RAILWAY VEHICLE BODY TO THE BOGIE CONNECTION DEVICE Russian patent published in 2018 - IPC B61F5/52 

FIELD: transportation.

SUBSTANCE: invention relates to the rolling stock design. Railway vehicle body with bogie connection device consists of multifunctional supports fixed on the bogie side frames, and connected by the transverse beam with notches, and mounted on the pivot ring with rods attached to them. Rods are located symmetrically about the body vertical axis at some angle to the horizontal line and are oriented perpendicular to the body longitudinal axis. These rods other ends are pivotally connected to the located in the transverse beam profiled horizontal guides composite friction slides and contacting with internal and external helical springs axially located in this beam. In the car empty condition, with horizontal body oscillations relative to the bogie, the internal springs operate together with the friction sliders, and in the loaded one are the inner and outer springs. Side supports upper and lower supports brackets are installed with a gap ensuring reduction in these supports elastic elements dynamic loading during the car negotiation into the curve.

EFFECT: result is improvement in the car dynamic characteristics, increase in the train's movement safety, reduction in the wheels sets flanges and rails heads wear intensity.
