The invention provides a single-wheel-pair hinged type middle bogie. The single-wheel-pair hinged type middle bogie comprises walking wheels, an unsprung framework, a secondary suspension system, a sprung framework and a hinged device. The number of the walking wheels is two, and the walking wheels are arranged on the two sides of the unsprung framework correspondingly; the hinging device comprises a bottom spherical hinge assembly and a top spherical hinge assembly; the bottom spherical hinge assembly is arranged at the bottom of the main framework, and the sprung framework is connected with the bottoms of the two adjacent carriages through the bottom spherical hinge assembly. The top spherical hinge assembly is arranged at the top of the main framework, and the main framework is connected with the top of any one of the two adjacent carriages through the top spherical hinge assembly; and the secondary suspension system is arranged between the sprung framework and the unsprung framework. According to the single-wheel-pair hinged type middle bogie, the curve passing performance and the running stability performance of a train are improved, abrasion of the walking wheels is greatly reduced, and the single-wheel-pair hinged type middle bogie is suitable for light rubber wheel overhead sightseeing trains of our company.
