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 structure complexity and the deficiency on reliability and cost, the utility model proposes a kind of technology based on the magnetic force coupling principle and simple in structure, the reliability height, the non-contact magnetic force driving device of low cost of manufacture.
First kind of scheme: a kind of non-contact magnetic force driving device is characterized in that: by motor, be connected in driving wheel on the motor, form with the discontiguous drive rod of driving wheel; Wherein said driving wheel outer circumference is embedded with a circle permanent magnet in the formation mode, and adjacent permanent magnet pole is opposite on the driving wheel; Be on the drive rod plane relative with the driving wheel outer rim formation mode arrange with driving wheel on the permanent magnet of permanent magnet polarity respective opposite, and adjacent permanent magnet pole is opposite on the drive rod.Maintain a certain distance between the outer circumference permanent magnet of driving wheel and the permanent magnet of drive rod opposite face, make the enough strong magnetic force coupling of generation between the two.Motor rotates the permanent magnet that drives on the driving wheel and rotates, the magnetic field that the permanent magnet that rotates on the driving wheel rotates, and this rotary magnetic field makes the permanent magnet on the drive rod produce active force, and drive rod is pushed, thus railcar is pushed.
Second kind of scheme: can adopt the belt-type drive scheme.Promptly with the driving wheel structure in first kind of scheme of driving pulley structure replacement.This scheme is further strengthened the magnetic force coupling effect, improves driving force, to adapt to the situation of heavy load.
Permanent magnet on above-mentioned driving wheel or the rotating band outer circumference evenly distributes by circumference, and quantity is even number; Permanent magnet on the above-mentioned drive rod equidistantly distributes, and quantity is even number.
In order to guarantee drive rod and driving wheel, or keep certain clearance between drive rod and the rotating band, can on drive rod or driving wheel or rotating band, flexible baffle ring be set, because actuating force provides by magnetic field, so the wearing and tearing of flexible baffle ring and miscellaneous part are little.
The utility model has been simplified existing driving system structure by proposing new drive principle and corresponding implementation structure, has improved its reliability, has reduced the cost of producing and safeguarding, simultaneously, driving force also is improved.The utility model can be used for railcar and drive the field.

Embodiment
Non-contact magnetic force driving device of the present utility model can be used for self motorless railcar.Be that example is specifically introduced the utility model to be used for railcar below.
Among Fig. 1, drive rod 1 is made for nonmagnetic substance, with the railcar one, but orbital motion.The embedded permanent magnet 2 of drive rod is distributed on the working face of drive rod equally spacedly.This permanent magnet pole points to outside the bar, and the adjacent permanent magnet magnetic pole is opposite.Driving wheel 5 is made for nonmagnetic substance, by the motor drives rotation, is and the embedded permanent magnet 4 of driving wheel of embedded permanent magnet 2 same models of drive rod that its magnetic pole is relative one by one with the embedded permanent magnet 2 of drive rod, and adjacent permanent magnet polarity is opposite on its working face.The embedded permanent magnet of this permanent magnet arrangement pitches and drive rod 2 is identical.Make 1 of driving wheel 5 and drive rod form suitable gap, when driving wheel 5 rotated, because the effect of magnetic force coupling effect, drive rod 1 was pushed, thus the dolly orbital motion.
Among Fig. 2, drive rod is identical with Fig. 1.Driving pulley 8 and driven pulley 9 are made for nonmagnetic substance.Driving pulley 8 is by driven by motor, makes rotating band 7 motions with the driven pulley 9 of same model.The quantity of the embedded permanent magnet 6 of rotating band is even number, and with embedded permanent magnet 2 same models of drive rod, and both linear array spacings are identical.The magnetic pole of the embedded permanent magnet 6 of rotating band is relative one by one with the magnetic pole of the embedded permanent magnet 2 of drive rod, and adjacent permanent magnet magnetic is opposite.Make 1 of rotating band 7 and drive rod form appropriate gap, when rotating band 7 motions, because the effect of magnetic force coupling effect, the drive rod bar is pushed, thereby makes the railcar motion.
Among Fig. 3, because the embedded magnet 2 of drive rod forms the relation that attracts each other with the embedded permanent magnet of driving wheel (band) naturally at opposite face.Especially at turning track place, consider that there is skew in the drive rod relative orbit, for guaranteeing to form suitable gap between driving wheel or rotating band and drive rod, can on the working face of driving wheel or rotating band, form flexible baffle ring 10, because actuating force is provided by magnetic field, so wearing and tearing are little between flexible baffle ring 10 and the drive rod.In like manner, flexible baffle ring 10 also can be attached on the drive rod, and two kinds of flexible baffle ring effects are identical.
Drive unit of the present utility model is distributed with a determining deviation along track when being applied to railcar, realizes the Continuous Drive of relay mode.In the part that railcar is turned, adopt the position to adapt to the skew that mechanism compensates drive rod, to guarantee the spacing of driving wheel or rotating band and drive rod.
