The invention provides a vectoring axle drive. An electrical vehicle includes an electric machine and a vectoring motor that propel the vehicle. The vectoring motor drives a right axle shaft and a left axle shaft axle through a torque multiplier. First and second planetary gear sets are connected to right and left ends of a linking shaft that extends through a central opening defined by a rotor and a tubular output shaft of the motor. Torque is provided through the linking shaft to the first and second planetary gear sets. First and second grounding clutches normally lock the first and second planetary gear sets to a case of the vectoring motor. The grounding clutches are selectively and partially released to allow the ring gear of one of the first and second planetary gear sets to reduce a torque output of one of the first and second planetary gear sets to right and left axle shafts.

    本公开提供了“矢量控制车桥驱动装置”。一种电动车辆包括推进车辆的电机和矢量控制马达。所述矢量控制马达通过扭矩倍增器驱动右车桥轴和左车桥轴。第一行星齿轮组和第二行星齿轮组连接到连杆轴的右端和左端,所述连杆轴延伸穿过由马达的转子和管状输出轴限定的中心开口。通过连杆轴向第一行星齿轮组和第二行星齿轮组提供扭矩。第一接地离合器和第二接地离合器通常将第一行星齿轮组和第二行星齿轮组锁定到矢量控制马达的外壳。所述接地离合器被选择性地且部分地释放以允许第一行星齿轮组和第二行星齿轮组中的一者的环形齿轮减小第一行星齿轮组和第二行星齿轮组中的一者到右车桥轴和左车桥轴中的扭矩输出。
