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.

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： The railborne bogie vehicle with electrohydraulic brakes and hydropneumatic leveling suspension has in each of its bogies a hydraulic pressure supply unit (9) from which pressure control valves (15, 16) parallel to each other provide pressure to both the hydraulic brakes (19) and the hydropneumatic suspension (20) of that bogie. The back pressure lines (26 and 32) of the electrohydraulic brakes (19) or of the hydropneumatic suspension (20) lead to a hydraulic tank or sump (10) associated with the pressure supply unit (9).
