Abstract
A driving wheel includes: a hub body disposed in a central region of the driving wheel; a plurality of spoke members inserted into the hub body and movable in a radial direction R of the driving wheel relative to the hub body; and link members each having one side coupled to one of the spoke members and the other side coupled to another spoke member disposed adjacent to the spoke member to which the one side of the link member is coupled. In particular, when the spoke members move in the radial direction R, the link members are rotatable about regions coupled to the spoke members.
Claims14
A driving wheel comprising:
- a hub body disposed in a central region of the driving wheel and having a plurality of first through-holes formed in a circumferential direction of the driving wheel;
- a plurality of spoke members movable in a radial direction of the driving wheel relative to the hub body, disposed in the circumferential direction, and inserted into the plurality of first through-holes formed in the hub body;
- and
- a plurality of link members disposed in the circumferential direction and each having one side coupled to one of the plurality of spoke members and other side coupled to another spoke member disposed adjacent to the spoke member to which the one side of the link member is coupled,
- wherein when the plurality of spoke members move in the radial direction, the plurality of link members are rotatable about regions coupled to the plurality of spoke members,
- wherein one side of each of two adjacent link members among the plurality of link members is coupled to one region of a spoke member disposed between the two adjacent link members,
- wherein the plurality of spoke members each comprises:
- a rod portion extending in the radial direction;
- and
- protruding portions extending from one side of the rod portion in a width direction of the driving wheel,
- wherein the plurality of link members has second through-holes, and the protruding portions are inserted into the second through-holes,
- wherein the hub body comprises:
- an extension portion extending from a central region of the hub body in the radial direction;
- and
- coupling portions protruding from the extension portion in the width direction, and
- wherein the link member has a third through-hole, and the coupling portion is inserted and coupled into the third through-hole.
