Abstract:
The present disclosure relates to a combined hydraulic motor and brake including a hydraulic motor having a hydraulic motor housing, a drive shaft assembly that is driven by the hydraulic motor, a stationary housing that is fixed relative to the hydraulic motor housing, and a rotatable housing that is rotatably driven by the drive shaft assembly. The combined hydraulic motor and brake also includes a brake for resisting relative rotation between the rotatable housing and the stationary housing, and a piston that is hydraulically actuated to release the brake. The piston is carried with the rotatable housing such that the piston, the rotatable housing and at least a portion of the drive shaft assembly are configured to rotate as a unit.
