A drive module (1, 1a) includes an axle casing (2) and a shaft (3) rotatably mounted in an interior space (11) of the axle casing (2). Two bearing units (6, 6a) lie opposite each other and are secured in the axle casing (2) in an axial direction. Each bearing unit (6, 6a) includes an inner bearing ring (7, 7a) fixedly connected to the shaft (3), an outer bearing ring (8, 8a) fixedly connected to the axle casing (2), and rolling elements (9, 9a) arranged between the inner bearing ring (7, 7a) and the outer bearing ring (8, 8a). A lubricating fluid is present at least in the interior space (11). The lubricating fluid forming a fluid reservoir at a bottom of the interior space (11). The axle casing (2) includes a fluid opening extending, in each case, from the interior space (11) to a respective bearing unit (6, 6a) for conducting the lubricating fluid to the rolling elements (9, 9a). At least one conduction device is fluidically connected to the fluid reservoir and is configured for conducting the lubricating fluid the interior space (11) to the respective fluid opening.
