Document Type and Number:
WIPO Patent Application WO/2024/001247
Kind Code:
A1
Abstract:
An electric-drive gearbox with two electric motors and uninterrupted power during gear shifting, and a vehicle. The electric-drive gearbox with two electric motors comprises a first intermediate rotating shaft (30), a second intermediate rotating shaft (40), an output shaft (70), a first intermediate shaft gear mechanism, a second intermediate shaft gear mechanism, a first gear shifting mechanism (K1), a second gear shifting mechanism (K2) and a third gear shifting mechanism (K3). The electric-drive gearbox with two electric motors and uninterrupted power during gear shifting and the vehicle can solve the problem of power interruption during gear shifting. In addition, the first intermediate rotating shaft and the second intermediate rotating shaft of the electric-drive gearbox with two electric motors and uninterrupted power during gear shifting can be configured in the form of two solid shafts, that is, the first intermediate rotating shaft does not need to be configured as a hollow tubular structure, and the second intermediate rotating shaft also does not need to pass through the first intermediate rotating shaft, such that the intermediate rotating shafts have a simple structure and are stable and reliable.
