[002] A two wheeler light category 1 motorcycle (2W L-1 category) represents a class of motorcycle with maximum speed not exceeding 45 km/h and engine capacity not exceeding 50cc which is fitted with thermic engine or motor power not exceeding 0.5 kilo watt when fitted with electric motor.

[003] Conventionally, different types of motorcycles utilize different types of chassis assembly. A chassis assembly of motorcycles, in general, comprises a structure of either a passenger vehicle (see, for example, JP6161023B2) or a cargo vehicle (see, for example, KR200240268Y1). Passenger motorcycle generally consists of two wheels and engine, allowing a person to travel in narrow lanes and cities. On the other hand, cargo motorcycle, comprises of an open or enclosed box designed to transport heavy loads in wider roads and field areas. In the prior arts that have been disclosed, however, no attempts are made to commonize and integrate both, passenger and cargo motorcycles.

[004] Conventionally, in motorcycles, the center of gravity generally comprises a frame which is not specialized (see, for example, US4903790) and have basic functions. No attempts are made to ensure that the chassis ensures that the vehicle is aligned towards center of gravity to maintain adequate balance.

[005] Therefore, there is a demand for multi-tasking first of a kind two wheeler light category 1 vehicle, that can be used for multiple works, carry heavy loads and involves less vehicle development time, commonization of parts and minimal inventory for plant.

OBJECTIVES OF THE INVENTION
[006] The primary objective of the present invention is to provide advanced two-wheeler chassis assembly.

[007] Another objective of the present invention is to provide maximum efficiency and smooth functioning of the vehicle.

[008] Another objective of the present invention is to ensure execution of multiple works, carrying heavy load, being economical and not requiring separate investments and component development.

[009] Another objective of the present invention is to provide location of battery near motor and controller.

[0010] Yet another objective of the present invention is to incorporate louvers for cooling of controller.

[0011] Yet another objective of the present invention is to provide advanced electrical layout to get minimum voltage drop.

[0012] Yet another objective of the present invention is to provide better ergonomics and aesthetic look to the vehicle.

[0013] Other objectives and advantages of the present invention will become apparent from the following description taken in connection with the accompanying drawings, wherein, by way of illustration and example, the aspects of the present invention are disclosed.
SUMMARY OF THE INVENTION
[0014] The present invention relates to a two wheeler light category 1 vehicle chassis assembly comprising the motor (1), the gear box (2), the controller (3), the chain drive (4), the footrest (5) and the battery (6), wherein all the components are arranged at the center of gravity of the vehicle, thereby providing smooth functioning and maximum efficiency with less wear and tear, hence enhances overall performance of the vehicle. Further, louvers are placed near to the controller (3) and the battery (6) in order to provide ventilation and to maintain the optimized temperature by efficiently dissipating the heat. The advanced chassis assembly creates more space for rider and provides multitasking features, such that the rider gets ample leg space while riding the vehicle alone along with cargo loads at the backside, ensuring execution of multiple works, being economical and not requiring separate investment and component development.

In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

[0025] Features that are described and/or illustrated with respect to one embodiment may be used in the same way or in a similar way in one or more other embodiments and/or in combination with or instead of the features of the other embodiments.

[0026] The terms and words used in the following description are not limited to the bibliographical meanings, but, are merely used to enable a clear and consistent understanding of the invention. Accordingly, it should be apparent to those skilled in the art that the following description of exemplary embodiments of the present invention are provided for illustrative purpose only and not for the purpose of limiting the invention.

[0027] It is to be understood that the singular forms “a”, “an” and “the” include plural referents unless the context clearly dictates otherwise.

[0028] It should be emphasized that the term “comprises/comprising” when used in this specification is taken to specify the presence of stated features, steps or components but does not preclude the presence or addition of one or more other features, steps, components or groups thereof.

[0029] Accordingly, the present invention relates to an automobile field. Particularly, the present invention relates to an advanced two-wheeler vehicle chassis assembly providing compact arrangements of components at the center of gravity thereby reducing the mechanical loss and enhancing overall efficiency of the vehicle.

[0030] In the present embodiment, the two wheeler chassis assembly comprising a motor (1), a gear box (2), a controller (3), a chain drive (4), a footrest (5), and a battery (6). The arrangement of the chassis assembly ensures execution of multiple works, carrying heavy load, being economical and not requiring separate investments and component development.

[0031] In the present embodiment, as shown in Figure 1 and Figure 2, front view and side view of the two wheeler vehicle respectively illustrates the chassis assembly which is inclined towards the center of gravity. The chassis assembly is a twin tube construction bound with street metal structure. The chassis assembly comprises of the motor (1). In an exemplary embodiment, the motor may be, but not limited to, a DC series motor, a brushless DC motor, a permanent magnet synchronous motor.

[0032] In the present embodiment, Figure 3, Figure 4 and Figure 5 illustrates the motor (1), the gear box (2), controller (3), chain drive (4) and battery (6). The gear box (2) is installed in the proximity of the motor (1). The gearbox (2) is a power transfer system which distribute the motor (1) power to other components to produce movement.

[0033] The controller (3) is installed in the proximity of the gear box (2). The controller (3) converts the battery’s (6) direct current into alternating current thereby regulating the operation of the motor (1).
