ELECTROMOTIVE BRAKE ACTUATOR

摘要

The invention relates to an actuator (15) for the electromotive actuation of a parking or stop brake (12), especially of a private car. Said actuator comprises, downstream of the electric motor (22), a planetary wheel transmission (10) which is axially cascaded in a multi-stage manner and comprises a centering pin (29) which is radially mounted on the two front ends thereof and extends coaxially to the output shaft (23), on the radial overdefined bearing arrangement thereof. Respectively one planet carrier (38) comprising a pinion (30) is embodied, along the centering pin (29), as a sun wheel for the planet wheels (34) on the planet carrier (38) of the following transmission step (35).
