摘要： A method for influencing the kinematic behavior of a vehicle, in particular a rail vehicle with at least one friction brake system, wherein a brake effect is generated by pressing at least one first and second friction elements against each other, where to achieve advantageous method conditions, temperatures of at least the first friction element are calculated from at least speed, brake pressure, external temperature of the vehicle and absolute times, and heat conduction through the first friction element and a speed-dependent cooling process of the first friction element are taken into consideration during the calculation, and where the kinematic behavior of the vehicle is influenced based on the calculation such that expensive fitting of the friction brake system with sensors for measuring friction element temperatures can be advantageously omitted, and the thermal state of the friction brake system can still be estimated with a high degree of precision.

摘要： A device for securing braking devices to a chassis frame of a rail vehicle forming a cross-member of the chassis frame that has a longitudinal axis, and includes at least two securing points for braking devices, wherein the securing points are spaced apart from the cross-member in a longitudinal direction which lies normal to the longitudinal axis, where at least one respective securing point is arranged at the end on a continuous brake carrier having an open cross section, where a connector is provided, via which the brake carrier is both connected to the cross-member and is spaced apart from the cross-member in a vertical direction to reduce the weight and so as not to simultaneously increase the warp stiffness of the chassis frame.

摘要： A device and method for forecasting the brake lining wear, in particular the brake lining of rail vehicles, wherein the lining thicknesses, the sliding speed, the contact pressure, the total braking time, as well as optionally the temperature or the brake power are determined in a parameterization process during test drives with measurements at predefined time intervals, and the wear, the constant, as well as the material parameters are determined therefrom, where during the operating state, the wear rates are determined via the now known values of the material parameters and of the constants, and the wear is determined therefrom and, from the maximum allowable wear values, a remaining total braking time is then determined until the next lining replacement is required.

摘要： A device transmits a force between a chassis and a body of a rail vehicle. The device is a structurally simple, space-saving device which allows spring movements and rotational movements of the body relative to the chassis. This is achieved in that at least one first traction link buffer, which has a first end face, and at least one second traction link buffer, which has a second end face, are fixed to the chassis. The first end face is spaced from the second end face in a longitudinal direction of the rail vehicle. The two end faces point in at least approximately opposite directions, and a stop plate with sliding portions which are mutually spaced in the longitudinal direction is provided on the body. The end faces of the traction link buffers rest against the sliding portions in a slidable manner at least along some sections.

摘要： Absorption spectrometer and method for measuring the concentration of a gaseous component of interest in a measurement gas, wherein to compensate influence of changes in an optical path length in the absorption spectrometer on a measured result, light from the laser is modulated with at least one pilot frequency in the MHz range, the measurement signal is analyzed in a phase-sensitive manner for the pilot frequency, phase information obtained during this analysis is compared with phase information obtained during calibration of the absorption spectrometer, where the measured result is corrected as a function of the difference between the two items of phase information. Alternatively, light from the laser is modulated with two pilot frequencies, where signal components contained in the measurement signal with the pilot frequencies are detected in a phase-sensitive manner and the difference between the phase information of the two signal components obtained in this operation is analyzed.
