Embodiment Construction

[0047] refer to Figure 1-14 , discloses a disc wheel or double-sided cam 10 according to an embodiment of the present invention ( figure 1 ) method of manufacture.

[0048] Initially, a hub 12, a rim 14, a plurality of spokes 16, and a corresponding plurality of nipples 18 and possibly centering washers 20 are provided ( figure 2 , 7 ). The spokes 16 extend between the hub 12 and the rim 14 and are fixed, except as expressly stated below, by means of a nipple 18 and possibly a centering washer 20 , respectively, in a manner analogous to the case of manufacturing a spoked wheel. Spokes 16, nipples 18 and washers 20 form tensioning elements.

[0049] in more detail and refer to Figure 2-6 , in the embodiment shown therein, each spoke 16 is straight, ie extends along a rectilinear direction X or longitudinal axis X coincident with its tensioning direction, and at the end associated with the hub 12, the spoke 16 has a head 22 protruding perpendicularly to the direction of...

Abstract

A bicycle disc wheel or spoked wheel (10) is disclosed, comprising a hub (12), a rim (14) and at least one disc or spoke-type structural element (60) integral with the hub (12) and the rim (14), wherein said at least one structural element (60) is pretensioned. A process for manufacturing thereof comprises the sequential steps of providing a hub (12) and a rim (14), applying a compression on the rim (14) towards the hub (12) elastically deforming it, rendering at least one disc or spoke-type structural element (60) integral with the hub (12) and the rim (14), and removing the compression onto the rim (14) applied in step a).

Description

technical field [0001] The present invention relates to a bicycle wheel and a method of making the same. In particular, the invention relates to a bicycle disc wheel, also referred to simply as a double-sided cam or disc, and to a spoked wheel. Background technique [0002] Bicycle wheels with spokes made of composite material by injection molding or compression molding are known. For example, US 5,540,485 discloses a method of manufacturing a composite bicycle spoked wheel in which filaments of fibers are wound on an expandable mandrel, and in a mold the mandrel is expanded before the thermoset or thermoplastic resin matrix solidifies to Fiber prestressing. [0003] There are also known bicycle disc wheels comprising a spoked wheel and a pair of discs applied to the outside of the spoked wheel. The mechanical stress is borne by the spokes, while the platter is set exclusively for aesthetic and aerodynamic reasons and has no structural function. Contents of the inventio...
