Suspension type monorail vehicle bogie and suspension type monorail train

Abstract

The invention discloses a suspension type monorail vehicle bogie and a suspension type monorail vehicle. The bogie comprises a framework, a main traction rod vertically penetrating through the framework and two sets of wheel drive devices mounted on the framework and symmetrically arranged on the two sides of the main traction rod in the longitudinal direction. Each wheel drive device comprises a power shaft, a non-power shaft and a drive brake mechanism, wherein the power shaft and the non-power shaft are rotationally mounted on the framework and longitudinally arranged at intervals, and the drive brake mechanism is in transmission connection with the power shaft. Hollow wheels are mounted at the two ends of the power shaft and the two ends of the non-power shaft. The main traction rod is connected with the framework through a secondary suspension device, the secondary suspension device comprises a main swing bolster fixedly connected with the main traction rod, auxiliary swing bolsters connected to the two ends of the main swing bolster in the longitudinal direction respectively and secondary springs connected to the two ends of the auxiliary swing bolsters in the longitudinal direction, and the secondary springs correspond to the axles in a one-to-one mode. On the premise that the bearing performance of the whole vehicle is not changed, compared with an original two-axle bogie structure, the load borne by each bearing of the four-axle bogie is halved, and thus the purpose of installing a small-wheel-diameter pneumatic tire is achieved.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a suspended monorail vehicle bogie and a suspended monorail train. Background technique [0002] The bogie of the suspended monorail train is located above the car body, the car body is suspended on the bogie, and the bogie runs in the box track beam. The running wheels of the suspended monorail train bogie mainly adopt rubber wheels, which are divided into solid wheels and pneumatic wheels. At present, there are two kinds of box-shaped track beams in the world's mainstream suspended monorail project with mature application performance. The first internal cross-sectional size: 1100mm (height) × 780mm (width); the second internal cross-sectional size: 1540mm (height) × 1550mm (width). The first type of box girder structure corresponds to the solid rubber wheel bogie, and the second type of box girder structure corresponds to the pneumatic rubber wheel bogie. [0003] For ...

AI Technical Summary

Problems solved by technology

[0003] For the first type of box girder structure, limited by the internal section size of the box track beam and the axle load requirements of the vehicle, the bogie can only use solid wheels. Compared with the use of pneumatic wheels, the use of solid wheels will affect the ride comfort of the vehicle. influences
