Abstract:
A bicycle wheel, in particular for racing and mountain bicycles, is provided which comprises a hub and a rim connected with by means of a plurality of radial elements. The radial elements are grouped in a first distribution, in which said elements are arranged on one side of the wheel, and a second distribution, in which said elements are arranged on the other side of the wheel, said first and second distribution connecting said rim to respective ends of said hub. The radial elements of said first distribution are connected to said rim in respective fixing seats which are disposed alternate, along said rim, to the fixing seats of the radial elements of said second distribution.
Abstract:
A bicycle rim includes side portions with an outer portion extending between the side portions to form a pair of outer corners, and a spoke attachment portion. The outer portion includes a pair of ridges spaced from the outer corners. The ridges preferably divide a pair of inclined surfaces. The side portions preferably include a pair of ground braking surfaces with a pair of sloping surfaces extending from the braking surfaces to a pair of outer side surfaces.
Abstract:
A rear bicycle wheel comprising a rim (20), a hub (24) carrying at least one sprocket (26), and a plurality of spokes (28a, 28b) which connect the hub (24) to the rim (20), in which one first set of spokes (28a) is anchored on one side of the hub adjacent to said sprocket (26), and one second set of spokes (28b) is anchored to one side of the hub further away from said sprocket (26), in which the spokes of the first set (28a) are greater in number than the spokes of the second set (28b).
Abstract:
A wheel of the bicycle wheel type includes a rim (200), a hub (10) with an axis (100) corresponding to the axis of the wheel, the hub including a left flange (11) and a right flange (12). The wheel includes an arrangement of rim-hub-rim connecting elements on at least one flange of the hub, which includes at least two sets of at least two rim-hub-rim connecting elements ((51-52; 53-54); (55-56; 57-58)), in the form of opposing spokes or rods, and in which the elements of each set are in planes situated on either side of the axis of the wheel and parallel to the axis.
Abstract:
A spoked wheel is described that uses flexible spokes having a termination on each end that couple with a rim using nipples. The flexible spokes are supported mid-span by a hub flange cradle that transfers torque from the hub to the rim via two sub-spokes. The hub flange cradle determines whether a sub-spoke is tangential or radial. A plurality of spokes may be used on each side of the wheel.
Abstract:
A spoked wheel assembly includes a wheel hub with right and left end flanges spaced apart from each other along an axis, a wheel rim around the hub, left spokes respectively coupled to the left end flange at left spoke mounting holes and to the rim at spoke mounting points, and right spokes respectively coupled to the right end flange at right spoke mounting holes and to the rim at other ones of the spoke mounting points. The right and left spokes are arranged alternately in one of a first spoke pair disposed along substantially parallel planes and a second spoke pair disposed along intersecting planes. Thus, the rigidity of the rim in the direction of the axis can be increased.
Abstract:
A bicycle wheel (10) comprising a rim (12), a hub (14), and a plurality of spokes (20, 22) having their outer ends fixed to the rim (12) and their inner ends fixed to the hub (14), the hub (14) having a left-hand anchoring portion (16) and a right-hand anchoring portion (18) for anchorage, respectively, of a set of left-hand spokes (20) and a set of right-hand spokes (22). The aforementioned spokes (20, 22) are grouped together in an even number of sets of three (24a, 24b) set at equal distances apart and comprising, alternately, two right-hand spokes (22) and one left-hand spoke (20), and two left-hand spokes (20) and one right-hand spoke (22).
Abstract:
A hub body of a spoked bicycle wheel comprises spoke attachment holes made in the hub body in a direction substantially parallel to a rotation axis of the hub body. Said holes comprise a first set of holes at a first radial distance from the rotation axis and a second set of holes at a second radial distance from the rotation axis, greater than the first radial distance.
