Problems solved by technology

[0003] Due to the low floor of the existing 100% low-floor urban rail vehicles, the space under the vehicle is limited, which limits the design of the vehicle bogies. In addition, the existing 100% low-floor urban rail vehicle bogies generally have small curves and poor passing capacity , The floor surface is too high, it is difficult to get on and off the car, and the traction device is bulky, etc.

Embodiment Construction

[0028] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0029] Such as figure 1 As shown, a low-floor articulated rail vehicle bogie is installed on a low-floor articulated rail vehicle, and a bogie is installed below the junction of every two carriages, and the two carriages are respectively connected to the bogie through a slewing mechanism 1 .

[0030] The bogie consists of a frame 2, two bolsters 3, two sets of traction rods 4, two sets of wheels 5, four driving motors, two sets of magnetic track brakes, two sets of axle bridges, eight primary springs, four secondary The four driving motors independently drive the four wheels, and a set of slewing mechanism 1 is installed on the two bolsters 3, and the two bolsters 3 are respectively installed in the middle of the two sets of wheels 5, and each set of traction rods The two ends of 4 are respectively fixedly connected with the bolster 3 and the ...

Abstract

The invention relates to a bogie frame for a low-floor hinged type railway vehicle and a bogie. The frame is composed of two side beams, a center crossbeam, two end beams and two installation beams. The two end beams are fixed to the two end portions of the two side beams. The two ends of the center crossbeam are fixed to the middle portions of the two side beams. The installation beams are fixed to the outer sides of the side beams. After being welded, the side beams, the center crossbeam and the end beams are of a flat structure overall. The whole structure of the frame is optimally designed, the whole frame is of the flat structure, the limited space between independent wheels can be fully used, the frame is reasonable and compact in structure and small in weight, the height of a vehicle body floor face is greatly reduced, and the use requirement of the 100% low-floor vehicle is met.

Description

technical field [0001] The invention relates to a rail vehicle bogie frame, in particular to a low-floor articulated rail vehicle bogie frame, which 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 because of their advantages such as flexibility, convenience, strong adaptability, short construction period, low unit comprehensive cost and operating cost, and low-floor urban rail vehicles Among them, the bogie is the most important structural component, and its structure and various parameters directly determine the stability of the vehicle and the comfort of the ride. [0003] Due to the low floor of the existing 100% low-floor urban rail vehicles, the space under the vehicle is limited, which limits the design of the vehicle bogies. In addition, the existing 100% low-floor urban rail vehicle bogies generally have small curves and poor passing cap...
