Abstract (en)

The brake device has a brake pad (12) acted on by at least one spring packet (16,17), for biasing it against a rail (18), and a wedge-shaped brake pad (13,14) between the opposite side of the rail and a housing (11). The surfaces (41,42) of the pad are inclined to the vertical. Angled rolling plates are provided between the wedge-shaped brake pads and the housing surfaces.

Abstract (de)

Die Bremsfangvorrichtung weist eine erste durch zwei Federpakete (16, 17) belastete Bremsbacke (12) auf. Die erste Bremsbacke (12) wirkt mit einer Schiene (18) zusammen und ist mit Querrillen (57) versehen. Auf der gegenüberliegenden Seite der Schiene (18) ist eine untere und eine obere keilförmige Bremsbacke (13, 14) angeordnet. Die Bremsbacken (13, 14) weisen je einen in einer Öffnung gelagerten Wälzkörper (30, 31) auf. Zwischen schrägen Flächen (41, 42) des Gehäuses (11) und schrägen Flächen (64, 65) der unteren und oberen Bremsbacke (13, 14) sind abgewinkelte Rollplatten (43, 44) angeordnet. Zwischen der oberen Rollplatte (44) und der schrägen Fläche (42) des Gehäuses (11) sind Unterlagsplättchen (71) vorgesehen. Konzentrisch zu Schrauben (49, 50) angeordnete Druckfedern (47, 48) drücken die Rollplatten (43, 44) mit ihren kurzen Schenkeln (53, 54) gegen das Gehäuse (11). Die Bremsfangvorrichtung bremst nach unten und oben und ist einfach aus dem Fang zu lösen. Durch die Anordnung der L-förmigen Rollplatten (43, 44) kann die erste Bremsbacke (12) ohne schiefe Ebene hergestellt werden, was eine kostengünstigere Herstellung zur Folge hat. Dank der symmetrischen Ausbildung des Gehäuses (11) wird nur eine Gehäuseausführung für links und rechts, oben oder unten am Lift gebraucht. <IMAGE>
