Vehicle frame with overlapped sections

摘要

A vehicle frame (200) has a rear portion with a rear siderail (204) of hat-shape cross-section, and a front portion with a front siderail (202) of C-shape cross-section received within the hat-shaped rear side-rail. The siderails are attached to each other at a joint (206) and have respective vertical sections (208) and (210) in overlapped contact with each other at the joint and providing a first mounting pad (230) of increased stock thickness. A cross member (226) is attached to the siderails at the joint and has a vertical flange (228) in overlapped contact with a respective vertical section (214) of the rear siderail to provide a second mounting pad (232) of increased stock thickness. A spring hanger (218) is mounted to and extends horizontally between the mounting pads.
