Abstract
An axle assembly having a clutch collar actuator mechanism. The clutch collar actuator mechanism may have a piston housing and a yoke that may move with respect to the piston housing. The piston housing may extend around the input shaft and may receive at least one piston. The yoke may connect the piston to the clutch collar.
Claims20
An axle assembly comprising:
- a differential carrier;
- a cover disposed on the differential carrier;
- an input shaft that extends through the cover and is rotatable about an axis;
- an interaxle differential unit disposed on the input shaft;
- a clutch collar moveably disposed on the input shaft;
- a piston housing that is disposed in the differential carrier on the cover, wherein the piston housing has a first piston bore that receives a first piston and a second piston bore that receives a second piston;
- a yoke that connects the first piston and the second piston to the clutch collar;
- and
- a first yoke slide and a second yoke slide that are disposed on the cover and extend through the piston housing to the yoke, wherein the yoke slides along the first yoke slide and the second yoke slide, and the clutch collar moves to an extended position to lock the interaxle differential unit when pressurized fluid is provided to the first piston bore and the second piston bore to actuate the first piston and the second piston.

- a piston housing that is disposed in the differential carrier on the cover, wherein the piston housing has a first piston bore that receives a first piston and a second piston bore that receives a second piston;
- and
- a yoke that connects the first piston and the second piston to the clutch collar, wherein the yoke has a first piston rod that extends through the piston housing into the first piston bore and a second piston rod that extends through the piston housing into the second piston bore, wherein the first piston is disposed on the first piston rod and the second piston is disposed on the second piston rod and the clutch collar moves to an extended position to lock the interaxle differential unit when pressurized fluid is provided to the first piston bore and the second piston bore to actuate the first piston and the second piston.

An axle assembly comprising:
- a differential carrier;
- a cover disposed on the differential carrier;
- an input shaft that extends through the cover and is rotatable about an axis;
- an interaxle differential unit disposed on the input shaft;
- a clutch collar moveably disposed on the input shaft, wherein the clutch collar has a clutch collar hole that receives the input shaft and an inner annular groove that faces toward the input shaft, wherein the inner annular groove receives a retainer that has a retainer hole that receives the input shaft, wherein the inner annular groove inhibits axial movement of the retainer with respect to the clutch collar;
- a piston housing that is disposed in the differential carrier on the cover, wherein the piston housing has a first piston bore that receives a first piston and a second piston bore that receives a second piston;
- and
- a yoke that connects the first piston and the second piston to the clutch collar;
- wherein the clutch collar moves to an extended position to lock the interaxle differential unit when pressurized fluid is provided to the first piston bore and the second piston bore to actuate the first piston and the second piston.
