Abstract
In a method for manufacturing a spoke unit, the continuous fiber reinforced plastic is led from a middle supporting portion to a first supporting portion along the front surface of the mandrel. Subsequently, the continuous fiber reinforced plastic is led from the first supporting portion to the middle supporting portion along the back surface of the mandrel. Subsequently, the continuous fiber reinforced plastic is led from the middle supporting portion to a second supporting portion along the front surface of the mandrel. Subsequently, the continuous fiber reinforced plastic is led from the second supporting portion to the middle supporting portion along the back surface of the mandrel.
Claims10
A method for manufacturing a spoke unit having at least three spokes, comprising:
- providing a mandrel for molding a spoke unit, the mandrel including supporting portions equal in number to the number of the spokes;
- winding a continuous fiber reinforced plastic around the mandrel;
- and
- molding the spoke unit by curing the continuous fiber reinforced plastic,
- wherein the winding includes
- leading the continuous fiber reinforced plastic from the supporting portion corresponding to a first one of the spokes to the supporting portion corresponding to a second one of the spokes along a front surface of the mandrel, the second one of the spokes being disposed opposite to the first one of the spokes, and
- leading the continuous fiber reinforced plastic from the supporting portion corresponding to the second one of the spokes to the supporting portion corresponding to the first one of the spokes along a back surface of the mandrel.

A method for manufacturing a spoke unit having at least three spokes, comprising:
- providing first and second mandrels each for molding a spoke unit, each of the mandrels including supporting portions equal in number to the number of the spokes;
- combining the first and second mandrels so that front surfaces of the first and second mandrels are oriented in different directions;
- winding a continuous fiber reinforced plastic around the mandrels;
- and
- molding the spoke unit by curing the continuous fiber reinforced plastic,
- wherein the winding includes
- leading the continuous fiber reinforced plastic from the supporting portion corresponding to a first one of the spokes to the supporting portion corresponding to a second one of the spokes along the front surface of the first mandrel, the second one of the spokes being disposed opposite to the first one of the spokes, and
- leading the continuous fiber reinforced plastic from the supporting portion corresponding to the second one of the spokes to the supporting portion corresponding to the first one of the spokes along the front surface of the second mandrel,
- wherein the spoke unit includes 2n+1 spokes, where n is a natural number, and each of the spokes is connected to a rim of a wheel at a middle connecting portion, and a first connecting portion and a second connecting portion disposed on either side of the middle connecting portion, each of the spokes including a middle rib connected to and extending from the middle connecting portion, a first rib connected to and extending from the first connecting portion and a second rib connected to and extending from the second connecting portion,
- wherein each of the mandrels has a middle supporting portion corresponding to the middle connecting portion of the spoke, a first supporting portion corresponding to the first connecting portion of the spoke, and a second supporting portion corresponding to the second connecting portion of the spoke for each of the spokes, and
- wherein when in the spoke unit, any one of the spokes is defined as a first spoke, two spokes each disposed opposite to the first spoke with the center of the spoke unit therebetween are defined as a second spoke and a third spoke respectively, the winding includes:
- a first winding process that leads the continuous fiber reinforced plastic from the middle supporting portion corresponding to the middle connecting portion of the first spoke to the first supporting portion corresponding to the first connecting portion of the third spoke along the front surface of the first mandrel,
- a second winding process that leads the continuous fiber reinforced plastic from the first supporting portion corresponding to the first connecting portion of the third spoke to the middle supporting portion corresponding to the middle connecting portion of the first spoke along the front surface of the second mandrel,
- a third winding process that leads the continuous fiber reinforced plastic from the middle supporting portion corresponding to the middle connecting portion of the first spoke to the second supporting portion corresponding to the second connecting portion of the second spoke along the front surface of the first mandrel, and
- a fourth winding process that leads the continuous fiber reinforced plastic from the second supporting portion corresponding to the second connecting portion of the second spoke to the middle supporting portion corresponding to the middle connecting portion of the first spoke along the front surface of the second mandrel.
