Rear-axle for car, has non-linear vibration absorption device equipped with deformable cross-piece, mass, rail, Watt's linkage and annular body, where deformable cross-piece connects longitudinal arms with each other, and ring fixed on arms

摘要

The rear-axle (3) has a non-linear vibration absorption device (11) equipped with a deformable cross-piece (5), a mass, a rail, a Watt's linkage and an annular body. The deformable cross-piece connects longitudinal arms (4, 4') with each other. The mass rests on the rail and comprises an intermediate branch articulated on a left branch and a right branch that are connected to fixing studs, respectively. The mass is connected to the fixing studs via recalling units, respectively. A principal ring is fixed on the arms. The absorption device is placed in an inner side of one of the arms.
