DIESEL LOCOMOTIVE Russian patent published in 2017 - IPC B61F5/00 

FIELD: transport.

SUBSTANCE: invention relates to railway vehicles, namely to diesel locomotives. Diesel locomotive consists of a body connected with a pair of 3-axle bogies by means of pins and the central suspension arranged in the form of helical compression springs. On each of the bogies in their longitudinal plane at equal distance relative to the axis of symmetry passing through the pins there are elastic rods. One ends of the rods are equipped with levers interacting with the body bottom, and the other ones – with splines moving in supports rigidly fixed on the bogies. Each of the elastic rods with its splines is interconnected with mating splines made in the jars of square cross-section movably installed in one of the supports. Inside the jars there are helical compression springs in contact both with their inner end walls and with ends of the elastic rods. Each of the jars with outer end inclined surfaces interacts with blocks of a wedge shape movably installed in guides rigidly secured on the bogies.

EFFECT: provided is development of the central locomotive suspension, which enables to automatically change the rigidness characteristics.
