Claim Text:
1. A training machine of load force simulation, comprising: a housing; a damping unit being disposed inside the housing and comprising a press cylinder including a cylinder, a movable piston rod, and a pressure source to elevate the piston rod; a load cell disposed inside the housing; a controller coupled to the pressure source of the damping unit and the load cell in order to calculate the load value set by the load cell so that when the load value is beyond the allowable range, a signal would be transmitted back to the controller to control the damping force; a pulley system having the middle thereof connected to and elevating with the piston rod of the damping unit, having a middle movable pulley being arranged in the middle section thereof and at least one left movable pulley and one right movable pulley being arranged symmetrically on both sides of the middle movable pulley to keep the balance of the pulley system while elevating and lowering; at least one left fixed pulley with the axis thereof fixed inside the housing, arranged at a lower position between the middle movable pulley and the left movable pulley; at least one right fixed pulley with the axis thereof fixed inside the housing, arranged at a lower position between the middle movable pulley and the right movable pulley; a steel rope connecting the load cell with one end and rolling along partial circumference of the left movable pulley, then downward along partial of the left fixed pulley and upward along partial of the middle movable pulley; then downward again along partial of the right fixed pulley and upward again along partial of the right movable pulley, then finally reaching out the housing via an opening, forming a free end of the other end for the steel rope to stretch out; and a rope having one end thereof connecting to the free end of the steel rope; whereby the movable pulleys are equally bearing the load force from the rope in which when the loading is exceeding the load value of the load cell, the pulley system would be lowered and the damping force of the damping unit would be decreased, and when the loading is less than the load value of the load cell, the pulley system would be elevated and the damping force of the damping unit would be increased.
