ABSTRACT:
A torque limiting coupling (5) has a plurality of slide-like driving members (19) circumferentially and movably distributed in a coupling hub (10). The unit is rotatably accommodated in a coupling sleeve (7). The driving members (19), with their torque transmitting faces (25) at their heads, are pushed by a spring assembly (38, 39) and switching cams (32) into correspondingly designed recesses (22) of the coupling sleeve (7). The pressure springs (38, 39) and the switching faces (30, 31) of the driving members (19) as well as the torque transmitting face (25) are arranged so as to extend in the same direction. Thus, the springs (38, 39), during the transmission of torque by the coupling sleeve (7), subject the driving members (19) to a moment which acts against the tilting moment resulting from the transmission of torque. This results in an improved wear and switching behavior.
