Abstract: A chassis frame structure consisting of the merger of two chassis frames with different widths, which include a module to facilitate the difference in size as well as integrate an electric motor drive solution for the purpose of battery electric commercial vehicles. The module mounting structure includes a plurality of brackets allowing for form-fit assembly of an existing vehicle chassis frame with a new pre-assembled chassis frame.

Abstract: A mounting structure for a series of electric battery packs (21); such packs get mounted between the two lateral chassis rails (11, 12) of a medium or heavy-duty electric vehicle. The battery packs get inserted through either the forward-facing or rear-facing ends of the chassis frame. Such chassis frame is created by joining a set of double up frame rails (11, 12) together with U-shaped cross members (32), allowing access to the interior of the chassis frame, and allowing a simplified removal and replacement of batteries for maintenance purposes.

Abstract: A u-shaped crossmember is employed in the construction of a chassis frame of a medium or heavy duty battery electric vehicle. In the design, frame rails are joined by at least one of U-shaped cross members, which comprises a main center section and four or more support arms, which extend away from the main center section of the cross member in the transverse direction of the longitudinal frames. The cross members, in one example, include two brackets. Each bracket has two arms connected by a center main portion. These brackets can be fabricated by creating a plurality of angles in several locations that add up to 90-degrees. The angled design allows the transmission of longitudinal and lateral forces to both frame rails. Due to U-shaped nature of the cross member, the body of the chassis frame is opened to allow for installation of components, subassemblies, and especially battery packs, etc.
