Torque axle with composite structure for rear suspension of vehicle.

摘要

The twist-beam axle (10) comprises a cross-member (12) and a pair of trailing arms (14) of metal, each firmly connected to a respective end of the cross-member (12). The cross- member (12) has a hybrid structure with a central element (22) of composite material with a resin matrix reinforced with fibres and with a pair of lateral elements (24) of metal firmly connected to the central element (22). Once the cross-member (12) is manufactured, with the central element (22) and the two lateral elements (24) firmly connected to the central element (22), each trailing arm (24) is welded to a respective lateral element (24) of the cross-member (12).
