Abstract

An arrangement of a transmission (1) and an attachment module (4), in which the transmission (1) has a driveshaft (3) with a central, first axial bore (12) for supplying lubricating oil and the attachment module (4) has a connecting shaft (5) mounted in the housing by at least one roller bearing (6). The driveshaft (3) and the connecting shaft (5) are connected to one another, in a rotationally fixed manner, by a splined connection (8). The supply of lubricating oil for the spline connection (8) and the at least one roller bearing (6) occurs by way of the central, first axial bore (12) of the driveshaft (3).
