    • A wheel construction (10) includes a wheel rim (12) which in use, receives a tyre (13), the rim (12) being circular and having axially inner and outer portions (19, 20) each of which provides a flange (24) which in use provides a seat for a bead (26) of the tyre (23), and the wheel construction (10) including a mid-portion (29) between the inner and outer portions (19, 20), and side parts (30), connecting the mid (29) and outer portions (19, 20), the mid-portion (29) including a circumferential well (28) where the radius of the wheel rim (12) is a minimum, at least one of the side parts (230) including a plurality of curved regions (38, 39), the plurality of curved regions (38, 39) each being immediately adjacent to each other whereby the side part (30) is continuously undulate. Each curved region (38, 39) provides at least a further two circumferential wells (40, 41). For each adjacent two curved regions, there is an effective angle between a plane normal to the axis of the wheel and a line struck tangentially at a point of inflection between the two curved regions at a tyre side of the rim, of between 25° and 45°.
    • 车轮结构(10)包括轮辋(12),轮辋在使用中接收轮胎(13),所述轮辋(12)是圆形的并且具有轴向内部和外部部分(19,20),每个轮辋提供凸缘 24),其在使用中为轮胎(23)的胎圈(26)提供座椅,并且轮构造(10)包括在内部和外部(19,20)之间的中间部分(29) 连接中部(29)和外部部分(19,20)的部分(30),包括轮缘(12)的半径最小的周向孔(28)的中间部分(29)至少 所述侧面部分(230)中的一个包括多个弯曲区域(38,39),所述多个弯曲区域(38,39)各自彼此紧邻,由此所述侧面部分(30)连续起伏。 每个弯曲区域(38,39)至少提供两个周向孔(40,41)。 对于每个相邻的两个弯曲区域,在垂直于车轮的轴线的平面和在边缘的轮胎侧处的两个弯曲区域之间的弯曲点处切向地撞击的线之间存在有效的角度在25°和 45°。
