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.
A vehicle chassis comprising two longitudinal side rails (10, 12) each having a central portion (10a, 12a) and a front portion (10b, 12b), a first cross member (14) extending in a transverse direction between the side rails and a second cross member (20) extending in a transverse direction between the central portions of the side rails, wherein 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, characterized in that the front portions (10b, 12b) are arranged in use to be higher than the central portions (10a, 12a) and the first cross member (14) extends between the front ends (10d, 12d) of the side rails and is arranged to be, in use, below the front ends (10d, 12d) of the side rails over a substantial part of its length.
A chassis according to either foregoing claim wherein the secondary longitudinal members (22, 24) are connected to the first cross member (14) at respective connection points which are lower than the front ends (10d, 12d) of the side rails.
A chassis according to any foregoing claim wherein each of the secondary longitudinal members (22, 24) has a front portion (22d, 24d) which is inclined upwards towards the front.
A chassis according to any foregoing claim further comprising a third cross member (26) extending in a transverse direction between the secondary longitudinal members (22, 24) at a position longitudinally spaced between the first and second cross members (14, 20).
A chassis according to any foregoing claim wherein the secondary longitudinal members (22, 24) are positioned below and inboard of the side rails (10, 12).
A chassis according to any foregoing claim wherein the central support sections (28, 30) each provide support for a suspension mount (28a, 30a).
A chassis according to any foregoing claim wherein the secondary longitudinal members (22, 24) are connected to the first cross member (14) at respective points inboard of the side rails (10, 12).
A chassis according to any foregoing claim wherein the side rails (10, 12), cross members (14, 20, 26) and secondary longitudinals (22, 24) are bonded together to form a single rigid structure.
A chassis according to any foregoing claim further comprising a recovery attachment (42) attached to the first cross member (14).
A vehicle chassis substantially as hereinbefore described with reference to the accompanying drawings.
A vehicle including a chassis according to any foregoing claim and a body mounted on the chassis.
