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

摘要

The wheel slide control device with a torque modification block (1) has a first input (1.1) for the supply of the input parameter (TR), 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 signal source block (5) comprises a first generator for generating a periodic excitation signal (ΔTER) the output of which is coupled to the first excitation signal source output (5.1). The torque modification block (1) is connected by 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) containing 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 mechanical drive 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 adhesiveness at the operating point, the output of which (6.4) is connected to the positive input of the reading block, whose negative is connected to the output (4.2) of the desired marginal declination of the adhesion characteristics in the working point. The output of the reading block is connected to the input (7.1) of the controller block (7), the output of which(7.2) is connected to the second input (1.2) of the torque modification block (1). A method for controlling a rail vehicle wheel slip in this device is also proposed.
