Bistable operator module for actuator of speed reducer of e.g. electric or hybrid motor vehicle, has crowns respectively connected to studs emerging at case ends, where one crown is pulled back in elastic manner toward reference position

摘要

The module has a case (17) in which toothed crowns are mounted. The crowns are pulled back toward each other in an elastic manner, and include teeth (13, 14) axially extended and provided with asymmetrical complementary sections with respect to a point of each tooth. The crowns are respectively connected to studs (5, 10) emerging at ends of the case. One of the crowns is pulled back in an elastic manner toward a reference position. The crowns are fixed to outermost and innermost shell supports (2, 9) stacked with one another. A helical spring (11) is arranged within the innermost support.
