Embodiments of the present disclosure discloses a power take-off unit for driving an agricultural implement in the second operational configuration of the modular vehicle.
BACKGROUND
With increase in population, there is substantive increase in agricultural activities to meet the food demand. Inculcation of technology in the form machineries has been growing at a substantive rate to improve efficiency and effectiveness of the agricultural activities, thereby reducing labour, and improving yield. Once such widely adapted machinery in performing agriculture related activities is a tractor, which is substantially adapted to perform ploughing and the like. However, due to high investment and maintenance cost, usage of tractors is limited only for large-scale agricultural activities. Also, because of the bulky structure, usage of tractors for small scale agricultural activities is limited.
Considering the above, mini tractors and tillers have evolved to perform small scale agricultural activities. However, such systems also require higher investment and maintenance costs. Further, with the advancements in technology, two wheelers such as motorized scooters, motorcycles, etc., have been modified to perform small scale agricultural activities. Conventionally, two wheelers require extensive modification for adapting to perform agricultural activities. Such modification broadly include, removing the drive wheel, incorporating rigid power transmitting units, welding or brazing the agricultural implement to the two-wheeler and the like. Conventional power transmitting units are adapted to draw power directly from a sprocket extending from the gearbox of the two-wheeler. Such power transmitting units are complex, bulky and require extensive modification of the two-wheeler, making the conversion expensive, requiring considerable time and physical efforts. Such modification, especially rigid power transmitting unit, to

the two-wheeler makes the two wheeler solely for performing agricultural activities, thereby deviating from the two wheeler's intended function of commuting, which is undesired.
The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the prior art.

In an embodiment, the driven member (113) may be coupled to a gearbox (105) of the agricultural implement (102). The gearbox (105) may be configured to provide necessary torque to the plurality of wheels (106) of the agricultural implement (102), corresponding to actuation (thus, rotation) of the driven member (113). Additionally, the power take-off unit (109) may include a power transfer member (114), which may extend between the driving member (112) and the driven member (113). In other words, the power transfer

member (114) may be supported by the driving member (112) and the driven member (113) and may be structured to transfer rotational movement of the driving member (112) to the driven member (113).
In an illustrated embodiment, the driving member (112), the driven member (113) are illustrated as a pulley and the power transfer member (114) is illustrated as a belt. However, the same cannot be construed as a limitation. In some embodiments the driving member (112) and the driven member (113) may be but not limiting to sprocket, gear and the like, and the power transfer member (114) may be but not limiting to a chain, a gear train and the like.
In an embodiment, the driving member (112) and the driven member (113) may include different diameters to obtain different drive ratios, in order to vary torque being transferred to drive the agricultural implement (102).
In an embodiment, as seen in Figure 1 the modular vehicle (100) may include a casing (120), which may be connectable to the body structure (110), such that the casing (120) receives a portion of the shaft (111) extending from the hub (118) of the drive wheel (117). The casing (120) may be defined with a plurality of projections (121) to support the power transfer member (114) [as seen in Figure 6], when the modular vehicle (100) is being operated in the first operational configuration.
In an operational embodiment, the modular vehicle (100) may be configured to generally operate in the first operational configuration i.e., as a two-wheeler (101) for commuting. Based on the requirement, the modular vehicle (100) may be operable in the second operational configuration i.e., a three-wheeled or four-wheeled configuration to perform agricultural activities. In order to operate the modular vehicle (100) in the second operational configuration, the agricultural implement (102) may be attached to the body structure (110). In an embodiment, attaching of the agricultural implement (102) to the body structure (110) may result in raising of the drive wheel (117) above a ground level and the modular vehicle (100) may be supported by the plurality of wheels (106) of the agricultural implement (102), and the maneuvering wheel [not shown in Figs] of the two-

wheeler (101). Once the agricultural implement (102) is attached to the body structure (110), the power take-off unit (109) may be activated to drive the agricultural implement (102). In an embodiment, activating the power take-off unit (109) may include connecting the power transfer member (114) between the driving member (112) and the driven member (113). During operation, corresponding to rotation of the driving wheel (117), the shaft (111) may also rotate as a result of which the driving member (112) may rotate. Relative to rotation of the driving member (112), the power transfer member (114) may transfer the rotational motion to the driven member (113), thereby driving the agricultural implement (102).
In an embodiment, to operate the vehicle back to the first operational configuration, the power transfer member (114) may be disconnected between the driving member (112) and the driven member (113), and the agricultural implement (102) may be disengaged from the body structure (110). Upon disengaging the agricultural implement (102), the driving wheel (117) may contact the ground and, thus facilitates in operating the modular vehicle (100) in the first operational configuration.
In an embodiment, configuration of the power take-off unit (109) aids in easy switching of the modular vehicle (100) between the first operating configuration and the second operating configuration.
In an embodiment, configuration of the power take-off unit (109) is simple compact in construction and aids efficient power transmission.
