The invention discloses a mechanical elastic wheel hinge set structure. The mechanical elastic wheel hinge set structure comprises an upper connecting piece body and a lower connecting piece body which are distributed diagonally, a spring is connected between the upper connecting piece body and the lower connecting piece body, the two sides of the spring are each provided with a set of middle connecting piece body, and the two ends of the upper connecting piece body and the two ends of the lower connecting piece body are fixed to the middle connecting piece bodies respectively. The middle connecting piece is composed of four middle hinges of the same structure, the protruding part of the upper connecting position of one middle hinge is embedded into the groove part of the lower connectingposition of the other middle hinge, the upper connecting hole and the lower connecting hole are coaxially aligned, and hinge bolts are installed in the connecting holes in the left side and the rightside of the middle connecting piece. The hinge set structure has the advantages of being simple in structure, easy to machine and manufacture, capable of being combined and arranged according to requirements and wide in application range; and secondly, the hinge set has a certain damping effect, so that vehicle vibration caused by road surface unevenness can be reduced, and the driving smoothnessof the vehicle is improved.
