Abstract
A hub drive is provided with a hub which is mounted on a hub support and with a brake device. The hub can be driven by a drive shaft with the interposition of a transmission preferably realized in the form of a planetary gear train. To be able to use the brake device of the hub drive, which has compact dimensions, both as a service brake and as a holding brake, each with good performance characteristics, the invention teaches that the brake device has a first and a second brake. The first brake is used to couple the drive shaft with the hub support with the interposition of the planetary gear train, and is used as a service brake. The second brake can be used to couple the hub and thus the web of the planetary gear train to the hub support, as a result of which it can be used as a holding brake. To save space, the first brake is located radially inside the second brake. The two brakes, which are preferably realized in the form of multi-disc brakes, have a common brake stator support, which is provided with a hollow cylindrical axial web. The brake discs of the first brake are located radially inside the axial web, and the brake discs of the second brake are located radially outside…
