Abstract
A bogie with three wheel sets for a rail vehicle is described, in which the bogie has two end wheel sets (3) which are connected to a bogie frame (2) at their drive units by in each case at least one slanted link (1), and a center wheel set (12) is connected to the bogie frame by at least one longitudinal link (4) guided parallel to the longitudinal direction of the bogie frame (2). The end wheel sets (3), by in each case at least one transverse link (5a, b) and by a drive-unit extension arm (13) arranged in operative connection with the transverse link (5a, b), are connected to the drive unit of the center wheel set (12) in such a way that, during a transverse movement of the center wheel set (12), the end wheel sets (3) are coupled with the latter and that, during a turn-out movement of the end wheel sets (3), the latter are coupled in opposite directions. Furthermore, the drive units in each case have at least one brake device (8), each of these brake devices (8) being arranged directly on the motor (6) or on the gear case (11) and acting on at least one wheel disc (10) of the associated wheel set (3, 12).
