Swing Head Patents (Class 213/18)
  • Patent number: 8091717
    Abstract: A central buffer coupling having a coupling head, a coupling shaft and a bearing block attachable to the front face of a car body. The coupling shaft includes a front shaft component supporting the coupling head and a rear shaft component coupled to the bearing block so as to be horizontally pivotable which are pivotable in the horizontal plane relative one another about a rotational axis defined by a connecting pin, and the central buffer coupling further includes a pivoting mechanism to pivot the front shaft component relative the rear shaft component. The pivoting mechanism includes a slotted gate fixedly attached to one of the two shaft components and having a sliding guide, a cam disc rotatably mounted about the rotational axis defined by the connecting pin and having a cam disc guide, and a bolt connecting the one to the other of the two shaft components.

  • Patent number: 7513376
    Abstract: The present invention relates to a central buffer coupling for rail-mounted vehicles having a coupling shaft arranged to be vertically pivotable around an articulated housing of a railway vehicle and supporting a coupling head and a device for horizontal resetting to center at its free end. In order to realize a disengaging of the frictionally-locked connection between an actuating means of a center position device and a coupling shaft in the event of a crash; i.e., upon extreme impact/tractive force being transferred through the coupling shaft, a separable center position coupling in accordance with the invention is provided, which disengages the frictionally-locked connection between the actuating means and the center position guide upon a definable critical impact/tractive force being exceeded.

  • Patent number: 7490729
    Abstract: The present invention relates to a center buffer coupling for railroad cars that has a coupling head 1 and a coupling shaft 2 that holds the coupling head 1 on its front end 3, whereby the rear end 4 of the coupling shaft 2 is attached to the frame of the railroad car so that it can swivel horizontally. In the case of a crash, i.e. during the occurrence of extreme impact energies, in order to shorten the coupled couplings in such a way that the energy absorbing elements 22 on the body side dissipate the impact energy transferred between the adjacent car bodies during the impact without additional space being needed when the coupling head 1 is taken out of the force flow, according to the invention, a section 6 of the coupling shaft is formed of a first partial piece 7 and a second partial piece 8, whereby the two partial pieces 7, 8 are connected to each other by means of an overload safety device 9.

  • Patent number: 7055705
    Abstract: A central buffer coupling for coupling a first rail car body with a second, adjacent rail car body of a multiple-unit rail vehicle, has a coupling head pivotally connected by a coupling shaft to a linking housing of the rail car body, and a pivoting unit pivoting the coupling shaft. The pivoting unit has a guide participating in horizontal pivoting of the shaft that runs about a vertical pivot axis. Pressure surfaces symmetrical to the longitudinal axis of the shaft which correspond to a respective pressure device, bring about horizontal re-centering of the shaft. The respective pressure devices are supported on the linking housing of the shaft to bias the related pressure surfaces against the guide. The guide is positionable with the action-linked coupling shaft in every position of the planned pivot region, via an activation device.

  • Patent number: 5472104
    Abstract: The present invention pertains to a central buffer coupling for rail-borne vehicles with a two-part coupling shaft formed by a front shaft part (2) carrying the coupling shaft (1) and by a rear shaft part (3) hinged horizontally pivotably to the chassis of the rail-borne vehicle, wherein the two shaft parts (2 and 3) of the two-part coupling shaft are connected to one another by a vertical connecting pin (5). A locking bar (7), which is displaceable in the longitudinal direction to a limited extent in the coupling shaft, is provided as the fixing device, and the said locking bar can be displaced, in the mutually extended position of the two shaft parts (2 and 3), by the force of a spring (13), into a locked position, in which the locking bar (7) associated with one of the shaft parts (2 or 3) engages the vertical groove (6) associated with the other shaft part (3 or 2) to make the coupling shaft rigid.
