Currently, existing suspension type monorail vehicle is to reach noise reduction purpose, travelling wheel mostly uses greatly rubber tire.And travelling wheel Vehicle gravity itself, the abrasion of rubber tire are more serious during actual operation, in turn result in system operation maintenance cost Increase.In consideration of it, as realized that suspension type traffic, consideration can optimize the problem by three kinds of approach using magnetic suspension mode: first is that By way of vehicle suspension and noncontact driving, so that entirely without direct Mechanical Contact between vehicle and track, to avoid Mechanical shock and abrasion occur for rubber tire and track running face;Second is that being reduced between rubber tire and track by way of suspension loss of weight Normal pressure, realize reduce rubber tire suffered by mechanical shock and frictional resistance, achieve the purpose that increase rubber tire service life, fit For slow traffic;Third is that it is non-contact with track by vehicle suspension realization, 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 the self weight due to not undertaking vehicle, so frictional force is also effective It reduces, plays the role of increasing the rubber tire service life, be also applied for slow traffic.Currently, Germany, Japan, the U.S., China carry out Research to suspension monorail, the existing project in the cities such as Chinese Guizhou Yellow fruit tree, Sichuan Chengdu, Binhai New Area in Tianjin Planning and construction, research optimization standard suspension train, be urgent to diversification traffic and future transportation Mode exploration And it is beneficial.
Summary of the invention
Based on the above-mentioned second way, the invention proposes a kind of suspension type monorails with Single electromagnet loss of weight construction Train system extends rubber tire service life its main feature is that rubber tire burden can be effectively reduced, and reduces maintenance workload.
Technical scheme is as follows:
A kind of suspension monorail system with Single electromagnet loss of weight construction, by suspension type rail box beam and passes through it On the bogie that is run on railway box girder track of rubber tire and the train body that is suspended on bogie constitute, feature exists In, be provided between bogie on the inside of box beam track Single electromagnet loss of weight construction: the loss of weight rail as made from high magnetic flux material 101 are placed in box beam track inside top, and loss of weight electromagnet 102 is arranged at the top of bogie face loss of weight rail position, subtracts with described Heavy rail constitutes electromagnetic coupling;The loss of weight controller 103 of control 102 operating current size of loss of weight electromagnet is also equipped on bogie; It is also equipped on bogie for monitoring the distance between 102 upper surface of loss of weight electromagnet and loss of weight rail 101 sensor 105 and monitoring Bogie relative motion speed and the velocity sensor 104 that signal is delivered to loss of weight controller 103.
Further, the train speed value and Distance-sensing that the loss of weight controller 103 is provided according to velocity sensor 104 The distance value that device 105 provides inputs the size of current of loss of weight electromagnet 102 to control.
Loss of weight controller controls the electric current of input loss of weight electromagnet according to velocity amplitude, and the speed the big, inputs loss of weight electromagnetism The electric current of iron is bigger, and loss of weight electromagnet is bigger by the suction of loss of weight rail, since loss of weight electromagnet is fixed on suspension type monorail column On the bogie of vehicle, so bogie is also bigger by upward pulling force, the rubber tire on bogie is to right on railway box girder at this time Answer the pressure of track will be smaller.Contrary circumstance: speed is smaller, and the electric current for inputting loss of weight electromagnet is smaller, loss of weight electromagnet by Suction to loss of weight rail is smaller, and the rubber tire on bogie will be bigger to the pressure of respective carter on railway box girder at this time.
When train speed is low, need the frictional force between rubber tire and track that train speed is driven to increase, so this In the case of kind, by the way of low degree loss of weight, such rubber tire is big to the pressure of track, is conducive to friction-driven.When train speed When spending high, in maintaining speed or be slowly increased the state of speed, the frictional force between rubber tire and track is smaller, then runs Resistance is smaller, is conducive to maintain speed in the case of low energy consumption, so in this case, by the way of big degree loss of weight, in this way Rubber tire is small to the pressure of track, is conducive to small frictional resistance operation, realizes low-power consumption and effectively increases the effect in rubber tire service life.
Loss of weight controller can also control input loss of weight electromagnet according to the distance between electromagnet and loss of weight rail value simultaneously Electric current because in the case where same size of current, distance value more under, the attraction between loss of weight electromagnet and loss of weight rail is got over Greatly, due to the irregularity of route, in actual moving process, the distance between electromagnet and loss of weight rail value are not fixed and invariable, If in the case that distance value becomes smaller, the electric current for inputting loss of weight electromagnet is very big, may be due to loss of weight electromagnet and loss of weight rail Between attraction it is excessive and cause train by picked up to bump against loss of weight rail failure occur, once so appearance distance value become Small the case where being more than permissible value, loss of weight controller can be interrupted to the input of the electric current of loss of weight electromagnet, until distance value be restored to it is fair Perhaps in range, then restoring current input.
Using structure of the invention, be conducive to the abrasion for alleviating suspension monorail rubber tire, while being also beneficial to reduce The power consumption of system operation, effectively improves the performance of suspension monorail.
