Embodiment Construction

[0043] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0044] Such as figure 1 As shown, a low-floor rail vehicle bogie 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 two carriages are respectively connected to the The bogie 1 is connected by a slewing mechanism 101 .

[0045]The bogie 1 includes a frame 2, a primary suspension device, a secondary suspension device, a traction device 3, a wheel set 4, a drive motor (not shown in the figure), a brake, etc., and four drive motors are used to drive four wheels 5 respectively. , four driving motors and brakes are respectively fixedly installed on the mounting beams 81 on both sides of the frame 2, and the driving motors and brakes are installed on the outside of the wheels 5, so that the arrangement is conducive to reduci...

Abstract

The invention relates to a pulling device of a bogie of a low-floor railway vehicle and a bogie. The pulling device comprises two pulling rod assemblies. Each pulling rod assembly comprises one or more pulling rods. One end of each pulling rod is connected with a swing bolster, and the other end of each pulling rod is connected with a central crossbeam of a framework. The two pulling rod assemblies are installed between two side beams of the framework and arranged on the two sides of the central crossbeam of the framework correspondingly. The pulling device of the bogie of the low-floor railway vehicle and the bogie are simple and compact in structure, and a floor can be lowered, so that people get on and get off the vehicle easily; and in addition, decoupling between two adjacent vehicle bodies can be achieved easily, and the riding comfort and the operating reliability are improved.

Description

technical field [0001] The invention relates to a bogie for a low-floor rail vehicle, and at the same time relates to a traction device installed on a low-floor articulated rail vehicle, belonging 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 device that can lower the floor surfac...
