Diesel locomotive non-pedestal bogie

FIELD: transportation.

SUBSTANCE: invention relates to railway vehicles, namely to non-pedestal diesel locomotive bogies. Diesel locomotive non-pedestal bogie consists of a frame with mounted on it motored wheeled units and wheel pairs with axle boxes. Axle boxes the of wheel pairs are spring-loaded relative to the frame by helical compression springs and with the help of shackle links are bound with it.
