Problems solved by technology

With this arrangement, as in the traditional scheme, when the bicycle is running, almost all the driving torque transmitted by the sprocket to the rim is transmitted to the inclined spokes, considering that the radially arranged spokes are basically unable to transmit torque. , with the result that in this type of wheel the spokes arranged on the opposite side of the sprocket run a greater risk of breaking

Embodiment Construction

[0018] exist figure 2 As in Fig. 3, parts corresponding to those previously described are denoted by the same reference numerals.

[0019] In the wheel 18 of the present invention, the number of spokes 28a of the first group is greater than the number of spokes 28b of the second group. In the illustrated form of embodiment, the spokes 28a are twice as numerous as the second set of spokes 28b. Preferably, the spokes 28a and 28b are divided into a plurality of triplets 30 equidistant from each other. Each triplet 30 includes two spokes 28a of the first group and a spoke 28b of the second group, the spoke 28b being arranged at an intermediate position between the corresponding two spokes 28a of the first group. The spokes 28a of each triplet 30 are preferably parallel to one another, while the spokes 28b of the triplet 30 lie in radial planes equidistant from the spokes 28a. Spokes 28a, 28b may be secured to hub 24 and rim 20 in any number of ways. From an aesthetic point of ...

Abstract

Spoked wheel for bicycle, comprising a rim (20), a hub (24), with a first and a second anchoring portion of the spokes (24a, 24b) and a plurality of spokes (28a, 28b) connecting the hub (24) to the rim (20), in which a first set of spokes (28a) is anchored to the first anchoring portion (24a) and a second set of spokes (28b) is anchored to the second anchoring portion (24b), characterised in that the spokes of one set (28a, 28b) are in a higher number than the spokes of the other set (28a, 28b).

Description

technical field [0001] The present invention relates to a spoked bicycle wheel. More precisely, the present invention relates to a bicycle wheel comprising a rim with first and second spoke fixing regions and a hub, and a plurality of spokes connecting the rim and the hub. The spokes are divided into first and second groups according to whether the inner ends of the spokes are fastened to the first or second fastening region of the spoke. Background technique [0002] The technical problem upon which the invention is based is that in certain applications the spokes of the first and second groups are subjected to different stresses. As a result, one set of spokes on the same wheel runs a greater risk of breaking than another set of spokes in use. [0003] The first solution to this problem is shown in Figure 1 of the accompanying drawings. This figure shows a rear wheel of known type mounted on a bicycle frame 10 with two wishbones 12, the lower ends of which have grooves,...
