A method and apparatus for absorbing energy during a frontal collision of a vehicle, through the use of a front frame structure having main frame rails that include several deformable and non-deformable sections which are connected by selectively crushable junctures that are configured to predispose one or more of the junctures and sections to pivot selectively outward, rearward and upward, in a predetermined manner, during the collision. The front frame structure also includes an engine cradle, attached below the main frame rails, and having a pair of side rails that include forward and rear crushable junctures joined by non-deformable intermediate sections, with the crushable junctures of the main frame rails and engine cradle side rails being configured to predispose the intermediate sections of the engine cradle side rails to move downward and rearward during the collision.
A rail assembly for a vehicle includes a rail member extending longitudinally. The rail assembly also includes an insert disposed within and extending longitudinally along at least a portion of the rail member and having at least one curved section to provide load carrying capacity in the rail member.
A crossmember for supporting and limiting torsional forces of an engine unit relative to a mounting frame, particularly a vehicle body, wherein the crossmember is provided with at least one area or one device for introducing torsional forces into the crossmember.
An energy-absorbing underrun protection system for a vehicle. The energy-absorbing underrun protection system is comprised of a deformable construction adapted for deforming along a longitudinal axis to absorb crash energy. This deformable construction has a torque arm member extending substantially perpendicularly therefrom for receiving an impact load offset from the longitudinal axis and bending the deformable construction toward the impact load.
A vehicle chassis comprises two longitudinal side rails (10, 12). A first cross member (14) extends in a transverse direction between the front ends of the side rails (10, 12) and a second cross member (20) extends in a transverse direction between the central portions of the side rails. The chassis further comprises two secondary longitudinal members (22, 24) extending between the first cross member (14) and the second cross member (20), and the secondary longitudinal members are each connected to the side rails by means of a central support section (28, 30) which is longitudinally spaced between the first and second cross members (14, 20). The structure provides rigid support for the vehicle suspension and for a eye recovery (42), and crumples in a controlled way on frontal impact.
In a front body structure including a bulk head 25 for supporting the tip 24 of a hood 16 covering an engine room 18 of a motor vehicle 11 and fenders 27, 27 covering the upper part of front wheels 26, 26, the left and right ends 33, 34 of the bulk head 25, after bent backward of a vehicle body, are connected to the fenders 27, 27 to adjust the shape of the front of the vehicle body by the bulk head 25, and when viewed in a plan, V-shape portions are formed at connecting portions between the ends of the bulk head and the fenders so that each of the V-shape portions is covered with each of eaves 36 extended from the fender and bulk head.
