Abstract
A gear system for a mobile object may include: a first shaft unit configured to adjust a driving direction of a fuselage; a second shaft unit coupled to the first shaft unit and configured to retract the first shaft unit into the fuselage or extend the first shaft unit, retracted into the fuselage, from the fuselage; a driver configured to supply driving force through which the first shaft unit and the second shaft unit can move; and a power transmission unit configured to selectively transmit the driving force of the driver to one of the first shaft unit and the second shaft unit by coupling the driver to one of the first shaft unit and the second shaft unit.
Claims16
A landing gear system comprising:
- a first shaft device configured to adjust a driving direction of a fuselage;
- a second shaft device coupled to the first shaft device and configured to retract the first shaft device into the fuselage or extend the first shaft device from the fuselage;
- a driver configured to supply driving force to operate one of the first shaft device and the second shaft device;
- and
- a power transmission device configured to transfer the driving force of the driver to the one of the first shaft device and the second shaft device by coupling the driver to the one of the first shaft device and the second shaft device,
- wherein the second shaft device comprises:
- a first gear formed on at least a portion of an outer circumferential surface of a second shaft;
- a second gear spaced apart from the first gear and connected to the power transmission device;
- and
- a flexible drive transmission member configured to couple the first gear and the second gear.
A landing gear system, comprising:
- a first shaft device configured to adjust a driving direction of a fuselage;
- a second shaft device coupled to the first shaft device and configured to retract the first shaft device into the fuselage or extend the first shaft device from the fuselage;
- a driver configured to supply driving force to operate one of the first shaft device and the second shaft device;
- and
- a power transmission device configured to transfer the driving force of the driver to the one of the first shaft device and the second shaft device by coupling the driver to the one of the first shaft device and the second shaft device;
- a guide link configured to guide a path through which the first shaft device is retracted into, or extended from, the fuselage;
- and
- a fixing unit configured to fix the first shaft device to the fuselage while the first shaft device is retracted into the fuselage,
- wherein the fixing unit comprises a fixing pin protruding from at least a portion of the guide link, and
- wherein in a state in which the first shaft device is retracted into the fuselage, the fixing pin is inserted into and fixed to a fixing body provided in the fuselage.
A landing gear system comprising:
- a landing gear comprising a first shaft and a second shaft configured to rotate in different directions, wherein the first shaft is configured to change a driving direction of a fuselage, and the second shaft is configured to retract or extend the first shaft into or from the fuselage;
- and
- a driver configured to supply driving force to rotate one of the first shaft and the second shaft,
- wherein the driver comprises an electric motor configured to supply the driving force to the one of the first shaft and the second shaft,
- wherein a shaft device comprises:
- a first gear formed on at least a portion of an outer circumferential surface of the second shaft;
- a second gear spaced apart from the first gear and connected to a power transmission device;
- and
- a flexible drive transmission member configured to couple the first gear and the second gear.
