Abstract
A driving device for driving a wheel of an airplane in a direction same as that of a revolution of the wheel after landing, includes a revolution drive disc having a flat ring plate having an attachment portion adapted to attach on a side surface of a tire of the wheel; and a plurality of fins arranged on the ring plate. The plurality of fins is obliquely arranged on an outer side surface of the ring plate so that when the plurality of fins receives relative atmospheric air flow, a torque generated by the fins at a lower side of the tire in the direction same as that of the revolution of the wheel after landing is larger than a torque generated by the fins at an upper side of the tire in a direction reverse to that of the revolution of the wheel after landing.
Claims15
A driving device for driving a wheel of an airplane in a direction same as that of a revolution of the wheel after landing, comprising a revolution drive disc including:
- a flat ring plate extending along a whole periphery of the wheel and having an attachment portion adapted to attach on a side surface of the wheel, the ring plate being formed from rubber-based material;
- and
- a plurality of fins formed from rubber-based material and arranged on the ring plate at a predetermined pitch in a peripheral direction of the ring plate, the plurality of fins being obliquely arranged on an outer side surface of the ring plate so that when the plurality of fins receives relative atmospheric air flow, a torque generated by a part of the plurality of fins at a lower side of the tire in the direction same as that of the revolution of the wheel after landing is larger than a torque generated by a part of the plurality of fins at an upper side of the tire in a direction reverse to that of the revolution of the wheel after landing,
- wherein the ring plate is arranged to attach to the side surface of the wheel so that the revolution drive disc deforms in accordance with a deformation of the tire.
A driving device for driving a wheel of an airplane in a direction same as that of a revolution of the wheel after landing, comprising a revolution drive disc including:
- a pair of flat ring plates formed from rubber-based material and arranged parallel to each other in an axial direction of the drive disc with a predetermined space inbetween, the pair of ring plates extending along a whole periphery of the wheel and having an attaching portion adapted to attach to an outer side surface of the wheel, and
- a plurality of fins formed from rubber-based material and arranged between the pair of ring plates in a peripheral direction of the pair of ring plates at a predetermined pitch, the fins being obliquely disposed in a radial direction of the revolution drive disc so that when the plurality of fins receives relative atmospheric air flow, a rotational torque generated by a part of the plurality of fins at a lower side of the tire in the direction same as that of the revolution of the wheel after landing is larger than a rotational torque generated by a part of the plurality of fins at an upper side of the tire in a direction reverse to that of the revolution of the wheel after landing,
- wherein one of the pair of ring plates is applied with a rubber-based adhesive to attach to the outer side surface of the wheel so that at least one of the pair of ring plates is arranged to deform in response to a deformation of the wheel.
