The invention discloses a double-motor stepless speed regulation power system which is characterized in that a first sun gear is connected with a second motor, a first planet gear is respectively matched with the first sun gear and a first gear ring, the first gear ring is fixed with a shell, one end of a first planet carrier is connected with the first planet gear, and a second planet gear is respectively matched with a second sun gear and a second gear ring; one end of the second planet carrier is connected with the second planet gear, the first motor is connected with the second sun gear, the other end of the first planet carrier is connected with the second gear ring, and the other end of the second planet carrier is a power output end; and the automatic disconnecting and combining device is respectively matched with the shell and the second gear ring. The method has the advantage that a corresponding execution element control system does not need to be additionally configured for the automatic disconnection and connection device. The first motor and the second motor can realize speed coupling, namely stepless speed regulation, and are suitable for high-efficiency working areas of multi-working-condition regulation motors, energy consumption is reduced while large power is provided, and better NVH performance is obtained at the same time.
本发明公开了一种双电机无级调速动力系统,第一太阳轮与第二电机连接,第一行星轮分别与第一太阳轮和第一齿圈配合,第一齿圈与壳体固定,第一行星架的一端与第一行星轮连接,第二行星轮分别与第二太阳轮和第二齿圈配合,第二行星架的一端与第二行星轮连接,第一电机与第二太阳轮连接,第一行星架的另一端与第二齿圈连接,第二行星架的另一端为动力输出端;自动断开与结合装置分别与壳体和第二齿圈配合。本发明具有不需要为自动断开与结合装置另行配置相应的执行元件控制系统的优点。第一电机和第二电机可实现速度耦合即无级调速,适应多工况调节电机的高效工作区,提供较大动力的同时降低能量消耗,同时获得更好的NVH性能。
