141 | Halterungsanordnung für querbewegliche Bremsklotzeinheiten an Schienenfahrzeuge | EP94102556.1 | 1994-02-21 | EP0624506A1 | 1994-11-17 | Marschang, Herbert Karl; Staltmeir, Josef; Kerscher, Albert |
Die Halterungsanordnung für querbewegliche Bremsklotzeinheiten (1) ist als ein parallelogrammartiges 4-Gelenk-Hebelwerk ausgebildet, welches einerseits, fahrzeugradseitig, am Fahrzeugrahmen (20) und andererseits an der Oberseite einer Bremsklotzeinheit (1) jeweils um vertikale Drehachsen (12) drehbar angelenkte, horizontal und im wesentlichen in Fahrzeuglängsrichtung verlaufende Halterungshebel (15) aufweist. Die Halterungshebel (15) können zur Vergrößerung ihrer Anlenkbasis und Versteifung doppelwangig mit 2 Hebelwangen (13, 14) ausgebildet sein. Insbesondere bei um eine horizontale, zum Fahrzeug quer verlaufende Querachse (9) schwenkbarer Anlenkung der Bremsklotzeinheit (1) an den Halterungshebeln (15) ist am unteren Ende der Bremsklotzeinheit (1) eine Drehmomentabstützung vorzusehen, welche als zu einem Widerlager (7) führender Pendelhebel (6) oder als Zugstange ausgebildet sein kann, welche das Fahrzeugrad (5) überquert und mit einer andersseitigen Bremsklotzeinrichtung gekoppelt ist. Bei konischer Ausbildung der Lauffläche des Fahrzeugrades 5 können die Halterungshebel (15) in Normallage um den Konuswinkel oder einen etwas größeren Winkel zur Fahrzeuglängsrichtung geneigt angeordnet sein, derart, daß sie etwa rechtwinklig zur Radlauffläche verlaufen; bei dieser Anordnung ergibt sich zumindest eine Kompensation der auf den Bremsklotz (3) infolge der konischen Radlauffläche einwirkenden "Hangabtriebskraft". Infolge der im wesentlichen horizontalen Längserstreckung der Halterungshebel (15) erfordert die Halterungsanordnung für die Bremsklotzeinheit (1) nur eine geringe Bauhöhe und ist daher ohne Behinderung durch andere Bauelemente am Schienenfahrzeug unterbring- und montierbar. |

Der Bremsklotz weist eine Vielzahl von in einer schwalbenschwanzartigen Führungsbahn 2 eines Bremsklotzhalters gehaltene Reibklötze 3 auf. Zum Längenausgleich der Wärmelängsdehnungen der Reibklötze 3 ist ein Verschlußteil 9 für die Führungsbahn gegen die Kraft einer Feder 25 verschieblich gelagert, die Feder 25 weist dabei eine die max. an den Reibklötzen 3 angreifende Verschiebekraft übersteigende Vorspannung auf. Zum manuellen Entspannen und Wiederspannen der Feder 25 bei einem Wechsel der Reibklötze 3 ist eine als Nocken 31 oder dergleichen ausgebildete Vorrichtung mit integrierter Übersetzung vorgesehen; infolge der Übersetzung ist die Feder manuell spannbar. Es können außerdem Anordnungen (Steigung 37) vorgesehen sein, welche dem Ausgleich der herstellungsbedingten Längentoleranzen der Reibklötze 3 dienen. Die Feder kann dann relativ kurz und hart ausgebildet werden. |

A parallel beam brake apparatus for dual and triple axle trucks and a single beam brake apparatus for single axle trucks each comprise spaced, pivotably mounted bell crank levers (30) which engage a fluid operable actuator (38) between one pair of arms (32) and engage a pair of push rods (58) with the remaining arms (34). Improved spherical joints (60) between the arms and the push rods facilitate force transmission without allowing push rod rotation. A unique pivot geometry between the bell crank levers and the brake beams facilitates assembly and improves stress distribution between the levers and the beams. The actuator (38) includes a slack adjustor mechanism (40) in which a spiral power spring unwinds to drive a lead screw and take up slack or is wound by the rotating, translating lead screw to add slack. |

155 | Railway brakes | EP80302842.2 | 1980-08-18 | EP0025290A1 | 1981-03-18 | Bayliss, John Patrick |
A tread brake for braking a wheel (2) of a railway vehicle which is sprung relative to a frame (4) of the vehicle, comprises an actuator (5) suspended from the frame (4) by a swing arm (6), and a rigid link arm (7) fixed to the actuator (5) and connected through a pivot (8) parallel to the wheel axis to a bracket (9) fixedly mounted to a bearing in which the wheel axle is journalled. The link arm (7) adjusts the position of the actuator (5) in response to any movement of the wheel (2) relative to the frame (4) so that the braking element is always applied substantially radially to the wheel, which allows the element to take the form of an elongate rod of friction mater- , ial. |

A system for operating a locomotive parking brake includes a wheel brake, a coupling connected to the wheel brake, and means for applying force to the coupling. A sensor connected to the coupling measures a force applied to the coupling and generates a signal reflective of the force applied to the coupling. A method for operating a locomotive parking brake includes applying a force to a coupling connected to a wheel brake, measuring the force applied to the coupling, and comparing the force applied to the coupling to a first predetermined limit. The method further includes indicating that the force applied to the coupling is equal to or greater than the first predetermined limit. | ||||||
