Electrohydraulic disk brake for providing e.g. service brake function, in vehicle, has right external tooth allowed to cooperate with helicoid screw, brake piston pushed via wear compensator, and support bottom transmitted by force

摘要

The brake has a main cylinder (11), and a brake piston (20) that carries a mobile shoe. A hydraulic chamber (13) is delimited in the main cylinder. A secondary chamber (22a) is delimited in a secondary cylinder (22) by a sleeve distributor (65). A right external tooth (72b) is allowed to cooperate with a helicoid screw (73) that is actuated by an electrical motor (43) for moving a drawer (90) along a translation axis (XX). The brake piston is pushed via an intermediate wear compensator (30), and a support bottom (81) is transmitted by force.
