Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a mounting device for elastically supporting an internal combustion engine mounted on a vehicle with respect to a body frame of the vehicle.

[Conventional technology]

Conventionally, this type of mounting device is disclosed in, for example,
As described in Japanese Patent No. 64426 or Japanese Utility Model Application Laid-Open No. 63-142440, an insulator made of an elastic material such as rubber provided with an inner cylinder member is provided inside the outer cylinder member. While attaching the member to the vehicle body frame or the internal combustion engine, the bolt is inserted into the inner cylinder member inside the insulator, and a bracket supporting both ends of the bolt is attached to the internal combustion engine or the vehicle body frame, whereby the internal combustion engine is mounted. The elastic body is elastically supported on the vehicle body frame via the insulator.

[Problems to be solved by the invention]

However, when the conventional mounting device attaches the outer cylinder member or the bracket to the internal combustion engine,
Since one attachment lug projects from the internal combustion engine and the outer cylinder member or bracket is fastened to this one attachment lug with bolts, one mounting lug for the internal combustion engine is mounted. Since a large external force for supporting the internal combustion engine acts intensively on the mounting portion of the outer cylinder member or the bracket with respect to the ear piece, not only settling occurs on the mounting portion but also loosening of the bolt. There was a problem that it occurred frequently.

In the present invention, the internal combustion engine is provided with two mounting ear pieces,
The conventional problem is solved by bolting the outer cylinder member or the bracket to the both mounting ear pieces.

However, as described above, the provision of the two mounting lugs on the internal combustion engine and the bolting of the outer cylinder member or the bracket to the two mounting lugs require the space between the two mounting lugs and If there is a dimensional error between the outer seat member or the bracket and the space between the mounting seats for the two mounting ear pieces, the two mounting ear pieces will be damaged when fastening the bolt. Since another problem occurs, the present invention aims to eliminate the problem.

[Means for solving the problem]

In order to achieve this object, the present invention provides: "Inside an outer cylinder member, an insulator made of an elastic material such as rubber having an inner cylinder member is provided, and the outer cylinder member is
While attaching to the body frame or the internal combustion engine, insert a bolt into the inner cylinder member inside the insulator,
In a mounting device in which a bracket supporting both ends of the bolt is mounted on an internal combustion engine or a vehicle body frame, two mounting ear pieces are separated from the internal combustion engine by an appropriate distance between the mounting ear pieces. On the other hand, the outer cylinder member or the bracket is provided with two mounting portions for each of the both mounting ear pieces, and one of the mounting portions is attached to one of the two mounting ear pieces. A first bolt is fastened to one mounting lug, and a bush is attached to the other mounting lug in a direction parallel to the axis of the first bolt. The bush is slidably fitted, and the bush is fastened to the other of the two mounting portions by a second bolt inserted into the bush. "

[Operation] With this configuration, the outer cylinder member or the bracket is
The large external force for supporting the internal combustion engine can be distributed to the two places by being attached to the internal combustion engine with two mounting lugs projecting from the internal combustion engine at appropriate intervals. From this, it is possible to avoid that a large external force for supporting the internal combustion engine acts intensively at the location of one mounting lug as in the conventional case,
It is possible to reliably reduce the occurrence of set in the mounting portion and the occurrence of loosening of the fastening bolt.

In addition, one of the mounting ears formed on the outer cylinder member or the bracket is fastened to the one of the mounting ears protruding from the internal combustion engine with the first bolt. On the other hand, a bush is fastened to the other of the two mounting portions of the outer cylinder member or the bracket with a second bolt, and this bush is connected to the other of the mounting ear pieces of the internal combustion engine. By slidably fitting the ear piece in a direction parallel to the axis of the first bolt, the first bolt is fastened first, and then the second bolt is fastened. In this case, it is possible to prevent the tightening force of the second bolt from acting on one of the mounting lugs.

For this reason, when attaching the outer cylinder member or the bracket to the two attachment ear pieces protruding from the internal combustion engine with bolts, the interval between the two attachment ear pieces in the internal combustion engine and the outer cylinder member or the bracket It is possible to reliably prevent the mounting ear pieces of the internal combustion engine from being damaged due to a dimensional error between the mounting portion and the gap between the mounting portions.

[Effect of the invention]

Therefore, according to the present invention, the outer cylinder member or the bracket in the mount support can be moved toward the internal combustion engine without damaging the two mounting lugs projecting from the internal combustion engine.
It has an effect that it can be securely and firmly attached at two places.
