,TagSPECI:TECHNICAL FIELD
Embodiments of the present disclosure relates to an engine mount bracket assembly of an automobile. More particularly, embodiments relates to an improved engine mount bracket assembly which provides good vibration isolation, and limits the engine displacement in all directions.

BACKGROUND OF DISCLOSURE

Vibration producing in engine is transferred to cab through chassis frame, which provide discomfort riding to the driver and passenger. Engine rubber mount is placed at the interface of the engine and chassis frame, which is used to provide vibration isolation. On rough road couple with engine vibration, considerable engine displacement occurs, which produce riding discomfort and also affects other aggregate locates in close vicinity of the engine.

Generally, the engine room includes an engine mount which prevents the direct transmission of the vibration and shock originated from the power train to the vehicle body, to reduce the vibration and noise and improve the passengers' comfort.

The conventional vehicle engine mounts comprises an engine bracket fixed to a power train, a mounting rubber bracket engaged with the engine bracket; a rubber bush fixed at the mounting rubber bracket; and a body bracket for connecting the mounting rubber bracket with the mounting rubber bush to a chassis frame. Each of the body bracket and the engine brackets are fixed at the frame forming the vehicle body and the power train, and the body bracket and the engine bracket are engaged with the mounting rubber having the mounting rubber bush via the bolts, so that the mounting rubber bush absorbs the vibration and shock originated from the power train.

The conventional engine mounts requires many assembly components, such as the mounting rubber with the mounting rubber bush, the engine bracket, the body bracket and so on, in order that the mounting rubber bush absorbs the vibration and shock, which results in an increase in the assembly components and assembly workability and decreases the manufacturing costs. Further, since the large installation space is needed, it is difficult that the engine mount is installed at a desired position, without interference with the other installations.

Further, the other type of conventional engine mounts comprises chassis frame bracket adapted to be mounted on the chassis, rubber mount connected to the chassis mount bracket. The rubber mount comprises a through hole for connecting to the engine bracket. In this type of engine mounts the rubber bush is not supported from all the directions and the motion of the rubber mount is not limited in certain directions. These results in inefficient absorption of the vibrations generated by the engine and the vehicle due to road bumps, leading to discomfort inside the cabin, and also results in displacement of engine in certain directions.

In light of the foregoing discussion, it is necessary to develop an improved engine mount bracket assembly which provides good vibration isolation, limits the engine displacement in all directions, and has less number of components to overcome the limitations stated above.
