Description:FIELD OF THE INVENTION

[0001] The present disclosure relates to vehicles, and more particularly, the present disclosure relates to a swing arm structure used in vehicles, such as two-wheelers.
BACKGROUND

[0002] A swing arm is a mechanical component used typically in a two-wheeler vehicle for attaching the rear wheel to the body. It is the main component of the two-wheeler suspension, which holds a driveshaft therein. The swing arm provides the mountings for powertrain (motor) and drivetrain (gearbox & driveshafts). Generally, the design of the swing arm can be either single sided or dual-sided which impacts the durability, vehicle handling, and performance of the vehicle.
[0003] Both the single sided and dual-sided swing arms have their own limitations and advantages. For example, single sided swing arms are often more complex in design in comparison to dual-sided swing arms. This is because single sided swing arms may impact weight distribution of the two-wheeler vehicle. The asymmetrical design may affect the handling characteristics and therefore some riders may prefer the more balanced weight distribution offered by the dual-sided swing arm. The increased design complexities also mean that routine maintenance tasks, such as rear wheel removal are more complicated due to the requirement of special tools for tire changes.
[0004] On the other hand, the dual-sided swing arms typically have higher unsprung weight due to the presence of additional components. The increased unsprung weight affects the handling characteristics, such as acceleration, cornering ability, and braking of the two-wheeled vehicle. The increased number of components also adds to space requirements. As such, riders may prefer the single sided swing arm that is more visually appealing, has a smaller number of components, reduced overall weight, and reduced space requirements.
[0005] Since the dual-sided and single sided swing arms have advantages and disadvantages, the rider may prefer to switch from a single sided swing arm configuration to a dual-sided swing arm configuration and vice versa based on his/her preference. A commonly observed problem when switching from the single sided swing arm configuration to the dual-sided swing arm configuration or vice versa is the requirement of having different designs of the swing arm, the wheels, and the driveshafts for each configuration.
[0006] This is a disadvantage as the components of the vehicle are designed to suitably implement only one of the configurations and does not allow for the possibility of interchangeably installing the single sided swing arm configuration or the dual-sided swing arm configuration on the same vehicle as per the need of the rider. There are several major drawbacks associated with the designs that are suitable only for either of the configurations. Firstly, in case the same vehicle has two different variants, the swing arms must be designed differently for the two different variants, which increases the tooling and/or manufacturing costs and development time of different variants of the vehicle. Secondly, inventory management is far more challenging with two distinctive design structures going into production.
[0007] Therefore, in view of the above-mentioned problems, there is a need for a technical solution that overcomes the above mentioned problems and facilitates a modular swing arm structure that can switch from a dual-sided swing arm configuration to a single sided swing arm configuration and vice versa without changing the design of the wheels and the drivetrain components.

[0032] In an embodiment, a vehicle 10 may primarily work on the principle of driving the vehicle 10 with a power unit, for example, an engine, without departing from the scope of the present disclosure. In yet another embodiment, the vehicle 10 may primarily work on the principle of driving the vehicle 10 with the engine and an electric motor 16, without departing from the scope of the present disclosure.
[0033] In an embodiment, the vehicle 10 may be an Electric Vehicle (EV) 10 or a battery powered vehicle including, and not limited to two-wheelers such as scooters, mopeds, motorbikes/motorcycles; three-wheelers such as auto-rickshaws, four-wheelers such as cars and other Light Commercial Vehicles (LCVs) and Heavy Commercial Vehicles (HCVs) primarily work on the principle of driving an electric motor using the power from the batteries provided in the EV 10.
[0034] Furthermore, the electric vehicle 10 may have at least one wheel which is electrically powered to traverse such a vehicle. The term ‘wheel’ may be referred to any ground-engaging member which allows traversal of the electric vehicle 10 over a path. The types of EVs include Battery Electric Vehicle (BEV), Hybrid Electric Vehicle (HEV) and Range Extended Electric Vehicle. However, the subsequent paragraphs pertain to the different elements of a Battery Electric Vehicle (BEV).
[0035] Furthermore, the electric vehicle 10 may have at least one wheel that is electrically powered to traverse such a vehicle. The term ‘wheel’ may be referred to any ground-engaging member that allows traversal of the electric vehicle over a path. The types of EVs include a Battery Electric Vehicle (BEV), a Hybrid Electric Vehicle (HEV), and a Range Extended Electric Vehicle. However, the subsequent paragraphs pertain to the different elements of the Battery Electric Vehicle (BEV). In an embodiment, the vehicle 10 may be interchangeably referred to as the electric vehicle or EV, without departing from the scope of the present disclosure.
[0036] In construction, the EV (10) typically comprises a battery or battery pack (12) enclosed within a battery casing and includes a Battery Management System (BMS), an on-board charger (14), a Motor Controller Unit (MCU), the electric motor (16) and an electric transmission system (18). The primary function of the above-mentioned elements is detailed in the subsequent paragraphs: The battery of an EV (10) (also known as Electric Vehicle Battery (EVB) or traction battery) is re-chargeable in nature and is the primary source of energy required for the operation of the EV, wherein the battery (12) is typically charged using the electric current taken from the grid through a charging infrastructure (20). The battery may be charged using Alternating Current (AC) or Direct Current (DC), wherein in case of AC input, the on-board charger (14) converts the AC signal to DC signal after which the DC signal is transmitted to the battery via the BMS. However, in case of DC charging, the on-board charger (14) is bypassed, and the current is transmitted directly to the battery via the BMS.
[0037] The battery (12) is made up of a plurality of cells which are grouped into a plurality of modules in a manner in which the temperature difference between the cells does not exceed 5 degrees Celsius. The terms “battery”, “cell”, and “battery cell” may be used interchangeably and may refer to any of a variety of different rechargeable cell compositions and configurations including, but not limited to, lithium-ion (e.g., lithium iron phosphate, lithium cobalt oxide, other lithium metal oxides, etc.), lithium-ion polymer, nickel metal hydride, nickel cadmium, nickel hydrogen, nickel-zinc, silver zinc, or other battery type/configuration. The term “battery pack” as used herein may be referred to multiple individual batteries enclosed within a single structure or multi-piece structure. The individual batteries may be electrically interconnected to achieve a desired voltage and capacity for a desired application. The Battery Management System (BMS) is an electronic system whose primary function is to ensure that the battery (12) is operating safely and efficiently. The BMS continuously monitors different parameters of the battery such as temperature, voltage, current and so on, and communicates these parameters to the Electronic Control Unit (ECU) and the Motor Controller Unit (MCU) in the EV using a plurality of protocols including and not limited to Controller Area Network (CAN) bus protocol which facilitates the communication between the ECU/MCU and other peripheral elements of the EV (10) without the requirement of a host computer.
[0038] The MCU primarily controls/regulates the operation of the electric motor based on the signal transmitted from the vehicle battery, wherein the primary functions of the MCU include starting of the electric motor (16), stopping the electric motor (16), controlling the speed of the electric motor (16), enabling the vehicle to move in the reverse direction and protect the electric motor (16) from premature wear and tear. The primary function of the electric motor (16) is to convert electrical energy into mechanical energy, wherein the converted mechanical energy is subsequently transferred to the transmission system of the EV to facilitate movement of the EV. Additionally, the electric motor (16) also acts as a generator during regenerative braking (i.e., kinetic energy generated during vehicle braking/deceleration is converted into potential energy and stored in the battery of the EV). The types of motors generally employed in EVs include, but are not limited to DC series motor, Brushless DC motor (also known as BLDC motors), Permanent Magnet Synchronous Motor (PMSM), Three Phase AC Induction Motors and Switched Reluctance Motors (SRM).
[0039] The transmission system (18) of the EV (10) facilitates the transfer of the generated mechanical energy by the electric motor (16) to the wheels (22a, 22b) of the EV. Generally, the transmission systems (18) used in EVs include single speed transmission system and multi-speed (i.e., two-speed) transmission system, wherein the single speed transmission system comprises a single gear pair whereby the EV is maintained at a constant speed. However, the multi-speed/two-speed transmission system comprises a compound planetary gear system with a double pinion planetary gear set and a single pinion planetary gear set thereby resulting in two different gear ratios which facilitates higher torque and vehicle speed.
[0040] In one embodiment, all data pertaining to the EV (10) and/or charging infrastructure (20) are collected and processed using a remote server (known as cloud) (24), wherein the processed data is indicated to the rider/driver of the EV (10) through a display unit present in the dashboard (26) of the EV (10). In an embodiment, the display unit may be an interactive display unit. In another embodiment, the display unit may be a non-interactive display unit.
[0041] As used herein, the term “swing arm” broadly refers to the mechanical component used typically in a two-wheeler vehicle for attaching a wheel to the frame of the two-wheeled vehicle. The swing arm provides mounting surfaces adapted to mount a powertrain (motor), a drivetrain (gearbox and driveshafts), and suspension components (shock absorbers). A swing arm assembly 100, disclosed herein, is designed such that the swing arm assembly 100 may be interchangeably used in a single swing arm configuration or in a dual swing arm configuration as will be explained in the subsequent paragraphs. The present disclosure also discloses a saddle-type vehicle including a frame, the swing arm assembly 100 having a primary swing arm 101, a secondary swing arm 105, at least one wheel, and at least one spacer 106.
[0042] Figure 2A illustrates a perspective view of the swing arm assembly 100 configured in a single swing arm configuration, according to an embodiment of the present disclosure. Figure 2B illustrates a front planar view of the swing arm assembly 100 configured in the single swing arm configuration, according to an embodiment of the present disclosure. Figure 2C illustrates a top planar view of the swing arm assembly 100 configured in the single swing arm configuration, according to an embodiment of the present disclosure.
[0043] The swing arm assembly 100 for a saddle-type vehicle includes the primary swing arm 101 extending from a pivot element 102 adapted to be coupled to a frame of the saddle-type vehicle. The primary swing arm 101 is adapted to be coupled to a gearbox 103 of the saddle-type vehicle. The saddle type vehicle also includes a driveshaft 104 coupled to at least one wheel (not shown). The swing arm assembly 100, shown in Figures 2A-2C, is configured in a single swing arm configuration. This means a secondary swing arm 105, shown in Figures 2D-2F, is adapted to be de-coupled from the pivot element 102 and the driveshaft 104 to configure the swing arm assembly 100 in the single swing-arm configuration. The swing arm assembly 100 also includes at least one spacer 106 adapted to be concentrically coupled to the driveshaft 104.
[0044] Figure 2D illustrates a perspective view of the swing arm assembly 100 being configured in a dual swing arm configuration from the single swing arm configuration, according to an embodiment of the present disclosure. Figure 2E illustrates a front planar view of the swing arm assembly 100 configured in the dual swing arm configuration, according to an embodiment of the present disclosure. Figure 2F illustrates a top planar view of the swing arm assembly 100 configured in the dual swing arm configuration, according to an embodiment of the present disclosure. As illustrated in Figure 2D, the secondary swing arm 105 includes a first end 105a adapted to be removably coupled proximal to the pivot element 102. Moreover, the secondary swing arm 105 includes a second end 105b adapted to be removably coupled to the driveshaft 104.
[0045] In the dual swing-arm configuration, the secondary swing arm 105 is adapted to be coupled to the pivot element 102 and the driveshaft 104. The pivot element 102 includes a supporting bracket 107 having at least three welded nuts 107a adapted to removably couple the first end 105a of the secondary swing arm 105 via fasteners. In an embodiment, the wheel hub is coupled to the gearbox 103 prior to coupling of the secondary swing arm 105. Alternatively, to configure the swing arm assembly 100 back to the single swing-arm configuration, the secondary swing arm 105 is adapted to be de-coupled from the pivot element 102 and the driveshaft 104. The fasteners are removed from the three welded nuts 107a to decouple the secondary swing arm 105 from the swing arm assembly 100.
[0046] The at least one spacer 106 is adapted to be concentrically coupled to the driveshaft 104 such that in the dual swing-arm configuration, the spacer 106 is positioned between the wheel and the secondary swing arm 105. On the other hand, in the single swing-arm configuration, the spacer 106 is adapted to conceal a portion of the driveshaft 104 extending through the at least one wheel. In an embodiment, the spacer 106 is made of a metallic material and may be internally threaded such that the spacer 106 is torqued over the portion of the driveshaft 104 that is exposed. In an embodiment, the length of the spacer 106 may be adjustable. For example, the spacer 106 may have a telescopically extendible and/or retractable mechanism such that the length of the spacer 106 may be adjusted according to the length of the exposed portion of the driveshaft 104. In an embodiment, the spacer 106 used in the dual swing-arm configuration and the spacer 106 used in the single swing-arm configuration are distinct spacers. In yet another embodiment according to the disclosure, the length of the spacer 106 in the dual swing-arm configuration may be lesser than the length of the spacer 106 in the single swing-arm configuration. In an embodiment, the primary swing arm 101 includes a mounting surface (not shown) adapted to couple a first shock absorber (not shown). Similarly, in the dual swing-arm configuration, the secondary swing arm 105 includes a mounting surface (not shown) adapted to couple a second shock absorber (not shown).

[0047] Figure 3 illustrates a flow chart depicting a method 300 for configuring the swing arm assembly 100 in the dual swing-arm configuration, according to an embodiment of the present disclosure. Details of the swing arm assembly 100 that have already been explained in the detailed descriptions of Figures 2A-2F are not explained again in the subsequent paragraphs for the sake of brevity.

[0048] Therefore, referring to Figures 2A-3 and the components already disclosed in detail, the method 300, disclosed herein, for configuring the swing arm assembly 100 in the dual swing-arm configuration includes at step 301, providing the swing arm assembly 100 including the primary swing arm 101 and the pivot element 102 such that the primary swing arm 101 is adapted to be coupled to the frame and the gearbox 103 of the saddle-type vehicle having the driveshaft 104 coupled to the wheel.
[0049] At Step 303, the method 300 includes coupling the pivot element 102 of the swing arm assembly 100 to the frame of the saddle-type vehicle.
[0050] At Step 305, the method 300 includes mounting the wheel hub to the gearbox 103 of the saddle-type vehicle.
[0051] At Step 307, the method 300 includes fastening the first end 105a of the secondary swing arm 105 to the at least three welded nuts 107a of the supporting bracket 107 via the fasteners. It may be appreciated that the number of welded nuts may be increased or decreased based on design requirements.
[0052] At Step 309, the method 300 includes fastening the at least one spacer 106 over an exposed portion of the driveshaft 104.
[0053] At Step 311, the method 300 includes fastening the second end 105b of the secondary swing arm 105 to the driveshaft 104 via the axle nut 105c.
[0054] The swing arm assembly 100 disclosed herein provides several advantages over the existing swing arm assemblies. Since the swing arm assembly 100 is designed in such a manner, the swing arm assembly 100 may be used in the single swing-arm configuration and easily converted to or configured in the dual swing-arm configuration based on the preference of the rider or manufacturer. The ease of assembly and/or dismantling the secondary swing arm 105 from the swing arm assembly 100 ensures the vehicle may be easily converted to the dual swing-arm configuration. For riders who prefer the single swing-arm configuration, the secondary swing arm 105 may be easily decoupled.
[0055] From the manufacturer’s perspective, the swing arm assembly 100 disclosed herein, reduces the manufacturing and tooling costs. This is because for distinct variants of the vehicle, the same type of swing arm assembly 100 may be used with or without the secondary swing arm 105 based on the performance requirements or the weight of each variant. For example, a lighter variant of the vehicle may use the single swing-arm configuration and a heavier variant of the vehicle uses may use the dual swing-arm configuration. For both variants, the manufacturer need only make the swing arm assembly 100 without changing the design or type of mounting for the individual components. Advantageously, this reduces the manufacturing and tooling costs. Moreover, the universal design reduces the burden for inventory management and after sales service teams since the teams do not need to track different components for different variants of the vehicle.
[0056] In this application, unless specifically stated otherwise, the use of the singular includes the plural and the use of “or” means “and/or.” Furthermore, use of the terms “including” or “having” is not limiting. Any range described herein will be understood to include the endpoints and all values between the endpoints. Features of the disclosed embodiments may be combined, rearranged, omitted, etc., within the scope of the invention to produce additional embodiments. Furthermore, certain features may sometimes be used to advantage without a corresponding use of other features.
