A device for controlling a rail vehicle wheel slip and a method of controlling wheel slip of a rail vehicle in this device

摘要

The wheel slide control device with a torque modification block (1) has a first input (1.1) for input (T) input, a second input (1.2) connected to the output (7.2) of the controller block (7) and a third input (1.3) ) coupled to the first output (5.1) of the excitation signal source block (5). The excitation source block (5) comprises a first generator for generating a periodic excitation signal (ΔT), the output of which is coupled to the first excitation source output (5.1). The torque modification block (1) is connected with its output (1.4) to the input (2.1) of the electric drive block (2), the first output (2.2) of which is connected to the input (3.1) of the mechanical drive block (3). comprising an encoder for measuring the angular rotational speed (ω) of the traction motor, the output of which is coupled to the output (3.2) of the drive mechanical block (3) connected to the input (4.1) of the desired adhesion limit slope (4) at the operating point. Also included is a block (6) for estimating the slope of the adhesive characteristic at the operating point, the output of which (6.4) is connected to the positive input of the reading block, to the negative input of which the output (4.2) of the block (4) . The output of the reading block is connected to the input (7.1) of the controller block (7), whose output (7.2) is connected to the second input (1.2) of the torque modification block (1). A method for controlling the slip of wheels of a rail vehicle in this device is also proposed.
