Abstract
An axle assembly having a shift mechanism. The shift mechanism includes an actuator that is configured to move the shift collar along the axis to selectively connect a member of a set of drive pinion gears to a drive pinion. A drive member is also provided that is configured to move the shift collar when actuated.
Claims20
An axle assembly comprising:
- a drive pinion that is rotatable about an axis;
- a transmission that includes a set of drive pinion gears that is spaced apart from the drive pinion and is rotatable about the axis;
- and
- a shift mechanism that includes:
- a shift collar that is rotatable about the axis with the drive pinion and moveable along the axis with respect to the drive pinion;
- an actuator that is configured to move the shift collar along the axis to selectively connect a member of the set of drive pinion gears to the drive pinion;
- a linkage that is operatively connected to the actuator and the shift collar and is rotatable about an actuator axis, the linkage having a linkage gear;
- and
- a drive member that is rotatable about a drive member axis, wherein the drive member has a drive member gear that has teeth that mesh with teeth of the linkage gear, wherein the shift collar is moveable along the axis when the actuator rotates the linkage and when the drive member is manually actuated to rotate the linkage.
