Abstract:
A bogie suspension traction device for use in a low-floor articulated rail vehicle, and the device comprises a bolster assembly (6), a traction linkage assembly (7), a single-stage suspension assembly and a two-stage suspension assembly (8); the two-stage suspension assembly is mounted between the bolster assembly and a frame of the bogie (2); two sets of the bolster assemblies and two sets of the traction linkage assemblies are respectively provided; the two sets of bolster assemblies are disposed in the middle of two pairs of wheels (4), respectively; each bolster assembly is connected to the frame by means of one set of traction linkage assembly (7), and each bolster assembly is connected to a vehicle body by a revolving mechanism (101). The device has a simple and compact structure, and is light-weight; during the operation of the vehicle, traction and braking forces may be better transmitted, vertical, horizontal and longitudinal loads may be better borne, and the small-curve negotiation ability of the vehicle may be greatly improved; meanwhile, the floor height may be reduced, thereby notably improving the driving performances of the vehicle.
