AI Technical Summary

Technical Problem

In disc brake systems, stress concentration at the connection point leads to load changes at the stress concentration area. Existing technologies disperse stress concentration by changing the thickness or material of the retaining element, but this is costly.

Method used

A wide section is provided at the connection point. By forming a wide section in the rotation direction of the brake caliper, stress concentration is mitigated, and changes to the plate thickness and material of the retaining member are avoided.

Benefits of technology

It effectively disperses stress concentration, reduces abnormal noise and uneven wear, and does not increase costs.
