Abstract

PURPOSE: A structure of an engine mounting bracket enhances the binding capacity or the rigidity thereof by rolling up a steel plate to prepare an insertion space for an insulator and inserting the insulator into the insertion space and simplifies the fabrication thereof. CONSTITUTION: A structure of an engine mounting bracket comprises the first mounting piece(40), the first banding piece(11), the second banding piece(12) and the second mounting piece(41). The first mounting piece(40) has bolt assembly holes(42) formed thereon. The first banding piece(11) is extended from one side of the first mounting piece(40) with being rolled up and has a definite insertion hole(13) formed on the middle thereof. The second banding piece(12) is extended from the end of the first banding piece whose width is tapered more than that of the insertion hole(13) and the extension part thereof passes through an insertion hole of the first banding piece(11) to be extended to the first mounting piece(40) by being rolled. The second mounting piece(41) is opposite to the first mounting piece(40) as the ending part of the second bending piece(12) and has bolt assembly holes formed thereon. Therefore, the structure of the engine mounting bracket inserts an insulator easily, is fixed on a chassis frame more rigidly and shortens a process.

Description

Engine mounting bracket structure

The present invention relates to a structure of an engine mounting bracket for fixing to a chassis frame to absorb and remove vibrations or shocks when the engine is mounted.

In general, the engine mounting is mostly a four-point support system, and both ends of the engine and the transaxle are fixed to the vehicle body, and the engine and the transaxle are fixed by a roll stopper fixed to the front and rear ends of the center member, respectively. It is supposed to perform a dustproof function that prevents transmission to the body.

Referring to the conventional engine mounting structure as shown in FIG. 4, the insulator 2 is fixedly mounted with a bracket 1 fixed to the chassis frame 3, and the insulator 2 is fixed at the center. An assembly hole 21 having a hole into which a bolt can be inserted, a case 22 surrounding the outer circumference of the assembly hole 21, and a rubber damper 23 are inserted between the assembly hole and the case.

In the conventional engine mounting, when vibration is generated in the engine, the vibration is applied to the engine mounting insulator, and when the engine mounting insulator receiving the vibration is moved left and right, the vibration is prevented from being transmitted to the vehicle body by stoppers installed at both sides thereof.

However, such an engine mounting bracket is manufactured by press-processing metal steel and then welding, or by casting and casting a cast iron or aluminum material, and then machining it. An insulator manufactured by through holes in the bracket is manufactured. It is pointed out that the manufacturing process is complicated and laborious because it must be pressed to insert.

The present invention has been proposed in order to solve the problems of the engine mounting bracket as described above, by forming a steel plate in a long strip shape and then rolled up the steel plate to provide an insertion space of the insulator, and inserting and fixing the insulator into the insertion space It is an object of the present invention to be able to reduce the production cost according to the simplification of the manufacturing while improving the bonding force or rigidity.

The present invention as a means for achieving the above object

In the engine mounting structure for supporting the engine by inserting the insulator into the bracket fixed to the chassis frame,

A first fastening part in which a bolt assembly hole is formed,

A first bending part extending in a long direction to one side of the first fastening part, and having an insertion hole formed at a predetermined interval on a center line thereof and wound in a circle;

A second banding portion extending from the end portion of the first bending portion to a width smaller than that of the insertion hole, the extension portion of which extends through the insertion hole of the first bending portion to a first fastening portion. Wealth,

An end of the second bending portion is opposed to the first fastening portion, characterized in that the configuration consisting of a second fastening portion formed with a bolt assembly hole.

41: second fastening portion

1 is a view showing an embodiment structure according to the present invention, Figure 2 is an exploded view of a bracket according to the present invention, 10 is shown Expanded bracket before molding and 20 is an insulator.

3 is a perspective view of a bracket according to the present invention.

As shown in FIG. 2, the bracket 10 is extended to one side of the first fastening part 40 in which the bolt assembly hole 42 is formed, and the insertion hole 13 of a predetermined interval penetrates the first bending part through the center line. (11) is formed, and the 2nd bending part 12 of the width | variety smaller than the width | variety of an insertion hole is extended on the extension line in the shape extended.

The unfolded bracket 1 is passed through the end of the second bending portion 12 through the insertion hole 13 of the first bending portion 12, as shown in FIG. When the end of the 2 bending portion 12 is extended to the first fastening portion 40, the insertion space 15 into which the insulator 20 can be inserted is rounded.

Next, when the second bending portion 41 is welded to the end portion of the rounded bracket to face the first coupling portion 40 of the first bending portion, the bracket according to the present invention is completed.

Referring to the operation of the present invention configured as described above is as follows.

After inserting the insulator into the insertion space 15 of the bracket formed as described above without additional pressing, tightening the bolt after tightening the bolt to the chassis frame 30, the first and second banding parts that are loosened are pressed together. The insulator is firmly fixed to facilitate the mounting of the engine.

Therefore, if the bracket is manufactured as described above, instead of pressing and inserting the insulator into the conventional bracket, the insert can be easily inserted, and it can be fixed and fastened to the chassis frame more firmly, reducing the cost and reducing the weight of the bracket by shortening the process. give.
