ABSTRACT:
A torque limiter which includes an input shaft and an output shaft coaxial with the input shaft. A ball ramp torque transmitting device is disposed concentrically relative to the shafts. A first spring is axially disposed of the ball ramp device for normally preloading the device. A friction brake assembly is axially disposed between the ball ramp device and the first spring and operatively associated with the output shaft. Pins extend axially through the friction brake assembly for transferring preloading spring force to the ball ramp device. A second spring is disposed on the same side of the friction brake assembly as the first spring and acts on the friction brake assembly. Both springs are mounted about the output shaft whereby the shaft itself carries the loads of the torque limiter.
