TRACK POWER ABSORPTION DEVICE TO PROTECT PASSENGER ROLLING STOCK Russian patent published in 2009 - IPC B61G11/16 

FIELD: railroad transport.

SUBSTANCE: invention relates to track power-absorbing devices intended for protecting rolling stock against damages and passengers against injuries (PAD) in emergent collusions between train and fixed buffers at railway terminal passenger platforms. PAD comprises power absorption elements assembled on fixed support. 1^st stage power absorbing element represents a pipe with its one end fitted with shock-receiving top, and its other end arranged in the draw plate attached to moving support plate mounted on power absorbing element of the following stage. Note here that last stage draw plate is attached onto fixed support plate mounted on the base that has a cavity with sizes exceeding those of last stage power absorbing element. Note also that shock-receiving top represents a head part of CA-3 automatic coupling. Forward part of outside surface of every power-absorbing element and working surface of mating draw plate represent right and reversed cones with approximating angles of opening. Mind that outer diametre of absorbing element cylindrical part exceeds that of draw plate hole, while draw plate cone angle exceeds that on power absorbing element pipe.

EFFECT: higher power capacity and preset performances of emergent braking equipment.
