Abstract
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.
