FLEXIBLY MOUNTED DISC BRAKE ROTOR FOR PNEUMATIC, ELECTROMOTIVE, AND/OR HYDRAULIC DISC BRAKES.

摘要

A disc brake rotor includes at least one friction ring having a friction surface adapted for contact with a brake pad during braking, and an annular mounting portion by which the rotor is attachable to a hub. A connection permitting radial expansion and contraction of the friction ring relative to the mounting portion upon heating and cooling of the rotor is present between the friction ring and the mounting portion. This connection helps to resist cracking and subsequent failure of the rotor near its attachment to a hub.
