Straddle-type monorail train and traction suspension system thereof

Abstract

The invention discloses a traction suspension system of a straddle-type monorail train, including a steering frame, a traction mechanism arranged on the outer walls of both sides of the steering frameand used for driving the vehicle body to steer, a plurality of air springs disposed on the two side surfaces of the steering frame, a secondary lateral damper disposed at a middle position of the surface of the steering frame and for damping lateral vibration with respect to the vehicle body, and a secondary vertical damper disposed on the two side outer walls of the steering frame and for damping vertical vibration with respect to the vehicle body. Thus, since the installation position of the traction mechanism on the steering frame avoids the mounting space of the running wheels in the middle of the steering frame, the dismounting and maintenance can be conveniently carried out without the need for a vehicle. At the same time, the air springs, the secondary system transverse shock absorber and the vertical shock absorber are integrally arranged on the steering frame, and the vehicle body mounting seat is not required to be designed separately, so that the structure is more compact,and the vehicle body size and space occupancy are reduced. The invention also discloses a straddle-type monorail train, the beneficial effect of which is described above.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicles, in particular to a traction suspension system for a straddle-type monorail train. The present invention also relates to a straddle-type monorail train comprising the above-mentioned traction suspension system. Background technique [0002] The straddle-type monorail train has the advantages of large climbing ability, small turning radius, short construction period, and low cost. It has room for further promotion and wide application in China, and can effectively alleviate urban traffic congestion. [0003] The traction suspension device of the straddle-type monorail bogie mainly bears the load, traction force and braking force of the car body, and bears the impact of the bogie relative to the car body, and also meets the relative motion between the car body and the bogie. The traction suspension device is mainly composed of air springs, traction pins, traction beams, lateral stops,...

AI Technical Summary

Problems solved by technology

Because the traction device 100 is located in the center of the bogie, the existing traction suspension system is limited by the travel wheel 200 occupying the installation position of the components on the middle beam. Once a component is damaged, the damaged component must be replaced by a trolley

Moreover, the structure of the traction suspension system is complex, the traditional traction device 100 is generally a central pin traction mode, and the intermediate structure of the bogie frame is complex, which is not conducive to disassembly and maintenance

At the same time, air springs, lateral shock absorbers, vertical shock absorbers and other components are respectively designed with relevant car body mounting seats, which is not conducive to compact structure and will lead to excessive size of car body skirt

And this layout because the running wheel 200 occupies the installation position of the upper part of the middle cross beam, it makes it difficult to get off the car and connect it, and once the part is damaged, the damaged part must be replaced by a trolley
