Abstract
A brake assembly with multiple telescoping structures comprises: a rotatable part configured to be rotated by an actuator; a fixed part comprising an outer ball nut fixed to a housing; a rotatable and translatable part comprising an outer ball screw and an inner ball nut, wherein the outer ball screw is operably coupled with the outer ball nut through first rolling bodies, and the rotatable and translatable part is operably coupled with the rotatable part and is rotatable relative to the outer ball nut and axially translatable relative to the rotatable part and the outer ball nut simultaneously by rotation of the rotatable part; a translatable part comprising an inner ball screw operably coupled with the inner ball nut through second rolling bodies and configured to be axially translated relative to the inner ball nut by rotation of the inner ball nut to move a brake pad assembly.
