HYDRAULICALLY REGULATED ELECTROMAGNETIC ACTUATOR, AND LANDING GEAR FITTED WITH SUCH AN ACTUATOR FOR CONTROLLING SAME

摘要

An electromechanical actuator comprising an electric motor (11) for driving an output shaft (4) in rotation via a reduction gear (20) and passive regulation stage (30) allowing for control of the speed of rotation of the output shaft. A braking member is arranged between an output of the reduction gear and the output shaft to be driven, the braking member being arranged to ensure two different braking levels depending on the direction of rotation of the shaft. The braking member is of hydraulic type and comprises a paddle (33) for transferring fluid between two chambers (34, 35) under the effect of the rotation of the output shaft, transferred fluid passing through a selective drawing member (41) which, depending on the direction of rotation of the actuator, opposes two distinct resistances to the decantation of the fluid from one chamber to the other.
