    • A vehicle driveline component with an actuator and a rotary coupling. The actuator has an actuator housing, a motor, a transmission, a first cam, a second cam, and a first biasing spring. The motor is coupled to the actuator housing and includes a motor output member. The transmission has a transmission input member, which is driven by the motor output member, and a transmission output member. The first cam is housed in the actuator housing and is coupled to the transmission output member for rotation therewith. The first cam has a first set of cam features that are disposed about a first annular surface. The second cam has a cam body, which is received in the first cam, and a second set of cam features that are disposed about a second annular surface. The second set of cam features abut the first set of cam features. Rotation of the first cam relative to the second cam into a first position orients the first set of cam features onto the second set of cam features so as to position the second cam in an extended position relative to the first cam. Rotation of the first cam relative to the second cam into a second position orients the first set of cam features onto the second set of cam features so as to position the second cam in a retracted position relative to the first cam. The first biasing spring is disposed between the first and second cams and biases the second cam toward the retracted position. The rotary coupling has a first coupling member, a second coupling member and a second biasing spring. The first coupling member is rotatably and axially slidably received in the second cam. The first coupling member is axially movable between a first coupling position, in which the first coupling member is decoupled from the second coupling member, and a second coupling position in which the first coupling member is coupled to the second coupling member to permit the transmission of rotary power through the rotary coupling. The second biasing spring is disposed between the first coupling member and the second cam.
    • 具有致动器和旋转联轴器的车辆传动部件。 致动器具有致动器壳体,电动机,变速器,第一凸轮,第二凸轮和第一偏置弹簧。 电动机联接到致动器壳体并且包括电动机输出构件。 变速器具有由电动机输出构件驱动的变速器输入构件和变速器输出构件。 第一凸轮容纳在致动器壳体中并且联接到变速器输出构件以与其一起旋转。 第一凸轮具有围绕第一环形表面设置的第一组凸轮特征。 第二凸轮具有容纳在第一凸轮中的凸轮体,以及围绕第二环形表面设置的第二组凸轮特征。 第二组凸轮特征与第一组凸轮特征相邻。 第一凸轮相对于第二凸轮旋转到第一位置将第一组凸轮特征定位到第二组凸轮特征上,以便将第二凸轮相对于第一凸轮定位在延伸位置。 第一凸轮相对于第二凸轮旋转到第二位置将第一组凸轮特征定位到第二组凸轮特征上,以将第二凸轮相对于第一凸轮定位在缩回位置。 第一偏置弹簧设置在第一和第二凸轮之间,并且将第二凸轮朝向缩回位置偏压。 旋转联轴器具有第一联接构件,第二联接构件和第二偏置弹簧。 第一联接构件可旋转并轴向可滑动地容纳在第二凸轮中。 第一联接构件可以在第一联接位置和第二联接位置之间轴向移动,在第一联接位置,第一联接构件与第二联接构件分离,第二联接构件将第一联接构件联接到第二联接构件, 旋转动力通过旋转联轴器。 第二偏置弹簧设置在第一联接构件和第二凸轮之间。
