1. A crankshaft assembly for a motor vehicle drive train, comprising:
a crankshaft segment; and
a centrifugal pendulum secured to the crankshaft segment, the centrifugal pendulum including a carrier secured to the crankshaft segment and at least one pendulum mass that moves relative to the carrier along a predetermined track, the crankshaft assembly having a rupture containment means, which engages radially externally around the centrifugal pendulum such that components of the centrifugal pendulum coming lose during rotation of the centrifugal pendulum are collected by the rupture containment means,
wherein the crankshaft assembly has a friction device which is connected to the carrier and which rests against the at least one pendulum mass in such a way that the friction device applies to the pendulum mass a frictional moment counteracting a relative movement when the pendulum mass moves relative to the carrier,
wherein the friction device has a friction element resting against the pendulum mass, a receiving disc connected to the carrier and a spring element supported axially between the friction element and the receiving disc, wherein the receiving disc forms the rupture containment means,
wherein the friction element is received in the receiving disc in a non-rotatable manner on a radial outer side of the friction element.
