Description

technical field [0001] The invention relates to the technical field of torque measurement, in particular to a torque measurement device. Background technique [0002] With the development of the domestic automobile industry, new models emerge in an endless stream, and automobile bench and road tests are becoming more and more important. Modern engines need to increase the speed to improve mechanical performance and efficiency, and torque is an important indicator of motor and engine performance, so high-precision and reliable torque measurement is required. [0003] The existing torque measurement methods mainly include the transmission measurement method of the resistance strain gauge type. The torque will cause a certain strain on the product to be tested, and this strain is proportional to the magnitude of the torque, so the corresponding torque can be detected through the resistance strain gauge that will undergo torsional deformation. When the product to be tested is ...
