Double-T-shaped framework elastic hinging flexible suspension direct driving radial steering frame

Abstract

The invention relates to a double-T-shaped framework elastic hinging flexible suspension direct driving radial steering frame, which comprises a steering frame framework, a shaft box device (4) and two permanent magnet direct driving motors (3), wherein the shaft box device (4) is used for positioning wheel pairs (5); the permanent magnet direct driving motor (3) is used for driving the wheel pairs (5); the steering frame framework is a double-T-shaped elastic hinging framework with the flexible function; each of the two permanent magnet direct driving motors (3) is arranged on a steering frame framework through a three-point type suspension mechanism, and respectively drives one wheel pair (5). Compared with the prior art, the double-T-shaped framework elastic hinging flexible suspension direct driving radial steering frame has the advantages that the flexible function of the steering frame is good; the adapting route twisting capability is high; the unsprung mass is light; the operation noise is low; the active radial function is realized, and the like.

Description

Technical field [0001] The invention belongs to the technical field of rail vehicle bogies, and relates to a rail vehicle flexible frame suspension direct-drive radial bogie, in particular to a flexible frame suspension direct-drive radial bogie with a double T-frame elastic articulation. Background technique [0002] The traditional bogie adopts an H-shaped frame and rigid beams, and only relies on a series of vertical flexibility to overcome the distortion of the line, and the bogie has a poor ability to adapt to the distortion of the line. [0003] After searching, it was found that the Chinese invention patent CN105665049B discloses an articulated frame linear motor bogie, two T-frames are hinged to the side beams through rubber nodes respectively; another Chinese invention patent CN102975734A, which discloses a flexible center beam Permanent magnet direct drive flexible bogie with plate structure. [0004] For these two types of flexible frames, the beams cannot bear the load, ...

AI Technical Summary

Problems solved by technology

[0006] The positioning stiffness of traditional bogie wheelset should not be set too small in order to give consideration to stability, which limits the ability of the wheelset on the curve to be guided by the creep moment, resulting in an angle of attack when the wheelset passes the curve, resulting in wheel-rail wear and curve "whistling". Call"

[0007] The curve passing performance of the bogie after adding the forced guiding mechanism is improved, but the isotropic performance of the bogie passing through the curve cannot be significantly improved due to the complexity and wear of the guiding mechanism
