Abstract
A bogie for a rail vehicle, such as a locomotive, includes a frame, two wheelsets and at least one drive unit. The drive unit is mounted to the frame and to the wheelset. A motor is at least partially supported by the frame while a gearbox to which it is flexibly connected has a main gear mounted on the one wheelset as well as a pinion for driving the main gear. The gearbox is connected to the frame by a reaction rod placed away from the wheel-axle on which the gearbox is mounted. The reaction rod, which defines an axis, is aligned so that its axis extends substantially through a center of the bogie when projected in a longitudinal-vertical plane bisecting the bogie.
