A front end bearing structure for the bodywork of a vehicle of the type including a pair of spaced apart left and right side front longitudinal bearer members, each having an upstanding, substantially perpendicular support member for supporting a suspension strut mount at a location above its respective front longitudinal bearer member. Each suspension strut mount is also supported at a front end portion thereof by an additional slanted supporting bearer member which is extended upwardly and rearwardly from a connection point on each front longitudinal bearer member at a point in front of the location of the juncture of the perpendicular support member and front longitudinal bearer member. In this way, each slanted supporting bearer member forms a closed triangular framework with its respective front longitudinal bearer member and perpendicular support member. The angle subtended by the slanted supporting bearer member and the longitudinal bearer member is preferably about 45.degree.. The resulting geometry provides for a stable and rigid connection and also promotes the favorable distribution of impact forces throughout the bearing structure in the event of a head-on collision. In an alternate embodiment, the perpendicular support member for the suspension mount is enclosed by a hollow section along its entire length to form a favorably rigid closed cross-sectional bearer member.
In a front-end bearing structure for a vehicle bodywork comprising a frame structure of bearers which includes a pair of spaced apart longitudinal bearer assemblies disposed along bottom sides of the bodywork, each of said bearer assemblies comprising a longitudinal bearer member, an upstanding, substantially perpendicular support member connected to an upper surface of said longitudinal bearer member for supporting a front suspension strut mount at a height above said longitudinal bearer member, a diagonally-oriented supporting bearer member having a first, lower end portion connected to said longitudinal bearer member and a second, upper end portion connected to said suspension strut mount, said diagonally-oriented supporting member is disposed forwardly of said perpendicular support member, said longitudinal bearer assemblies forming a closed triangular framework, as seen in elevation, the front-end bearing structure further including a pair of generally horizontally-oriented suspension strut bearer members for connecting each of said suspension strut mounts to a respective vertically-oriented and rearwardly disposed side door pillar at an upper region thereof and adjacent a connection point for a roof column member, wherein the improvement comprises in operative combination;
