Definitions

  • the present invention relates to a stabilizing device for radio-controlled motorcycles, particularly for motorcycles used in the field of modeling and hobbies.
  • Such stabilizing devices are known from US 2006/0009119 or EP-A-1208892 .
  • flywheel which is mounted inside at least one wheel and allows to maintain the balance of the motorcycle by way of the gyroscopic effect produced by the rotation of said flywheel.
  • flywheel-based stabilizing devices are adapted for toy motorcycles, i.e., for motorcycles that travel at low speeds and are unsuitable to remain balanced on rough terrain.
  • Some devices for example the one disclosed in Italian patent application no. MI 2006A02239 , can however comprise mechanisms which allow the transfer of kinetic energy between the wheel and the flywheel.
  • Flywheel-based stabilizing devices which use mechanisms such as the one described above, though allowing motorcycle-like vehicles to travel at high speeds while remaining balanced even on rough terrains, suffer the drawback that it is not possible to control in any way the rotation of the flywheel during use of the motorcycle.
  • Another drawback consists in that the balanced condition of the motorcycle-like vehicle produced by the gyroscopic effect of the flywheel, when the wheel of the motor vehicle motorcycle is stationary, is a temporary condition; in fact since the kinetic energy accumulated by the flywheel can be depleted, the motorcycle-like vehicle tips once a time period long enough to allow the flywheel to stop has elapsed.
  • the aim of the present invention is to eliminate the drawbacks cited above by providing a stabilizing device for radio-controlled motorcycles in the field of hobbies and/or modeling, typically in a reduced scale, which allows the motorcycle-like vehicle to travel on two wheels at speeds on the order of even 80 km/h on any type of terrain, even on rough terrains.
  • an object of the present invention is to provide a stabilizing device for radio-controlled motorcycles which allows maximum control over the balanced condition of the motorcycle.
  • Another object of the present invention is to provide a stabilizing device for radio-controlled motorcycles which allows the motorcycle-like vehicle to maintain the balanced condition on its wheels without tipping for long periods of time even when the motorcycle is substantially stationary.
  • Another object of the present invention is to provide a stabilizing device for radio-controlled motorcycles which allows the motorcycle, if it tips, to return to the condition of balance on two wheels.
  • Still another object of the present invention is to provide a stabilizing device for radio-controlled motorcycles which is highly reliable, relatively easy to provide and at low cost.
  • a stabilizing device for radio-controlled motorcycles comprising a wheel of a motorcycle which is mounted so that it can rotate on a wheel rotation pivot and a flywheel which is mounted so that it can rotate on said wheel rotation pivot, characterized in that it comprises an electric motor which has a rotor which is rigidly coupled to said flywheel and a stator which is rigidly coupled to said wheel rotation pivot, said device further comprising a speed regulator for said electric motor which can be radio-controlled.
  • the stabilizing device for radio-controlled motorcycles comprises a wheel of a motorcycle (for example the rear wheel) which is provided with a wheel supporting structure 2 which is mounted so that it can rotate on a rotation pivot 3 and contains a flywheel 4, which also can rotate with respect to the pivot 3, said pivot 3 passing transversely through the flywheel substantially at the center.
  • the device 1 comprises an electric motor, preferably of the three-phase or rotary-casing type, provided with a rotor which is rigidly coupled to the flywheel 4 and with a stator 6 which is rigidly coupled to the pivot 3 and carries windings which are capable of inducing a rotation of the rotor if they are powered appropriately.
  • the rotor consists of at least one permanent magnet 5 or preferably a plurality of permanent magnets 5 which are fixed to the flywheel 4.
  • the flywheel 4 comprises a supporting element 8 which is substantially circular and is mounted so that it can rotate on the pivot 3 at the center of the circular supporting element 8.
  • a substantially annular flywheel mass 9 is rigidly coupled to the supporting element 8 and coaxial thereto and is fixed at the peripheral region 8a of the supporting element 8.
  • the supporting element 8 further comprises a substantially cylindrical recess 8b, which is coaxial to the pivot 3 and which partially accommodates, without direct contact, the stator 6 which is fixed to the pivot 3.
  • the recess 8b defines a cylindrical lateral surface 8c, on which the permanent magnet or magnets 5 are fixed for example by adhesive bonding.
  • the device 1 is electrically powered by at least one battery, not shown, and comprises a speed regulator 7 for the electric motor, which can be radio-controlled, for example by means of an optionally programmable radio control 20.
  • the speed regulator 7 is an electronic circuit which, for example by means of a microcontroller of the circuit, can be configured only to supply power to the windings or switch them off, i.e., to turn the flywheel 4 only at a maximum speed or to deactivate it. As an alternative, or in addition, the speed regulator 7 can also be configured to power the windings appropriately so as to obtain a plurality of speed levels at which the flywheel 4 is to turn about the pivot 3 of the wheel.
  • the device 1 can comprise a signal inverter, not shown, for generating an acceleration of the flywheel 4 which is of opposite sign with respect to the acceleration of the wheel by controlling the speed regulator 7.
  • This signal inverter which can be easily implemented electronically by the person skilled in the art, can be installed in an ordinary radio control 20, so that it receives the acceleration signal of the motorcycle imparted by the user by means of an adapted control lever 21, which is notoriously provided in known types of radio control, and transmits by means of the antenna 22 of the radio control a corresponding radio signal for accelerating the flywheel which is of opposite sign with respect to the motorcycle acceleration signal, using another channel which is different from the one of the acceleration signal.
  • the signal inverter can be mounted directly within the regulator 7 or in any case on the motorcycle, so that it can receive the radio signal for acceleration/deceleration transmitted by the radio control 20 and generate the corresponding signal for deceleration/acceleration of the flywheel 4, respectively.
  • a central flange 10 can be provided and keyed rigidly on the pivot 3 and has at least one through seat 10a, 10b for cables 11 for supplying the windings of the stator 6 which are connected to the speed regulator 7.
  • the rotating components of the device according to the invention are provided with internal bearings, so as to withstand high angular velocities.
  • the signal inverter does not send any acceleration/deceleration signal to the regulator 7, thus deactivating the electric motor.
  • the user acts on the control lever 21 of the radio control in order to send a suitable radio signal to the motor of the motorcycle.
  • the signal generated on the basis of the movement of the control lever 21 is acquired by the signal inverter, which determines whether the received signal is related to acceleration or deceleration. Accordingly, the signal inverter generates and sends to the speed regulator, by means of the antenna 22, a radio signal respectively for deceleration or acceleration of the flywheel.
  • the deceleration signal can optionally be only a radio command to no longer supply power to the windings of the stator, so as to make the flywheel idle.
  • the flywheel 4 is turned until it reaches its maximum angular velocity when the wheel is substantially motionless.
  • the flywheel 4 is idled or is gradually decelerated until it reaches a much lower speed.
  • the stabilizing device for radio-controlled motorcycles according to the present invention fully achieves the intended aim and objects, since it allows to ensure a condition of stable equilibrium even on very rough terrains, allowing maximum control over the speed of the flywheel.
  • the stabilizing device for radio-controlled motorcycles thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims; all the details may furthermore be replaced with other technically equivalent elements.
  • the materials used may be any according to requirements and to the state of the art.
