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

[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0030] Such as figure 1 As shown, a low-floor articulated rail vehicle bogie is installed under the driver's cab of the low-floor articulated rail vehicle and the head section carriage adjacent to the driver's cab, that is, it is installed at the head position. The bogie and the head section The car bodies of the carriages are connected by a slewing mechanism.

[0031] The bogie includes a frame 2, a bolster 3, a set of traction rods 4, two sets of wheels 5, four drive motors, two sets of magnetic track brakes, two sets of axle bridges, eight primary springs, four secondary Springs, etc., four driving motors independently drive four wheels, a set of slewing mechanism 1 is installed on the bolster 3 to connect with the car body, the two ends of the traction rod 4 are fixedly connected to the bolster 3 and the frame 2 respectively, and the bolste...

Abstract

The invention relates to a low-floor hinged rail vehicle steering frame structure and a steering frame. The structure consists of two side beams, two end beams and two mounting beams; the two end beams are fixedly welded with two end parts of the two side beams; the mounting beams are fixedly welded on the outer sides of the side beams; and the side beams, the end beams and the mounting beams are welded to form an integral flat structure. The whole structure of the structure is optimally designed, and the structure is the integral flat structure, so that the limit space between independent wheels can be fully used; and the structure is reasonable and compact in structure and light in weight, and can largely reduce the vehicle body floor surface height to satisfy 100% use requirements of low-floor vehicles.

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...
