FIELD: transport.
SUBSTANCE: invention relates to three-stroke mechanism control wheel (40), in which there is bushing (46) set in superstructure center, having axial symmetry of n-th order, wherein superstructure contains n-th number of radial arms (48) and n-th number of columns (44), passing parallel to column wheel axis of rotation, wherein columns are uniformly distributed along column wheel circumference and separated from each other by n-th number of cavities, forming same number of holes between columns.
EFFECT: according to the invention in column wheel width of columns (44) exceeds width of holes between columns, as well as by that arms (48) width is less than one half of columns (44) width.
