Abstract

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.

Description

Technical field [0001] Technical Field The present invention relates to coaches, particularly relates to a single-round of the intermediate articulated bogie. Background technique [0002] At present, many tire train type, its bogie structure is divided into uniaxial and biaxial tire rubber wheel bogie bogie two kinds. The biaxially common bogie including tire traction motor, gearbox, brake base member, two sets of running wheels, auxiliary wheels, the power boots, air springs and stabilizing wheels; said traction motor powered by the power receiving shoe which an output terminal connected to the gear box; two groups of running wheels are connected through the shaft to the gear box; with the same number of running wheels of the auxiliary wheel, and the train along the longitudinal direction symmetrically disposed at both sides of the two running wheels; the said stabilizing wheels disposed immediately below the two travel wheels; said air spring is disposed directly above the two...
