ABSTRACT:
The specification discloses a transmission system for a press. A rotatable shaft is mounted within an oil lubrication housing and a flywheel is rotatably mounted in the housing about the shaft. A shaft extends through the oil housing for transmitting rotation to the flywheel within the oil housing. Low and high speed clutch assemblies are spaced apart along the shaft and include pistons selectively movable to engage the clutch assemblies. Gears are provided to transmit rotation from the flywheel to the clutch assemblies. A brake assembly is mounted between the clutch assemblies and includes friction surfaces carried about the shaft. The brake assembly also includes a stationary housing mounted about the friction surfaces and engaging the friction surfaces to brake the shaft when the friction surfaces are engaged. Brake plates are mounted on opposite sides of the brake assembly for causing engagement of the friction surfaces. Structure rigidly interconnects adjacent pistons and brake plates such that the friction surfaces are disengaged when either of the clutch assemblies are engaged.
