摘要： A change-over valve (or a so called empty-load valve), preferably for a railway vehicle, having a valve device (16, 31-35) opening or closing a pneumatic passageway depending on the position of a mechanical operating system or in other words the load on the vehicle. In order to improve the working range of the external operating arm (4) and the exactness of the change-over point the operating system is a force transmitting chain from said operating arm to the valve device (16, 31-35) via a spring (9), a knee lever (13), and a valve operating rod (14) in such a geometrical way that the axis of the spring is substantially perpendicular to the valve operating rod.

摘要： A slack adjuster for a rail vehicle brake system, comprising a brake force receiving adjuster tube (1, 1A), a spindle (4; 4A) axially movable therein, and two nuts, an adjuster nut (5; 5A) and a leader nut (6; 6A), which are in non-self-locking thread engagement with the spindle and are held resiliently in clutch engagement with a clutch ring (7; 7A) and a control sleeve (16; 16A) respectively, the latter being axially movable in the tube a distance (A) corresponding to the desired slack. In order to transform this so called stroke-sensing adjuster into the so called clearance-sensing type being independent of the elasticity part of the application stroke the adjuster nut (5; 5A) and the clutch ring (7; 7A) in coaction are arranged to submit a force to the leader nut (6; 6A) for locking the latter against rotation under deformation of a resilient element (13; 30; 34; 38; 5A) at the occurence of a counter-force on the spindle (4; 4A) during the brake application.

摘要： A fluid pressure actuated brake unit has a push rod (3) axially movable in a housing (1) and a piston (2) with a wedge element (7) axially movable substantially perpendicular thereto. A wedge surface (12) on the wedge element is arranged to transmit a force from the piston to the push rod via a working roller (8) on the push rod. In order to reduce the dimensions of the wedge element (7) and to give a smooth transition from the brake application stroke to the brake operation stroke the wedge surface (12) at its end remote from the piston (2) has an edge (13) intended for coaction with the working roller (8) during the brake application stroke.
摘要翻译：流体压力致动的制动单元具有可在壳体（1）中轴向移动的推杆（3）和具有可沿其基本上垂直于其轴向移动的楔形元件（7）的活塞（2）。楔形元件上的楔形表面（12）布置成经由推杆上的工作辊（8）将力从活塞传递到推杆。为了减小楔形元件（7）的尺寸并且使得从制动施加行程到制动操作行程的平滑过渡，在远离活塞（2）的端部处的楔形表面（12）具有边缘（13）），用于在制动施加冲程期间与加工辊（8）共同作用。

摘要： Un frein electromagnetique de rail pour un vehicule de chemin de fer comprend une bobine allongee d'actionnement de frein (1), un chassis rigide (21, 43), et une pluralite de patins de freinage en forme de U (23, 24) montes dans une rangee sur le chassis. Afin d'ameliorer la transmission des forces de reaction de freinage depuis les patins jusqu'au vehicule chaque patin de freinage (23, 24) est individuellement mobile vers le bas par rapport au chassis (21, 43) et est maintenu sous tension par un ressort. Une tige de liaison (33) s'etend le long de la branche inferieure de la bobine, et engage chacun des patins de freinage de maniere a assurer la transmission des forces de reaction de freinage depuis les patins jusqu'a la tige de liaison. Un organe (39) monte rigidement sur le chassis du vehicule (42) est connecte a l'extremite de la tige de liaison pour reprendre les forces de reaction de freinage transmises a la tige de liaison.

摘要： An Arrangement on a railway vehicle for enabling a block brake actuator (1) to coact with the tread of a corresponding wheel (2) irrespective of lateral movements thereof. The actuator (1) is suspended (by members 3-6) so as only to be laterally movable and is guided in the lateral direction by a member (7) moving together with the wheel (2) and/or by the wheel itself.

摘要： Suspension pour une unite de frein a disque (1) de vehicule sur rail comprenant une console de suspension (11) destinee a etre fixee au boggie ou au chassis du vehicule, un berceau (13) fixe de maniere mobile a la console, et des liaisons de suspension (17, 18) reliant de maniere pivotante les supports (6) de patins de frein au berceau. Une connexion ulterieure de support (19-21) est prevue entre la console et l'unite de frein. Afin d'obtenir la mobilite desiree pour le disque de frein pendant le freinage, un joint (14) est place entre la console (11) et le berceau (13), ce joint etant rigide dans la direction de transmission de la force de freinage mais relativement elastique dans les autres directions. La connexion de support (19-21) possede fondamentalement les memes proprietes.
