The invention discloses a power assembly, a control method of the power assembly and a vehicle. The power assembly comprises a driving motor, a power transmission device and a control device, the planet carrier is connected with the planet gear, and the driving motor is in transmission connection with the sun gear; the first transmission shaft is connected with the planet carrier, and the first transmission shaft is suitable for being in transmission connection with a right wheel; the second transmission shaft is in transmission fit with the gear ring and is suitable for being in transmission connection with a left wheel; and the brake is selectively combined with at least one of the gear ring and the planet carrier so as to adjust the rotating speed of the gear ring and the planet carrier. Therefore, by arranging the brake and enabling the brake to be selectively combined with at least one of the gear ring and the planet wheel, the rotating speed of the left wheel and the rotating speed of the right wheel are adjusted by adjusting the rotating speed of the gear ring and the rotating speed of the planet carrier, the differential function of the power assembly can be achieved without arranging a differential mechanism, and the performance of the power assembly can be guaranteed. And the power assembly is lighter.
本发明公开了一种动力总成、动力总成的控制方法和车辆,动力总成包括:驱动电机;行星齿轮组件,行星架与行星轮相连,驱动电机与太阳轮传动连接;第一传动轴,第一传动轴与行星架相连,第一传动轴适于与右车轮传动连接;第二传动轴,第二传动轴与齿圈传动配合,第二传动轴适于与左车轮传动连接;制动器,制动器选择性地与齿圈和行星架中的至少一个结合,以调节其转速。由此,通过设置制动器,并且使制动器选择性地与齿圈和行星轮中的至少一个相结合,从而通过调节齿圈和行星架的转速来调节左车轮和右车轮的转速,这样无需设置差速器也能实现动力总成的差速功能,可以在保证性能的同时,使得动力总成更加轻量化。
