A direct drive straddle gearless monorail bogie

Abstract

The invention discloses a direct drive straddle type monorail bogie without a gear box. The monorail bogie includes a frame, a traction device mounted on the frame, a foundation braking device, a vibration damping device, a stabilizing wheel, a guide wheel and a running wheel; The permanent magnet motors on the frame are directly connected, and the frame is equipped with a split type shaft box composed of an upper shaft box and a lower shaft box. The upper shaft box and the lower shaft box are detachably fixedly connected. Wherein the upper shaft box is fixed on the side beam of the frame for installing the foundation braking device. The invention utilizes the permanent magnet motor direct traction transmission technology, greatly simplifies the structure, reduces the weight, improves the transmission efficiency, improves the "green" ability and improves the dynamic performance of the vehicle.

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 transportation 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 en...
