Abstract： |
The present invention relates to structural design of six pole mechanism knee joint with knee moment of force controlling device, it is characterized in that a knee moment of force controlling device is set on the hinge shaft of member (5) and (6), said device is composed of step-by-step motor, driving gear wheel on the motor shaft and controllable friction moment of force system, said system adopts left and right symmetrical structure with central line as axle, and said structure mainly includes screw with left and right helix at two ends, left and right spiral nuts, compression spring and friction conical body set on screw, the friction conical body is fixed with member (6), its external conical surface and internal conical surface of member (5) form conical surface friction. Advantages flexible in operation, good controllability etc. |
