  • Patent number: 5671682
    Abstract: The invention relates to a sway brace on rail vehicles. The aim of the invention is to find a solution in which the effort and expense needed to produce the sprung sway braces can be reduced and the transverse forces and the resultant wear occurring on deflection can be reduced to the minimum. This is achieved by the invention in that one end of the sprung sway braces in a special design is arranged in a support with defined guide surfaces while the other end is secured to the piston of a hydraulic cylinder via an axial rocker beating. In addition, there is a disc spring column above the sway brace.

  • Patent number: 5405182
    Abstract: The electronic brake control simulates by electronic means various real changes over time of the pneumatic pressures in a braking system, in particular the pressure in the main air pipe of the train, the pressure in the R containers of the individual wagons and the pressure in the individual brake cylinders. When the brakes are released, the values are determined from these model values and the actually backfed air volume, from which values the pilot control pressure for a relay valve can be increased in order to release the brakes more rapidly. The train model determines, by an adaptive learning method at the end of a brake releasing process, values for the volume of the main air pipe and the R containers of the train, so that the train model adapts itself to the actually existing train.

  • Patent number: 5328253
    Abstract: The electropneumatic control system for the pressure in the main air pipe (37) of compressed air brakes of rail cars is provided with one inlet and one outlet solenoid valve (3 and 4) to control the pressure in a control chamber (26) of a relay valve (19). The inlet solenoid valve (3) and the relay valve (19) are supplied with compressed air from a main reservoir pipe (34). The relay valve controlled by the pressure in the control chamber (26) against the pressure in the main air pipe (37) controls the compressed air lead-in and lead-out for the main air pipe (37). To avoid the undesired response of the relay valve (19) to pressure changes elsewhere in the main air pipe (37), the two sides of the piston (20) of the relay valve (19) are closed without any throttling by way of the secondary valve parts (13 or 14) of the two solenoid valves (3 and 4) in the unactuated state of the control system (2).

  • Patent number: 5147114
    Abstract: 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.

  • Patent number: 5090519
    Abstract: In a disk brake actuated preferably hydraulically, a piston (5) is guided within a housing located in a caliper. When pressure is applied, the piston acts in such a manner against a brake shoe (15) bearing a brake lining (17) that the brake shoe (15) is pressed with its brake lining against the brake disk to be braked. The side of the piston facing the brake shoe has a pressure plate (13) which transmits the pressure forces and which moves transversely within its recess in the piston (5). The pressure plate (13) is mounted on the end of a tappet (25) extending axially inside the piston (5) and bracing itself at the end opposite the pressure plate by a disk (27) at the bottom (29) of the bore (31) accommodating the tappet, and is surrounded by a prestressed compression spring (37). Lateral movements of the pressure plate (13) cause tipping of the tappet (25) and, as a consequence thereof, a reset force exerted by the compression spring (37 ) on the tappet (25) and, thus, on the pressure plate (13).
