A system for selectively locking two coaxial axle shafts of an electric axle is provided. The system includes a first electric motor having a first rotor shaft configured to drive a first axle shaft. The system also includes a second electric motor having a second rotor shaft configured to drive a second axle shaft that is coaxial with the first axle shaft. The actuator is configured to be selectively activated to operate in a safe mode. The actuator locks the first rotor shaft to the second rotor shaft when operated to assume a safe mode such that both shafts rotate in unison. This allows one of the two motors to drive the two axle shafts in the event of a failure of one of the motors.
提供了一种用于选择性地锁定电动车桥的两个同轴的车桥轴的系统。所述系统包括第一电动马达,所述第一电动马达具有构造成驱动第一车桥轴的第一转子轴。所述系统还包括第二电动马达,所述第二电动马达具有构造成驱动与所述第一车桥轴同轴的第二车桥轴的第二转子轴。致动器构造成选择性地启用以在安全模式下操作。所述致动器在被操作成采取安全模式时使所述第一转子轴锁定至所述第二转子轴,使得两个轴一致地旋转。这允许两个马达中的一个马达在马达中的一个马达出现故障的情况下驱动两个车桥轴。
