The invention discloses a tire inner supporting device, a wheel assembly and a vehicle with the wheel assembly. The tire inner supporting device comprises a supporting body, a threaded bushing and a locking structure. The plurality of support bodies are spliced end to end to form an annular support; the inner ring surface of the annular support body sleeves the outer side of the rim and is cohered with the rim, and the outer ring surface faces the inner side of the tire; the threaded bushings are embedded in the connecting positions of the two ends of the supporting body and connected through locking structures. The locking structures are in transition connection with the supporting body bodies through threaded bushings, so that the connected supporting body bodies and the rim are locked. The locking structure comprises a cushion block, a wedge-shaped block and a connecting bolt arranged at the connecting position of the supporting body, and locking pieces are installed between the connecting bolt and the wedge-shaped block and between the connecting bolt and the cushion block. And a connecting bolt sequentially penetrates through the locking plate, the cushion block, the wedge-shaped block and the two connected support bodies and is screwed with the threaded bushing. According to the scheme, it can be guaranteed that tire abrasion is reduced during air leakage driving, and the rim abrasion risk is eliminated in the conventional driving process.

    本发明公开一种轮胎内支撑装置、车轮总成及具有该车轮总成的车辆,包括支撑体本体、螺纹衬套和锁紧结构;多个支撑体本体首尾相接拼合成环形支撑体;环形支撑体其内环面套接于轮辋外侧与轮辋抱合,外环面朝向轮胎内侧;螺纹衬套镶嵌于支撑体本体两端的连接处,并通过锁紧结构形成连接;锁紧结构与支撑体本体通过螺纹衬套过渡连接,使各个相连的支撑体本体与轮辋锁紧;其中锁紧结构包括垫块和楔形块以及在支撑体本体连接位置设置的连接螺栓,连接螺栓与楔形块和垫块之间安装有锁片;连接螺栓依次穿过锁片、垫块、楔形块和相连的两瓣支撑体本体,与螺纹衬套旋合。上述方案能够保证泄气行驶时减少轮胎磨损,并且在常规行驶过程中消除轮辋磨损风险。
