Abstract

The invention provides a driving device and a vehicle, the device comprises a driving part, a transmission assembly, a driving controller and a variable speed controller, the driving part comprises N sets of driving assemblies, the transmission assembly comprises a power output shaft and N sets of variable speed assemblies, and the power output end of each set of driving assembly is used for inputting driving force to the corresponding variable speed assembly; a synchronizer and M input gears are arranged on the speed change input shaft of each set of speed change assembly, M output gears are arranged on the power output shaft, and the input gears are meshed with the output gears so that when the output gears are used for bearing driving force, output power of the corresponding gears can be output through the power output shafts. The synchronizer is used for adjusting the output gear currently used for bearing the driving force; the driving controller is used for controlling the working state of each group of driving components, and the variable speed controller is used for controlling the synchronizer to perform gear shifting operation. According to the driving device, mechanical decoupling between the motors is achieved, the transmission efficiency is high, power interruption is avoided during gear shifting, and control is relatively simple.

Description

technical field [0001] The present application relates to the technical field of automobile transmission, in particular to a driving device and a vehicle. Background technique [0002] Electric vehicles are powered by on-board power supplies and driven by motors. Due to its remarkable advantages of cleanliness and energy saving, electric vehicles have become an emerging industry that all countries in the world pay more attention to, and their application prospects are very good. In the application field of electric large-tonnage vehicles, the vehicle has the requirement of both large output torque and high speed. [0003] Most of the existing pure electric heavy-duty truck schemes still use a single high-torque, low-speed drive motor with a fixed speed ratio reduction device, which has the disadvantages of heavy weight, high manufacturing cost, insufficient power performance at medium and high speeds, and low-speed There are problems such as narrow high-efficiency zone and...
