Dynamic torque sensor can also be called torque sensor, torque speed sensor, non-contact torque sensor, rotation torque sensor, etc. Torque sensor is the detection of torsional torque perception on various rotating or non-rotating mechanical parts. Torque sensor converts the physical change of torque into an accurate electrical signal. Torque sensor can be used in the manufacture of viscometer, electric (pneumatic, hydraulic) torque wrench, it has the advantages of high precision, fast frequency response, good reliability and long life.

[0033] When the vehicle-mounted dynamic torque sensor based on CAN bus transmission is used, the transmission device is first connected to the power input end of the elastic body 401 through the coupling, and the transmission device is energized. At this time, the elastic body component 4 rotates at a high speed inside the housing 511 through the first bearing 402 and the second bearing 414. At the same time, the wireless receiving module 3 starts to supply voltage to the starting coil through the circuit modulation process. At this time, an oscillation circuit is formed between the starting coil and the resonant coil 413. The resonant coil 413 located on the positioning ring 404 receives the resonant voltage and starts to transmit the voltage to the wired collection mechanism 403 and the resonant coil 413 through the wire passing through the lead hole 406. The wireless transmitting module supplies voltage, and then the wired collection mechanism 403 collects the torque strain signal of the torque sensing change area of ​​the elastic body 401, and transmits the collected strain signal to the bottom cover component 2 through the wireless transmitting module. At the same time, the speed measuring gear ring 409 is in the central position of the photoelectric speed measuring sensor 302 to rotate and block the photoelectric signal. Then the strain signal and the speed measuring signal are transmitted to the wireless receiving module 3 for signal packaging, processing, conversion and modulation, and through the connector, it outputs the speed signal and torque signal in the form of CAN signal, which is conducive to efficient and stable signal transmission. When the device is in use, the dustproof plate 104 and the dustproof plate 505 can be used to prevent dust and block dust inside the housing 511, so that the device can be used in a relatively harsh environment, avoiding the influence of the harsh environment on the use of the first bearing 402 and the second bearing 414, and the stability of the sensor under high speed operation can be improved by lowering the moment of inertia of the first bearing 402 and the second bearing 414. When the device is installing the elastomer assembly 4, the elastomer 401 can be inserted into the interior of the monitoring ring 601 so that the elastomer 401 can be supported by the arc-shaped support platform 607, making the elastomer 401 more stable inside the shell 511. At the same time, the speed measuring gear ring 409 can be monitored by the monitoring probe 604. When the speed measuring gear ring 409 is worn after long-term use, the wear of the speed measuring gear ring 409 can be observed at the first time through the monitoring probe 604, thereby preventing the wear of the speed measuring gear ring 409 from seriously affecting the speed detection of the device.
