Abstract: A forged wheel for a chassis of a rail vehicle includes a wheel web, a wheel hub and a wheel rim with a running surface and a wheel flange, where material is recessed out of the wheel web, which is solid in sections, between the wheel hub and the wheel rim, in sections extending in the circumferential direction or transversely with respect to a radial direction of the wheel web, and where at least a first distance and a second distance between a recess centre point of a first recess in the wheel web and an edge of the first recess differ in size such that a lightweight wheel that can be manufactured with little outlay and that has high strength and quality is obtained.

Abstract: A chassis for a rail vehicle includes at least one chassis frame to which at least one first wheel set and a second wheel set are coupled and to which at least one first drive unit and a second drive unit are connected, wherein a first coupling rod is connected at least to the first drive unit in an articulated manner and is configured to be coupleable to the vehicle body of the rail vehicle in an elastic manner, such that advantageous structural conditions are achieved.

Abstract: A wheel set for a rail vehicle, in particular for a locomotive, includes two track wheels which are connected by a wheel axle mounted in two wheel set bearings. Each wheel set bearing includes a cast bearing housing, which is closed by an outer housing cover and an inner pressure ring. In addition, the bearing housing has a clamping position for engaging a tensioning device of a machine tool for machining the wheel set. Since the clamping position is integrated in the pressure ring, the clamping position can be easily cut to size and the bearing housing can be produced in a weight-optimized and cost-effective way in comparison to known bearing housings.

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.
