  • 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: 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.
