    • A power takeoff unit transmits torque taken from a transmission of a vehicle to an output shaft. The power takeoff unit is comprised of a casing combinable with the transmission at a first end; a first shaft receiving the torque about a first axis; a second shaft rotatable about the first axis; a clutch slidably fitting with the second shaft and being directed to the first shaft, the clutch being movable along the first axis between a first position to interrupt transmission of the torque and a second position to transmit the torque from the first shaft to the second shaft; a first gear projecting from the bearing toward the first end and being rotatable along with the second shaft without any support excepting the bearing; and a third shaft including a second gear meshing with the first gear, thereby outputting the transmitted torque.
    • 动力输出单元将从车辆的变速器获取的扭矩传递到输出轴。 动力输出单元由在第一端与变速器组合的壳体构成; 接收围绕第一轴线的转矩的第一轴; 可绕第一轴线旋转的第二轴; 离合器,其与所述第二轴滑动配合并被引导到所述第一轴,所述离合器可沿着所述第一轴线在第一位置和第二位置之间移动,以阻止所述扭矩的传递;以及第二位置,用于将所述扭矩从所述第一轴传递到所述第二轴 ; 第一齿轮从所述轴承向所述第一端突出并且与所述第二轴一起旋转,而不包括所述轴承之外的任何支撑件; 以及包括与第一齿轮啮合的第二齿轮的第三轴,从而输出传递的扭矩。
