Abstract: A spring brake cylinder having an emergency release device, particularly for rail vehicles, comprising: a housing; a spring piston for operating and releasing a spring brake; a normally locked, not self-locking threaded screw drive; an outer-radial sliding surface having a detent flank, the outer-radial sliding surface being an element of a rotatable part of the threaded screw drive, and the threaded screw drive having a pitch dimensioned such that the rotatable part carries out less than a complete rotation along its maximal axial adjusting stroke, and the detent flank being configured for locking the emergency release device; and a latch for interacting in a form-locking manner with the detent flank to lock the emergency release device, and for releasing the spring brake in the absence of a release pressure medium and thereby permitting axial movement of the spring piston.

Abstract: The invention relates to a brake system (100) for a railway vehicle (1). Said brake system comprises a main air reservoir line which is fed by an air compressor unit (22). Every bogie truck (3) is provided with at least one compressed-air line which is connected to the main air reservoir line either directly or via a stop valve, a non-return valve and a compressed-air reservoir. The compressed-air line feeds, for example, the service brake valves for impinging the brakes of the bogie truck (3) or a control unit for the spring-loaded brake and/or other control units for other auxiliary components. The service brake valves and/or the spring-loaded brake and/or other auxiliary components are controlled via at least one local, electronic brake control unit (31).

Abstract: The invention relates to a sintered material as friction material for a pole shoe, a pole shoe area or at least an area of the pole shoe friction surface of a magnetic track brake (300), more particularly an eddy current brake and/or magnetic track brake with a magnetic basic and/or carrier member.

Abstract: The present invention relates to a brake pad for rail vehicles, including at least two friction material blocks and at least one holding device. The individual friction material blocks are lamellar in shape and are connected to one another along their longitudinal sides to form a brake pad. The connection is constructed such that the individual friction material blocks may be displaced with respect to one another. The present invention also relates to a rail vehicle brake including at least one brake shoe, a friction material block holding device, a power unit having a carrier body and a connection device connecting the power unit to the at least one brake shoe.

Abstract: A device for the vibration-absorbing mounting of a compressed-air generator including a first spring element which is mounted on a mounting support. A second spring element is provided on which the compressed-air generator is arranged. One of the two spring elements has a spring rigidity in essentially the vertical direction that is maximally half its spring rigidity in essentially the horizontal direction. The second spring element is arranged in series with the first-spring element. The inventive device reduces the acceleration measured at the bottom of the understructure to values which are at least 30% of the values known from the prior art.

Abstract: A device for supplying current and/or voltage to a vehicle trailer for the electric supply of brake components of the vehicle trailer, where the vehicle trailer is connected with the tractor vehicle by a first supply line. At least one second supply line is provided to connect the vehicle trailer with the tractor vehicle. A brake light supply line may be used as the second supply line providing the current and/or voltage supply line for the electronic and/or electric components of a braking device of a vehicle trailer when the supply of the braking device has failed.

Abstract: The invention relates to a braking body for a rail car, especially a brake block or disk brake pad, comprising a supporting body with recesses and friction material elements arranged in the recesses. The friction material elements form a friction surface with the supporting body and are mounted with elastic or tilting elements such that the frictional material elements can move in the longitudinal direction of the recesses and adapt themselves to the running surface of a rail wheel.

Abstract: A sintered material is used as a friction material for a pole shoe area of a magnetic track brake, having at least one of a magnetic basic member and a carrier member. The sintered material contains at least one of a proportion of pulverized wear inhibitor and a proportion of powder forming a protective layer.

Abstract: The invention relates to a brake lining mounting, especially for rail vehicles, comprising a lining support which is encompassed at both of its longitudinal ends by guide sections, preferably at least partially by the plates of a lining holder which holds the friction lining. A pin is provided on the lining support and is able to move perpendicularly to the lining support. When the pin is placed under spring tension as the lining holder is pushed up onto the lining support, the pin extends through an opening provided in the lining holder in such a way that the lining holder is stopped on the lining support by this single pin and cannot move in relation to the lining support. At least one spring in the form of a spring clip acts on the pin. The spring clip can be moved into a raised release position against the force of its own tension, carrying the pin with it.

Abstract: A disk brake for rail vehicles has an actuating device that has a lever designed to transfer deflections of a braking force generator to a pressure element. A parallel alignment of the pressure element, as well as of a brake pad pressed by the pressure element against a friction ring, is guaranteed by at least one slot guide between an at least approximately fixed part of the disk brake and the pressure element. The slot guide has two pins that engage displaceably and offset with respect to one another in two slot path segments which are designed to be at least approximately in the form of a segment of a circular arc and each have different radii.

Abstract: A method and system for controlling the flow of a gaseous medium through a fluid are described. The method includes providing a rheologic fluid through which a gaseous medium can be conducted, and controlling the viscosity of the rheologic fluid to control the flow of the gaseous medium. The system has a rheologic fluid, which is located in particular in a device to be controlled, a guide guiding the gaseous medium through the fluid, and a field applier for applying a field at least partially in the area of the rheologic fluid.

Abstract: An air-drying system, in particular for the pneumatic braking systems of rail vehicles, including at least two air-drying chambers (1L, 1R) interconnected with one another via first and second regeneration lines (2 and 2'). In a reversibly switchable manner one of the chambers is used for air drying and the respective other chamber is used for regeneration of the air-drying agent (adsorbate) contained in the chambers. The second regeneration line (2') can be switched on and off as necessary to provide two different flow rates of regeneration air.
