<p>Leaf spring (1), in particular for a suspension of a vehicle, of the multiple-leaf type, and preferably of the double-leaf type: a first, upper leaf (2) is provided at respective ends (8, 9) with corresponding eyelets (15, 16) for attachment to a vehicle, and is made of metal material, for example of steel, whereas a second leaf (3) which is connected to a lower surface (4) of the first leaf (2), is made of composite material, for example of plastic reinforced with fibre glass. The attachment eyelets (15, 16), which are produced by plastic deformation of the ends (8, 9) of the first leaf (2), are disposed entirely on one side of a longitudinal axis of symmetry (50) of the first leaf (2), on the side opposite the second leaf (3); the second leaf (3) extends longitudinally with its own respective end edges (13, 14) at least as far as the geometric centres of the eyelets (15, 16). Between the leaves (2, 3), in the vicinity of the eyelets (15, 16) and partially below the latter, there are interposed two friction buffers (21, 22) with a pre-determined thickness, which are coupled to the lower leaf (2) by means of a coupling tooth (27). Relative sliding of the leaves (2, 3) is prevented by a central bolt (20), whereas their relative rotation is prevented by a bracket (33) substantially in the shape of a "U", which is disposed in the vicinity of one of the eyelets (15). <IMAGE></p> |
