摘要:
A connector is provided for connecting between a first and second structural members. The connector includes a load applying member which bears in use in a first direction against a crushable portion of the first structural member. A retainer retains the load applying member at an initial distance from the second structural member. A non-return mechanism can act in successive cycles of forced movement of the first structural member. When the first structural member is forcibly moved in a direction opposite the first direction the load applying member progressively crushes the crushable portion of the first structural member. When the first structural member is then moved in the first direction the retained location of the load applying member is moved in the first direction relative to the second structural member. In this way some or all of the play formed in the connection by crushing of the first structural member due to forced displacement in one direction, is taken up by the retainer during forced displacement of in the other direction. This enhances the energy absorbency of the connection during a large cyclical loading event such as an earthquake.
摘要:
The present invention is related to a nested crash box used as a passive safety component in vehicles, the content of which is obtained by connecting nested tubes of various lengths through the use of metal connecting techniques such as welding and hot forming for metal materials, and different adhesion techniques for composite materials. The present invention comprises a nested tube design which reduces the frontal acceleration of the passenger and stores the energy in a shorter crushing distance thanks to its stepped structure.
摘要:
Vehicle beams (1) are disclosed, the beams comprising a main elongation direction oriented along a central axis (a) and that is formed by a first material such that it comprises a higher strength zone (2) formed by the first material, the beam (1) comprising an enlarged portion (7) on which at least one dimension perpendicular to the axis (a) is increased relative to the rest of the beam. The beams include a lower strength zone (3) formed by a second material and that is located on said enlarged portion (7), the second material having a lower strength against intrinsic mechanical stresses than that of the first material; and the zones being located successively along the axis (a). Methods of manufacturing are also disclosed.

Le bras de suspension pour véhicule automobile comprend une première branche (1) destinée à être raccordée à un support de roue du véhicule, et une deuxième branche (2) destinée à être montée au châssis du véhicule. La première branche (1) est conformée de sorte que son profil général comporte, entre une zone de raccordement (Z1) au support de roue et une zone de raccordement (Z2) de la première branche (1) à la deuxième branche (2), une courbure (3) essentiellement comprise dans un plan vertical lorsque le bras est monté sur le véhicule.
