Abstract (en)
[origin: WO2022216569A1] A rotor (46) is rotationally received in an operational cavity defined by a housing (12) including an output flange (34) and allows flexible movement of a friction facing (50). The friction facing (50) is intermediate an actuation plate (60) and output flange (34). Cylindrical cavities (30) in the housing (12) receive springs (86) biasing the actuation plate (60) towards the friction facing (50). An annular cavity (26) in the housing (12) receives an electromagnet (90) drawing the actuation plate (60) towards and against the bias of the springs (86). A flexible plate (70) moveably connects the actuation plate (60) to the housing (12). First fasteners (76) extending into the annular cavity (26) and through the flexible plate (70) and into the actuation plate (60). Second fasteners (80) extending through bores (62) extending through the actuation plate (60) and extending through the flexible plate (70) and into the housing (12).
