Abstract

The invention relates to a traction drive (1) for the driving and generative braking of a rail vehicle or a combination of rail vehicles, 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 change-over switch (30) such that the permanent-field synchronous motor (6) can be connected to a load circuit (32) forming a load, in order to drive the pulse current converter (22) or for generative braking. According to the invention, the load circuit (32) connected to the permanent-field synchronous motor (6) for generative braking is designed and/or controlled in such a way that the characteristic values of the load circuit (32) can be modified according to the loading of the rail vehicle or combination of rail vehicles.

Description

Background technique [0001] The present invention starts from such prior art: [0002] Traction drive systems for drive and regenerative braking (regenerative braking) of rail vehicles or rail trains, in which at least one axle of a rail vehicle or rail train is equipped with at least one permanently excited synchronous motor and a traction converter, and the traction converter has at least one pulse converter on the motor side, the permanent magnet excitation synchronous motor is connected to a changeover switch at its terminals in such a way that the permanent magnet excitation synchronous motor the pulse converter can be switched on for driving, or the load line constituting the load can be switched on for dynamic braking, as described in the preamble of claim 1, and [0003] · Devices for load compensation during dynamic braking of a rail vehicle or rail train comprising an air damper with at least one air spring box, as claimed in the right Requirement 9 described in th...
