PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the invention and the manner in which it is to be performed.


FIELD OF INVENTION
The present invention is related to engine mounting system and more particularly to engine mounting system integrated with anti roll bar and cab tilt mechanism for supporting and mounting the power train of a vehicle.
BACKGROUND OF INVENTION
Generally engine mounting brackets are used for supporting and mounting the power train. The said mounting bracket provides the means to transfer the vibration which is coming from the engine to the frame structure of vehicle. Normally in the existing engine mounting system the cross member is provided for transferring the said vibration coming from the engine to the frame structure for vehicle. One of the major drawback of the above mentioned engine mounting system is that the said cross member often tends to fail in the field condition. The failure of the said cross member in field, leads to total reworking of whole engine mounting cross member assembly which is costly and time consuming process.
OBJECTSOF INVENTION
The main object of the present invention is to provide engine mounting system for vehicle.
Another object of the invention is to provide an engine mounting system integrated with anti roll bar and cab tilting mechanism for vehicle.

Engine mounting system, in accordance with this invention, wherein said first engine mounting bracket member is connected by lock plate for preventing the rotation of the nut used for tightening the said rubber insulator.
Engine mounting system, in accordance with this invention, wherein said first engine mounting bracket member comprises mounting means for tilting mechanism for cab.
3

Engine mounting system, in accordance with this invention, wherein said second engine mounting member comprises protrusion for mounting cab tilt cylinder.
Engine mounting system as claimed in claim 1 wherein said second engine mounting member comprises holes for mounting anti roll bar.
Vehicle comprising engine mounting system integrated with anti roll bar and cab tilting mechanism in accordance with preceding claims.
BRIEF DESCRIPTION OF INVENTION
In accordance with present invention, engine mounting system comprises; first engine mounting bracket members mounted on engine for holding the power train, second engine mounting bracket member mounted on frame for holding the power train, Rubber insulator typically at front of engine, said rubber insulator comprising two rubber members which are sandwiched between two metallic plates.
The said first Engine mounting bracket member is fitted on the mounting face of the said engine and said rubber insulator rests on other side of the mounting face of the of the said first engine mounting bracket member. The said rubber insulator which is adapted to perform the main function of dampening the vibrations between the engine and frame structure is attached to the second engine mounting bracket member on said frame member. The said second engine mounting bracket member is fitted on the said frame member thus providing the necessary support to engine.
The said first engine mounting bracket member is connected with the help of lock plate for preventing the rotation of nut used for tightening the said rubber insulator

DETAILED DESCRIPTION OF INVENTION
Referring now to the drawings wherein the showings are for the purpose of illustrating a preferred embodiment of the invention only, and not for the purpose of limiting the same.
Now referring to the figure-01 to 05, In accordance with present invention, engine mounting system comprises; first engine mounting bracket member (1) mounted on engine for holding the power train, second engine mounting bracket member ( 5) mounted on said frame member (3) for holding the power train, Rubber insulator (4) is
5

provided typically at front of engine, said rubber insulator comprising two rubber member which are sandwiched between two metallic plates.
The said first engine mounting bracket member (1) is fitted on the engine on mounting face of the said engine and said rubber insulator (4) rests on other side of the mounting face of the of the said first engine mounting bracket member (1). The said rubber insulator (4) which is adapted to perform the main function of dampening the vibrations between the said engine and said frame structure which is attached to the said second engine mounting bracket member (5) on said frame member (3). The said engine mounting bracket member (5) is fitted on the said frame member (3) thus providing the necessary support to the said engine.
The said second engine mounting bracket member (5) comprises hole (6) provided therein for mounting antiroll bar and protrusion member (7) for mounting cab tilt cylinder.
The first engine mounting bracket member (1) is connected with the help of lock plate (2) for preventing the rotation of nut used for tightening the said rubber insulator (4).
The second engine mounting bracket member (5) is provided for the supporting the said engine from inside and for supporting the cab tilt cylinder from outside and to take the loads coming from roads and wheel movement through the Anti Roll Bar mounting.
The second engine mounting bracket member (5) primarily supports the said engine and gearbox power train from inside of the said frame member (3).
6

The said first engine mounting bracket member (1) also supports the Anti Roll Bar linkage of front axle and tyre assembly of a vehicle.
The said first engine mounting bracket member (1) transfers the engine vibrations coming from engine through said rubber isolator (4) to the said frame member (3) and said first engine mounting bracket member (1) also prevents the vibrations coming from road directly going to said engine through said rubber insulator (4) and thus helps to prevent the damage to said engine due to excessive vibration in running condition.
The said first engine mounting bracket member (1) carries the torque load coming from road through Anti Roll Bar of a vehicle.
The foregoing description is a specific embodiment of the present invention. It should be appreciated that this embodiment is described for purpose of illustration only, and that numerous alterations and modifications may be practiced by those skilled in the art without departing from the spirit and scope of the invention. It is intended that all such modifications and alterations be included insofar as they come within the scope of the invention as claimed or the equivalents thereof.
