(EN) ELECTRIC BRAKE ACTUATOR FOR A MOTOR VEHICLE
(FR) ACTIONNEUR DE FREIN ÉLECTRIQUE D'UN VÉHICULE À MOTEUR
Abstract
(DE)
Die Erfindung betrifft einen elektrischer Bremsaktuator (1) für ein Kraftfahrzeug, mit einem Aktuatorgehäuse (2), in dem ein Elektromotor (4) mit einer Motorwelle (19) und mit einem wellenfesten Ritzel (20) sowie eine Trägereinheit (6) und ein mehrstufiges Getriebe (7) aufgenommen sind, wobei das Aktuatorgehäuse (2) einen den Elektromotor (4) aufnehmenden topfartigen Gehäuseabschnitt (2a) mit einem Gehäuseboden (36) und mit einer sich in Axialrichtung (A) der Motorwelle (19) erstreckenden Gehäuseinnenwand (28) aufweist, wobei in dem Gehäuseabschnitt (2a) ein elastisches Dämpfungselement (29) angeordnet ist, das einen ersten Dämpfungsabschnitt (31) und mindestens einen sich in Axialrichtung (A) erstreckenden zweiten Dämpfungsabschnitt (30) aufweist, wobei der erste Dämpfungsabschnitt (31) zwischen dem Motorgehäuse (5) und dem Gehäuseboden (36) und der zweite Dämpfungsabschnitt (30) zwischen dem Motorgehäuse (5) und der Gehäuseinnenwand (28) angeordnet ist.
(EN)
The invention relates to an electric brake actuator (1) for a motor vehicle, having an actuator housing (2), in which an electric motor (4), with a motor shaft (19) and with a pinion (20) fixed to the shaft, a carrier unit (6) and a multistage transmission (7) are accommodated, wherein the actuator housing (2) has a pot-like housing section (2a) which accommodates the electric motor (4) and has a housing base (36) and a housing inner wall (28) extending in the axial direction (A) of the motor shaft (19), wherein in the housing section (2a) an elastic damping element (29) is arranged which has a first damping section (31) and at least one second damping section (30) extending in axial direction (A), the first damping section (31) being arranged between the motor housing (5) and the housing base (36) and the second damping section (30) being arranged between the motor housing (5) and the housing inner wall (28).
