摘要：A redundant linkage and sensor assembly which includes a sensor that enables indication of the magnitude and direction of forces applied to the linkage, while maintaining full mechanical strength and function of the linkage. The linkage includes an inner first tube and an outer second tube arranged to move in telescoping fashion, a spring being connected between the outer tube and the inner tube. Within the outer tube the inner tube is connected to a stop assembly also connected to the outer tube, which stop assembly limits movement of the inner tube with respect to the outer tube to a selected range. A position sensor is also connected between the two tubes within the second tube to provide a signal indicative of relative movement. Whereby the axial forces on the linkage are monitored as the signal from the position sensor is related to movement in a known way and movement is related to applied force through the spring in a known way. If the spring should fail, forces are still transferred through the linkage due to the stops limiting relative movement of the tubes.
