Embodiment Construction
[0050] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0051] Such as figure 1 As shown, a low-floor articulated rail vehicle bogie suspension traction device is installed on a low-floor articulated rail vehicle. The rail vehicle includes a plurality of carriages, and a bogie 1 is installed below the junction of every two carriages. The carriages are respectively connected with the bogie 1 through a slewing mechanism 101 .
[0052] The bogie 1 includes a frame 2, a suspension traction device 3, a wheel pair 4, a drive motor (not shown in the figure), a brake, etc., and four drive motors are used to drive four wheels 5 respectively, and the four drive motors and brakes are respectively fixed Installed on the mounting beams 81 on both sides of the frame 2, the drive motor and the brake are installed on the outside of the wheels 5, which is conducive to reducing the height of the floor.

The invention relates to a hanging traction device of a bogie of a low-floor hinged type railway vehicle. The hanging traction device comprises two sets of swing bolster assemblies, two sets of traction pull rod assemblies, primary spring assemblies and secondary spring assemblies. The secondary spring assemblies are mounted between the swing bolster assemblies and a framework of the bogie. The two sets of swing bolster assemblies are arranged between two wheel sets correspondingly. Each set of swing bolster assembly is connected with the framework through the corresponding traction pull rod assembly, and each set of swing bolster assembly is connected with a vehicle body through a slewing mechanism. The hanging traction device is simple and compact in structure and low in weight, transmission of traction and brake force during vehicle operation can be better achieved, vertical, transverse and longitudinal loads can be borne, and the small curve passage capacity of the vehicle is greatly improved; and moreover, the height of a floor face can be reduced, and the vehicle driving performance is greatly improved.
Description
technical field [0001] The invention relates to a bogie of a rail vehicle, in particular to a bogie suspension traction device used on a low-floor articulated rail vehicle, and belongs to the technical field of rail vehicle manufacturing. Background technique [0002] Low-floor urban rail vehicles play an increasingly important role in many urban traffic, and in low-floor urban rail vehicles, the bogie is the most important structural component, and its structure and various parameters directly determine the stability of vehicle operation and ride comfort. The bogies of existing low-floor urban rail vehicles generally have problems such as poor ability to pass through small curves, high floor surface, difficulty in getting on and off, and heavy traction devices. With the continuous progress of urban rail vehicles, the requirements for urban rail vehicles are getting higher and higher. Therefore, it is necessary to provide a low-floor hinge that can lower the floor surface t...
