ABSTRACT:
High and low speed clutch assemblies are spaced apart along a rotatable shaft. Each of the clutch assemblies includes a plurality of annular friction plates which may be engaged by movement of annular pistons. A brake assembly is mounted between the clutch assemblies and includes friction surfaces carried about the rotatable shaft and annular brake plates mounted on opposite sides of the friction surfaces. A stationary housing is mounted about the brake assembly. Adjacent ones of the pistons and the brake plates are interconnected, such that the friction surfaces of the brake assembly are disengaged when either of the clutch assemblies are engaged by application of fluid pressure. The pistons and brake plates are spring-loaded such that when both of the clutch assemblies are disengaged, the brake plates move to engage the friction surfaces with the stationary housing to brake the shaft.
