Abstract: A shock-absorbing suspension device includes a mounting rod mounted on a wheeled vehicle frame, a wheel rod mounted on a vehicle wheel axle and forward of the mounting rod, a counteracting member pivotally mounted on the mounting rod and having forward and rearward ends forward of the wheel rod, a primary linking bar disposed to couple one of the forward and rearward ends to the wheel rod so as to permit swinging of the counteracting member, a cantilever arm extending forward from the mounting rod to terminate at a bearing end, and a force transmitting member disposed to couple the bearing end to the other one of the forward and rearward ends to thereby minimize the impact of shock on the mounting rod.
