Description
Technical Field
The present subject matter relates generally to a two-wheeled vehicle. More particularly, but not exclusively, the present subject matter relates to a frame assembly for a two-wheeled vehicle.
Background
Typically, a frame (also referred to as a chassis) is the primary support structure of the vehicle to which are attached all other parts of the vehicle, such as wheels, motors, one or more power units, and other related components. The frame serves as a skeleton capable of withstanding the load and inertia of the components or parts attached thereto. As technology evolves, new features are introduced, which in turn lead to an increase in the number of parts housed in the vehicle. For example, with the introduction of electric and hybrid vehicles, packaging requirements for batteries that can be used as a power source for vehicle traction are a significant challenge, particularly in two-wheeled vehicles where space is limited. In addition, other related components (e.g., motor, controller, etc.) require additional mounting parts for traction. Packaging the above components with additional new parts makes the vehicle layout cumbersome and complex, affecting ease of access for maintenance and ease of assembly.
Disclosure of Invention
In an electric or hybrid vehicle, to facilitate easy access while packaging a battery and related components as a power source, the overall width of the vehicle frame is increased to provide a working space between the components, but such a layout results in an undesirably heavy chassis. Typically, in electric and hybrid vehicles, the base frame is modified to accommodate all of the components of the vehicle, which increases the stresses on the frame. To cope with this additional stress, it is necessary to increase the frame strength and stiffness, which requires a heavier frame assembly.
In addition, it is not desirable to use a single frame to mount all of the components. In general, vehicle parts (such as motors, transmission assemblies, etc.) directly involved in vehicle traction generate a large amount of vibrations and this creates stresses on parts of the frame. In this case, if a portion of the frame is damaged, the entire frame needs to be replaced, which increases the cost of the vehicle from the standpoint of manufacturing and customers.
Accordingly, there is a need for a frame assembly for hybrid and electric vehicles that meets the above and other related needs while overcoming all of the problems in the art.
It is an object of the present subject matter to provide an improved layout of a frame assembly having a compact package, high frame strength and rigidity to handle additional stresses, facilitating efficient assembly, access and repair of components on a vehicle frame. The subject matter is described using an exemplary electric two-wheeled vehicle, while the claimed subject matter is applicable to two-wheeled electric vehicles and hybrid vehicles, with the required modifications made without departing from the scope of the invention.

The swing arm assembly 114 is connected at one end to the rear wheel assembly 112 and is also connected to a frame in the front portion 102 (a) of the vehicle 100.
Fig. 2 (a) exemplarily shows a side view of the front and rear of the frame assembly 101 having components of the two-wheeled electric vehicle 100. Fig. 2 (b) schematically illustrates an exploded perspective view of the components mounted on the frame assembly 101. The frame of the two-wheeled electric vehicle 100 is designed to house all electrical components and parts in a mass distribution concentrated manner, resulting in a center of gravity being disposed substantially near the center plane of the vehicle 100, thereby enhancing the balance and dynamic performance of the vehicle 100. When packaging all parts, it is kept in mind that the parts and components should be easy to assemble and easy to access during repair or maintenance. The frame assembly 101 houses an electric power unit 108 in the front of the vehicle 100. The electric power unit 108 is disposed in the vehicle width direction from the top of the vehicle 100, and is fixedly mounted to the frame assembly 101. The outer wall of the electric power unit 108 has a configuration of vents 116, the vents 116 being cutouts provided in the outer wall of the electric power unit 108 so that air flow from one or more of the cooling medium and cooling system (not shown) comprised of the atmosphere passes through the electric power unit 108 and components efficiently. The electric power unit 108 is integrated with a battery (not shown), a battery controller (not shown), a charging unit 109, and a charging port 115, assembled together as a subassembly, and then the electric power unit 108 is mounted to the frame assembly 101.
A controller unit 117 for controlling the main aspects of the vehicle 100 is assembled and mounted behind the electric power unit 108. The electric traction unit 110 is positioned at the bottom of the frame, below the electric power unit 108, such that the electric traction unit does not interfere with the electric power unit 108 during assembly or maintenance. The electric traction unit 110 is also mounted to the front as a subassembly in the vehicle width direction. The electric traction unit 110 is positioned in the lower part of the front part such that the transmission system (not shown) is directly connected with the electric traction unit without any obstruction. This ensures minimal transmission losses and thus facilitates efficient operation of the electric traction unit 110. According to another embodiment, a cooling unit 118 is provided at the front side of the electric traction unit 110 to cool the traction unit 110.
Fig. 3 (a) schematically illustrates an isometric view of the frame assembly 101. Fig. 3 (b) schematically illustrates a side view of the frame assembly. The frame assembly 101 of the two-wheeled vehicle 100 includes a front portion 102 (a) and a rear portion 102 (b). The front portion 102 (a) of the frame assembly 101 has a front upper structure 119 and a front lower structure 120. The front upper structure 119 is provided at an upper portion of the front portion 102 (a), and the front lower structure 120 is provided at a lower portion of the front portion 102 (a) of the frame. The rear structure 121 is provided in the rear portion 102 (b) of the frame. The front portion 102 (a) and the rear portion 102 (b) are configured to be detachably attached to form a frame of the vehicle 100. The detachable feature is disposed in an area generally beneath the rider seat and behind the electric power unit 108 of the vehicle 100. This enables a stable and stable frame construction to mount the power transmission unit including the electric power unit 108 and the electric traction unit 110. According to alternative embodiments, the rear of the frame assembly 101 is configured to be modular such that different rear structures may be configured to enable different vehicle designs (e.g., commute, sport, off-road, etc.) and rider-only configurations with a utility storage unit installed instead of the rear portion 102 (b) of the frame assembly 101. The front upper structure 119 houses an electric power unit (not shown in the figures), and the front lower structure 120 houses an electric traction unit (not shown). The front lower structure 120 is disposed below the front upper structure 119 via a mount (not shown). The rear portion 102 (b) is disposed rearward of the front portion 102 (a) of the vehicle 100. The electric traction unit 110 is positioned on the underside of the frame assembly 101 to ensure that it does not interfere with the electric power unit. Furthermore, the installation location of the electric traction unit 110 is easily accessible during assembly and maintenance. The location and mounting configuration of electric power unit 108 and electric traction unit 110 achieve an effective weight distribution. This configuration balances the mass distribution and thereby places the center of gravity closer to the center plane of the vehicle 100, thereby improving the stability of the vehicle and the overall vehicle ride and handling performance. In the present embodiment, the frame of the vehicle 100 is a tubular structure. The diameter of the frame tube is not changed and therefore the frame assembly 101 is not attached with any material. According to the invention, the cross-section of all the major components of the frame is substantially similar to that of a typical conventional two-wheeled vehicle consisting of conventional IC engine units. The cage structure of the front upper structure 119 is coupled with the cage structure of the front lower structure 120, and the tubular frame used in the frame assembly 101 of the vehicle 100 to enclose the parts of the vehicle 100 increases rigidity and provides strength to retain the components.
Fig. 4 schematically illustrates an exploded view of the frame assembly 101. In this embodiment, the front upper structure 119, the front lower structure 120, and the rear structure 121 of the frame assembly 101 are detachably attached. This allows individual access to the components without requiring individual removal of each part. Also, if a portion of the frame of the vehicle 100 is damaged, only that portion of the frame is replaced, and the entire frame of the vehicle 100 need not be replaced. This is a cost effective way to reduce the customer's burden when only a portion of the vehicle frame is damaged. Fig. 5 schematically illustrates an isometric view of the front upper structure 119 of the front portion 102 (a) of the frame assembly 101. The front upper structure 119 of the front portion 102 (a) of the vehicle 100 includes a head pipe 122, a front support member 123 extending obliquely downward from the head pipe 122, and a horizontal structure 124 extending rearward from the bottom of the front support member 123. The horizontal structure 124 includes a first cross member 125, a second longitudinal member 126, and a third longitudinal member 127 connected to form a support structure that is open at one end. The first cross member 125 extends in the vehicle width direction, and the second and third longitudinal members 126 and 127 extend rearward from both ends of the first cross member 125 in the vehicle length direction. In this embodiment, the second longitudinal member 126 and the third longitudinal member 127 are connected by one or more bottom support bridges 128. The horizontal structure 124 and the bottom support bridge 128 support an electric power unit (not shown) within the frame assembly 101.
The front upper structure 119 of the front portion 102 (a) of the vehicle 100 further includes a roof structure 129, the roof structure 129 including a first roof member 130 and a second roof member 131 extending obliquely rearward from the head pipe 122. The first and second top members 130, 131 extend rearwardly to form a progressively increasing space and then extend first rearwardly and then downwardly parallel to each other, the progressively increasing space forming a generally "V" shaped region between the two members (130, 131). The first top member 130 is connected to the second longitudinal member 126 of the horizontal structure 124 by a first side blocking member 132. The second top member 131 is connected to the third longitudinal member 127 of the horizontal structure 124 by a second side barrier member 133. A top blocking structure 134 formed in a generally C-shape connects the first top member 130 and the second top member 131 in at least one location. The top structure 129, head tube 122, front support member 123, and horizontal structure 124 define a housing for an electric power unit (not shown), and the first side blocking member 132, second side blocking member 133, and top blocking structure 134 are configured to lock the electric power unit (not shown) in the frame assembly 101. A rear locking member 135 is provided to mount a controller unit (not shown) on the underside of the top structure 129, the rear locking member 135 connecting the first and second top members 130, 131 and being disposed behind an electric power unit (not shown). Thus, the front upper structure 119 forms a closed cage-like barrier to fixedly and safely locate and install the electric power unit 108 therein and the controller unit 117 on the side outside the cage.

The front lower structure 120 of the front portion 102 (a) of the frame assembly 101 is detachably attached to the front upper structure 119 of the front portion 102 (a). In this embodiment, the front lower structure 120 has a pair of arc-shaped members 136 that first extend in a downward direction from the horizontal structure 124 and then extend rearward parallel to the ground. A rear closing member 137 is provided on the ends of the pair of arc members 136 and extends in an upward direction to close an electric traction unit (not shown) from the rear side, thus fixing the traction unit (not shown) via a plurality of fasteners 138. The pair of arc members 136 are connected at front ends to front mounting brackets 139 provided on the underside of the horizontal structure 124, and the pair of arc members 136 are connected at rear ends to rear mounting brackets 140, wherein the rear mounting brackets 140 are provided on the lower ends of the first and second top members 130, 131. A front mounting bracket 139 attached to the bottom of the horizontal structure 124 is configured to support an electric traction unit (not shown) from the front. A rear mounting bracket 140 attached to rear end portions of the first and second top members 130 and 131 supports a rear end of an electric traction unit (not shown). The front support members 142 are disposed inside the front sides of the pairs of arc members 136 such that an electric traction unit (not shown) securely rests on the support members 142 and does not move during operation. The underside of the rear mounting bracket 140 also supports a swing arm assembly (not shown) on its rear side. An electric traction unit (not shown) is first deployed within the front lower structure 120 and then the entire unit is assembled with the front upper structure 119 using mounting points at the front upper structure 119 of the frame assembly 101.
