Common types of electric drive systems for new energy commercial vehicles are mainly central integrated electric drive systems, wheel-side electric drive axles, and integrated electric drive axles. Among them, the central integrated coaxial electric drive axle is used for medium-sized and heavy-duty trucks and wide-body dump trucks. The wheel-side electric drive axle is often used in the bus series with a length of more than 10 m. Integrated electric drive axles are often used in trucks and 6 m ~ 7 m minibus series. The integrated electric drive axle is divided into three types: parallel axis, coaxial, and vertical axis. Among them, the drive motor of the vertical axis integrated electric drive axle is connected to the drive axle at a vertical angle, and the hyperboloid gear reduction method is adopted, the speed ratio is small, and the system power density is low. The parallel shaft integrates the electric drive axle, the motor and the drive axle are arranged in a parallel state, and the motor is multi-biased. Cylindrical gear transmission is mostly used, with large speed ratio and high power density; due to the large unsprung mass and offset, the vehicle’s handling and comfort are poor. The domestic integrated electric drive axle mostly adopts the parallel shaft type. Compared with the central drive system, the integrated electric drive axle has a higher degree of integration in terms of motors, reducers, differentials and axles; the design and control of automatic transmissions and the control technology of electric drive systems are less difficult; the chassis takes up less space, and the battery Convenient layout; high energy recovery can be achieved, light weight, 10% to 25% lower than central drive, effectively reducing power consumption, high motor speed, small size, and high power density. However, the motor and gearbox are under the suspension, and the unsprung mass is large, which is not conducive to improving the handling and comfort of the vehicle. The development of automatic transmission design and control, electric drive system control technology, and commercial vehicle drive axle is very difficult. The motor and gearbox of the central drive system are on the suspension, the unsprung mass is small, and the vehicle’s handling and comfort are high. The design and control of automatic transmission, and the development of electric drive system control technology are less difficult.
