Abstract
A motorizing system is provided for powering a wheel associated with a suspension of an aircraft, so that the aircraft can be moved around on ground. The motorized system includes a motor unit, a drive member that is structured to be secured to the wheel, and a clutch device that connects an output shaft of the motor unit to the drive member. The motor unit is structured to be secured to a sprung part of a suspension strut. A positive transmission occurs between the motor unit and the drive member.
Claims23
A motorizing system for powering a wheel associated with a suspension of an aircraft so that the aircraft can be moved around on ground, the motorizing system comprising:
- a motor unit;
- a drive member that is attachable to the wheel, the wheel having a tire;
- and
- a clutch device that enables movement of the motor unit relative to the drive member,
- wherein the motor unit is a sprung mass of a suspension strut of the aircraft,
- wherein the drive member is an unsprung mass of the suspension strut,
- wherein the clutch device moves the motor unit to and from an engaged position, in which an output gear of the motor unit is connected to the drive member, and a disengaged position, in which the output gear is separated from the drive member, and
- wherein a positive transmission occurs between the motor unit and the drive member.
A motorizing assembly for powering wheels associated with a suspension of an aircraft so that the aircraft can be moved around on ground, the assembly comprising first and second motorizing systems,
- wherein the first motorizing system powers a first wheel,
- wherein the second motorizing system powers a second wheel,
- wherein each of the first and second motorizing systems includes:
- a motor unit;
- a drive member that is attachable to the wheel, the wheel having a tire;
- and
- a clutch device that enables movement of the motor unit relative to the drive member to move the motor unit to and from an engaged position, in which an output gear of the motor unit is connected to the drive member, and a disengaged position, in which the output gear is separated from the drive member, such that a positive transmission occurs between the motor unit and the drive member,
- wherein the motor unit is a sprung mass of a suspension strut of the aircraft, and
- wherein the drive member is an unsprung mass of the suspension strut,
- wherein the suspension strut is shared by the first motorizing system and the second motorizing system,
- wherein the first and second wheels are coaxial, and
- wherein the motor unit of the first motorizing system and the motor unit of the second motorizing system are joined together.
