Description:TECHNICAL FIELD
[0001] The present disclosure relates to an adjustment mechanism for a vehicle. In particular, the present disclosure provides a rear axle adjustment mechanism for a swing arm of a vehicle.

BACKGROUND
[0002] Generally, in a vehicle, rear axle adjustment mechanisms may be attached to both sides of a swing arm. Conventionally, the swing arm may be an aluminium casted swing arm, which may be highly expensive. The rear axle adjustment mechanism may be used along with a rear axle to orient/align a rear wheel and a transmission with the vehicle. The rear axle may act as a power transmitting member to transmit power to driving wheels of the vehicle.
[0003] Conventionally, as illustrated in FIG. 1B, an outer portion of a swing arm (102) may include a slot. The slot may be provided on a left side and a right side of the swing arm (102). Axle adjusters (108) may be provided, on both sides, on the outer portion of the swing arm (102). The swing arm (102) may include a tapping arranged on a surface perpendicular to a surface on which the axle adjuster (108) is provided. A bolt (106) may be inserted into the tapping with a freely moving nut (104) on the left side and the right side of the swing arm (102). A rear wheel assembly may be inserted into the swing arm (102) and aligned with the axle adjusters (108) on both sides of the swing arm (102) along with the rear axle. The axle adjusters (108) on both sides of the swing arm (102) may be pushed rearward against a swing arm surface by torquing the bolts (106) on both sides. The nuts (104) may be tightened against the swing arm surface, thereby restricting loosening of a joint between the rear wheel assembly and the swing arm (102), keeping the rear wheel assembly in a desired orientation, and maintaining a tension in a transmission secondary belt. The distance between the surface on which the nut (104) is resting and a frontward surface of the axle adjuster (108) may be maintained with a delta on the left side and the right side for wheel and transmission alignment.
[0004] However, achieving tighter tolerances on a width of the conventional rear axle adjustment mechanisms is difficult, thereby causing a higher gap between the axle adjusters (108) and an inner width of a main tube of the swing arm (102). This may lead to assembly stress with higher strain % in the main tube of the swing arm (102).
[0005] There is, therefore, a need for an improved rear axle adjustment mechanism to control a gap between the axle adjuster and the inner width of the swing arm main tube by overcoming the deficiencies in the prior art(s).

OBJECTS OF THE PRESENT DISCLOSURE
[0006] A general object of the present disclosure is to provide a rear axle adjustment mechanism with an axle adjuster assembly in a cost-effective manner.
[0007] An object of the present disclosure is to provide a rear axle adjustment mechanism with an extended bush protruded outside a first plate and a second plate of a sheet member.
[0008] An object of the present disclosure is to provide an extended bush with a protruded portion that interfaces an inner surface of a swing arm main tube so that a gap is formed between each of a first plate and a second plate and an inner surface of the swing arm main tube.
[0009] An object of the present disclosure is to provide an extended bush to control a gap between an axle adjuster assembly and an inner width of a swing arm main tube.
[0010] Another object of the present disclosure is to provide an axle adjuster assembly that reduces an assembly stress and a strain percentage in a swing arm main tube caused due to application of torque on a fastener connecting the axle adjuster assembly and the swing arm main tube.

For example, reference numerals starting with digit “1” are shown at least in Figure 1. Similarly, reference numerals starting with digit “2” are shown at least in Figure 2.
[0037] An Electric Vehicle (EV) 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. Furthermore, the electric vehicle 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 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).
[0038] In construction, as shown in FIG. 1A, an 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), an 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 (12) via the BMS.
[0039] 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.
[0040] 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).
[0041] 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 (10). Generally, the transmission systems (18) used in EVs (10) 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 (10) 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.
[0042] 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.

[0060] In some embodiments, a first fastener (314) may be fastened to a rear side of the adjuster plate (312) to pull the adjustment mechanism (300) rearward against the adjuster plate (312). In some embodiments, the fastening of the first fastener (314) may be adjusted to control a frontward movement and a rearward movement of the adjustment mechanism (300).
[0061] In some embodiments, a second fastener (316) may be fastened in proximity to the first fastener (314) to prevent slacking of the first fastener (314).
[0062] FIG. 4 illustrates an exemplary exploded view of an axle adjuster assembly (310), according to embodiments of the present disclosure.
[0063] With reference to FIG. 4, the axle adjuster assembly (310) may include a sheet member (302), an extended bush (306), and a stud (308).
[0064] In some embodiments, the sheet member (302) may include a plurality of plates, for example, but not limited to, a first plate (302a), a second plate (302b), and a rear plate (302c). In some embodiments, the first plate (302a) may be bendably connected to the second plate (302b) via the rear plate (302c). In some embodiments, each of the first plate (302a) and the second plate (302b) may include an opening (304).
[0065] In some embodiments, the extended bush (306) may be welded to an inner side of the sheet member (302) along an edge of the opening (304). In some embodiments, the extended bush (306) may be protruded outside the first plate (302a) and the second plate (302b). In some embodiments, a protruded portion (306a) of the extended bush (306) may interface an inner surface of the swing arm main tube (210) so that a gap may be formed between each of the first plate (302a) and the second plate (302b) and the inner surface of the swing arm main tube (210).
