Directly-driven straddling-type gearless single-rail bogie

Abstract

The invention discloses a directly-driven straddling-type gearless single-rail bogie. The single-rail bogie comprises a frame, a traction device, a basic braking device, a shock reduction device, stabilizing wheels, guiding wheels and walking wheels, wherein the traction device, the basic braking device, the shock reduction device, the stabilizing wheels, the guiding wheels and the walking wheels are installed on the frame. An axle of the walking wheel pair is directly linked with a permanent magnet motor suspended on the frame through a split coupling, a split axle box composed of an upper axle box body and a lower axle box body is installed on the frame, the upper axle box body and the lower axle box body are detachably and fixedly connected, and the upper axle box body is fixed to a side beam of the frame and used for installing the basic braking device. The direct traction transmission technology of the permanent magnet motor is utilized, in this way, the structure is greatly simplified, the weight is reduced, transmission efficiency is improved, and environmental-protection capacity and vehicle dynamics properties are improved.

Description

Technical field [0001] The invention relates to a direct-drive straddle-type gearbox-less monorail bogie, in particular to a monorail bogie adopting a new type of traction transmission technology for direct drive of a permanent magnet motor, and belongs to the technical field of bogies. Background technique [0002] The straddle-type monorail transportation line has a small footprint, low cost, low operating noise, good climbing ability (maximum gradient 60‰) and small curvilinearity (radius R≤50m), so the straddle-type monorail vehicle The seated monorail system is suitable for mountainous terrain and public transportation in cities, and has attracted more and more attention from the society. As the world's energy resources are becoming increasingly tense and the environment is deteriorating, in order to improve the natural environment and the sustainable development of mankind, all human activities should consider its "green" nature (ie energy conservation and environmental pro...

AI Technical Summary

Problems solved by technology

The straddle-mounted monorail bogies using traditional traction drive technology have disadvantages such as complex structure, heavy weight, low energy efficiency, high cost and difficult maintenance

[0005] Chinese patent application number CN20151041821.8 discloses a straddle-type monorail bogie, which only mentions that the gearbox and traction motor are longitudinally arranged, and the brake caliper is installed on the gearbox. Chinese patent CN201320368231.9 discloses a straddle Seated monorail and suspended monorail combined transportation type, but it does not specifically involve bogie structure and technical characteristics, etc.
