Abstract
In order to achieve a repair-friendly and maintenance-friendly arrangement with improved conduction away of heat to the outside in a wheel drive, in particular for mobile machines, having a carrying axle (2) which is mounted fixed in terms of rotation to the vehicle frame (1) and which is rotatably connected as a wheel hub to a ring gear (4) via a roller bearing arrangement (3a, 3b), the ring gear (4) being driven via at least one planetary gear mechanism (24) with drive-end sun wheel (16), and an integrated dynamic service brake (24) being provided between the ring gear (4) and the carrying axle (2), it is proposed that the service brake (24) be arranged within the ring gear (4) at the end directly behind a detachable gear mechanism cover (11) and at the outer radius on a hollow-cylinder-shaped brake carrier (10) which forms the end piece of the carrying axle (2) which is fixed in terms of rotation, and that the planetary gear mechanism (34) be arranged behind the service brake (24), viewed from the end, within the ring gear (4).
