[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine mount base structure provided on a vehicle body for receiving an engine mount insulator attached to the engine when the engine is mounted on the vehicle body.

[0002]

2. Description of the Related Art As such an engine mount pedestal structure, for example, a structure described in Japanese Utility Model Laid-Open No. 63-77823 has been known.

In this engine mount pedestal structure, a through hole is formed in an engine mount bracket which is mounted on a vehicle body and receives an engine mount insulator, and a corresponding projection of the engine mount insulator is made to penetrate into this hole to mount the engine mount on the engine mount. It is positioned with respect to the bracket. And as the above-mentioned hole in this kind of engine mount pedestal structure, there are those for simply positioning the insulator,
In some cases, the insulator is finally positioned at a predetermined position while guiding the insulator to a predetermined position during the work of mounting the insulator on the pedestal.

As another engine mount pedestal structure, one shown in FIG. 4 has been proposed. This engine mount pedestal structure is a pedestal structure in which a receiving plate 11 for receiving an engine mount insulator and a vertical plate 13 for attaching this receiving plate to a vehicle body member 12 are integrally connected. 11, a pair of bent tongue pieces 11a projecting from
The insulator is positioned with respect to the receiving plate 11 by engaging the corresponding side edge of the engine mount insulator with a and supporting the load of the engine.

[0005]

In the former engine mount pedestal structure, the positioning of the engine mount insulator can be performed regardless of the type of the through hole provided for penetrating the projection of the engine mount insulator. There is a problem that the engine is not perfect and the mounting position of the engine is easy.

In the latter engine mount pedestal structure,
The positioning of the engine mount insulator is not sufficient, and in addition, a step of bending the tongue piece 11a during the manufacture of the receiving plate 11 is indispensable, so that an increase in manufacturing costs cannot be avoided. Further, the bent tongue 11a must support the load from the engine in the thickness direction thereof, and the tongue 11
To increase the thickness of the tongue piece 11a in order to have the deformation strength a, the receiving plate 11 must be made thicker overall, which is disadvantageous both in weight and cost.

An object of the present invention is to provide an engine mount pedestal structure which does not cause these problems.

[0008]

SUMMARY OF THE INVENTION For this purpose, the present invention is directed to a projection which is integrally connected to a receiving plate for receiving an engine mount insulator and a vertical plate for attaching the receiving plate to a vehicle body member. In the engine mount pedestal structure, which is capable of positioning the engine mount insulator on the receiving plate and supporting the engine load applied to the engine mount insulator, the protrusion extends in the direction of the engine load to be supported by the protrusion. A polygonal projection having a predetermined width provided integrally with a plate portion of the existing vertical plate, penetrating the receiving plate, projecting from the receiving plate, and penetrating into the engine mount insulator. And the engine load to be supported in the width direction of the projection by the projection. It is characterized in that fitted to the direction of.

[0009]

When the engine is mounted, the engine mount insulator is received on the receiving plate. At this time, the protrusion protruding from the receiving plate penetrates into the engine mount insulator, positions the insulator on the receiving plate, and supports the engine load applied to the engine mount insulator. By the way, first, the projection penetrates the engine mount insulator and positions it in all directions, so that the positioning is complete. In particular, such a projection is integrally formed and provided on a plate portion of a vertical plate extending in the direction of the engine load to be supported by the projection, and penetrates through the receiving plate and projects from the receiving plate. It is composed of polygonal projections of a predetermined width provided to penetrate the mount insulator, and the width direction of the projections matches the direction of the engine load to be supported by these projections, so it is not necessary to bend the projections and bend them Since the process can be eliminated and the thickness of the projections, and hence the thickness of the vertical plate, does not need to be increased, it is very advantageous in terms of cost and weight.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows an embodiment of the engine mount pedestal structure of the present invention. In the drawing, the same parts as those in FIG. 4 are indicated by the same reference numerals. The receiving plate 11 receives an engine mount insulator 14, which will be described later with reference to FIG. 3, and a pair of bolt holes 11b are formed in the receiving plate 11 to mount the insulator. The vertical plate 13 is integrally connected to the receiving plate 11 by welding.
To be attached to

The vertical plate 13 further includes a load α from the engine.
A pair of rectangular projections 13a each having a predetermined width and penetrating through the elongated hole 11c of the receiving plate 11 and projecting from the plate portion (the left and right plate portions in FIG. 1) extending in the direction along the direction (see FIG. 2) are integrally formed. Formed. The projecting length of these square projections 13a is also a length that penetrates through a long hole 15a formed in the base plate 15 of the engine mount insulator 14 that is in contact with the receiving plate 11, as shown in FIG.
At the tip of the projection 13a, a corner is cut off to form a tapered surface 13b to facilitate the penetration into the elongated hole 15a.

The square projection 13a is connected to the engine load α.
Is formed integrally with the plate portion (the left and right plate portions in FIG. 1) of the vertical plate 13 extending in the direction along the width of the rectangular projection 13a, so that the width direction of the square projection 13a matches the direction of the engine load α to be supported thereby. In other words, the rectangular projection 13a is made as close as possible to the insulator mounting bolt hole 11b.

Here, the engine mount insulator 14 is configured as shown in FIG. 3 corresponding to the above-described engine mount base structure. That is, the insulator 14
Consists of a base plate 15 and an upper plate 16 opposed thereto and an insulator rubber 17 bonded and interposed between the plates as usual, and a bolt hole aligned with the bolt hole 11b of the receiving plate 11 is formed in the base plate 15. 15b is formed, and bolts 18 for mounting the engine are implanted in the upper plate 16. The base plate 15 is further provided with a long hole 15a through which the square projection 13a passes.

The operation of the above embodiment will now be described. First, in practical use, the receiving plate 11 is mounted on the vehicle body member 12 via the vertical plate 13. Then, the insulator 14 is attached to an engine (not shown) via the bolt 18 and the engine is lowered toward the mounting position. Thereby, the long hole 15a formed in the base plate 15 of the insulator 14 is easily fitted into the protrusion 13a while being guided by the tapered surface 13b formed in the square protrusion 13a of the vertical plate 13 as shown in FIG. 1
4, so that the engine can be positioned. In this position, the insulator 14 and thus the engine are mounted on the receiving plate 11 by bolts (not shown) inserted into the holes 11b and 15b.

Since the positioning of the insulator 14 by the projection 13a is performed in all directions, the positioning is more complete.
Since a is arranged close to the bolt hole 11b, it is further promoted. In addition, when the vertical plate 13 is welded to the receiving plate 11, the projection 13a regulates the relative position between the two, so that the work can be easily performed during the welding.

Since the projections 13a need only be formed on the vertical plate 13 so as to penetrate the receiving plate 11, there is no need to bend the projections, so that a bending step can be eliminated and the production cost is greatly reduced. is there. Further, since the projection 13a is provided to receive the load of the engine in the width direction, it is not necessary to increase the thickness of the projection 13a, that is, the thickness of the vertical plate 13, and this is also very advantageous in cost. It is also advantageous in weight.

[0017]

As described above, in the engine mount base structure of the present invention, the receiving plate 11 for receiving the engine mount insulator 14 and the vertical plate 13 for attaching the receiving plate to the vehicle body member 12 are integrally connected. Assuming an engine mount pedestal structure in which the projection 13a protruding from the receiving plate 11 positions the engine mount insulator 14 on the receiving plate 11 and can support the engine load α applied to the engine mount insulator 14, The protrusion 13a
The projection is formed integrally with a plate portion of a vertical plate 13 extending in the direction of an engine load α to be supported by the projection, and penetrates through the receiving plate 11 to protrude from the receiving plate. The projection 13a has a predetermined width and is provided so as to penetrate into the shaft. The width direction of the projection 13a matches the direction of the engine load α to be supported by the projection. be able to. That is, first, the projection 13a penetrates into the engine mount insulator 14 and positions it in all directions, so that the positioning of the insulator can be completed. Also such protrusion 1
3a is constituted by polygonal projections formed as described above, and the width direction of the projections is made to coincide with the direction of the engine load α to be supported by the projections. And because it is not necessary to increase the thickness of the projections, and hence the thickness of the vertical plates,
This is very advantageous in terms of cost and weight.
