Abstract
A transmission arrangement for a vehicle drive train includes a planetary wheel set with a planetary carrier with at least one bolt. A first bearing element on the bolt is arranged for rotatably mounting a planetary wheel. The transmission arrangement also has a differential connected to the planetary carrier in a drive-effective manner and configured to transfer a drive power acting on the planetary carrier to a first center shaft and to a second center shaft arranged coaxially thereto, where at least the first center shaft defines a central first channel for the cooling and/or lubricant supply to an interior of the differential, and defining at least one first bore hole on the planetary carrier which extends radially at least in some sections and is configured to guide the coolant and/or lubricant out of the interior of the differential into a second channel of the bolt.
