The invention provides a wide-base wheel. The wide-base wheel specifically comprises a main rim and an outer rim, the edge of the inner side end face of the axial outer diameter face of the main rim is provided with an extending first bevel edge, the outer rim is arranged on a first step on the outer diameter face of the main rim in a sleeving mode from one side of the outer side end face of the main rim, and the outer diameter face of the outer rim is provided with an extending second bevel edge. The outer rim is connected with an annular flange on the axial outer side end face of the main rim through a flange arranged on the inner diameter face of the outer rim and a connecting structure, and a tire bead seat used for installing a tire is formed between the first bevel edge and the second bevel edge. The inner diameter face of the main rim forms an inner cavity of the wheel, and the inner cavity serves as a space for installing a hub motor. The inner cavity of the wheel occupies themain position of the axial size of the wheel, and the middle of the wheel is not separated by other structures, so that a large-size high-power hub motor can be arranged in the inner cavity of the wheel through the structure. The invention further discloses a wide-base wheel assembly and an electric vehicle.
本申请提供一种宽基车轮,具体包括:主轮辋、外轮辋;所述主轮辋轴向外径面的内侧端面边缘处设置有伸出的第一斜边,所述外轮辋从所述主轮辋外侧端面一侧套在所述主轮辋外径面上的第一台阶上,所述外轮辋外径面设置为伸出的第二斜边,所述外轮辋通过外轮辋内径面上设置的凸缘与所述主轮辋的轴向外侧端面的环形法兰通过连接结构相互连接,在所述第一斜边和第二斜边之间形成用于安装轮胎的胎圈座;所述主轮辋内径面形成车轮的内腔,所述内腔作为安装轮毂电机的空间。该车轮的内腔占据了车轮轴向尺寸的主要位置,中间没有被其他结构隔断,这样的结构使该车轮的内腔能够装进尺寸较大的大功率轮毂电机。本申请还一种宽基车轮总成及电动汽车。
