Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical testing technology, and in particular to a thickness testing table for adjusting shims of limited-slip differential locks. Background Technology
[0002] The differential lock is a crucial performance component of the drive axle, and the correct selection of the differential lock adjusting shim thickness is key to its performance. Traditional differential lock structures allow for external clearance adjustment, enabling external measurement and determination of the shim thickness. Newer differential lock adjustment mechanisms, however, place the shims internally within a confined space during assembly. This makes direct clearance measurement and inaccurate shim thickness selection impossible, necessitating trial assembly, which is labor-intensive and results in significant loss of precision due to repeated disassembly and reassembly. Therefore, there is an urgent need for a device that integrates the differential lock adjusting shims within the main reducer, allowing for external clearance measurement and resolving the issue of multiple trial assemblies.

By setting up a detection platform and cooperating with a first cylinder, the limited-slip differential lock is limited and fixed. Then, the output end of the second cylinder abuts against the bottom end of the limited-slip shim. Under the push of the second cylinder, the redundancy between the limited-slip shims can be quickly measured. The thickness of the adjustment shim is determined by the displacement of the displacement rod. The measurement result is accurate and the measurement process is simple.
