摘要： A motor-vehicle lattice frame (T) is described here that includes a plurality of structural nodes (N1, N2) each having a central body (1) and at least one hollow arm (2, 3, 4, 30) protruding from the central body (1). The lattice frame (T) also includes a plurality of beam elements (5, 6, 11, 27) connected to each other by means of the hollow protruding arms (2, 3, 4, 30). The structural nodes (N1, N2) are made by an additive manufacturing technique and at least one arm (2, 3, 4, 30) of one of the nodes (N1, N2 ) has an end portion opposite to said central body (1) having a channel shape (C) with an open cavity both at a front end (12) of the arm (2, 3, 4, 30) and along one side (13) of the arm (2, 3, 4, 30).

摘要： A suspension device (1) of a motor-vehicle wheel includes a support member (2) of the motor-vehicle wheel connectable to the motor-vehicle structure by means of one or more suspension members (B1, B2), a brake disc (D) connected in rotation with the motor-vehicle wheel, a brake caliper (3) associated with the brake disc (D) and a brake disc cover (4). The brake caliper (3) is formed in a single piece with the support member (2) of the motor-vehicle wheel by means of additive manufacturing technology.
