Abstract
The invention relates to a lamellar clutch (100) with several lamellae (115, 116) arranged alternately on the input and output sides around a rotational axis (d), forming a lamellar pack (114), wherein the lamellar pack (114) can be biased at an end lamella (101) by axial fingers (103) of an actuating element arranged around the circumference against a stop arranged on the opposite side of the lamellar pack (114). In order to achieve a uniform pressure on the end lamella (101) with a small number of fingers (103) or to be able to reduce the thickness of the end lamella (101), force transmission elements are provided between the individual fingers (103) and the end lamella (101) with a single force absorption point (405) connected to the fingers (103) and with a plurality of circumferentially spaced force introduction points (406) opposite the end lamella (101).
