A centrifugal pendulum for damping rotational irregularities of a driveshaft of an internal combustion engine, having a carrier flange element connectable indirectly or directly to the driveshaft, and having multiple pendulum elements displaceable in relation to the carrier flange element, and guided via rollers in pendulum paths. Each pendulum element is displaceable in relation to the carrier flange element in the circumferential direction between a first and a second stop position. At least one friction element having defined thermal expansion properties, which are different in particular from the carrier flange element and/or the pendulum elements, is associated with the carrier flange element, and is designed and arranged in such a way that in a defined temperature range of the centrifugal pendulum, upon a movement of at least one pendulum element corresponding to the friction element in the direction of a stop position.

A torque transmission arrangement in a motor vehicle drive train, having a radially inner shaft and a radially outer hub, which are joined together in torque-transmitting manner by a plug-in toothed gearing with play, in which the plug-in gearing, and shaft outer teeth cooperate with hub inner teeth. In order to avoid gear teeth clattering, and to provide a freedom from play in the plug-in gearing, a spring element is provided, with which the shaft and can be braced against each other. In order to produce the freedom from play, the hub includes a support portion against which the spring element is supported with a spring force, building up a tilting moment by which the hub can tilt with respect to the shaft in the axial direction.
