The invention discloses a spoke-free type hollow hub wheel and a bicycle. In the spoke-free type hollow hub wheel, a rim assembly comprises a rim, and a tire is arranged on the outer edge of the rim in a sleeving mode; the hub assembly comprises a left hub assembly and a right hub assembly, the left hub assembly and the right hub assembly are of a spoke-free hollow circular ring structure, and the left hub assembly and the right hub assembly are mutually matched and oppositely spliced and are fixed to the inner edge of the rim through a left bearing and a right bearing in a matched mode. Under the bearing of the left bearing and the right bearing, the left hub and the right hub serve as fixed parts of the wheel, and the tire and the rim assembly serve as rotating parts of the wheel. Through the technical scheme, the gravity center of the whole vehicle can be lowered, the unsprung mass is reduced, the axial and radial deformation and out-of-round probability of a wheel set is reduced, the crosswind influence is reduced, the aerodynamic mobility is enhanced, the energy loss is reduced, the trafficability and the transmission performance are improved, the situation that people or objects are wound into spokes to hurt or damage the vehicle is avoided, the structure is more visual, the assembly efficiency is high, and the cost is low. And maintenance is convenient.
本发明公开了一种无辐式空心轮毂车轮及自行车,无辐式空心轮毂车轮中,轮辋总成包括轮辋,轮胎套设于轮辋的外缘;轮毂总成包括左轮毂组件和右轮毂组件,左轮毂和右轮毂采用无辐式空心圆环结构,左轮毂与右轮毂之间相互配合相对拼接,并分别通过左轴承和右轴承配合固定于轮辋的内缘;在左轴承和右轴承的承接下,左轮毂和右轮毂作为车轮的固定部分,轮胎和轮辋总成作为车轮的转动部分。通过本发明的技术方案,可使整车重心降低、减轻簧下质量、降低轮组轴向和径向变形及失圆几率,减小侧风影响、增强空气动力流动性,降低能量损耗,提高通过性及传动性,避免人或物因卷入辐条而受伤或损害车辆,且结构更直观,装配效率高,检修方便。
