Description
Technical field
A kind of magnetic-force compressed friction drive device belongs to the technical field that propulsive effort is provided by tribology principle.
Background technology
At present, the known track logistics system that propulsive effort is provided by tribology principle is by track, form as the friction lever and the friction wheel system of a car body part.Wherein, the friction wheel system is by the drive wheel that connects with motor, uses with the drive wheel pairing, and the support roller of clamping friction lever and a series of spring system and revolute combine.When the friction lever with the vehicle body one entered into the friction wheel system, drive wheel and support roller were producing positive pressure under the effect of initial tension of spring on the friction lever driving surface, can produce the friction force that is used to drive when the driven by motor drive wheel rotates.At first, the predetermincd tension of existing friction wheel system is produced by spring system, and structure is complicated.For the ease of friction lever being imported the friction wheel system, initial tension of spring can not be excessive, so the friction force that is provided is limited; Secondly, owing to will make drive wheel produce positive pressure, support roller is absolutely necessary.This makes that also the friction wheel system architecture is complicated; Its three, in order to satisfy the driving requirement at the bend place, the friction wheel system need have whole swinging structure, this has further increased the complexity of friction wheel system.Higher structure complexity can cause the decline of friction wheel system reliability and the rising of productive costs.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, power-handling capability is strong, reliability is high magnetic-force compressed friction drive device.
First kind of form of the present invention: by motor, be connected in the friction force between friction driving roller, dependence and the friction driving roller on the motor and the friction lever that moves is formed; Wherein said friction driving roller circumferentially is embedded with the radially outside permanent magnet of a circle magnetic pole unanimity of the same name along wheel rim, and this permanent magnet produces attractive force to friction lever.The principle of utilizing permanent magnet and friction lever to attract each other, when friction driving roller contacts with friction lever, make the friction material layer between friction lever and the friction driving roller produce enough big squeese pressure, this pressure can directly produce friction drive and promote friction lever when motor rotates, and friction lever drives body movement.
Above-mentioned friction lever is a magnetic material.If opposite position also is embedded with and the oppositely directed permanent magnet of friction driving roller permanent magnet pole on the friction lever.Making two parts permanent magnet have stronger magnetic density, also is that both attractive forces are bigger, and the drive wheel that is produced is also big more to the pressure of friction lever.
Above-mentioned friction lever afterbody also can be provided with one section friction lever non-magnetic material section.When drive wheel drive friction lever moves to the friction lever rear, will enter non-magnetic material friction lever section.Because non-magnetic material friction lever section and friction lever face of joint are the domatic face, make the drive wheel permanent magnet break away from magnetic area gradually, suction fades away, thereby the pressure of friction material layer is faded away, and friction drive also disappears smoothly.This domatic structure has improved the stationarity of the process that drives.
Second kind of form of the present invention: can adopt the belt-type drive scheme.Promptly with the friction-driven wheel construction in first kind of scheme of friction-driven belts wheel construction replacement.The other technologies scheme is similar.
The beneficial effect of patent of the present invention is that the friction driving roller system architecture is simplified, thereby has improved its reliability, effectively reduces maintenance cost.Another direct benefit makes manufacturing process be simplified exactly, has saved material, and manufacturing cost is descended.In addition, because the strong magnetic action of strong permanent magnet material has improved effective positive pressure, thereby improved the power-handling capability of friction wheel system.

Number in the figure title: 1. friction lever, 2. friction lever permanent magnet, 3. friction material layer, 4. drive wheel permanent magnet, 5. friction driving roller, 6. friction-driven belts, the 7. embedded permanent magnet of rotating band, 8. driving pulley, 9. driven pulley, 10. non-magnetic material friction lever section, 11. friction lever sense of motions, 12. drive wheel sense of motions.
The specific embodiment
Among Fig. 1, friction lever 1 is made by magnetic material or is made of the embedded permanent magnet of non-magnetic material, and the magnetic pole unanimity of the same name of the permanent magnet in the friction lever 1 is towards the wheel outer rim of friction driving roller 5.Friction driving roller 5 is made the outer bigger flexible friction material layer 3 of friction coefficient that covers for non-magnetic material, be embedded in permanent magnet at friction material layer 3, permanent magnet magnetic pole of the same name along drive wheel radially outward, and is and opposite with the magnetic pole of relative friction lever permanent magnet 2, makes it be the state of attracting each other.As friction lever is that magnetic material is made, and can save friction lever permanent magnet 2.Because the magnetic attraction effect, make the friction material layer 3 that is clipped in 1 of drive wheel permanent magnet 4 and friction lever produce squeese pressures, promptly on friction lever 1 running surface, produce pressure.When friction driving roller moves, drive the friction lever motion, thereby drive the rail vehicle motion.
Among Fig. 2, friction lever 1 is made by magnetic material, perhaps is further to improve magnetic flow, can embedded permanent magnet, and this permanent magnet like pole is towards friction-driven belts 6.Driving pulley 8 and driven pulley 9 are made for non-magnetic material.Friction-driven belts 6 is to be with synchronously, and it is opposite with friction lever permanent magnet 2 relative magnetic pole magnetic that friction-driven belts is embedded in permanent magnet 7, makes it be the relation that attracts each other.Friction lever and friction-driven interband produce squeese pressure.Motor makes driving pulley 8 rotations, and driving pulley 8 drives driven pulley 9 and rotates, and makes synchronous band motion.Since the effect of friction force between rotating band and friction lever, the friction lever motion, thus drive the rail vehicle motion.
Among Fig. 3, it is identical with Fig. 1 that friction-driven wheel construction and friction lever bury the magnetic mode, at friction lever 2 afterbodys one non-magnetic material section arranged, and when friction driving roller 5 rotations, friction lever 1 will move.When friction lever will be deviate from friction driving roller, with the non-magnetic material friction lever section 10 at engaging friction bar magnetic sections rear portion.Because two bar section face of joints are the domatic face, make the embedded permanent magnet of friction driving roller break away from magnetic area gradually, suction fades away, thereby the pressure of friction material layer is faded away, and friction drive also disappears smoothly.This domatic structure has improved the stationarity of the process that drives.
