Embodiments of the present disclosure discloses a power take-off unit for driving an agricultural implement in a second operational configuration of the modular vehicle.
BACKGROUND
With increase in population, there is substantive increase in practicing of agricultural activities to meet the food demand to supply balance. Inculcation of technology in the form of agricultural supplementing machineries has been growing at a substantive rate to improve efficiency and effectiveness of the agricultural activities, thereby reducing labour while improving yield. Once such widely adapted machinery in performing the agricultural activities is a tractor, which is generally 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 in small scale agricultural activities is limited.
Considering the above, mini tractors and tillers have been developed to support and perform small scale agricultural activities. However, such vehicles also require comparatively higher investment and/or 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 wheeled vehicles, or commonly referred to as "two wheelers", require extensive modification for adapting and performing the 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 the following detailed description of the embodiments of the disclosure, reference is made to the accompanying figures that form a part hereof, and in which the modular vehicle is shown by way of illustrating specific embodiments of the present disclosure may be practiced. These embodiments are described with sufficient details to enable those skilled in the art to practice the disclosure, and it is to be understood that other embodiments may

Reference will now be made to the exemplary embodiments of the disclosure, as illustrated in the accompanying drawings. Wherever possible, same numerals have been used to refer to the same or like parts. The following paragraphs describe the present disclosure with reference to Figures. 1 to 4.
Figure. 1 illustrates an exploded view of a modular vehicle (100), which may be selectively operable in one of a first operational configuration and a second operational configuration. In an embodiment, the first operational configuration may correspond to two-wheeled configuration of the modular vehicle (100) for commuting, and the second operational configuration may correspond to three-wheeled or four-wheeled configuration of the modular vehicle (100) for performing agricultural activity. As an example, the agricultural activity may be including, but not limiting to ploughing, bund forming, and the like. As seen in Figure. 1, the modular vehicle (100) may be a two-wheeler (101), which may facilitate in operating the modular vehicle (100) in the first operational configuration. The two-wheeler (101) may include a body structure (110), which may be supported and extending from a front end to a rider's seat (114) along a longitudinal length. The body structure (110) may be configured to support a prime mover, rider's seat (114), provide storage space and other subsidiary components. Further, the body structure (110) may be supported by a drive wheel (113) and a maneuvering wheel. In an embodiment, the drive wheel (113) may be a rear wheel and the maneuvering wheel may a front wheel of the modular vehicle (100). The drive wheel (113) may be configured to receive power from the prime mover for operating (thus, driving) the modular vehicle (100). In an embodiment, the two-wheeler (101) may be including, but not limiting to, an electric vehicle or IC vehicle. Alternatively, the two-wheeler (101) may embody any other ridden vehicle, such as, electric motorcycle, etc., without limiting the scope of the present disclosure. As apparent from Figure. 1, the modular vehicle (100) may further include an agricultural implement (102), which may be detachably attached to the body structure (110), based on the requirement.

Turning to Figure. 3, the agricultural implement (102) may include a frame structure (103), defined with a plurality of extensions (104). The plurality of extensions (104) may be configured to removably connect with the body structure (110) of the modular vehicle (100). In an embodiment, the agricultural implement (102) may be removably connected to the body structures by means including, but not limiting to, fasteners. Further, the plurality of extensions (104) includes at least two set of extensions, namely, a first pair of extensions (104a) are defined below a second pair of extensions (104b). The first pair of extensions (104a) are configured to engage the agricultural implement (102) with the body structure (110) to engage a portion of the agricultural implement (102) with the drive wheel (113) and render the vehicle (100) modular. On engagement, the agricultural implement (102) is selectively displaced to lift the drive wheel (113) off the terrain (i.e., vertically from a horizontal ground) so that, the second pair of extension (104b) is coupled to the body structure (110) of the vehicle (100) for allowing movement of the vehicle (100) through the wheels (106) of the agricultural implement (102).
Further, the frame structure (103) may be supported by a plurality of wheels (106), where the plurality of wheels (106) are connected to an axle (107), which includes a differential (108). Furthermore, the agricultural implement (102) may include a gearbox (105), which is configured to provide desired torque for maneuvering the plurality of wheels (106), when the modular vehicle (100) is being operated in the second operational configuration. In an illustrated embodiment, agricultural implement (102) depicted is adapted for ploughing and the same should not be construed as a limitation, since the any agricultural implement (102) may be attached to perform different agricultural activities.
In an embodiment, attaching the agricultural implement (102) to the body structure (110) may operate the modular vehicle (100) in the second operational configuration [as seen in Figure. 2]
Referring to Figure 3, the agricultural implement (102) may include a frame structure (103), defined with a front portion (103a) and rear portion (103b). The front portion (103a) may include a first portion (116) and a second portion (117). The front portion (116) of the

agricultural implement (102) may be configured to removably connect with the body structure (110) of the modular vehicle (100). In an embodiment, the agricultural implement (102) may be removably connected to the body structure (110) by means including but not limiting to fasteners.
In an embodiment the first portion (116) may comprise a plurality of extensions (104) extending from a central portion (118) of the agricultural implement (102). The central portion (118) [as seen in Figure 3] of the agricultural implement (102) connects the front portion (103a) and rear portion (103b) of the agricultural implement (102). The first portion (103a) is profiled to resemble a triangular structure and includes a first aperture (104a) at its tip. The tip is basically defined a point where two vertexes of the triangle meet each other. The first aperture (104a) may be located anywhere proximate to the tip of the triangle. The first portion (116) extends in an upward direction with respect to the second portion (117).
The second portion (117) forms the lower part of the front portion (103a) and may include a second aperture (120). The second portion (117) connects with pluralities of wheels (106), more particularly, to the axel of the wheel and the entire structure of the agricultural implement (102) is supported by the pluralities of wheel (106). The rear portion (103b) of the agricultural implement (102) may include an agricultural tool (120) [as seen in Figure 2] which is having plurality of conical blades (119) [as seen in Figure 4] and is configured to drawn over soil to turn it over and cut furrows in preparation for the planting of seeds and performing any agricultural process based on the requirement. The agricultural tool (120) may comprise a plough, a disc plough, a reversible manual plough or any other type of agricultural tool. In an embodiment of the present disclosure, the agricultural tool (120) may also have plurality of disc blades without limiting the scope of the disclosure.
Referring now to Figure. 4 along with Figures. 1 and 2, the modular vehicle (100) may include a power take-off unit (109). The power take-off unit (109) may be configured to transmit power from the two-wheeler (101) of the modular vehicle (100) to the agricultural implement (102) in the second operational configuration for driving the agricultural implement (102) to perform agricultural activities. As seen in Figures. 2 and 4, the power

take-off unit (109) may include a frictional driven member (112) that may be supported by the frame structure (103) of the agricultural implement (102). The frictional driven member (112) may be concentrically disposable on a shaft (111) which may be fixed to the frame structure (103) of the agricultural implement such that, the frictional driven member (112) is rotatable relative to the frame structure (103) of the agricultural implement (102). Rotation of the frictional driven member (112) rotates that may be suitably transmitted from the modular vehicle (100) to the agricultural implement (102). In an embodiment, the frictional driven member (112) is supported by at least one bearing [not shown] on each side by frame structure (103) of the agricultural implement (102) for rotating relative to the drive wheel (113) of the modular vehicle (100) and the agricultural implement (102). As best seen in Figure. 2, when the agricultural implement (102) is connected to the modular vehicle (100) in the second operating configuration for performing agricultural activities, the frictional driven member (112) is structured to frictionally engage the drive wheel (113) of the modular vehicle (100). The power take-off unit (109) further includes a gearbox (105), being supported by the frame structure (103) of the agricultural implement (102). The gearbox (105) is structured to couple the frictional driven member (112) and a differential (108) of the agricultural implement (102) for transmitting torque generated at the frictional driven member (112) for driving the agricultural implement (102).
Referring to Figures. 2, 3 and 4, the frictional driven member (112) may be defined with a profile to complement at least a portion of the drive wheel (113) of the modular vehicle (100) to generate torque for driving the agricultural implement (102). In the illustrative embodiment, the frictional driven member (112) is a roller, where an outer circumference of the roller is in frictional engagement with an outer surface of the drive wheel (113). The outer surface of the frictional driven member (112) may be defined with profiles including, but not limited to, knurled pattern, horizontal slats, and any other profile that aids in increasing frictional engagement between the frictional driven member (112) and the drive wheel (113) for suitably generating and transmitting torque to the agricultural implement (102). In the illustrative embodiment, the roller is defined with the knurled pattern along the length so that, operation of the drive wheel (113) imparts sufficient friction on the roller for generating and transmitting torque to the agricultural implement (102). Profiling of the

frictional driven member (112) may also include defining of curvature along length of said frictional driven member (112) [i.e., length extending across the frame structure (103) of agricultural implement (102) to which the frictional driven member (112) is attached]. Such curvature of the frictional driven member (112) may be configured to increase contact area with the drive wheel (113) of the modular vehicle (100). Such increase in contact area may increase frictional engagement between the frictional driven member (112) and the drive wheel (113) of the modular vehicle (100). With increase in frictional engagement at the frictional driven member (112), torque transmitted to the gearbox (105) of the agricultural implement (102) may be increased and may be performed seamlessly. Here, it should be noted that the profiling of the frictional driven member (112) may be supplementary in nature, i.e., the frictional driven member (112) may be defined with at least one profile including knurled profile along the outer surface, curvature along the length, and a combination thereof, without departing from working principle of the frictional driven member (112).
In an embodiment, the frictional driven member (112) may be configured to engage at peripheral portion of the drive wheel (113) of the modular vehicle (100), to generate and transmit torque to the gearbox (105) of the agricultural implement (102). Such peripheral engagement between the frictional driven member (112) and the drive wheel (113) may minimize wear of tires on the drive wheel (113), rendering generation and transmission of torque to be unaffected even during prolonged operation of the modular vehicle (100) in the second operational configuration. In one embodiment, the drive wheel (113) of the modular vehicle (100) may include pneumatic tires or airless tires [i.e., non-pneumatic tires], for transmission of torque to the frictional drive member. Also, the drive member of the modular vehicle (100) may be configured to complement such operation of the frictional drive member. For instance, the drive wheel (113) may be defined with frictional pattern including, but not limited to, ribs, buttons, and the like, along the other surface for increasing frictional engagement with the frictional drive member, while also improving grip therebetween.
The gearbox (105) of the power take-off unit (109) may be configured to receive torque transmitted by the frictional driven member (112) and selectively step-up or step down

such torque for operating the agricultural implement (102). The gearbox (105) may be meshed with the differential (108) of the agricultural implement (102), where torque from the frictional driven member (112) may be suitably conveyed for operation and/or driving of the agricultural implement (102).
In an illustrated embodiment, structure of the frictional driven member (112) is cylindrical. However, the same cannot be construed as a limitation. In some embodiments the frictional driven member (112) may be defined with curvatures such as, convex outer surface, concave outer surface and a combination thereof, such that the frictional driven member (112) may engage with the drive wheel (113) of the modular vehicle (100).
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 (113) 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 engaging the frictional driven member (112) with the drive wheel (113) of the modular vehicle (100). During operation, corresponding to rotation of the drive wheel (113), the frictional driven member (112) may also rotate as a result of which the gearbox (105) and in-turn differential (108) of the agricultural implement (102) may be operated for driving the agricultural implement (102). Further, the frame structure (103) of the agricultural implement (102) may be defined with an elongated slot (115) in the plurality of extensions such that, position and/or orientation of the frictional driven member (112) may be linearly adjusted relative to the drive wheel (113) for maintaining frictional engagement to generate and transmit

torque and/or power even due to wear off of a portion of the drive wheel (113) and/or the frictional driven member (112). For example, in case of wear of the drive wheel (113), the frictional driven member (112) may be lifted towards the drive wheel (113) by positioning relative up the elongated slot (115) of the frame. Such lifting of the frictional driven member (112) may maintain constant frictional engagement with the drive wheel (113) for transmitting power from the drive wheel (113) to the frictional driven member (112) for generating and transmitting torque to the agricultural implement.
In an embodiment, to operate the vehicle back to the first operational configuration, the agricultural implement (102) may be disengaged from the body structure (110). Upon disengaging the agricultural implement (102), the driving wheel 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.
