Title:
ELECTRICALLY-DRIVEN POWER UNIT AND ELECTRIC MOTORCYCLE
Document Type and Number:
WIPO Patent Application WO/2017/096629
Kind Code:
A1
Abstract:
An electrically-driven power unit, comprising a motor (1), a clutch (2), a transmission (3), and a controller (4). The transmission (3) comprises a main shaft (31), a secondary shaft (32) used for outputting power to the outside, and a speed change gear set (33), wherein the speed change gear set (33) is connected between the main shaft (31) and the secondary shaft (32), and the speed change gear set (33) is connected with a gear shift mechanism (5) that is used for adjusting the transmission ratio of the speed change gear set (33); the clutch (2) is connected between a driving gear (11) and the main shaft (31); the controller (4) is electrically connected to the motor (1) and used for controlling the output power of the motor. Also disclosed is an electric motorcycle, comprising a battery (100), a rear rim (200), and an electrically-driven power unit (300). By using a motor as a power source, the electrically-driven power unit and the electric motorcycle can obtain different output torques of different gears in combination with a clutch by means of a transmission in order to meet the requirements of different road conditions, and can ensure a strong driving force and reasonable energy consumption while meeting the speed requirement.
