Abstract
A power transmitting component having a actuator with a lead screw, which is driven by a motor and a transmission, a pusher assembly driven by the lead screw, and a clutch fork. Translation of the pusher coordinates movement of the clutch fork along its axis.
Claims10
A power transmitting component comprising:
- an actuator housing;
- a motor coupled to the actuator housing;
- a transmission driven by the motor, the transmission being at least partially housed in the actuator housing;
- a lead screw that is rotatable about a first axis, the lead screw being driven by the transmission;
- a first rail extending along a second axis that is generally parallel to the first axis;
- a second rail extending along a third axis that is generally parallel to the first axis;
- a cradle assembly driven by the lead screw axially along the first axis, the cradle assembly comprising a cradle, a cradle body and a cradle spring, the cradle having a first cradle yoke that is slidably received on the first rail, the cradle body being received in the cradle and threadably coupled to the lead screw, the cradle spring resiliently coupling the cradle body to the cradle;
- and
- a clutch fork slidably mounted on the second rail;
- wherein movement of the cradle along the first rail coordinates movement of the clutch fork along the third axis.

A power transmitting component comprising:
- a power take-off unit having a mode clutch, the mode clutch having a mode member that is axially movable along a power transmitting axis between a first mode position, in which no rotary power is transmitted through the mode clutch, and a second mode position in which rotary power is transmitted through the mode clutch;
- and
- an actuator having an actuator housing, a motor coupled to the actuator housing, an actuator transmission, a lead screw, a first rail, a second rail, a cradle assembly, and a clutch fork, the actuator transmission being driven by the motor and being at least partially housed in the actuator housing, the lead screw being driven by the transmission about a first axis, the first rail extending along a second axis that is generally parallel to the first axis, the second rail extending along a third axis that is generally parallel to the first axis, the cradle assembly being driven by the lead screw axially along the first axis, the cradle assembly comprising a cradle having a first cradle yoke, which is slidably received on the first rail, a cradle body and a cradle spring, the cradle body being received in the cradle and threadably coupled to the lead screw, the cradle spring resiliently coupling the cradle body to the cradle, the clutch fork being slidably mounted on the second rail, the clutch fork being engaged to the mode member such that movement of the clutch fork along the third axis causes corresponding movement of the mode member along the power transmitting axis;
- wherein movement of the cradle along the first rail coordinates movement of the clutch fork along the third axis.
