Technical Problem
[0003]目前的封闭轮一般内部为空心，外层通过多层碳纱直接进行成型，该类型的封闭轮不仅重量十分厚重，且由于内部是空心结构，故整体强度也很差
Benefits of technology
[0023]1、该一种骨架式超轻封闭轮的加工工艺整体封闭轮基于常规的骨架式碳纤维轮圈结构上增加了带内支撑片的碳片，一方面通过内支撑片配合支撑条来对成型时的外碳纱片起到足够且均匀的支撑作用，确保最终成型后的外碳纱片表面平整；另一方面也通过内支撑片来进一步提高整体封闭轮的强度，整体工艺流程设计简单巧妙，可以结合原有骨架式碳纤维轮圈的高强度特点，仅增加了内支撑片和碳纱的重量，整体重量比常规的封闭轮更加轻便且稳固，整体重量能够控制在0.87kg左右，相比常规的封闭轮的1.5kg的重量大大降低。

Abstract
The present application relates to the technical field of bicycle wheel rim, a processing technology of skeleton type ultra-light closed wheel, comprising the following steps: S1: producing a formed rim skeleton, the rim skeleton comprising a plurality of support strips uniformly distributed and pointing to the center of the circle in the length direction; S2: producing a carbon sheet, the carbon sheet comprising an outer carbon yarn sheet and an inner support sheet arranged in layers; S3: fixing the carbon sheet to the side of the rim skeleton, so that the inner support sheet is in contact with the support strip, and the outer carbon yarn sheet forms an outer closing plate of the closed wheel; S4: putting into a first mold for forming. The processing technology of the skeleton type ultra-light closed wheel is ingeniously designed, can be effectively optimized based on the skeleton type carbon fiber rim structure, and is overall light, stable and reliable.
