Monorail train coupling type bogie shaped like Chinese character 'mu'

Abstract

The invention discloses a monorail train coupling type bogie shaped like a Chinese character 'mu', and belongs to the field of monorail train bogie devices. The monorail train coupling type bogie shaped like the Chinese character 'mu' comprises two bearing frames, an elastic coupling shaft, two horizontal damping cylinders, two driving wheels, two driving motors, four air springs, four high lateral rolling wheels and four low lateral auxiliary wheels. According to the monorail train coupling type bogie shaped like the Chinese character 'mu', the rotation angle among compartments can be decreased, the flexibility in the train advancing direction is improved, therefore, a whole train has the smaller turning radius, wheeltrack abrasion is reduced, and the repair cycle and the service life ofthe bogie are prolonged. S-shaped swinging of the two bearing frames relative to the train advancing direction is significantly reduced, complete replacement of an anti-S-shaped damper and a transverse limiting stop is achieved, the train advancing steadiness and flexibility are significantly improved through the design, therefore, the curve passage capacity of the train is significantly improved,and the lowest speed per hour when the train passes through a small-radius road section is increased.

Description

technical field [0001] The invention belongs to the field of monorail train bogie devices, and in particular relates to a mesh-shaped connecting bogie for monorail trains. Background technique [0002] The bogie frame of the existing monorail trains is an overall structure similar to the Japanese-shaped Chinese character. The Japanese-shaped frame and the car body are connected by vertical shock absorbers, and the frame and the bolster are connected by anti-snake shock absorbers. , to buffer the torsional moment when the frame is snaking, and at least one zigzagging bogie must be installed at the front and rear ends of each train car, resulting in at least four zigzag steering frames for any two connected train cars frame, the total number of frames required is large, and the manufacturing and maintenance costs are high. [0003] On the other hand, the Japanese-shaped bogie itself is a rigid structure, and its radius of gyration along the track is relatively large, which wi...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the existing monorail train frame of Chinese character Japanese, its Japanese overall frame must be connected with the car body through anti-snaking shock absorbers to buffer the torsional moment when the frame is snaking; any two train cars connected to each other need at least Four sun-shaped bogies require a large number of frames, and the cost of manufacturing and maintenance is high; and the radius of gyration of the sun-shaped bogies is relatively large, which not only increases the degree of wear and tear on the wheels and rails, but also increases maintenance costs. The ability to pass through curves is limited, and the technical problem of restricting the improvement of driving speed and stability, the invention provides a mesh-shaped connecting bogie for monorail trains
