Abstract
The invention is directed to a freewheel clutch which transmits torque in two directions of rotation and controls the blocking pawls by control rings which are held back by friction rings ounter to the rotary motion and by guide extensions and pivot journals of blocking pawls guided in radial slots in guide extensions which move the blocking pawls out of or into engagement with the assigned support recesses of the inner part into a disengaged or engaged position. While, for instance, the one blocking pawl is moved into the torque transmitting position, simultaneously, the other blocking pawl is moved out of the position permitting torque transmittal. This assures a short response travel and with it a rapid switchover from the one driving direction to the other without interfering with the freewheeling motion.
