Integral Tension And Compression Member Patents (Class 188/226.1)
  • Patent number: 9365221
    Abstract: A strut for a brake beam assembly includes a strut body extending along a longitudinal axis between a proximal end and a distal end. At least one slot is defined in the strut body and receives and supports a brake lever extending non-parallel to the longitudinal axis. A compression member engager is connected to a distal end of the strut body and is configured to connect the strut body to a compression member of the brake beam assembly. A tension member engager is connected to the proximal end of the strut body and is configured to engage a tension member of the brake beam assembly. At least one fastener is configured to engage the compression member engager to fasten the compression member engager on the compression member. At least a portion of the strut body is rotatable about the longitudinal axis with respect to the compression member engager and the tension member engager to be oriented at opposing angles with respect to a horizontal plane extending through the longitudinal axis.

  • Patent number: 8251187
    Abstract: The invention relates to a pneumatic brake device having a spindle movable in the axial direction and a yoke, on which the spindle is supported such that a rotation of the spindle is prevented. According to the invention, a first and a second yoke toothed ring having sets of teeth (8; 10) directed toward each other are connected to the yoke in a rotationally fixed manner. Furthermore, a spindle toothed ring with sets of teeth on both sides is rigidly connected to the spindle between the two yoke toothed rings.

  • Publication number: 20100025170
    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.

  • Patent number: 7527131
    Abstract: An improved railway car truck is provide that includes two sideframes and a bolster. The bolster has laterally opposite ends, each end extending into and supported within a sideframe opening on a spring group. Each sideframe also has a pedestal opening at each end to receive a bearing adapter assembly. The railway car truck also includes two brake beam assemblies supported on the railway car truck bolster and sideframes. Each brake beam assembly includes an elongated main section, a support section, and a standoff section extending between the main section and support section. Two brake hangers comprised of a leg sections and a bottom section support an end of the brake beam assembly. The brake hangers can be reversed such that the brake head support sections can be spaced laterally to adapt to different rail gauges.

  • Patent number: 7165659
    Abstract: A block brake device of a bogie of a rail vehicle containing two wheel sets with two wheels respectively as well as two brake beams each assigned to a wheel axle and extending parallel to the latter, which brake beams carry brake blocks and are mutually connected by way of pressing rods which can be actuated by at least one pressure-medium operated cylinder piston drive for the braking engagement of the brake blocks with assigned braking areas of the wheels. At least a portion of a brake beam forms the cylinder of the cylinder piston drive.

  • Patent number: 6234283
    Abstract: A brake beam structure comprising compression and tension members having an “u” shaped cross section including two side walls and forming a housing, two end extensions having a quadrangular cross section including two side walls, a fulcrum coupled to the compression and tension members and two brake heads, in which: the ends of the compression member are placed inside the housing of the unshaped cross section of the tension member and each of the end extensions are placed inside the housing of the channel shaped cross section of the compression member, the brake beam having two fasteners passing through holes placed at the ends of the tension and compression members at each of “u” shaped cross section side walls and through holes placed at the side walls of the end extensions in order to fasten the tension member, compression member and end extensions, and in which the brake heads are welded to the ends of the tension member.
