TRACTION DRIVE OF A RAIL VEHICLE FOR DRIVING AND GENERATIVE BRAKING WITH LOAD CORRECTION
First Claim
1. A traction drive for driving and for performing regenerative braking of a rail vehicle or of a combination of rail vehicles, the traction drive comprising:
- at least one permanently excited synchronous motor and one traction current converter assigned to at least one axle of the rail vehicle or of the combination of rail vehicles wherein the traction current converter has at least one machine-side pulse current converter and the permanently excited synchronous motor is connected at its terminals toa changeover switch connected to the terminals of the permanently excited synchronous motor in such a way that the permanently excited synchronous motor is selectively connected to the pulse current converter to perform driving or to a load circuit containing a load to perform regenerative braking,wherein the load circuit connected to the permanently excited synchronous motor to perform regenerative braking is configured in such a way that the characteristic variables of the load circuit can be changed as a function of the loading of the rail vehicle or of the combination of rail vehicles.

Abstract
The invention relates to a traction drive for the driving and generative braking of a rail vehicle or a combination of rail vehicles, at least one permanent-field synchronous motor and a traction current converter being associated with at least one axle of the rail vehicle or combination of rail vehicles. The traction current converter includes at least one pulse current converter on the engine side, and the clamps of the permanent-field synchronous motor are connected to a change-over switch such that the permanent-field synchronous motor can be connected to a load circuit forming a load, to drive the pulse current converter or for generative braking. According to the invention, the load circuit connected to the permanent-field synchronous motor for generative braking is designed and/or controlled in such a way that the characteristic values of the load circuit can be modified according to the loading of the rail vehicle or combination of rail vehicles.
