Abstract

A vehicle driveline component includes a case defining lever apertures, a coupling having a movable member that is movable along a movement axis between a first and a second position, a linear having a motor output member movable along the movement axis, and a plurality of levers. Each lever is disposed in an associated lever aperture and coupled to the case for pivoting motion about a respective lever pivot axis. The levers urge the movable member in a first direction along the movement axis from one of the first and second positions to the other one of the first and second positions in response to pivoting motion of the levers about the lever pivot axes caused by contact between the levers and the motor output member when the motor output member is driven in a second direction along the movement axis that is opposite the first direction.

Claims (13)

1. A vehicle driveline component comprising:

a case having a wall member and defining an internal cavity and a plurality of lever apertures, the lever apertures being formed through the wall member and intersecting the internal cavity;

a coupling disposed in the internal cavity in the case, the coupling having a movable member that is movable within the case along a movement axis between a first position and a second position, wherein the coupling is configured to transmit rotary power therethrough when the movable member is in the first position, and wherein transmission of rotary power through the coupling is inhibited when the movable member is in the second position;

a linear motor having a motor output member that is movable along the movement axis; and

a plurality of levers, each of the levers being disposed in an associated one of the of the lever apertures and coupled to the case for pivoting motion about a respective lever pivot axis;

wherein the levers urge the movable member of the coupling in a first direction along the movement axis from one of the first and second positions to the other one of the first and second positions in response to pivoting motion of the levers about the lever pivot axes that is caused by contact between the levers and the motor output member when the motor output member is driven in a second direction along the movement axis that is opposite the first direction;

wherein the linear motor includes an electromagnet coil; and

wherein the electromagnet coil is the motor output member.

2. The vehicle driveline component of claim 1 , further comprising a spring that biases the movable member toward one of the first and second positions.

3. The vehicle driveline component of claim 2 , wherein the spring is disposed along the movement axis between the movable member and the wall member of the case.

4. The vehicle driveline component of claim 1 , further comprising a differential gearset and a differential output member, the differential gearset having a side gear, wherein the coupling comprises a first dog and a second dog, wherein the first dog is fixedly coupled to the side gear, wherein the second dog is fixedly coupled to the differential output member, and wherein the movable member of the coupling is the second dog.

5. The vehicle driveline component of claim 1 , further comprising a housing, wherein the case is disposed in the housing for rotation about the movement axis.

6. The vehicle driveline component of claim 1 , wherein the motor output member is slidably mounted on the case.
