Background technology
At present, known self motorless railcar mainly contains that traditional chain transmission drives and advanced two kinds of ways of propelling of friction-driven.Chain transmission type of drive is to use the driven by motor sprocket rotation, and sprocket wheel drives along the chain of orbital arrangement and moves, thereby promotes the railcar motion.Its weak point is highly energy-consuming, the scene is seriously polluted, reliability is low etc.Friction driving way be by friction pulley and and the friction lever that links of car body between the frictional force that produced promote the railcar motion.Its weak point is that friction drive device is comparatively complicated.In order to guarantee normal pressure that friction-driven is required and adapt to the skew of bend that the whole deflection structure of wheel holding mechanism and drive system is absolutely necessary.The working face of friction driving roller and support roller covers friction material outside needing, the normal phenomenon that disengaging occurs between this friction material and driving wheel body.In addition, the friction lever working face need carry out roughening to be handled, and processing cost is higher.Be subjected to Effect of Environmental such as working temperature, humidity, the unstable properties of friction-driven.
Summary of the invention
In order to overcome existing chain transmission driving and friction-driven complex structure, poor reliability and the high deficiency of manufacturing maintenance cost, proposed a kind of based on the magnetic force coupling effect between fluctuation electromagnetic field and static magnetic field have structure and technology is simple, the reliability height such as makes and maintenance cost is low at the non-contact electromagnetic field wave driving device of advantage.
A kind of non-contact electromagnetic field wave driving device is characterized in that: be made up of drive rod, magnetic field row wave generating device; Wherein its working face of drive rod upper edge is with the formation mode permanent magnet of equidistantly arranging, permanent magnet pole outwards and the magnetic pole of adjacent permanent magnet opposite; Magnetic field row wave generating device is by one group of solenoid of equidistantly arranging, form with the current controller that links with it, wherein the solenoid pole orientation is vertical relative with the drive rod magnetic pole with driving direction, wherein current controller makes solenoid produce magnetic field row ripple, the amplitude of magnetic field row ripple and frequency controlled by Control current.
Magnetic field row wave generating device mainly is made up of DC power supply, power field effect pipe, driver and control unit etc.DC power supply provides required electric current, the control unit follow procedure passes through the driver drives power field effect pipe with the PWM principle, with the electric current of control flows through solenoid, make the magnetic field row ripple that produces required frequency and magnetic field intensity in the solenoid, this ripple will apply active force to the permanent magnet on the drive rod working face, thereby drive rod is advanced.The speed that drive rod advances is consistent with the velocity of wave of this magnetic field row ripple.
The utility model has been simplified the structure of the drive system of existing track logistics car by proposing new drive principle and corresponding implementation structure, has improved its reliability, has reduced the cost of producing and safeguarding, and is simultaneously, also more energy-conservation than traditional friction-driven.The utility model can be applicable to railcar and drives the field,
