Abstract
A balance weight is formed into a columnar shape to extend in an axial direction of a spoke connecting a wheel hub and a rim of a spoke wheel, has an insertion recess extending over its entire axial length to open in its outer periphery, and is secured by crimping to the spoke to surround the spoke inserted into the insertion recess. A reduced section having a decreased outer diameter is provided on the balance weight at an end facing toward the wheel hub. Thus, the balance weights can be mounted to the adjacent spokes of the spoke wheel without interference therebetween.
Claims13
A balance weight formed into a columnar shape to extend in an axial direction of a spoke connecting a wheel hub and a rim of a spoke wheel, said balance weight comprising:
- an insertion recess extending over its entire axial length to open in its outer periphery, whereby the balance weight is adapted to be secured by crimping to the spoke so as to surround the spoke inserted into the insertion recess, and
- a reduced section having a decreased diameter at an end of the balance weight facing toward the wheel hub when crimped to the spoke.
A balance-correcting structure for a spoke wheel which comprises a wheel hub into which an axle is inserted, a rim on an outer periphery of which a tire is mounted, and a plurality of spokes connecting the wheel hub and the rim, wherein the spokes are disposed so that the spokes adjacent to each other in a circumferential direction of the rim cross over each other, the structure comprising:
- columnar-shaped balance weights individually mounted to rim-side ends of at least an adjacent two of the spokes to extend in an axial direction of the spokes;
- and
- each of said balance weights including a reduced section having a decreased outer diameter at an end at which the balance weights are closest to each other in order to avoid contact between the balance weights mounted to the adjacent spokes.
