The invention relates to an ultra high speed test CRH train bogie and belongs to the field of railway vehicle bogie devices with elastic deformation buffering capacity, the problem of welding stress centralization is solved by a horizontal and longitudinal beam integrated type tray frame, and a wing-shaped elastic support arm of an elastic frame can have a damping effect by own elastic deformation. According to the novel bogie, by the aid of matching usage of the elastic frame and motor suspension devices with vibration absorption functions, high cut-down and inhibition effects can be realized on motor vibration, and accordingly, the vibration frequency control difficulty of a power system is reduced greatly and surplus vibration damping buffering components can be effectively cut down, so that redundant components can be simplified greatly, the structure dimension is shortened, and the weight is reduced. Master pin backward titling structures of traction wheel sets can swing consistently in S shapes. The ultra high speed test CRH train bogie can overcome inherent mutual contradiction of dual requirements on two aspects of lightweight design and speed lifting of a 500km/h ultra high speed train and is a novel breakthrough in the field of localization ultra high speed bogies.
