摘要： The electrohydraulic directional control valve system includes a preliminary directional control valve and a main control valve, the latter having a control spool which is normally brought into its neutral or blocking position by means of two springs arranged in pressure chambers at respective ends of the control spool. The preliminary control valve has a sliding spool which at one end is urged by a spring into an additional safety position in which the pressure chambers of the main control valve are interconnected and pressure relieved, and the intake of the pressure fluid is blocked. A single proportionally operating solenoid counteracts the spring at the other end of the control spool of the preliminary control valve.

摘要： The present invention is a process and system for controlling the wagon body of a vehicle which can be used alone or in combination with a steel spring system. The control system has comparatively small geometrical dimensions and requires relatively little energy and includes a pressure accumulator connected in parallel to delivery pump 8 of the hydraulic pressure medium. The two devices working together against the pressure of the hydropneumatic pressure accumulator of the body height system. Thus, the pressure accumulator can be charged during the travel of the vehicle so that the pump does not have to be designed according to the peak load in the case of a fast load change.

摘要： The electrically controllable pressure medium brake comprises an electric pressure means (EP) converter (1) to convert an electrical brake request signal into a brake pressure. By way of an emergency brake valve (1), this brake pressure (in the normal case) and a vehicle load-dependent emergency brake pressure limited by a limiting valve (12) (in an emergency), is fed to the brake cylinder (14). For vehicle load-dependent limitation of the emergency brake pressure, a second EP converter (1a) generates from a vehicle load-dependent, electrical signal a vehicle load-dependent pressure medium pressure, which is stored in a pressure medium reservoir (18) and is fed to the limiting valve (12) in order to control it. The second EP converter (1a) is closed in the currentless state, during a power failure, whereby the vehicle load-dependent pressure medium pressure is preserved and the limiting valve (12) can thus continue to limit the emergency brake pressure as a function of the vehicle load. In another embodiment supplemented by a switching valve, only one EP converter serves to generate both the brake pressure and the vehicle load-dependent pressure medium pressure.

摘要： A secondary suspension for a rail vehicle includes a superstructure, a bogie and a steel spring arranged between the superstructure and the bogie. The steel spring ensures at least one raised traveling level for the superstructure when the rail vehicle is traveling. Further included is a tension cylinder. When the rail vehicle is stopped, the steel spring is compressed by the tension cylinder to adjust the superstructure to a lowered station platform level below the at least one traveling level.

摘要： The electrically controllable brake, preferably pressure actuated brake for vehicles has a control device (13) which, controlled by a brake demand signal, monitors the release of an appropriate braking power or a corresponding braking pressure. For the vehicle load dependent limitation of the braking force or the braking pressure, a vehicle load signal, present as electrical signal value, is led to a modem (38 to 45), which converts the electrical signal value into a mechanical signal value (prestress of the control spring 36). The mechanical signal value directly controls a limiting device (pressure limiting valve 11) which serves for the vehicle load dependent limitation of the braking power or the braking pressure to be delivered. During a failure of the electrical vehicle load signal, of the electric components and/or of the power supply, the modem maintains approximately constant the momentary mechanical signal value, so that the braking power or braking pressure to be delivered remains limited in dependence on the vehicle load, even during a failure of the vehicle load signal. This prevents overbraking of the vehicle during the stated and other emergencies.

摘要： Hydraulic vehicle brake comprising a hydraulic accumulator (1), a brake valve adjustment device (4) supplied thereby, and a brake pressure line section (7) to the brake cylinders attached to the latter via an emergency brake valve (6). In the emergency braking position of the emergency brake valve, this connection is broken, and the brake pressure line section is directly connected to the hydraulic accumulator via a nozzle (10) which is bridged by a cylinder (13) in which a piston is sealingly displaceable. A spring (17) biases the piston in the displacement direction to the accumulator side end connection (11) of the cylinder. During emergency braking, the piston (14) first forces an amount of hydraulic medium sufficient for brake application out of the brake cylinder side chamber (16) of the cylinder (13). This is followed by a damped increase in brake pressure through additional supply of hydraulic medium from the hydraulic accumulator (1) through the nozzle (10) into the brake cylinders. The brake assures rapid brake application during emergency braking, with subsequent damped brake pressure increase, so that shocks and jolts resulting from emergency braking are kept within acceptable limits.
