Abstract

A wheel drive module (1) is provided for driving and steering a wheel (30), comprising the wheel (30), a first drive motor (11), a second drive motor (21), and a transmission. The wheel (30) can be driven and steered simultaneously by the first drive motor (11) and the second drive motor (21) via the transmission, wherein a first motor shaft (12) for driving the transmission extends from the first drive motor (11) in a first motor shaft direction (12′), a second motor shaft (22) for driving the transmission extends from the second drive motor (21) in a second motor shaft direction (22′), the first motor shaft direction (12′) and the second motor shaft direction (22′) are opposite each other, and the first drive motor (11) and the second drive motor (21) extend parallel to the first and second motor shaft directions (12′, 22′) over a common overlap section (Ü).
