A brake assembly includes a housing, a brake element configured to be operatively associated with an axle for resisting rotation of the axle, and a piston configured to be selectively moved into and out of braking engagement with the brake element. The brake assembly further includes a slack adjustment mechanism for limiting movement of the piston when the piston is moved out of braking engagement with the brake element. The slack adjustment mechanism includes a shuttle configured to be engaged by the piston, and a plurality of stop elements carried by the shuttle and configured to be moved off the shuttle into a well of the housing. Movement of the piston is stopped when the shuttle engages an end wall of the well or one of the stop elements in the well.

A final drive includes a planetary gear assembly and at least one bearing. The at least one bearing defines an annulus having an internal space where at least a portion of the planetary gear assembly is located within the internal space.

Final drive assembly

A drive axle assembly is provided that improves lubrication to the components of the drive axle assembly. As the wheel differential rotates, lubricant is splashed and lubricates bearings and other associated components of the differential assembly. In addition, lubricant is pumped by rotation of the first and second spur gears and is fed to the radial face of a forward bearing through a lubrication passage through a plurality of passages.

A mobile machine includes a propulsion system. The propulsion system may include a prime mover, a traction device, and a clutch operable to transmit power produced by the prime mover to the traction device. The propulsion system may also include propulsion-system controls operable to control the clutch. The propulsion-system controls may include at least one information processor configured to estimate a temperature of the clutch based at least in part on an estimated slippage of the clutch and a fluid temperature.
