Car wheel ball bearing has brake force strain sensors in well defined brake shoe force application path with sliding spacer shims and raised rings around force application bolts

摘要

A car wheel ball bearing has a brake shoe and brake force strain sensors (12) on the fixed flange (2) that measure the length change in the flange due to the force flow from brake pad fixing holes (3. 4) to brake shoe with raised edges (6) to the holes and smooth shims to concentrate the force transfer through the bolts and fixing holes.
