Embodiment Construction
[0033] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0034] like figure 1 As shown, a low-floor articulated rail vehicle bogie suspension traction device is installed on the driver's cab of the low-floor articulated rail vehicle and the bogie 1 below the first carriage adjacent to the driver's cab, that is, it is installed at the head position On the bogie 1, the bogie 1 is connected with the car body 2 of the head car through a turning mechanism 3.
[0035] like figure 2 As shown, the bogie 1 includes a frame 4, a suspension traction device 5, a wheel pair 6, a drive motor (not shown in the figure), a brake, etc., wherein, four drive motors are used to drive four wheels respectively, and four drive motors and the brake are fixedly installed on the mounting beams 7 on both sides of the frame 4, so that the arrangement is conducive to reducing the height of the floor surface.

The invention relates to a bogie suspension draw gear for a low-floor articulated railway vehicle. The draw gear comprises a swing bolster, primary springs, and secondary springs; and the swing bolster is connected with a railway vehicle body by a swing mechanism. In addition, the draw gear also includes two traction rods parallel to each other; the two traction rods are installed between two side beams of a frame; and one side, in a longitudinal direction of the railway vehicle body, of the swing bolster is connected with end beams of the frame by the two traction rods. According to the invention, the draw gear has a simple and compact structure and has light weight. Transmission of a traction force and a braking force during the vehicle operation process can be realized well; vertical, transverse, and longitudinal loads are carried; small-curve passing capability is improved substantially; and because of the overall flat structure, the floor height is reduced substantially. The swing bolster is connected with the frame by two parallel traction rods and thus a side winder torsion bar resistance effect can be realized by using the traction rods, so that the vehicle can move stable and the bogie structure can be simplified.
Description
technical field [0001] The invention relates to a rail vehicle bogie, in particular to a bogie suspension traction device installed under a low-floor articulated rail vehicle driver's cab, 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...
