    • A hollow bicycle rim includes a pair of side portions, an outer portion and a spoke attachment portion with a plurality of spoke openings. The side portions have ribs to form opposing tire supporting surfaces. The outer portion extends between the side portions. The outer portion includes a pair of annular inclined surfaces extending radially inwardly from the side portions with a curved connecting surface extending therebetween. The spoke attachment portion is rigidly coupled with the side portions and the outer portion. The inclined surfaces are preferably angled between three degrees and seventeen degrees. The outer annular portion preferably has at least one aperture, but fewer than half of the number of spoke openings. The side portions preferably have a pair of inner bent sections. A pair of spoke attachment sections with the plurality of circumferentially arranged spoke openings preferably have radial lengths larger than the spoke openings.
    • 中空自行车轮辋包括一对侧部,外部和具有多个轮辐孔的轮辐连接部。 侧部具有肋以形成相对的轮胎支撑表面。 外部部分在侧部之间延伸。 外侧部分包括从侧面径向向内延伸的一对环形倾斜表面,其间延伸有弯曲的连接表面。 轮辐连接部分与侧部和外部部分刚性联接。 倾斜表面优选地在三度和十七度之间成角度。 外环形部分优选地具有至少一个孔,但是少于轮辐孔数量的一半。 侧部优选具有一对内部弯曲部。 具有多个周向布置的轮辐孔的一对轮辐连接部优选地具有比轮辐孔大的径向长度。

    • A tire noise damper to be disposed in an annular tire cavity formed between a wheel rim and a pneumatic tire mounted thereon. The damper comprises an annular band-like body which is made of an elastomeric material and provided with at least one generally U-shaped cut oriented in a circumferential direction. The cutout formed by the at least one U-shaped cut forms a flap risen by a centrifugal force during running, and the remainder forms a base band to be put around a bottom of the wheel rim in an elongated condition. In order to reduce resonance of the air in the tire cavity in not only the fundamental mode but also the higher harmonic modes, the flap may have a relatively long length such that, when risen, a radially outer end portion thereof comes into contact with the radially inside of a tread portion of the tire. Further, the flap may be made of nonwoven fabric at least partially.

    • Wheel rim comprising two rim seats having different diameters, inclined outwards and extended axially outwards by two humps of small height, the rim seat of smaller diameter being connected axially on the inside to a bearing surface via a truncated conical portion and the rim seat of larger diameter being connected axially on the inside to the said bearing surface by a rib of small or zero height, whose axially interior wall has a generatrix that makes with the rotation axis an angle open radially and axially outwards and at the most equal to 30°, characterised in that the said rib, which has an axially inside wall of axial width at most equal to the axial width of the said second seat is provided circumferentially with at least two transverse grooves of small size.
    • 轮辋包括两个具有不同直径的轮辋座,其向外倾斜并且向外向外延伸两个小高度的凸起,较小直径的轮辋座通过截头圆锥形部分在内侧轴向地连接到支承表面,并且轮辋座椅较大 直径在内部轴向地连接到所述支承表面,该肋具有小或零高度的肋,其轴向内壁具有母线,该母线使旋转轴线径向和轴向向外并且最大等于30°, 其特征在于,具有至少等于所述第二座的轴向宽度的轴向宽度的轴向内壁的所述肋沿周向设置有至少两个小尺寸的横向槽。

    • A bicycle wheel rim used for mounting a plurality of spokes thereon includes spaced left and right annular tire retaining walls adapted for retaining a bicycle tire therebetween, and an annular spoke mounting wall. Each of the tire retaining walls has an inner edge proximate to a central point of the wheel rim, and an outer edge distal to the central point of the wheel rim. The spoke mounting wall interconnects the inner edges of the tire retaining walls, and has a central bridging portion with left and right terminating edges, a left corner block which interconnects the inner edge of the left tire retaining wall and the left terminating edge of the bridging portion and which is formed with a set of left spoke fastening holes, and a right corner block which interconnects the inner edge of the right tire retaining wall and the right terminating edge of the bridging portion and which is formed with a set of right spoke fastening holes that are staggered with respect to the left spoke fastening holes.
    • 用于在其上安装多个轮辐的自行车车轮轮辋包括适于在其间保持自行车轮胎的间隔开的左右环形轮胎保持壁和环形轮辐安装壁。 每个轮胎保持壁具有靠近轮缘的中心点的内边缘和远离轮缘的中心点的外边缘。 轮辐安装壁将轮胎保持壁的内边缘互连,并且具有具有左和右终止边缘的中心桥接部分,将左轮胎保持壁的内边缘与桥接的左终端边缘相互连接的左拐角块 并且其形成有一组左辐条紧固孔,以及右拐角块,其将右轮胎保持壁的内边缘和桥接部分的右终端边缘互连,并且形成有一组右轮辐紧固件 相对于左辐条紧固孔交错的孔。
