Multi-gear speed change driving system of electric motorcycle and electric motorcycle adopting multi-gear speed change driving system

Abstract

The invention relates to a multi-gear speed change driving system of an electric motorcycle and the electric motorcycle adopting the multi-gear speed change driving system. The multi-gear speed change driving system comprises a machine seat case, a driving motor, a speed changer and a clutch, wherein the driving motor is fixedly arranged at the machine seat case, the clutch is in transmission connection with a motive power output shaft of the driving motor and an input shaft of the speed changer, and the speed changer is a multi-gear speed changer with at least three gears. The multi-gear speed change driving system of the electric motorcycle and the electric motorcycle adopting the multi-gear speed change driving system have the advantages that the driving motor and the multi-gear speed changer are integrally designed, different speed ratios are matched by aiming at different road conditions through operating the speed changer, the energy utilization rate is improved, the endurance mileage of the electric motorcycle is improved, the work voltage stability of the driving motor and a storage battery is ensured, and the service lives of the driving motor, a controller and the storage battery are prolonged.

Description

technical field [0001] The invention relates to an electric motorcycle driving system and the electric motorcycle, in particular to an electric motorcycle multi-speed variable speed driving system and the electric motorcycle. Background technique [0002] Electric motorcycle is a zero-emission, low-noise, light-weight means of transportation, suitable for use on smooth roads and low driving speeds. It is widely used in cities, but compared with fuel motorcycles, it has lower There is a large gap in terms of capacity and cruising range. In order to free up more space for driving and control and improve driving comfort in the prior art, most of the drive systems of electric motorcycles are directly driven by hub drive motors. Adjust the input voltage or current of the hub drive motor to control its output torque and speed to meet the requirements of different road conditions and vehicle speeds.

[0002] Electric motorcycle is a zero-emission, low-noise, light-weight means of transportation, suitable for use on smooth roads and low driving speeds. It is widely used in cities, but compared with fuel motorcycles, it has lower There is a large gap in terms of capacity and cruising range. In order to free up more space for driving and control and improve driving comfort in the prior art, most of the drive systems of electric motorcycles are directly driven by hub drive motors. Adjust the input voltage or current of the hub drive motor to control its output torque and speed to meet the requirements of different road conditions and vehicle speeds. Applicable; when going uphill, the load is heavy, it is easy to cause a sharp increase in current, it is easy to burn the controller and the drive motor, and it also directly affects the life of the battery, and the overall driving efficiency is low under various road conditions, the cruising range is short, and the acceleration performance Poor, weak climbing energy, which limits the scope and promotion of electric motorcycles
