| 20100052232 | FRICTION DEVICE FOR CONTROLLING FORCE, AND A FRICTION DAMPER COMPRISING SUCH A DEVICE - Friction device includes at least two members, one of which is mobile, or potentially mobile, in terms of relative displacement with respect to the other under the action of an external stimulus. The relative displacement is liable to cause the relative displacement of two friction surfaces subjected to pressing forces, so as to convert the external stimulus into a friction force and to thus control the displacement of the mobile or potentially mobile member. The pressing forces are produced by pre-stressing mechanisms and the members are able to act on the effects of the pre-stressing mechanisms so as to use the resultant effect of the relative displacement of the mobile or potentially mobile member to reduce the pressing forces. | 03-04-2010 |
