Covering system for wheelset shafts of rail vehicles

Abstract

A covering system for wheelset shafts of rail vehicles includes a cover, a wheelset bearing unit, and a centering device. The wheelset bearing unit has an axis of rotation, a bearing housing with an end face facing towards the cover, and a wheelset bearing for the mounting of a wheelset shaft. The wheelset bearing has an end cap surrounded by the cover. The centering device is for aligning the cover in relation to the bearing housing. The centering device includes a groove on the end face.
