A vehicle has a novel frame structure that comprises two novel frame rails that extend parallel to the longitudinal axis of the vehicle and cross-members that are fixedly engaged between the two novel frame rails. Each of the novel frame rails comprises a web that extends vertically along the length of the frame rail, an upper flange that extends horizontally from an upper end of the web, and a lower flange that extends horizontally from a lower end of the web. Each of the novel frame rails further comprises one or more reinforcing lips, each of which extends vertically from an outer end of either the upper flange or the lower flange.

Vehicle with novel frame rails

The invention relates to a motor vehicle frame. The frame is constructed from two parallel siderails running longitudinally down the length of the vehicle. An intermediate cross member support is positioned between the siderails to support a driver's cab. A datum support hole is positioned through each siderail to support mounting of one end of the cross member support for the driver's cab. The remaining support holes are arrayed in rows and columns positioned with reference to the datum support hole. A first row of supplemental support holes runs parallel to a bottom flange on each siderail and includes the datum support hole. A second row of supplemental support holes in each siderail runs parallel to and above the first row. A third row of supplemental support holes in each siderail runs parallel to the first and second rows and is positioned above the second row by the distance as the second row is above the first row.
