Abstract
A bicycle wheel includes a first panel member including a first rim portion for mounting a tire, a first hub mounting end connected to a hub, a first spoke portion for connecting the first rim portion and the first hub mounting end, a second panel member having a second rim portion for mounting the tire, a second hub mounting end connected to the hub, and a second spoke portion for connecting the second rim portion and the second hub mounting end, wherein the bicycle wheel is formed by joining the first panel member and the second panel member together such that the first panel member and the second panel member are symmetrical to each other about a line passing through the hub and the rim.
Claims7
A method of manufacturing a bicycle wheel, the method comprising:
- forming a first rim portion, a first hub mounting end, and a first spoke portion on a first panel member by press molding;
- forming a second rim portion, a second hub mounting end, and a second spoke portion on a second panel member by press molding;
- forming a first clinching portion and a second clinching portion, which each protrude to a side, by bending the first panel member and the second panel member;
- forming a rim with the first rim portion and the second rim portion by joining the first panel member and the second panel member together, mounting a hub to be coupled to the first hub mounting end and the second hub mounting end, and forming a spoke including the first spoke portion and the second spoke portion between the rim and the hub;
- forming a first reinforcing portion, which is spaced apart from the first rim portion, in a state in which the first clinching portion is formed by bending the first panel member;
- and
- forming a second reinforcing portion, which is spaced apart from the second rim portion, in a state in which the second clinching portion is formed by bending the second panel member.
