The invention discloses a flexible framework used for a railway vehicle bogie and provided with slewing bearings, the whole framework is H-shaped and is composed of two T-shaped beams and two sets of slewing bearings connecting the two T-shaped beams, each T-shaped beam is composed of a beam extending in the longitudinal direction and a cross beam extending towards the middle in the transverse direction, and the two T-shaped beams are connected through the two sets of slewing bearings. The two sets of slewing bearings are coaxially arranged in the mode that the axes are parallel to cross beams of the T-shaped beams, the cross beams of the two T-shaped beams are hinged along a transverse shaft, the two T-shaped beams can freely rotate around the axes of the two slewing bearings through connection of the two sets of slewing bearings, and meanwhile the two T-shaped beams are connected in an approximately rigid mode in other directions. The bogie adopting the flexible framework has extremely low torsional rigidit
