Electrically driven power plant and electric motorcycle

Abstract

The invention discloses an electrically driven power plant and an electric motorcycle. The electric motorcycle comprises a battery, a rear rim and the electrically driven power plant, wherein the battery is electrically connected to the electrically driven power plant, and the electrically driven power plant is in transmission connection with the rear rim. The electrically driven power plant comprises a motor, a clutch, a speed change mechanism and a controller, wherein the speed change mechanism comprises a main shaft, an auxiliary shaft which is used for outputting power to outside and a speed change gear set which is connected between the main shaft and the auxiliary shaft; a gear shifting mechanism is connected to the speed change gear set and is used for regulating the transmission ratio of the speed change gear set; the clutch is connected between a driving wheel and the main shaft; the controller is electrically connected to the motor and is used for controlling the output power of the motor. The motor is used as a power source, and the clutch and the speed change mechanism are combined, so that different output torques of different gears can be obtained so as to satisfy the requirements of different road conditions, the speed can be satisfied, and additionally, strong power and reasonable energy consumption can be guaranteed.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to an electric drive power device and an electric motorcycle. Background technique [0002] Current electric bicycles have entered a technical bottleneck in terms of climbing ability, driving speed and mileage. The current motor power system in the industry uses a low-speed inner stator and outer rotor hub motor to directly drive the vehicle, and its maximum speed is only about 45Km / h, and the maximum torque is only about 120N.m; for the pursuit of speed, strength and energy consumption at the same time requirements are clearly not met. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an electric drive power device and an electric motorcycle, which can ensure strong power and reasonable energy consumption while satisfying the speed. [0004] In order to solve the above technical problems, on the one hand, an embodiment of the pr...
