CAR BODY BOLSTER HANGER Russian patent published in 2011 - IPC B61F5/02 

FIELD: transport.

SUBSTANCE: invention relates to railway machinery. Car body bolster hanger comprises separate assemblies of body hanging to every bogie. Assemblies of flexible hanger are arranged in symmetry on both sides of the bogie, attached to the bogie and car body to allow its flexible displacements and angular turns in spatial vibrations relative to bogie. Hanger is equipped with stiffness equaliser. The latter is arranged between bolster hanger assembly and made up of flexible rings contracted to oval shape. Said rings are arranged in symmetry on both sides of the bogie and pin-jointed at diametrically opposite points to car body and bogie. One of said joints is provided with height adjustment mechanism.

EFFECT: higher total positive stiffness, improved anti-vibration properties.
