1. A differential assembly comprising:
a differential housing supporting at least a first shaft having a first gearwheel, the differential housing designed to be connected to a lubricant supply;
a rolling bearing for mounting the first shaft;
a cover fixed to the differential housing and fixing the rolling bearing to the differential housing;
a circumferential first lubricant channel formed in the differential housing between the first gearwheel and the rolling bearing on a first side of the rolling bearing;
a circumferential second lubricant channel formed between the cover and the rolling bearing on a second side of the rolling bearing; and
an inner third lubricant channel formed in the differential housing and extending from the second lubricant channel within a wall of the differential housing as far as an inner side of the differential housing;
wherein lubricant flows from the first lubricant channel in a first direction away from the interior of the differential housing through the rolling bearing into the second lubricant channel and then in a different second direction through the third lubricant channel and into the interior of the differential housing.
