AI Technical Summary
The existing four-wheel drive system of range-extended electric vehicles requires the addition of a drive motor, resulting in high costs and demanding space requirements.
A dual-shaft extension generator replaces the traditional single-function generator. Utilizing the motor's single main shaft and exposed shaft extensions at both ends, combined with the motor's bidirectional working characteristics of generating electricity and driving electrically, and equipped with a two-stage clutch component, a single motor can be used for dedicated power generation and temporary auxiliary drive functions, avoiding the need for additional drive motors and their supporting structures.
Reduce the cost of range-extended drives, improve their flexibility and stability in complex road conditions, reduce hardware costs and front compartment space occupation, and improve system reliability.
