Description

Technical Field

[0001] The utility model relates to the field of automobile component testing, and more specifically to a half-axle torque testing and calibration device. Background Art

[0002] The measured value of the vehicle half-axle torque is the final output value of the power system. This parameter plays a very important role in the development of the vehicle's powertrain system. In the process of developing the powertrain system of an automobile product, it is necessary to perform a torque test on the vehicle half-axle. The torque test requires the strain value of the half-axle to be calibrated as a torsional moment value. By installing a strain gauge on the half-axle and calibrating the "strain-torque" to obtain the relationship between the half-axle strain and torque, the actual output torque of the half-axle can be measured by testing the half-axle strain.

[0003] China Patent Authorization Announcement No.: CN212931780U, provides a simple automobile half-axle torque test calibration device. This patented device is simple and can perform torque calibration without removing the half-axle, shortening the calibration cycle and improving the test efficiency. The use of the utility model device for torque calibration improves the test efficiency and has strong versatility. It can be widely used in the half-axle torque test calibration process of various vehicle models.
