旋转机电致动器，特别是用于汽车的停车制动器

ROTARY ELECTROMECHANICAL ACTUATOR, PARTICULARLY FOR A PARKING BRAKE FOR A MOTOR VEHICLE
Abstract:
A rotary electromechanical actuator rotationally drives a spool member (20) for operating a flexible transmission means in a motor vehicle. The actuator comprises two speed-reduction stages connected in series. The first speed-reduction stage is a worm gear system with a worm (11) rotated by an electric motor (12) and a helical gear (13). The second speed-reduction stage is a planetary gear system with a central gear (14) rigidly connected to the helical gear (13), an internally toothed ring gear (15) fixed to a stationary casing (16), a series of planet gears (17) rotating on pins (18) attached to a planet carrier (19) rigidly connected to the spool member (20). The teeth of the helical gear (13) are coaxial and lie around and axially approximately level with the planetary gear system.
Abstract(Chinese):

旋转式机电致动器旋转地驱动用于操作机动车辆中的柔性传动装置的线轴构件（20）。 致动器包括两个串联的减速级。 第一减速级是具有由电动机（12）和斜齿轮（13）旋转的蜗杆（11）的蜗轮系统。 第二减速级是行星齿轮系统，其具有刚性地连接到斜齿轮（13）的中心齿轮（14），固定到固定壳体（16）的内齿环形齿轮（15），一系列行星齿轮 （17）在附接到刚性地连接到所述线轴构件（20）的行星架（19）的销（18）上旋转。 斜齿轮（13）的齿是同轴的，并位于行星齿轮系统的周围并轴向近似水平。
