摘要： A frame assembly for a motor vehicle and method of manufacturing the same. The method includes the steps of: forming a rearward frame module, forming a forward frame module, and forming a central frame module including a pair of longitudinal central frame siderails. Each of the central frame siderails are constructed by 1) forming a sheet of metallic material into a longitudinal member having a generally U-shaped transverse cross section including a base portion and a pair of leg portions, 2) engaging opposite longitudinal ends of the longitudinal member and pulling the longitudinal ends in opposite directions with respect to the longitudinal extent of the longitudinal member in order to stretch the longitudinal member so that the metallic material forming the longitudinal member reaches its yield state; and 3) bending the longitudinal member having the U-shaped cross-section at two longitudinally spaced locations so that 1) at a first of the locations a) the base portion is bent generally within its plane, b) one of the leg portions is stretched, and c) an opposite one of the leg portions is compressed, and so that 2) at a second of the locations a) the base portion is bent generally within its plane, b) the one of the leg portions is compressed, and c) the opposite one of the leg portions is stretched. The forward frame module and the rearward frame module are then to opposite ends of the central frame module.

摘要： A rail frame assembly for a motor vehicle comprises a rearward frame module having a pair of generally parallel rearward frame rail members interconnected by a rearward cross-member assembly. A central frame module includes a pair of generally parallel central frame rail members interconnected by a central cross-member assembly, the central frame members each having a generally U-shaped transverse cross-sectional configuration including a vertical base wall portion and a pair of outwardly extending generally parallel horizontal wall portions extending from opposite ends of the base wall portion. The U-shaped central frame members are each bent between two spaced positions thereof, and one of the horizontal wall portions extending from one end of the base wall portion has metallic grains therein substantially stretched at a location between the spaced positions. In addition, an opposite one of the horizontal wall portions extending from an opposite end of the base wall portion has metallic grains therein substantially compressed at the location between the spaced positions. In addition, a forward frame module comprises a pair of generally parallel tubular forward frame rail members interconnected by a forward cross-member assembly. The tubular forward frame rail members each having a generally rectangular transverse cross-section of irregular shape and size.
