The invention provides a new energy automobile power assembly, and belongs to the technical field of new energy automobile power systems. According to the new energy automobile power assembly, the disc type motor and the radial motor are adopted to provide power for the speed reducer, low-speed power performance and high-low-speed energy-saving performance can be both considered, specifically, the clutch is detachably connected with the disc type motor and the speed reducer, the output end of the radial motor is connected with the speed reducer, and the output end of the radial motor is connected with the speed reducer. The new energy automobile power assembly has two power modes, the first mode is that the clutch is disconnected, only the radial motor is adopted for providing power for the speed reducer, the second mode is that the clutch is closed, the disc type motor and the radial motor provide power for the speed reducer at the same time, and due to the fact that the torque density of the disc type motor is high, better power performance experience can be provided; and the conditions of slope climbing and slope slipping are avoided, and good acceleration performance is achieved.
本申请提供了一种新能源汽车动力总成,属于新能源汽车动力系统技术领域。本申请实施例提供的新能源汽车动力总成,采用盘式电机和径向电机向减速器提供动力,能够兼顾低速动力性能和高低速节能性能,具体地,采用离合器可拆卸的联接盘式电机和减速器,且径向电机的输出端联接减速器,使该新能源汽车动力总成具有两种动力模式,第一种:离合器断开,只采用径向电机为减速器提供动力,第二种,离合器闭合,盘式电机和径向电机同时为减速器提供动力,由于盘式电机的转矩密度较高,可以提供更好的动力性能体验,避免出现爬坡溜坡的情况,具有较好的加速性能。
