hole connecting the first liquid chamber 15 and the annular passage 14a. Is formed, and the second metal plate also has a second
A small-diameter communication hole that connects the liquid chamber 17 and the annular passage 14a is formed. The two communication holes are provided at positions that are opposed to each other in the diameter direction of the annular passage 14a (not shown).
