EIGHT-AXLE RAIL ROAD CARRIAGE Russian patent published in 2021 - IPC B61F3/06 B61F5/20 

FIELD: railway vehicles.

SUBSTANCE: invention relates to the field of railway vehicles, in particular to eight-axle rail vehicles. The body of the crew rests on two four-axle bogies. Four-axle bogies contain two biaxial bogies and a connecting beam. The body is connected to the connecting beam and rests on the bolster beams of the biaxial bogies. Cross beams with a center plate and elastic elements at the ends are installed on the thrust bearings of the bolster beams. The upper part of the elastic elements is made in the form of rollers and interacts with the body, and the lower part - with the side bolsters of the bolsters. The ends of the cross beams can interact with brackets that prevent the beams from rotating relative to the body. Holes are made at the ends of the connecting beam to accommodate the center plates of the cross beams. Elastic elements of different stiffness are installed in the pivot seat of the connecting beam. Elements of lower rigidity interact with the pivot when moving the connecting beam by ±20 mm, and those of greater rigidity - when moving from ±20 mm to ±40 mm.

EFFECT: dynamic characteristics of the crew are increased.
