AI Technical Summary
Technical Problem
Existing electric drive transmissions suffer from power interruption during gear shifts, affecting vehicle ride comfort and safety.
Method used
The dual-motor electric drive gearbox design constructs three power transmission paths by setting up a first intermediate shaft gear mechanism, a second intermediate shaft gear mechanism, a first central shaft, and a second central shaft. The switching between power transmission paths is achieved by controlling three shifting devices to ensure uninterrupted power during gear shifting.
Benefits of technology
Maintaining power continuity during gear shifts improves vehicle comfort and safety, and reduces shift shock.
