AI Technical Summary

Technical Problem

In the existing technology, the unlocking speed detection device of the automatic differential lock of all-terrain vehicles cannot guarantee product consistency, resulting in inaccurate detection of the unlocking speed of the automatic differential lock.

Method used

A device for detecting the unlocking speed of an automatic differential lock in an all-terrain vehicle was designed. By combining a dial indicator chuck assembly with a CNC lathe, the automatic lock differential is fixed using a three-jaw chuck and a half-shaft gear plug. Combined with a pulley roller probe and a pointer-type dial indicator, the unlocking speed can be accurately detected.

Benefits of technology

It enables rapid fixing and accurate testing of automatic locking differentials, ensuring product consistency and testing efficiency, and meets the requirements for unlocking speed testing of automatic locking differentials, thus ensuring product consistency.
