[0001] The present disclosure relates generally to a field of a coupling device for an agricultural vehicle. More specifically, it pertains to a simple and effective coupling device which prevents vibration, noise, and misalignment between a shaft of motor and crankshaft of an engine of the agricultural vehicle.

BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Coupling are devices used to mechanically connect two coaxial shafts to transmit power from drive shaft to driven shaft in an agricultural vehicle such as tractors. Coupling of shaft is a process of engaging a crankshaft of an engine with shaft of motor to transmit power, energy, torque, motion, or force from crankshaft of an engine to shaft of motor, and/or shaft of motor to crankshaft of an engine. Primary purpose of coupling device is to connect two components of rotating shafts, while transmitting torque from shaft of motor to crankshaft of an engine. Various type of coupling device includes sleeve coupling, split muff coupling, flange coupling, bush pin coupling, gear coupling, fluid coupling, and the like.
[0004] Continuous increase of driveline performance of tractors is a foremost target of all agricultural vehicle manufactures. In an agricultural vehicle shaft of motor (drive shaft) is connected by coupling device with crank shaft (driven shaft) of an engine, such that coupling device enables torque transmission from shaft of motor to crankshaft of an engine. Similarly, crankshaft of an engine is connected to shaft of motor by a coupling device which enables crankshaft to transmit torque to shaft of motor.
[0005] Existing coupling device, in agricultural vehicle, enables misalignment of the shafts, thereby effecting velocity and acceleration of crankshaft of engine, and/or shaft of motor. Misalignment can be angular, parallel, and skew, which increases failure chances of crankshaft of an engine and shaft of motor. Misalignment overloads crankshaft of an engine and shaft of motor, thereby decreasing overall life of crankshaft of an engine and shaft of motor. Moreover, misalignment of crankshaft of an engine and shaft of motor reduces torque value of coupling device.
[0006] In an existing technique, coupling device is used to connect drive shaft and driven shaft, and the drive shaft is provided with a first shaft part. The first shaft part includes a first universal joint and a first profiled tube. The driven shaft is provided with a second shaft part. The second shaft part includes a second universal joint and a second profiled tube. Major disadvantage with an existing technique is that vibrations between drive shaft and driven shaft increases, which escalate power losses due to presence of universal joints. Another disadvantage with an existing technique is that coupling device require more space, thereby increasing cost and decreasing efficiency of coupling device.
[0007] There is, therefore, a need in the art to provide a simple, compact, and a cost effective coupling device for an agricultural vehicle which absorbs vibration, noise, and misalignment of the crankshaft of an engine and shaft of motor.

OBJECTS OF THE INVENTION
[0008] A general object of the present disclosure is to provide an efficient and economical solution to prevent vibrations, noise, and misalignment between shaft of motor and crankshaft of an engine of an agricultural vehicle.
[0009] An object of the present disclosure is to provide a coupling device for an agricultural vehicle to absorb any unwanted vibrations and noise between shaft of motor and crankshaft of an engine.
[0010] Another object of the present disclosure is to provide a coupling device for an agricultural vehicle which minimizes power losses between shaft of motor and crankshaft of an engine when the shafts are running on high speed.
[0011] Another object of the present disclosure is to provide a coupling device for an agricultural vehicle which requires less space for providing optimum contact of coupling device with shaft of motor and crankshaft of an engine.
[0012] Another object of the present disclosure is to provide a coupling device for an agricultural vehicle which prevents misalignment between drive shaft and driven shaft, such that the velocity and acceleration of driven shaft is not affected.
[0013] Another object of the present disclosure is to provide a coupling device for an agricultural vehicle which protects drive shaft and driven shaft against overloads, thereby increasing overall life of drive shaft and driven shaft.
[0014] Another object of the present disclosure is to provide a coupling device for an agricultural vehicle which accommodate high torque value.
[0015] These and other objects of the present invention will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings.

[0079] In an embodiment, the coupling device 100 can be configured with an external member 204, and the connecting member 206 (interchangeably can be referred to as flange, herein). The external member 204 can include but not limited to pulley, wheel, block, and the like. The flange 206 can be configured with the external member 204 such that rotation of the external member 204 enables rotation of the flange 206. The external member 204 can be configured with the connecting member 206 such that the rotation of the connecting member 206 enables rotation of the crankshaft of an engine. In another embodiment, the high speed rotation of the crankshaft of an engine enables rotation of the flange 206 and the external member 204. The coupling device 100 can avoid misalignment between the shaft of motor 202 and the crankshaft of an engine, such that the velocity and acceleration of the shaft of motor 202 and the crankshaft of an engine cannot be affected.
[0080] In an exemplary embodiment, the external member 204 can be configured with the second outer ring 138, the damping member 114, and the second inner ring 132 of the coupling device 100, such that rotation of the external member 204 enables rotation of the coupling device 100 thereby transmitting torque from the crankshaft of an engine to the shaft of a motor 202, and/or transmitting torque from the shaft of a motor 202 to the crankshaft of an engine.
[0081] In an embodiment, the coupling device 100 can be used for heavy duty application which provide optimum contact with the crankshaft of an engine and the shaft of a motor 202 to accommodate higher torque values, while reducing power loss and minimizing effects of misalignment. The coupling device 100 can protect the crankshaft of an engine and the shaft of a motor 202 against overload and increases service life of the crankshaft of an engine and the shaft of a motor 202, resulting in higher productivity and profitability.
