The disclosure relates to a railway vehicle component group for generating an electronic life history of a machine component. The railway vehicle component group includes a machine component having a storage unit arranged in or on the machine component, and at least one control unit suitable for bidirectional communication with the machine component, wherein operating data is configured to be generated in the control unit. The storage unit is suitable at least for bidirectional communication with the control unit, wherein a storage of the operating data generated via the control unit is provided during the operation of the machine component by at least the bidirectional communication in order to generate an electronic life history of the machine component. The storage unit also has an electronic type label of the machine component. The disclosure also relates to a method for generating a life history of a machine component, as well as a service method for maintenance.

A diesel-electric drive system includes a generator having two multi-phase winding systems, a diesel engine, and a DC-link converter. Two self-commuted pulse power converters on the generator side are linked to the windings systems and to each other by a brake resistor on the alternating voltage side. The brake resistor is split into two series-connected resistors, each having half the resistance value of the brake resistor. An input of a bipolar switching device is connected to a connecting point of two series-connected resistors. The capacity of the diesel motor can then be checked in a self-load test with a controllable load torque of the diesel-electric drive system, while eliminating overloads of the power semiconductors of the self-commuted pulse power converters on the generator side.

An undercarriage () for a rail vehicle has an undercarriage frame () comprising two longitudinal supports () and at least one transverse support () connected thereto. The undercarriage has at least two wheelsets () supported in wheelset bearings (), each wheelset having a wheelset shaft () and two wheels (). The wheelset bearings () are connected to the undercarriage frame (). The undercarriage () has at least one drive () accommodated in the undercarriage frame () for driving one wheelset shaft () each. The at least one drive () is suspended in a movable fashion on the at least one transverse support (). According to the invention, the at least one transverse support () can be connected in an articulated fashion to a locomotive or railcar body () via at least one tension/pressure element () disposed in an articulated fashion on a top side (OS) and a bottom side (US) of the transverse support ().
