2F-shaft bogie

The invention discloses a 2F-shaft bogie, which comprises wheel pair assemblies and swing bolsters, wherein each wheel pair assembly comprises a left wheel assembly and a right wheel assembly which are connected through an axle; the swing bolster is arranged between the two adjacent groups of wheel pair assemblies; braking devices are arranged at the inner sides of the two pairs of wheel pair assemblies; the two adjacent wheels at the same side are connected through a lateral frame; the upper surface of the lateral frame is a saddle-shaped structure with concave middle part; a bearing saddle is arranged at the connection part of the lateral frame and the wheels; and the axle center height of each wheel is 437-477mm. The 2F-shaft bogie disclosed by the invention is applied to train wagons, has the capability of reducing the action force on wheel rails; and under the situation of same bearing force, the lateral frame with the structure has lager elasticity, thereby the impact on the wheel rails is reduced, the axle height is increased, and the carrying capacity of the wagon is improved.
