摘要：: A wheel hub transmission unit for a drive wheel of a vehicle is provided. The wheel hub transmission unit includes a wheel axle, a pinion hub carrier concentrically arranged with respect to the wheel axle, a pinion mounted in a torsionally rigid manner onto said pinion hub carrier and configured to drive the drive wheel, and a torque transmission device having a transmission sleeve. The transmission sleeve is made from a magnetically coded material and includes a measuring area that is utilized to measure a torque by utilizing magnetic properties of the magnetically coded material of the transmission sleeve. An annular space is radially provided between the transmission sleeve and the wheel axle in the measuring area with a sensor coil being accommodated therein, the annular space being axially accessible from outside the transmission sleeve.
