Abstract: Aiming at the problems of poor system integration and low comprehensive energy efficiency in the current mainstream pure electric sanitation vehicle configurations, a multi-mode high-efficiency electric drive system configuration based on the integration of parallel shaft gearbox and planetary row is proposed. By analyzing and comparing the working modes that can be realized by the configuration, the connection method of the configuration is finally determined, and the working modes with different connection modes are analyzed. Based on the dynamic index, the system parameters are matched and the vehicle dynamic model is built. The simulation analysis results show that the maximum climbing slope of this configuration of the pure electric sanitation vehicle can reach 35%, and the acceleration time of 0～50 km/h is 6.1 s, which verifies the effectiveness of the design scheme.
