Description

Technical Field

[0001] The present subject matter relates to a two-wheeled or three-wheeled motor vehicle and more particularly, but not exclusively, to a vehicle layout for a two-wheeled vehicle packaging one or more electric motors in the vehicle. Background Art

[0002] In conventional vehicles, one or more electric motors are packaged in the vehicle. Electrically driven autonomous vehicles include drive motors that require minimal space and are capable of driving the vehicle wheels through simple mechanical interconnections. Various arrangements of drive motors include hub mounted motors and shaft rotating motors. A hub mounted motor is one such arrangement where the vehicle drive motor is mounted directly within each vehicle wheel. There are arrangements that include motors that are mounted to a portion of the chassis. Conventionally, one or more motors are disposed on the right or left side of the vehicle.

[0003] Motors mounted directly to the wheels of a vehicle present various problems. In particular, wheel hub motors are mounted to the rear wheels in a vehicle. There are various limitations to mounting a wheel hub motor to the rear wheels of a vehicle. Limitations regarding motor capacity are universal. Wheel hub motors are always smaller capacity motors due to the configuration that can be supported on the rear wheels. Higher capacity wheel hub motors will be larger size motors. Larger wheel hub motors cannot actually be supported on the rear wheels unless the wheel size is increased (which is undesirable). Therefore, higher capacity wheel hub motors cannot be installed in vehicles because higher capacity increases the weight of the rear wheels. Typically, vehicles incorporating wheel hub motors have smaller motor capacities, and smaller capacities provide less torque and power. In addition, wheel hub motors that are part of the rear wheels include limitations on natural cooling. Since the motor is located inside the wheel, the wheel hub motor typically has the problem of insufficient cooling. The heat released due to the normal function of the motor is restricted from being dissipated to the outside atmosphere. The heat trapped inside the motor and wheel may cause the metal parts of the wheel to deform. In addition, all shocks and loads transmitted to the wheel by the road are also transmitted to the wheel hub motor. The mounting of the wheel hub motor to the rear wheel is prone to shifting or loosening after a period of time. A displaced hub motor may cause serious irreversible danger. In addition, due to the weight of the hub motor, certain other problems such as rim deformation or bending are observed. The phenomenon of rim deformation or bending may cause leakage of water inside the hub motor and cause a short circuit in the motor. Placing the drive motor in any other position of the vehicle will adversely affect the compactness of the vehicle and its layout, and is therefore not ideal. Therefore, there is a need for an improved layout configuration for hub motor installation for a compact saddle-ride type vehicle, which overcomes all of the above-mentioned problems and other problems of the prior art. Summary of the invention

[0004] To overcome the above problems, the present subject matter provides a new layout configuration for positioning the motor and a simple mechanism for mounting the shaft motor in a vehicle. The shaft motor is mounted in the vehicle above a mounting structure, which is in turn configured to be mounted above a rocker arm structure of the vehicle.
