A railway self-generating express freight car bogie has a wheel-axle assembly, frame, journal box suspension device, bolster, foundation brake, side bearing, empty/load auto-adjustment equipment, central suspension device, longitudinal traction device, vertical damper and lateral damper. An axle-end generator is connected at the outer end of an axle of the wheel-axle assembly, the rotor part of the axle-end generator is connected to the end bearing of the wheel-axle assembly by the axle-end bolts, and the stator part is connected to the mount of the journal box suspension devices. The bogie is designed according to the zero-wear concept, and a large number of rubber components and hydraulic dampers are used to improve the lateral stability, linear stability and curve passing performance of the car, so that the bogie is highly adaptable to railway lines, and can meet the operating requirements within 160 km/h and reduce the workload of bogie operation and maintenance.

A drive system for a rail vehicle includes at least one drive motor and at least one cooling apparatus for cooling the at least one drive motor and/or other components of the drive system, in particular a current converter. The drive system is constructed and intended to use kinetic energy of the rail vehicle for operation of the cooling apparatus. A rail vehicle having the drive system and methods for the forward movement of a rail vehicle are also provided.

A wheelset bearing for a rail vehicle has a generator which is designed as a claw-pole generator, which includes at least one non-rotating claw ring, as well as a sensor system supplied with electrical energy by the generator The sensor system has a plurality of sensor system modules which are at least partially fastened to a sensor carrier placed on the claw ring and which are connected to a common data line.
