The present invention relates to swing arm for a vehicle and vehicles, more particularly, to vehicles which utilizes swing arm to support rear wheel of the vehicle.
5 BACKGROUND
[002] 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. [003] Swing arms are typically used on vehicles, for example, two-wheeled vehicle, where a single wheel, for example, rear wheel of the vehicle, is fixed to a vehicle frame
10 at one end thereof. Swing arms are intended to provide a strong structural connection of the wheel to the vehicle frame while withstanding significant forces imposed by movement of the vehicle and loads carried by the vehicle, thereby facilitating enhanced drivability to the vehicles. Also, swing arms are required to offer high stiffness. [004] In the case of a two-wheeled vehicle, a swing arm may be mounted at a rear side
15 of the vehicle to pivotally fix and suspend a rear wheel of the vehicle. Often, the wheel is driven by a system of gears and sprockets connected with a driving belt or chain. In such an application, the swing arm is typically provided at one side of the rear wheel's rotational axis in order to pivotally fix the wheel to the vehicle frame. However, such configuration of the vehicle with the swing arm mounted at only one side of the rear
20 wheel, desired stiffness of the swing arm is not achieved.
[005] Accordingly, there remains a need for an improved swing arm for a vehicle that overcomes at least one of the problems identified above, and that provides better aesthetics with regard to the vehicle, offers high stiffness and high drivability to the vehicle.
