Description

Technical field: [0001] The invention relates to a torque detection device, in particular to a clutch driven disk torque detection device. Background technique: [0002] The existing way to detect the torque of the clutch driven disc is to use a dual-range torque sensor for detection. By using the strain gauge electric measurement technology, a strain bridge is formed on the elastic shaft, and the torque of the elastic shaft can be measured by supplying power to the strain bridge. After the strain signal is amplified, it is transformed into a frequency signal proportional to the torque through voltage / frequency conversion. This method is costly, the range ratio is limited, and there is a mechanical gap, which often causes the signal to fail to return to zero. and other problems, the detection accuracy is low. Invention content: [0003] The object of the present invention is to provide a clutch driven disc torque detection device which is stable, reliable, high in precisi...
