Description

[0001] “VEHICLE, AND BODY FRAME OF VEHICLE”

[0002] TECHNICAL FIELD

[0003]

[0001] The present application relates to the field of two- wheeled vehicles. Particularly, the present application relates to a coupling unit configured to couple components of the two-wheeled vehicle. Further, the present application, in general, relates to the field of vehicles. Particularly, but not exclusively, the present application relates to a body frame of a vehicle. The present application discloses a pivot frame for mounting a power transmitting unit to the body frame of the vehicle.

[0004] BACKGROUND

[0005]

[0002] The information in this section merely provides background information related to the present disclosure and may not constitute prior art(s) for the present disclosure.

[0006]

[0003] In a two-wheeled vehicle, a frame or chassis is the base on which other components of the motorcycle including handlebars, fuel tank, seat, swing arm, shock absorber(s), and wheels are mounted. The frame is a core structure which supports a motor and provides a location for the steering and rear suspension. The frame also supports the vehicle’s components to deal with static and dynamic loads without undue deflection or distortion.

[0007]

[0004] A generally known two-wheeled vehicle (hereinafter referred to as “vehicle”) comprises a vehicle frame having a mainframe tube extending rearwardly in a longitudinal direction of the vehicle. The vehicle comprises a drive motor that is coupled to the vehicle frame and adapted to control one or more operations of the vehicle. The vehicle furthermore comprises a battery unit that is coupled to the vehicle frame and is disposed ahead of the drive motor along a longitudinal direction of the vehicle.

[0008]

[0005] During operation of the vehicle, when the vehicle travels over an uneven terrain or a bumpy surface, an initial distance of separation between the drive motor and the battery unit increases, due to which the weight distribution of the components on the vehicle frame changes, leading to stresses and fatigue being introduced at the coupling points, majorly the mainframe tube, of the vehicle frame. Excessive stresses and fatigue of the vehicle frame often leads to failure of the vehicle frame.

[0009]

[0006] Conventional known solutions disclose an electric vehicle comprising a body frame structure. Said body frame structure comprises a head pipe that supports a front wheel, a front frame that extends from the head pipe to the rear of the vehicle, and a seat. Further, said body frame structure comprises a battery case that is formed to accommodate a battery / battery pack, is located behind the vehicle from the head pipe and is connected to the front frame. Furthermore, said body frame structure comprises a motor case for housing a motor and is connected to a rear frame of the body frame structure. However, when the said electric vehicle travels over an uneven terrain or a bumpy surface, for the reason that both the battery case and the motor case form part of the body frame structure, the weight distribution of the components on the body frame structure changes, leading to stresses and fatigue being introduced at the coupling points of the body frame structure. Excessive stresses and fatigue of the body frame structure leads to failure of the body frame structure. Also, the conventional known solutions result in heavy or bulky body frame structures, thereby imparting various structural limitations in the body frame structure of the vehicle, for example, an impact on a range / battery life of the vehicle.

[0010]

[0007] Conventionally, the drive motor is mounted on the frame structure and is assembled on a pivot frame where a swing arm of the vehicle is also connected. For electric vehicles, the motor is packaged at center of swing arm pivot. Considering such packaging requirement, the frame structure requires a swing arm pivot which may mount the swing arm as well as the drive motor. Further, in order to mount the drive motor on the frame, a very strong structure is required as all the lateral loads are directed towards the drive motor. Thus, conventionally, a strong forged structure is mounted which connects the frame of the vehicle with the drive motor.

[0011]

[0008] However, there are certain limitations of the forged structure such as it is difficult to manufacture or process such a bulky structure keeping into consideration the mounting constraint of the motor on the frame. Also, the weight of the forged structure is also very high due to which it affects the range of the vehicle and the in the electric vehicle the weight plays a crucial role. Thus, the increase in the weight of the structure makes a significant concern for electric vehicle.

[0012]

[0009] Accordingly, there remains a need in the domain for a vehicle that addresses at least the above-mentioned technical problems.
