Permanent magnetism hybrid suspension system.
Background technique
Suspension type magnetic-levitation train is a kind of New Schemes track vehicle, the urban track traffic system as a kind of diversification
System can serve multilevel traffic, the supplement traffic of overhead grade separation etc. of tourist district gone sightseeing between visiting scienc spot, city building, rely on
Its own plurality of advantages is estimated will wide development and application prospect in China.Currently, existing suspension type monorail vehicle
To reach noise reduction purpose, travelling wheel mostly uses greatly rubber tire.And travelling wheel vehicle gravity itself, during actual operation
The abrasion of rubber tire are more serious, in turn result in system operation maintenance cost and increase.In consideration of it, as outstanding in realized using magnetic suspension mode
Hanging traffic can optimize the problem three kinds of approach: first is that by way of by vehicle suspension and noncontact driving, so that vehicle
Entirely without direct Mechanical Contact between track, mechanical shock and abrasion occurs to avoid rubber tire and track running face；Second is that
By way of suspension loss of weight, reduce the normal pressure between rubber tire and track, realizes and reduce mechanical shock suffered by rubber tire and rub
Resistance is wiped, achievees the purpose that the service life for increasing rubber tire, is suitable for slow traffic；Third is that passing through vehicle suspension realization and track
It is non-contact, it is driven by rubber tire side-contact type and realizes traveling, in this manner, rubber tire undertakes the task of driving and guiding,
But due to the self weight for not undertaking vehicle, so frictional force is also effectively reduced, plays the role of increasing the rubber tire service life, be also applied for low
Fast traffic.Currently, there are not actual suspension type maglev test car and engineering truck yet, the gentle penetrating judgment of great Zhai is handed in Israel and domestic southwest
The suspension type magnetic for awarding team's proposition floats scheme and is based on above-mentioned first way, and the suspension type magnetic for researching and developing multiple types is floating
Train is urgent and beneficial to diversification traffic and future transportation Mode exploration.
