MECHANICALLY COUPLED SYSTEM WITH VARIABLE LEVER ARM FOR TORQUE COUPLING AND DECOUPLING BETWEEN INPUT AND OUTPUT
First Claim
1. A selective torque transfer device comprising:
- an input shaft extending along an axis and connected to an input hub;
an output shaft extending along the axis and connected to an output hub moveable along the output shaft;
a slider biased in a centered position substantially in line of the center axis of the input hub, the slider being moveable to an eccentric position offset from the center; and
a link pivotally connecting the output hub to the slider, wherein displacement of the output hub towards the input hub moves the slider from the centered position to the eccentric position to create a centrifugal force about the slider and transfer torque to the output hub.

Abstract
A selective torque transfer device is provided to transfer torque between one rotating component and a decoupled non-rotating component. The torque transfer device has an input shaft that extends along an axis and is connected to an input hub. The input shaft and input hub rotate about the axis on which they extend. A slider is disposed within the input hub and is capable of moving in a direction transverse to the axis. An output shaft extends along the axis and is connected to an output hub. The output shaft and output hub rotate about the axis on which they extend when the selective torque transfer device is in the engaged position. A link pivotally connects the output hub to the slider. The input hub is configured to rotate about its axis to create a torque.

20. A method for operating a selective torque transfer device comprising:
in response to an engagement command and a desired output torque, displacing an output hub pivotally linked to an input hub to displace a slider away from a center of the input hub to permit torque transmission between the input and output shafts.
