Actuating unit for electromechanically operated disk brake for vehicle operates one brake pad directly, the other via caliper reaction force, has piezoelectric motor unit, actuating element

摘要

The actuating unit operates one brake pad (4) directly and operates the other brake pad (5) via the reaction force of the caliper (2). It contains a piezoelectric motor unit (6) for generating as rotation drive movement with high torque and an actuating unit with at least one actuating element for converting the rotary motion into translational motion.
