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 ( ) which is mounted fixed in terms of rotation to the vehicle frame ( ) and which is rotatably connected as a wheel hub to a ring gear ( ) via a roller bearing arrangement ( ), the ring gear ( ) being driven via at least one planetary gear mechanism ( ) with drive-end sun wheel ( ), and an integrated dynamic service brake ( ) being provided between the ring gear ( ) and the carrying axle ( ), it is proposed that the service brake ( ) be arranged within the ring gear ( ) at the end directly behind a detachable gear mechanism cover ( ) and at the outer radius on a hollow-cylinder-shaped brake carrier ( ) which forms the end piece of the carrying axle ( ) which is fixed in terms of rotation, and that the planetary gear mechanism ( ) be arranged behind the service brake ( ), viewed from the end, within the ring gear ( ).

A mounting sleeve extends from a vehicle body or other housing and contains on its body/housing side a planetary gearing whereby, in particular, the sleeve is provided with an internal ring gear for planetary gearing; the sun gear is carried by an input shaft, and the planet gear carrier is integral with a shaft which is keyed to a hub; the hub is journaled by two roller bearings in the mounting sleeve both being on the same side, as far as the planetary gearing is concerned. The roller bearing elements are of a frustoconical configuration, and their axes are particularly oriented to prevent the reaction of radial and axial forces into the gearing.
