Description

technical field [0001] The invention relates to a hybrid drive system, and the invention also relates to a vehicle having such a system. Background technique [0002] A HEV has a powertrain that uses two or more on-board energy sources, including electricity. The hybrid car using the traditional internal combustion engine and battery as the power system has become a hotspot in the current automotive power system technology research due to its advantages of low energy consumption, low emission and relatively low price. [0003] The Chinese patent with the publication number CN1637327 discloses a hybrid drive system, which includes a dual-clutch transmission and a motor, wherein the motor is directly connected to the hollow input shaft of the transmission. In this case, the arrangement of the motor is relatively complicated, and the space utilization is not very reasonable , and the hollow input bearing is subjected to excessive torque, which may cause the fracture of the hol...
