Drive Axle Assembly with a Collar Actuator Mechanism
First Claim
Patent Images
1. A drive axle assembly comprising:
- a housing;
an input shaft that is disposed in the housing and configured to rotate about an axis;
a first gear that is disposed proximate the input shaft;
a collar that is disposed proximate the first gear; and
a collar actuator mechanism that includes an electromagnetic coil that is disposed in a stationary position with respect to the housing, wherein the electromagnetic coil is configured to actuate the collar between a first position in which the collar is disengaged from the first gear and a second position in which the collar engages the first gear.

10. A drive axle assembly comprising:
-
a housing; an input shaft disposed in the housing and configured to rotate about a first axis; an interaxle differential unit that is disposed on the input shaft; a first gear that is rotatably disposed on the input shaft and operatively coupled to the interaxle differential unit; a collar that is moveably disposed on the input shaft; and a collar actuator mechanism that includes; an electromagnetic coil disposed in a stationary position on the housing; and a biasing member exerts a biasing force that biases the collar away from the first gear; wherein the electromagnetic coil is configured to actuate the collar between a first position in which the collar is disengaged from the first gear and a second position in which the collar engages the first gear such that torque is transmitted from the input shaft to the first gear via the collar. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
