摘要:
L'invention concerne procédé de fabrication d'une roue, la roue comprenant une jante périphérique (1), un moyeu central (2) et des rayons de liaison (8, 9) tendus entre la jante et le moyeu. Le procédé comprend les étapes de répartir les rayons (8, 9) selon deux groupes, un premier groupe de rayons (8) dépourvus de dispositif de mise en tension et un second groupe de rayons (9, 39, 49) ayant un dispositif de mise en tension, d'assembler les rayons à la jante et au moyeu, puis d'ajuter la tension des rayons à l'aide des dispositifs de mise en tension (9c) des rayons (9, 39, 49) du second groupe de rayons. L'invention concerne également une roue ayant un premier groupe de rayons (8) dépourvus de dispositif de mise en tension et un second groupe de rayons (9) ayant un dispositif de mise en tension.
摘要:
A spoked wheel of the type in which two flanges (9) formed on a hub (7) and a rim (2) are fastened and fixed by means of a number of spokes (1). In orderto permit a remarkable increase in the number of spokes so that the mounting operation does not become too complicated, a plurality of adjacent spokes are grouped into one block (b), said spokes belonging to such a block are fitted on the same side of the same flange and are made to extend substantially in the same direction so thatthey are fastened by means of corresponding nipples (5) to mounting holes (3) which, for each block, are formed on the same circumferential line (x or y) of said rim.
摘要:
A spoked rear wheel for a bicycle that may improve the rigidity of the wheel, while the weight of the spokes is restrained. The spoke rear wheel of the present invention comprises: a rim (10); a hub (20) having a hub axle (21), a first spoke attachment portion (22), and a second spoke attachment portion (23) spaced from the first spoke attachment portion; a first set of spokes (30) for connecting the rim to the first spoke attachment portion (22); and a second set of spokes (40) for connecting the rim to the second spoke attachment portion (23); the first set of spokes include a first spoke (31) and a second spoke (32); the second spoke includes a rim end portion (320) connected to the rim, a hub edge portion (321) connected to the first spoke attachment portion (22), a second central portion (322) connected to the rim end portion and hub edge portion, and having a second cross-sectional area. The first spoke (31) includes a rim end portion (310) connected to the rim, a hub edge portion (311) connected to the first spoke attachment portion (22), a first central portion (312) connected to the rim end portion and hub edge portion, and having a first cross-sectional area which is greater than the second cross-sectional area.

摘要:
The spoked wheel (10) comprises a rim (12) , a hub (14) and a plurality of spokes (16) which connect the rim (12) to the hub (14) and are connected to the rim by means of nipples (20) inserted in a corresponding plurality of drilled seats (26) in the rim (12). The rim (12) defines a concave outer cylindrical surface having a channel-like configuration with a bottom (12a) and a pair of flanks (12b) which extend from the opposing sides of the bottom (12a) of the rim (12). According to the invention, the rim (12) includes a first rim part (22) and a second rim part (24) which are separate from one another, wherein the first rim part (22) comprises a radially outer cylindrical portion (22a) forming the whole bottom (12a) of the rim (12) and the second rim part (24) comprises a radially inner cylindrical portion (24a) having the drilled seats (26) . Preferably, the first and second rim parts (22, 24) are detachably joined together by threaded connection members (28).
摘要:
The wheel includes an annular rim (20), a central hub and a plurality of spoke portions (22) running between the rim and hub, with each spoke having a width to thickness ratio of at least 2:1, with the spoke portions having an inside portion in fixed relationship to the hub and an outside portion in fixed relationship to the rim with the spoke portions extending radially outwardly between the hub and rim. An encircling member (84) is provided affixed to at least one of the inside and outside spoke portions defining an enclosed, continuous hollow annulus and including fasteners (86) within the hollow annulus for affixing said spoke portions to said encircling member.
