Abstract
A bogie for locomotives is provided. Two wheelsets, each including a drive unit, are disposed in a bogie frame, wherein the wheelsets each include a wheelset shaft and two wheels. The drive unit comprises a motor unit and a transmission disposed to ride on an axle, and each motor unit is suspended at three points, namely at a main pivot point on the transverse beam of the bogie frame and two mounting points on a head beam of the bogie frame. Further, the motor unit is transversally elastically suspended; the transmission is mounted pivotally about the wheelset shaft but not displaceable along the wheelset shaft. The transmission is further connected to the motor unit by a transmission torque support, and the drive unit comprises a clutch by which the motor unit has a driving connection to the wheelset by the transmission.
