Abstract
A ladder type of vehicular body and frame assembly includes a pair of side rails, each of which is formed from three separate members, namely, a front closed channel structural member, a center open channel structural member, and a rear closed channel structural member. The closed channel structural members may be formed having a generally rectangular cross sectional shape, while the open channel structural members may be formed having a generally C-shaped cross sectional shape. The rear ends of the front closed channel structural members are connected to the front ends of the center open channel structural members at respective joints, such as by welding, riveting, bolting, adhesives, magnetic pulse welding, and the like. Similarly, the rear ends of the center open channel structural members are connected to the front ends of the rear closed channel structural members at respective joints, such as by welding, riveting, bolting, adhesives, magnetic pulse welding, and the like. The closed channel structural members are preferably formed to the desired shape by hydroforming. The open channel structural members may be formed to the desired shape by any conventional metal forming process, such as by pressing or roll forming.
