The two covers 64, 66 are provided with respective holes that fit with a slight friction on the final portion 50 of the elastic elements 46. The lightweight friction between covers 64, 66 and portion 60 is sufficient to keep roller 28 in axial direction on end portion 50 during device mounting. Once the assembly is completed, roller 28 resists extraction in axial direction from the side walls 14, 16 of the base structure 12.
El suministro de dos elementos rodantes 60, 62 montados rotativamente el uno con respecto al otro, y con el elemento rodante interior libremente rotativo sobre la porción final 50 del elemento elástico 46, permite eliminar completamente el riesgo de agarrotamiento del rodillo 28 con relación al elemento elástico. La estructura formada por los dos elementos rodantes 60, 62 es sustancialmente equivalente, desde el punto de vista cinemático, a un cojinete de rodillos en el cual el elemento rodante exterior 62 constituye el anillo exterior del cojinete y el elemento rodante interior 60 se comporta como una corona de elementos de rodillo.The supply of two rolling elements 60, 62 rotatably mounted with respect to each other, and with the freely rotating inner rolling element on the final portion 50 of the elastic element 46, allows to completely eliminate the risk of seizing roller 28 relative to the element elastic. The structure formed by the two rolling elements 60, 62 is substantially equivalent, from the point of view kinematic, to a roller bearing in which the rolling element outer 62 constitutes the outer ring of the bearing and the element rolling interior 60 behaves like a crown of elements of roller.
