FIELD: transport.
SUBSTANCE: connection contains supporting adaptor (1) of axle bearing (2) and flexible shock-absorber (3) installed in pedestal jaw of side frame (5) of freight van bogie between base surfaces of pedestal jaw of side frame and supporting adaptor of axle bearing. Flexible shock-absorber is made of V-shape elastomer with base angle α=140÷170° with lateral stiffness calculated as per formula Stiflat=P:(33.5÷38.5) and longitudinal stiffness calculated as per formula Stiflong=P:(55.5÷71.5) as related to longitudinal bogie axle for securing of flexible shock-absorber deformation in lateral and longitudinal planes, where P is vertical load on wheelset axle.
EFFECT: improvement of negotiation of van in curved sections of railway lines.
