A hydrostatic hub drive with an integrated axial piston machine utilizing a swashplate design, in particular a wheel hub drive, has a stationary hub carrier in the form of a machine housing of the axial piston machine, a hub formed by a machine shaft and mounted inside the hub carrier so that it can rotate, and a hub bearing in the form of a shaft bearing. The axial piston machine is configured as an individual drive unit and has an individual cylinder block on the machine shaft that extends out of the machine housing through an outlet opening. A swashplate is located in an area near the outlet opening and a control base receptacle is located in an area farther from the outlet opening. The axial piston motor is preferably a fixed displacement motor and has a swashplate that is shaped into the machine housing, which swashplate is oriented so that the radial components of the propulsion forces, under operating conditions, are effectively directed opposite to the external forces acting on the hub bearing system. A brake in the form of a wet-running, spring-loaded, multiple-disc brake can be located radially between the cylinder block and the machine housing. It is also possible to locate the brake in a recess of the cover. Shaped onto the machine shaft is a wheel flange that can hold at least one wheel rim, which wheel flange as a rim centering device and concentric threaded borings.
