The invention discloses a composite layer inner tube, and belongs to the technical field of inner tubes. The inner tube comprises an inflation ring, the inflation ring comprises an outer ring inner tube layer and an inner ring inner tube layer; the inner ring inner tube layer is a tire repairing rubber adhesive layer or a solid tire repairing rubber layer, an inflation cavity is formed in the inner ring inner tube layer, and an air valve is arranged on the inflation ring body. When the inflation ring is in an air leakage state, the annular tire repairing rubber layer can block and adhere to the air leakage hole of the inflation ring through air pressure in the cavity, the diameter of the inflation ring is matched with that of the inner face of the outer tire, the inflation ring is supported on the left inner face or the right inner face of the upper portion of the outer tire, and the inflation ring can support the outer tire in an inflated state.

    本发明公开了一种复合层内胎,属于内胎技术领域。它包括充气圈,所述充气圈包括外圈内胎层和内圈内胎层,内圈内胎层为补胎橡胶粘合胶层或固态补胎胶层,所述内圈内胎层内部形成充气空腔,在充气圈上设有气门。充气圈在漏气的状态下环形补胎橡胶层会通过空腔内气压堵塞并且粘合充气圈漏气孔部位,充气圈直径与外胎内面直径相吻合,充气圈支撑在外胎上部位左侧内面或上部位右侧内面,充气圈充气状态下能支撑外胎。
