Torque starting rocker bar for motor vehicle, has contact element producing dampening effect by alternate adherence and sliding of element with respect to body to displace slide and plate around amplitude threshold value of displacement
Résumé
The bar has a rigid external plate (1) having an elongated shaped body and a large articulation (3) having large volume and less stiffness. A slide (6) is integrated in one of rigid internal cores (5, 7) and is displaced with respect to the plate (1) in a direction along a longitudinal direction, and a rubbing contact element (4) is disposed between the slide and the plate (1). The element produces a dampening effect by alternate adherence and sliding of the element with respect to the body for displacing the slide and the plate (1) around an amplitude threshold value of the displacement.
