Abstract:
1. A brake actuator mechanism, comprising: an inner shaft having a first portion connected to a clutch mechanism and a second portion distally opposite said first portion and having a first circumferential ring; an outer shaft overlapping at least a portion of said second portion of said inner shaft, said outer shaft terminating at said first circumferential ring of said inner shaft so that said outer shaft does not overlap said clutch mechanism; a second ring disposed between said inner shaft and said outer shaft, said second ring having at least one raised surface for selectively coupling said inner shaft and said outer shaft; wherein said second ring is compressed between said inner shaft and said outer shaft and couples said inner shaft and said outer shaft via a frictional engagement to a pre-determined torsional limit, and beyond said pre-determined torsional limit said second ring allows said outer shaft to rotate with respect to inner shaft.
