Dual-clutch assembly, hybrid power system, and vehicle

A hybrid power system, comprising a dual-clutch assembly, an engine, a first motor, a first gear train, and a second gear train, wherein the dual-clutch assembly comprises a first rotating shaft, a second rotating shaft, a hollow shaft, a first clutch, and a second clutch;

• wherein the first rotating shaft and the second rotating shaft are arranged coaxially at intervals, and the hollow shaft is sleeved outside the second rotating shaft;
• wherein the first clutch is between the first rotating shaft and the second rotating shaft, a driving part of the first clutch is connected with the first rotating shaft, and a driven part of the first clutch is connected with the second rotating shaft;
• and
• wherein a driving part of the second clutch is on one side, away from the second rotating shaft, of the first clutch and is connected with the first rotating shaft, wherein the one side is away from the second rotating shaft, and wherein a driven part of the second clutch is connected with the hollow shaft;
• wherein the engine and the first motor are both in transmission connection with the first rotating shaft;
• wherein an input gear of the first gear train is coaxially connected with the second rotating shaft, an input gear of the second gear train is coaxially connected with the hollow shaft, and an output gear of the first gear train and an output gear of the second gear train are both in transmission connection with a wheel;
• wherein the hybrid power system further comprises a second motor and a third rotating shaft;
• wherein the second motor is in transmission connection with the third rotating shaft;
• and
• wherein the output gear of the first gear train and the output gear of the second gear train are both coaxially sleeved outside the third rotating shaft, and the third rotating shaft is in transmission connection with the wheel.
