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.

Crankshaft assembly with a centrifugal pendulum attached to the crankshaft

A crankshaft assembly for a motor vehicle drive train, including a crankshaft segment and a centrifugal pendulum secured thereon, 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 friction unit connected to the carrier, which rests on the at least one pendulum mass such that, with a relative movement of the pendulum mass in relation to the carrier, the friction unit applies a frictional torque on the pendulum mass counteracting the relative movement, wherein the friction unit extends over a peripheral section of less than 360°.

The disclosure relates to a crankshaft assembly for an internal combustion engine of a motor vehicle, comprising a crankshaft segment and a vibration damper accommodated on the crankshaft segment. The vibration damper has a support fastened to the crankshaft segment and a damping unit accommodated on the support. A retaining plate of the support, which plate is secured to an end face of a flange region of the crankshaft segment, has a screw receiving hole for receiving a fastening screw that connects the support to the crankshaft segment. The retaining plate also has a centering region that is offset relative to the screw receiving hole in a circumferential direction and is intended to accommodate, or so as to directly form, a centering means supporting the support relative to the crankshaft segment in a centered manner.
