WHEEL SET WITH ADJUSTABLE TRACK FOR RAILWAY TRANSPORT Russian patent published in 2009 - IPC B61F7/00 

FIELD: transportation.

SUBSTANCE: wheel set with adjustable track comprises axis (100), having sliding part, wheel (200) installed on sliding part, support cup (300), which is rigidly fixed on axis part. According to the first version, locking block (500) is installed on support cup with the possibility of turn so that control of wheel side motion is realized by means of locking block rotation. Flange (400) provides for control of locking block closure and opening. Compressible spring (600) is installed between flange and holder (700) of spring. According to the second version, wheel has through opening for axis insertion in it, at that protruding part exits specified part near annular edge of through hole, and multiple locking elements are arranged on annular external surface of protruding part. Locking block is installed on support cup with the possibility of rotation so that control of wheel motion in axial direction is realised by circular motion of locking block. Flange provides for locking block rotation in direction of unblocking rail action and locking block turn in opposite direction by means of compression spring. Spring holder is fixed to support cup.

EFFECT: possibility is provided for automatic variation of track, easy manufacturing, assembly and disassembly of device, reduced number of components.
