The invention relates to a manufacturing process for obtaining 6xxx-series aluminium alloy solid extruded products, comprising Si: 0.3-1.7 wt. %; Mg: 0.1-1.4 wt. %, Cu: 0.1-0.8 wt. %, Zn 0.005-0.7 wt %, one or more dispersoid element, from the group consisting of Mn 0.15-1 wt. %, Cr 0.05-0.4 wt. % and Zr 0.05-0.25 wt. %, Fe at most 0.5 wt. %, other elements at most 0.05 wt. % the rest being aluminium, having particularly high mechanical properties, typically an ultimate tensile strength higher than 400 MPa, preferably 430 MPa, and more preferably 450 MPa without the need for a post-extrusion solution heat treatment operation. The invention also concerns a manufacturing process for obtaining a bumper system in which is integrated a towing eye, said towing eye being made with said high mechanical properties aluminium alloys.

Manufacturing process for obtaining high strength solid extruded products made from 6XXX aluminium alloys for towing eye

A battery box for electric or hybrid motor vehicles, comprising a peripheral frame which has a generally convex polygonal shape, a bottom part and a top cover; the bottom part being joined to a lower surface of the peripheral frame, said peripheral frame comprising at least an aluminum extruded element, bent in a single direction in at least a position along the extrusion longitudinal direction according an angle wherein said bent aluminum extruded element at the said position presents at least two different inner radii of curvatures.

Battery box for electric vehicles

The invention relates to a bumper () for a motor vehicle, with a crossmember element () which has preferably two homogeneous outer sections () and a central section () differing from the outer sections (), wherein the central section () is displaced vertically downwards or upwards with respect to the two outer sections (). According to the invention, provision is made that the crossmember element () is constructed as an extrusion and in that at least one of the sections (to) has at least one additional element () arranged monolithically with the crossmember element ().

Bumper for a motor vehicle and method for its production

An attachment device for mounting a bumper cross-beam having a vertical front wall and a vertical rear wall spaced apart by a transverse wall onto a vehicle structure, the attachment device having a first end to be fixed to the vehicle structure and a second end configured to be attached to the bumper cross-beam, the attachment device being made from a hollow section profile, the periphery of which includes opposite side walls and substantially parallel opposite outer walls; the second end includes a flange, which can extend substantially beyond the vertical front wall after mounting the bumper cross beam, and on which a component is attached to the flange in front of said vertical front wall.

Attachment for bumper beam enabling additional function assembly

A device for mounting a bumper cross-beam onto a vehicle structure, the attachment means having a first end to be fixed to the vehicle structure and a second end designed to be attached to the bumper cross-beam, the attachment means being made from a hollow section profile, the periphery of which includes opposite side walls and substantially parallel opposite outer walls, wherein the hollow section profile includes opposite peripheral chambers, each peripheral chamber being at least delimited by one of opposite outer wall and an inner wall, which is substantially parallel to the outer wall and extends between the opposite side walls, wherein the inner walls are spaced apart from each other by a distance Hi, and the second end includes opposite double-walled flanges, which are spaced apart from each other by a distance H strictly greater than Hi.

Attachment means for mounting a bumper cross-beam onto a vehicle structure

Bumper crossbeam ('), having a plane of symmetry (Y) and globally oriented in a direction (T) perpendicular to the plane of symmetry (Y), comprising two attachment areas () symmetrically arranged with respect to the plane of symmetry (Y) and distant from each other by a distance D, said beam being designed to absorb the energy dissipated by a shock generated by a force substantially horizontal and oriented in a direction (L) perpendicular to said direction (T), made from a globally tubular body () with a monotonically varying nominal cross-section (Sn) over most of its length between said attachment areas (), except in two weakened areas (), which are symmetrical with respect to the plane of symmetry (Y), which are remote from the said plane of symmetry by a distance of between 0.10*D and 0.40*D, wherein the second moment of area about the axis (Z) perpendicular to the plane (L, T) is lower in the said weakened areas than expected from the nominal cross-section.

Tubular beam of an automotive structure having an improved impact behavior

A motor vehicle bumper with a crossmember () in channel form and a front element (), which is mounted in front of said crossmember and is in channel form, said crossmember and front element together forming a pedestrian protection system, characterized in that, in the assembled state, the front element () has a greater overall height (h) than the crossmember (), and the rear part (), which faces the crossmember, of the upper and lower wall regions of said front element are inclined from the horizontal towards the crossmember ().
