Torque limiter with a rotational axis for a drive train

A torque limiter for a drive train includes a rotational axis, a first cover disc and a second cover disc, a central disc arranged axially between the cover discs, a first friction lining and a second friction lining, a radially outer connector and a radially inner connector, and a spring element. The first friction lining is for frictionally locking torque transmission between the first cover disc and the central disc, and the second friction lining is for frictionally locking torque transmission between the second cover disc and the central disc. The radially outer connector is permanently connected to the cover discs in a torque-transmitting manner, and the radially inner connector is permanently connected to the central disc in a torque-transmitting manner. The spring element is arranged between the central disc and the first friction lining or the second friction lining.

SPRING ELEMENT FOR A FRICTION DEVICE

The invention relates to a spring element (4) for a friction device comprising a spring element body (10) having a first spring element body part (11) and a second spring element body part (12) arranged behind it in the axial direction, which rest on each other in some areas, and each spring element body part (11, 12) has receiving areas (15) arranged beside one another in a circumferential direction (13) for friction linings (2, 3) that can be fixed to both sides, and the first spring element body part (11) and the second spring element body part (12) are formed in a ring shape and a first and second receiving tab (19, 20) are formed for each receiving area (15) for the friction linings (2, 3), and the first receiving tab (19) is arranged underneath the second receiving tab (20) in the radial direction, and the first receiving tab (19) and the second receiving tab (20) of each receiving area (15) for the friction linings (2, 3) of the first spring element body part (11) are formed by the latter and the first receiving tab (19) and the second receiving tab (20) of each receiving area (15) for the friction linings (2, 3) of the second spring element body part (12) are formed by the latter.
