Abstract: A railroad freight car brake beam with a strut having a pair of generally parallel and joined side walls disposed to opposite sides of an axis of the strut and having a central hollow portion along with a longitudinally elongated slot adapted to be inclined a predetermined number of degrees from vertical for accommodating an elongated brake lever extending through the strut. Each side wall of the strut defines a bore opening to the hollow center portion and to an exterior of the strut. The bores defined by the strut are aligned relative to each other to accommodate at least a lengthwise portion of a brake lever pivot pin extending through the strut and serving to connect the brake lever to the strut. The aligned bores in the strut also define a pivot axis for the brake lever. The strut further includes a pair of bushings which journal the brake lever pivot pin. One bushing is accommodated in each bore defined by the strut.

Abstract: A limit switch device for an actuator comprises a brake rod, a mounting frame and two switches. The brake rod is axially movable with respect to the mounting frame. The two switches are mounted on the mounting frame and located in the axial direction of the brake rod and are connected to the actuator, respectively. When the actuator moves to the end of its travel, it will drive the brake rod to move and switch on one of the switches, and the switch will stop the actuator.
Abstract: 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.
