Bicycle wheel with unitary side construction
A wheel having a longitudinal plane normal to an axis of rotation. The wheel has a rim with side surfaces on opposite sides of the longitudinal plane. A hub is concentrically disposed relative to the rim. Two unitary side elements are disposed on opposite sides of the longitudinal plane and are coupled to the rim and to end portions of the hub. Each of the unitary side elements has an annular sidewall, a flange portion, and a plurality of spokes that do not cross the longitudinal plane and that integrally interconnect the annular sidewall and the flange portion. An end portion of each spoke of the one side element is tied to the end portion of an aligned spoke of the other side element adjacent to the sidewall to restrict the tied end portions from moving away from each other.
Method and apparatus for manufacturing spokes
A method and a device are provided for manufacturing spokes from a wire material, in particular for at least partially muscle-powered two-wheeled vehicles. The spokes include a spoke shaft having at least two shaft sections. The shaft sections differ in at least one cross-section. For shaping the cross-sections, the wire material is reshaped at least in sections by means of a shaping tool. The relative position of the wire material relative to the shaping tool is varied in the axial direction during reshaping. For shaping the cross-sections in the two shaft sections the relative position of the wire material relative to the shaping tool is varied by way of different positioning movements.
