ABSTRACT:
An electric brake cable tensioning device is disclosed including a planetary gear train driven by a motor driven worm gear and a friction brake for holding a sun gear of the gear train against rotation during torque input. The cable is attached to a planet gear of the gear train which moves around the braked sun gear and pulls the cable in tension. The worm gear and braked sun gear hold the planet gear and cable in the tensioned position. Cable tension is released upon release of the sun gear whereupon the planet gear moves back to the untensioned position.
