Electric motorcycle drivetrain assembly

Abstract

The invention relates to the drive unit of an electric motorcycle, including: (A) integrating an electric drive mechanism including a motor, multi-stage gearbox and output shaft in the wheel; (B) arranging a heat dissipation structure on the electric motorcycle fork to enhance the heat dissipation efficiency of the electric drive mechanism; (C) designing wheel rim spokes consisting of many fan-shaped spokes, to increase the heat dissipation efficiency of the electric drive mechanism and brake disc when the electric motorcycle is running; (D) Install a fan inside the motor housing to enhance the motor's heat dissipation efficiency during electric motorcycle operation; and (E) Use a brushless DC (BLDC) motor as the motor for the electric drive mechanism, and connect a suitable cooling device to the BLDC motor to increase the peak power of the electric drive mechanism and the torque of the BIOC motor.
