Title:
COAXIAL ELECTRIC DRIVE AXLE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/206718
Kind Code:
A1
Abstract:
A coaxial electric drive axle and a vehicle. The coaxial electric drive axle comprises at least one motor (1, 2), at least one transmission assembly (3), a main shaft (4), and two axle shafts (15, 16) connected by means of a differential (14). Each motor (1, 2) is in transmission connection to the corresponding transmission assembly (3). When the coaxial electric drive axle is in a transmission mode, each transmission assembly (3) is in transmission connection to the main shaft (4) or a housing of the differential (14); the motor (1, 2), the main shaft (4) and the two axle shafts (15, 16) have the same axis. In the coaxial electric drive axle and the vehicle, the motor (1, 2) transmits power to the first axle shaft (15) and the second axle shaft (16) by means of the transmission assembly (3), and the motor (1, 2), the main shaft (4) and the axle shafts (15, 16) have the same axis, so that the coaxial electric drive axle has a novel and compact structural layout, a short power transmission chain, and high transmission efficiency; a plurality of motors (1, 2) can carry out both independent driving and combined driving, thus achieving various power output modes, ensuring efficient running of a vehicle, and satisfying the power demands of diversified loads and various working conditions of commercial vehicles.
