Electromagnetically Actuated Coupling with Stable On and Off Switching

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a switchable clutch mechanism that connects a drive element and an output element. The clutch uses an actuator, preferably electromagnetic, to move a shifting element smoothly between different positions (start, middle, end), allowing the clutch to engage or disengage as needed. There is also an elastic element that pushes the shifting element towards its starting position, helping control the operation.

Patent Abstract

Switchable coupling (1) between a drive element (2) and a driven element (3), wherein the switchable coupling (1) comprises a coupling system (4) for a frictional and/or positive connection between the drive element (2) and the driven element (3) as well as a preferably electromagnetic actuator (5) and a switching member (6) in operative proximity to the actuator (5) and at least one elastic actuating element (10) arranged between the driven element (3) and the switching member (6), wherein the switching member (6) is movable continuously between a start position (7) via a middle position (8) to an end position (9), wherein the switchable coupling (1) in the middle position (8) of the switching member (6) has a different state (open or closed) than in the start position (7), and wherein the elastic actuating element (10) exerts a force on the switching member (6) in the direction of the start position (7) and wherein the actuator (5) exerts only forces on the switching member (6) in the direction of the end position (9), whose maximum value in each position exceeds the force value of the elastic...
