Side hung driving system for two-wheeled electric vehicle

Abstract

The invention relates to a two-wheeled electric vehicle, and in particular to a driving system for the two-wheeled electric vehicle, wherein, the driving system comprises a motor and a variable speed drive device. The driving system is characterized in that the variable speed drive device comprises a motor shaft, an intermediate shaft, a variable-speed shaft and an output shaft, wherein, the motor shaft, the intermediate shaft and the variable-speed shaft are sequentially arranged on the same side and connected with each other through gears connected in a meshing manner; the output shaft is connected with a hub; change gear sets which are meshed with each other are arranged on the intermediate shaft and the variable-speed shaft; and an overrunning clutch and a gear shifting device are arranged on the variable-speed shaft. By adopting the technical scheme in the invention, the side hung driving system for the two-wheeled electric vehicle is convenient to adjust the speed and the torque and can achieve good climbing performance, and the overrunning clutch is not easy to damage.

Description

technical field [0001] The invention relates to a two-wheel electric vehicle, and more specifically, relates to a driving system of the two-wheel electric vehicle. Background technique [0002] A two-wheeled electric vehicle is a means of transportation driven by a motor and a transmission system using a battery as energy. Compared with a bicycle, it does not require human pedaling and saves effort. Compared with a motorcycle and other internal combustion engine-driven vehicles, it has low noise. , no waste gas, less pollution. Therefore, as a cheap and good-quality, easy-to-use means of transportation, it quickly spreads to millions of households and becomes a means of transportation for ordinary people to travel in short distances. [0003] The existing two-wheeled electric vehicles generally use the wheel motor, which is directly driven by a low-speed DC motor. Obtained, when encountering climbing, the result is that the climbing performance of the two-wheeled electric ...

AI Technical Summary

Problems solved by technology

[0003] The existing two-wheeled electric vehicles generally use the wheel motor, which is directly driven by a low-speed DC motor. Obtained, when encountering climbing, the result is that the climbing performance of the two-wheeled electric vehicle is poor, and the battery life of the electric vehicle will be low, and even cause damage to the battery. If the overload is too large, the hub motor may be burned

[0004] There are also a small number of two-wheeled electric vehicles that adopt the side-mounted drive method, using the combination of the motor and the transmission gear set, but because the transmission link is set at the final stage, the overrunning clutch is set on the final output shaft, resulting in the overrunning clutch. The larger torque is usually 150N·m, while the torque that the existing overrunning clutch can carry is generally around 50N·m, which eventually leads to more failures of the overrunning clutch
