| 摘要 |
The invention relates to a method for the driving and generative braking of a rail vehicle or a combination of rail vehicles comprising a traction drive (1), at least one permanent-field synchronous motor (6) and a traction current converter (4) being associated with at least one axle of the rail vehicle or combination of rail vehicles. The traction current converter (4) comprises at least one pulse current converter (22) on the engine side, and the clamps of the permanent-field synchronous motor (6) are connected to a switching device (30) such that the permanent-field synchronous motor (6) is connected to the traction current converter (4) in a first switching state and to a load circuit (32) containing at least one load element (28) in a second switching state. According to the invention, in order to generate a braking process with convenient functions such as anti-skid protection and/or load regulation, the permanent-field snychronous motor (6) is connected to the traction current converter (4), this first switching state being maintained until a disturbance such as insufficient braking force is detected during the braking process, and only then is the transition to the second switching state made by connection of the permanent-field synchronous motor (6) to the load circuit. |
