HYBRID DRIVING SYSTEM

摘要

A series/parallel bi-motor dual-clutch hybrid electrical driving unit for automobile includes: a main drive motor (17), an integrated starter-generator (4), a differential (7), a spindle (8), a first stage decelerating device (9), a primary clutch (16) and a first clutch (15). Said drive motor (17) is connected with said first stage decelerating device (9) via said first clutch (15). A series/parallel bi-motor tri-clutch hybrid electrical driving unit for automobile further includes a second clutch (12) and a second stage decelerating device (5) based on the above described series/parallel bi-motor dual-clutch hybrid electrical driving unit. The hybrid electrical driving unit according to the invention is compact in structure arrangement, high efficient and rational in connection, realizes a switch between connection and disconnection of hybrid power sources and wheels, and realizes a switch of hybrid driving system working modes and gearshifts by varying power-output torque.
