Rail vehicle brake with hydraulic-mechanical brake torque control

本课题的目的是在研究自激励电液制动器（SEHB）的基础上，研究并验证一种新型液压机械铁路制动器在主动和被动工况下的制动力矩控制配置。经过实践验证的轨道车辆制动器将被修改为具有直接制动扭矩控制的系统。首先，选择合适的制动系统并对其动力学行为进行分析。在第二个工作包中，推导并系统化了液压-机械子系统，实现了典型动力和信号传输传递元件的静态和动态特性。研究结果用于主动和被动制动系统制动力矩控制结构的设计。接下来，将创建原型，并将在现有的制动试验台上进行验证。该研究是通过一辆完整的试验车的设备和随后的实际运行条件下的试验来完成的。因此，即使在不断变化的外部条件下，也可以稳健地控制所需的制动扭矩，从而使整个系统的制动性能潜力得到最佳利用。

Aim of the project is the investigation and validation of a novel configuration of hydraulic-mechanical railway brakes in active and passive type of operation with brake torque control based on the research of the Self-energizing Electro-Hydraulic brake (SEHB).Practice-proven rail vehicle brakes will be modified to systems with direct brake torque control. In a first step, suitable brake systems are selected and analyzed with regard to their dynamic behavior. In a second work package, hydraulic-mechanical subsystems are derived and systematized to realize the static and dynamic characteristics of typical transfer elements of power and signal transmission. The results are used to develop appropriate structures for brake torque control both at actively and passively operating brake systems. Next, prototypes are created and will be validated on an existing brake test rig. The research is completed by the equipment of a full test vehicle and subsequent test runs under real operating conditions. Hence, the desired brake torque can be controlled robustly even under changing external conditions and the brake performance potential of the overall system can be used optimally.
