The invention relates to a support arrangement for a divided articulated shaft in a vehicle comprising at least one driving axle (2) and at least one non-driving supporting axle (1), in which arrangement the articulated shaft (11) passes through the non-driving axle (1) and is supported near it to substantially follow the vertical movements of the non-driving axle (1), this axle being in turn supported from its middle to the frame (5) of the vehicle by means of an axle supporting unit (4). In order to avoid the lateral shifts and torsions of the articulated shaft (11), the shaft is supported onto said supporting unit (4) in the middle of the axle.
