Torque limiting clutch for drive to cane chopping mechanism in sugar cane harvester. Torque is transmitted through a ball and ramp self servo device. Axial thrust generated by the self servo device is transmitted through hydraulic fluid in a piston and cylinder assembly generating hydraulic pressure proportional to the torque. A pilot operated pressure limiting valve vents the cylinder and thereby stops torque transmission when a predetermined torque is reached. Selective disengagement of the clutch is provided by a manual control valve which vents the cylinder. |
