1. A wheel drive module (1) comprising a wheel (30) and a transmission, wherein
the transmission comprises a first and a second drive gear ring (15, 25), which are arranged such that they can rotate about a common rotation axis (R),
the wheel (30) can be steered and driven by a respective rotation of the first drive gear ring (15) and the second drive gear ring (25), and
a wheel-receiving space (20) extending along the axis of rotation (R) is defined between the first drive gear ring (15) and the second drive gear ring (25), in which the wheel (30) is arranged at least sectionally, and
wherein the wheel drive module comprises
an output shaft (31) connected to the wheel (30), with a driven gearwheel (32), which can be rotated about a wheel axis (A) extending orthogonally to the rotation axis (R) and which can be driven by the first and the second drive gear rings (15, 25), and
an intermediate shaft (34) which extends along an intermediate axis (Z) different from the wheel axis (A), a driving intermediate wheel (33) and a driven intermediate wheel (35), which are arranged along the intermediate axis (Z) of mutually opposite sides of the intermediate shaft (34) and are connected to the intermediate shaft (34), wherein the driving intermediate wheel (33) engages in the first and second drive gear rings (15, 25), and the driven intermediate wheel (35) engages in the driven gearwheel (32) and can be driven via the intermediate axis (34) of the wheel (30) about the wheel axis (A).
