The disclosure relates to a belt pulley decoupler for a motor vehicle drive train that includes a hub constituent part configured for attachment to a crankshaft of an internal combustion engine, a flexible drive element pulley supported in a spring-damped manner relative to the hub constituent part, and a vibration absorber. The vibration absorber includes a mounting plate that extends from a fastening region, which is supported on the hub constituent part and connected to the hub constituent part in a positively locking and/or non-positive manner, radially outwards to a collar region which receives at least one mass element. The fastening region has a plate portion which is supported axially on a flange element of the hub constituent part and which is held relative to the hub constituent part via an axially running dome portion formed either by the mounting plate or the flange element.

A crankshaft assembly for a motor vehicle drive train includes a crankshaft segment and a centrifugal pendulum secured to same, which has 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 has 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.
