AI Technical Summary
Existing electric motor hybrid power systems suffer from structural problems such as low efficiency, large size, and heavy weight. Furthermore, parallel hybrid systems are expensive and difficult to integrate and achieve cost-effectiveness.
The system employs an engine, a first motor, a second motor, a first clutch, a second clutch, an input gear, and an intermediate shaft transmission assembly. By coaxially configuring the first clutch and the second clutch and sharing the same outer hub, combined with a differential, a drive system with multiple operating modes is formed.
It achieves high integration and compact structure of the drive system, and has single-motor pure electric, dual-motor pure electric, series hybrid and parallel hybrid modes, which are suitable for hybrid and plug-in hybrid vehicles, improving power and economy.
