AI Technical Summary

Technical Problem

Existing methods for measuring brake caliper clamping force are performed inside a temperature chamber, which affects measurement accuracy and is unsafe. Furthermore, the high cost of sensors increases operational complexity.

Method used

Design a brake caliper clamping force testing device. The clamping force is transmitted from inside the temperature chamber to the outside through a force transmission mechanism. The force is measured at room temperature using an external force measuring instrument to avoid the influence of temperature. The guide rod and guide groove stabilize the gap between the inner and outer tubes to ensure accurate transmission of clamping force.

Benefits of technology

It enables efficient, safe, and low-cost measurement of brake caliper clamping force under different temperature conditions, improving measurement accuracy and ease of operation, and is applicable to various types of brake calipers.
