摘要： A rail vehicle bogie brake has a brake beam (4, 5), which at its end is provided with a brake block holder (8) having a brake block (9) for brake application against a tread of a wheel. The brake block holder has a transverse cylinder (19) for its pivotable connection with the brake beam. A mounting shaft (14) is attached in the end of the brake beam and is provided with a sleeve (16). The sleeve engages the mounting shaft and has an outer diameter corresponding to the inner diameter of the cylinder. A sleeve plate (17) is held against the sleeve, which is slightly longer than the cylinder, by means of screws (18) attached in the mounting shaft and prestressing the sleeve.

摘要： A rail vehicle bogie comprises whell sets (1) journalled in longitudinal side frames (3) connected by a transverse bolster (4). A bogie brake therefore compriese transverse brake beams (5, 6) with brake actuators (10) and connecting push rods (11), each brake beam having at each end a brake block holder (8) and being suspended by suspension links (7). Each suspension link (7) is pivotably connected to an assocaited brake block holder (8) at a level substantially corresponding to the center of an associated wheel (2) and at a lower level to its beam (5, 6).

摘要： An end piece or barrel head (1) for a rail vehicle axial slack adjuster is at its outer periphery connected to a barrel (2) of the adjuster and is arranged around a rotatably and axially movable tube (3). The end piece is provided with an internal, circumferential groove (4), connected to the exterior by means of a number of channels (5) opening in the end wall (1') of the end piece for allowing water collected in the groove to freely pass out to the exterior. The end piece is extended further into the barrel by means of a sleeve (1"), which is connected to the groove by means of notches (6) and contains a sealing ring (7) engaging the tube and sealingly cooperating with the sleeve.

摘要： A block brake actuator comprises in a housing (1) a service brake arrangement, including an electric motor (25, 26) and means (43, 44) for transforming its rotary movement into an axial movement of a push rod (45), and a safety brake arrangement, including at least one powerful spring (11), which acts in a brake application direction, may be tensioned at a service brake application and may be locked to the housing in a tensioned state. The spring is arranged transverse of the push rod and acts thereon over a wedge (8) and roller (5, 7) arrangement.

摘要： In a sealing arrangement between a tubular housing (2) and a rod (1) in a rail vehicle slack adjuster, a cup (3) is movable with the rod and extends along the rod over the free end of the housing. A sealing arrangement (6-9) is in sealing engagement with the housing (2). It comprises flange-like portions (6', 7), extending into close proximity with the inner wall of the cup for forming a labyrinth seal, and a sealing lip (9') in sealing contact with the end of the cup for preventing the intrusion of water and the like in the cup.

摘要： A brake actuator for delivering a brake force through a brake block or brake pad to a wheel or disc to be braked comprises in a housing (1) a service brake arrangement (3, 5). The actuator also comprises a safety brake arrangement (4, 9) including at least one powerful spring (9), acting in the brake application direction, means for tensioning the spring by the reaction force at a service brake application, and mechanical means (11, 12, 13) for locking the spring to the housing in a tension state. These locking means can be released at will for accomplishing a safety brake application.

摘要： A rail vehicle bogie comprises a tranverse bolster (1), two side frames (2) and two wheel sets (3) with wheels (4). A bogie brake comprises between the two wheel sets two tranverse brake beams (5) arranged to be pressed apart by brake actuators (11) for braking engagement by brake blocks (6) at the ends of the brake beams with the treads of the wheels. According to the invention the brake actuators (11) are arranged in the brake beams (5) close to the wheels (4) and are integrated in the beams, which otherwise are built-up of plate profiles (15).
