    • A transmission assembly (16, fig 3 ) is powered by an electric motor (10, fig 2 ) and includes a transmission having an outer ring gear, a connector (52) moveable relative to the outer ring gear (38) between a first position, in which the connector (52) is rotatable with the transmission (34) in response to torque received from the motor (10), and a second position, in which the connector (52) and the outer ring gear (38) are non-rotatable, and a control mechanism (160) operable to detect the operating current of the motor (10) and compare the operating current to a threshold current. The control mechanism (160) is operable to move the connector (52) from the first position to the second position in response to the motor (10) operating current exceeding the threshold current.
    • 变速器组件(图3中的16)由电动机(图2中的10)供电,并且包括具有外圈齿轮的变速器,可相对于外齿圈(38)移动的第一位置 ,其中所述连接器(52)响应于从所述马达(10)接收到的扭矩而可与所述变速器(34)一起旋转;以及第二位置,其中所述连接器(52)和所述外齿圈(38)不是 以及可操作以检测电动机(10)的工作电流并将工作电流与阈值电流进行比较的控制机构(160)。 控制机构(160)可操作以响应于电动机(10)超过阈值电流的工作电流而将连接器(52)从第一位置移动到第二位置。
