The invention relates to a wheel hub transmission unit for a drive wheel (1) of a vehicle having a wheel axle (2), a pinion hub carrier (7), which is arranged concentrically to the wheel axle (2) and on which at least one pinion can be installed in a rotationally rigid manner in order to drive the drive wheel (1), and a torque-transmitting device (9), which is arranged radially between the pinion hub carrier (7) and the wheel axle (2) and which has a transmission sleeve (10), which is arranged concentrically to the wheel axle (2) and is made of a magnetically coded material and has a first longitudinal end (11), on which an input coupling (13) is provided, by means of which the first longitudinal end (11) and the pinion hub carrier (7) are coupled to each other in a rotationally rigid manner, and a second longitudinal end (12), which faces away from the first longitudinal end (11) and is arranged at an axial distance from the first longitudinal end and on which an output coupling (17) is provided, by means of which a torque can be transmitted to the drive wheel from the transmission sleeve (10), such that a measurement region (20) of the transmission sleeve (10) for measuring the torque is formed axially between the couplings (13, 17), wherein the transmission sleeve (10) is born on the wheel axle (2) in the axial extension region of the input coupling (13) by means of a radial bearing (21) in a floating manner at the first longitudinal end of the transmission sleeve and is supported at a radial distance from the wheel axle (2). |
