Definitions

  • the present invention relates generally to remote-control toy vehicles, and more particularly, to a remote-control toy motorcycle.
  • a rudimentary conventional remote-control toy motorcycle includes a framework, a front wheel mounted to the front part of the framework, and a rear wheel mounted to the rear part of the framework.
  • the front and rear wheels are provided for supporting the framework, wherein the former is capable of steering and the latter can be driven by a power drive device for rotation to drive the motorcycle to move forward.
  • the steering mechanisms of the aforesaid patents are based on the gravity shift to usually require a larger turning radius while the front wheel is steered, such that their maneuverabilities are deficient.
  • U.S. Patent No. 5,709,583 disclosed a steering system for a radio-controlled wheeled vehicle toy, in which a servomotor instead of the rudimentary spring is used for controlling the turning of the front wheel.
  • the U.S. Patent No. 5,820,439 disclosed a gyro stabilized remote controlled toy motorcycle, in which a motor and a clutch, instead of the servo motor, are further used for controlling the steering of the front wheel to greatly enhance dexterity of the maneuverability.
  • the clutch set located internally swings outward and expands due to the centrifugal effect and then contacts against the internal sidewall of the flywheel of the freewheel set, such that the freewheel set is driven for high-speed rotation to generate gyroscopic effect and then to enhance the stability of the moving motorbike.
  • the primary objective of the present invention is to provide a remote-control toy motorcycle, whose maneuverability is stable and dexterous at the same time.
  • the foregoing objective of the present invention is attained by the remote-control toy motorcycle composed of a body, a front wheel, a rear wheel, and a power output device.
  • the rear wheel includes a fastening shaft; a wheel rim set for inserting the fastening shaft therethrough and for rotation driven by the power output device; a planetary gear set having a gear wheel and a plurality of planetary gears, the gear wheel having an axial hole located a center thereof for inserting the fastening shaft therethrough, the planetary gears engaging and circling the gear wheel; a unidirectional rotary member inserted through the space between the fastening shaft and the axial hole for actuating unidirectional converse rotation of the gear wheel that is forced by an external torque; a clutch set connected with the planetary gears for synchronic rotation and for expansion in high-speed rotation; and a flywheel set having a flywheel surrounding the clutch set for rotation actuated by the expansion of the clutch set, the flywheel having a plurality of cavities for receiving
  • a remote-control toy motorcycle constructed according to a preferred embodiment of the present invention is composed of a front body 10, a rear body 50, and a power output device 40.
  • the front body 10 includes a front frame 11.
  • a seat 12 is mounted to a top end of the front frame 11 for a rider (not shown) to sit thereon.
  • a front suspension 13 and a steering gear 14 are mounted to a front side of the front frame 11 and seat 12.
  • a front wheel 15 is mounted below the front suspension 13.
  • the rear body 50 is detachably connected with the front body 10 by that front frame 11 is engaged with the rear frame 51 by screws 18.
  • a rear suspension 53 and a rear wheel 60 are mounted to a rear end of the rear frame 51.
  • the power output device 40 includes a DC motor 41 or an engine (not shown) for driving a gear set 52 located beside the rear frame 51.
  • the driving power generated the DC motor 41 can be transmitted to a chain wheel 56 beside the rear wheel 60 via a rotary shaft 54 and a chain 55.
  • the rear wheel 60 further includes a unidirectional rotary member 68, a planetary gear set 70, a clutch set 80, and a flywheel set 90.
  • the rear wheel 60 further includes a left wheel rim 61, a right wheel rim 69, a fastening shaft 62, a plurality of bearings 64, and a wheel body 65.
  • the chain wheel 56 is mounted to an external side of the left wheel rim 62 and can be driven by a chain 55 for rotation.
  • a decorative brake disk 691 is mounted to an external side of the right wheel rim 69.
  • the fastening shaft 62 puts the left and right wheel rims 61 and 60 together by means of two fasteners 621 and two bearings 64.
  • the fastening shaft 62 After the fastening shaft 62 is mounted between the left and right wheel rims 61 and 69, the fastening shaft 62 is not rotated along with the left and right wheel rims 61 and 69 while they are driven by the chain 691 for rotation. In other words, the fastening shaft 62 remains still after mounted to the left and right wheel rims 61 and 69.
  • the unidirectional rotary member 68 is a unidirectional bearing or a ratchet or other industrial parts for transferring torque along one single rotary direction and for idling along the other rotary direction.
  • the unidirectional rotary member 68 is a unidirectional bearing, it can be a roller bearing, a shore bearing, a mechanical frictional bearing, or a mechanical locking bearing.
  • the planetary gear set 70 includes a gear wheel 71, three planetary gears 73, and a triangular frame 75.
  • the gear wheel 71 is received in a recessed portion 611 in the left wheel rim 61.
  • the gear wheel 71 is a circular disk having internal annular teeth 711 formed at an underside thereof and an axial hole 710 formed at a center thereof for allowing the gear wheel 71 to be fixed to the fastening shaft 62.
  • the three planetary gears 73 are mounted to an internal side of the triangular frame 75, which faces the gear wheel 71, and engaged with the internal annular teeth 711.
  • the triangular frame 75 is fixed to the left wheel rim 61 by three screws 751 and can be rotated along with the rotation of the left wheel rim 61. When the triangular frame 75 is rotated, the three planetary gears are driven to circle the gear wheel 71 that is not constantly rotatable.
  • the unidirectional rotary member 68 is mounted between the external side of the fastening shaft 62 and the sidewall of the axial hole 710 for actuating the gear wheel 71 to run along one single rotary direction. Specifically, as soon as the gear wheel 71 bears the torsional resistance of the three planetary gears 73, the unidirectional rotary member 68 drives the gear wheel 71 to rotate along a rotary direction converse to that of the planetary gears 73 to immediately release inertial impulse.
  • the clutch set 80 includes a clutch holder 82, three separable pieces 84, and an annular springy member.
  • the clutch holder 82 is sleeved onto one end of the fastening shaft 62, having a teeth portion 83 formed at a center thereof corresponding to the three planetary gears 73 for engaging the three planetary gears 73 and for rotation along with the same.
  • the three separable members 84 are tightly annularly mounted to the clutch holder 82.
  • the annular springy member 86 is a tension spring, surrounding the three separable members 84 for constricting and keeping the three separable pieces 84 tightly surrounding the clutch holder 82 while the centrifugal effect becomes weaker.
  • the flywheel set 90 includes a bushing 91 having an annular chamber, a main body 92 having a central chamber, a plurality of weights 95, and a flywheel cover 97.
  • the bushing 91 is mounted into the central chamber of the main body 92 for surrounding the three separable pieces 84, i.e. the three separable pieces 84 are located in the annular chamber of the bushing 91.
  • the main body 92 has a plurality of cavities 93 recessed toward the left wheel rim 61 and annularly arranged at a predetermined interval for receiving a plurality of weights 95 whose number is equal to or fewer than that of the cavities 93. In practice, the number of the weights 95 depends on the user's option according to the road conditions.
  • the flywheel cover 97 is screwed to an external side of the main body 92 for sealing the cavities 93 and preventing the weights 95 from falling off the cavities 93.
  • the rotary speed of the flywheel set 90 is still higher than what the power output device 80 transmits to the rear wheel 60 to enable the flywheel set 90 to generate gyroscopic effect to stabilize the whole remote-control toy motorcycle.
  • the gyroscopic effect for the stabilization becomes more noticeable.
  • the remote-control toy motorcycle usually has to immediately slow down the speed while turning, braking, or drifting at high speed, such that the separable members 84 should immediately return to the bushing 91 due to the weakening centrifugal effect to disengage from the bushing 91.
  • the separable members 84 disengage from the bushing 91 because the annular springy member 86 fails to constrict the separable members 84 in real time.
  • the flywheel set 90 still keeps inertial rotation for a short time, about one second and less, and then continue to return to the clutch set 80 to force the three planetary gears 73, which have run in low speed or stop rotation, to be actuated by the teeth portion 83 for high-speed rotation.
  • the unidirectional rotary member 68 mounted to the axial hole 710 enables the gear wheel 71 to do immediate converse rotation against the torsional impact of the three planetary gears 73 to release the short inertial impact transferred forward from the flywheel set 90, further preventing the three planetary gears 73 and the gear wheel 71 from damage resulted from excessive engagement with each other and then effectively lessening the stagger of the toy motorcycle.
  • the present invention when the present invention is operated, the user has to pick a proper number of the weights 95 beforehand subject to the road condition, e.g. if the weights 95 are more, the maneuverability will be more stable but less dexterous, and then put them into the cavities 93. Therefore, the present invention can adapt the remote-control toy motorcycle to various terrains, like cross-country or common flat roads, to reach both of the maneuverable stability and dexterity because of the optional number of the weights 95.
