The invention discloses a mechanical wheel with a self-locking hinge structure, which comprises an inner rim, an outer rim and a hinge piece hinged between the inner rim and the outer rim, and a hinge locking structure is arranged between the hinge piece and the inner rim and/or the outer rim; the hinge locking structure comprises a double-partition-plate structure and a single-layer-plate structure, and the single-layer-plate structure is embedded in the double-partition-plate structure and hinged to the double-partition-plate structure through a fastening bolt. The ratchet wheel and a locking nut on the fastening bolt are of an integrated structure, and the ratchet wheel abuts against the outer side of the double-partition-plate structure; the pawl is located on one side of the ratchet wheel, and the hook claw end extends into the ratchet wheel; the elastic pressing piece is arranged on one side of the pawl and elastically abuts against the pawl, so that the claw hooking end of the pawl is meshed into the ratchet wheel. Compared with the prior art, the self-locking device has the beneficial effects that the corresponding ratchet wheel and the pawl are additionally arranged at the locking end of the fastening bolt at the hinged position, and the ratchet wheel is driven to rotate through lateral impact force generated in the turning process of a vehicle, so that the self-locking function is achieved.

    本发明公开了一种具有自锁式铰接结构的机械轮,包括:内轮辋和外轮辋,以及铰接于内轮辋和外轮辋之间的铰接件,铰接件与内轮辋和/或外轮辋之间设有铰接锁紧结构;铰接锁紧结构包括:双隔板结构和单层板结构,且单层板结构内嵌于双隔板结构之中并通过紧固螺栓相铰接;棘轮,与紧固螺栓上的锁紧螺母为一体式结构,并与双隔板结构的外侧相抵接;棘爪,位于棘轮的一侧其勾爪端延伸至棘轮内;弹性压片,设于棘爪一侧并与棘爪弹性抵接,使棘爪的勾爪端啮合至棘轮内。与现有技术相比本发明的有益效果是:通过在铰接处的紧固螺栓的锁紧端增加相应的棘轮和棘爪,并利用车辆在转弯过程中的侧向冲击力带动棘轮旋转,以实现自锁死功能。
