FIELD: transportation.
SUBSTANCE: invention relates to the field of running gears of railway vehicles. Running assembly comprises two systems of wheel pairs with two frames and hinge joint assembly. Every system comprises two wheels. Wheels are installed on separate axles. Axes are installed in pairs in common frame. Frames are connected by hinge. Hinge is located on longitudinal axis of bogie and allows to transmit traction and compression forces between two frames without changing distance between wheels. Hinge can consist of two curved connecting rods crossed in form of scissors. Two bodies of adjacent rail vehicles can be installed on one described undercarriage.
EFFECT: reduced wear in wheel-rail system.
