Abstract
A freewheel adjustable wheel of the present invention comprises: a rotary gear unit that is rotated by receiving power from a pedal part and is provided with a gear along the outer circumference thereof; a case part that supports the rotary gear unit to be rotatable; a clutch bearing that transmits the power to the case part when the rotary gear unit rotates in the forward direction; a clutch hub that rotates together with the rotary gear unit; clutch gears installed on the clutch hub and fixed to the case part; and a drive unit that supplies rotational power; and a moveable gear unit moved by means of the power of the driving unit.
Claims20
A freewheel adjustable wheel comprising:
- a rotary gear configured to rotate by receiving power from a pedal and equipped with a gear along an outer circumference thereof;
- a casing rotatably supporting the rotary gear;
- a clutch bearing installed between the rotary gear and the casing, wherein the clutch bearing is configured to transmit power to the casing when the rotary gear rotates in a forward direction;
- a clutch hub fixed outwardly of the rotary gear and configured to rotate together with the rotary gear;
- a clutch gear installed in series with the clutch hub and fixed to the casing;
- a driver fixed to the casing and configured to supply rotational power;
- and
- a moveable gear assembly configured to move by power of the driver, wherein the moveable gear assembly moves in a freewheel mode of being engaged with the clutch hub and a non-freewheel mode of being engaged with the clutch hub and the clutch gear at the same time.
A freewheel adjustable wheel comprising:
- a rotary gear configured to rotate by receiving power from a pedal and equipped with a gear along an outer circumference thereof;
- a shaft installed horizontally through the rotary gear and fixed to a frame;
- a cover casing having the rotary gear and the shaft installed through a center thereof, wherein the cover casing is rotatably installed;
- a fixed casing installed in a shape to shield an open portion of the cover casing, wherein rotation of the fixed casing is restricted;
- a clutch bearing installed between the rotary gear and the cover casing, wherein the clutch bearing is configured to transmit power to the cover casing when the rotary gear rotates in a forward direction;
- a clutch hub fixed outwardly of the rotary gear and configured to rotate together with the rotary gear;
- a clutch gear installed in series with the clutch hub and fixed to the cover casing;
- a driver fixed to the fixed casing and configured to supply rotational power;
- and
- a moveable gear assembly configured to move by power of the driver, wherein the moveable gear assembly moves in a freewheel mode of being engaged with the clutch hub and a non-freewheel mode of being engaged with the clutch hub and the clutch gear at the same time.
An exercise bike comprising:
- a frame supporting a saddle and a handle;
- a pedal installed on a rotatable disk installed on a side surface of the frame;
- a rotary gear configured to rotate by receiving power from the pedal and equipped with a gear along an outer circumference thereof;
- a casing rotatably supporting the rotary gear;
- a clutch bearing installed between the rotary gear and the casing, wherein the clutch bearing is configured to transmit power to the casing when the rotary gear rotates in a forward direction;
- a clutch hub fixed outwardly of the rotary gear and configured to rotate together with the rotary gear;
- a clutch gear installed in series with the clutch hub and fixed to the casing;
- a driver fixed to the casing and configured to supply rotational power;
- and
- a moveable gear assembly configured to move by power of the driver, wherein the moveable gear assembly moves in a freewheel mode of being engaged with the clutch hub and a non-freewheel mode of being engaged with the clutch hub and the clutch gear at the same time.
