Patent ID: 7708157

Claim:
An automatic central buffer coupling for a rail-mounted vehicle comprising: a coupling head; a coupling rod connected to the coupling head; a bearing block to which the vehicle-side end of the coupling rod is articulated so as to be horizontally pivotable; a fixing plate attachable to an underframe of the vehicle to secure the central buffer coupling to the vehicle; and a shock absorber comprising a destructively-configured force-absorbing member in a form of a deformable tube with its coupling head-side end against the bearing block and its vehicle-side end against the fixing plate; wherein the shock absorber comprises a bolted connection which axially braces the bearing block, the deformable tube and the fixing plate, and which allows an axial displacement of the bearing block relative to the fixing plate upon excessive impact; wherein the automatic central buffer coupling further comprises a controllable linear drive for the axial displacement of the coupling rod relative to the fixing plate, the linear drive being disposed within the deformable tube, and the bearing block comprises a first bearing block component against which adjoins the coupling head-side end of the deformable tube and a second bearing block component to which the vehicle-side end of the coupling rod is articulated; wherein the second bearing block component is axially displaceable relative to the first bearing block component by the linear drive.
