Problems solved by technology

Thus, a side sill that works on one car may not work on another car of a different length or size
Also, automotive frames are often formed entirely from stampings, resulting in high manufacturing costs, especially when trying to increase frame integrity

Embodiment Construction

[0022] FIG. 1 is an illustration of an embodiment of a modular underbody frame 10 for a motor vehicle in accordance with the principles of the present invention. FIG. 2 shows a partially exploded view of the vehicle frame 10 . The frame 10 includes a pair of laterally spaced, longitudinally extending central side member structures 12 , a pair of front side member structures forming a front assembly 76 , and a pair of rear side member structures forming a rear mold assembly 78 .

[0023] The use of the mold assemblies 76, 78 with the center side member structure 12 has great versatility in forming the vehicle frame 10 or in forming other vehicle frames. For example, in the production of other vehicle frames, the mold assemblies 76 and 78 may be used together or separately with other center side member structures. Thus, significant savings can be achieved by applying the mold assemblies 76 and 78 to other motor vehicle frames. Alternatively, the mold assemblies 76 and 78 can b...

Abstract

A module for a frame for a motor vehicle with a pair of laterally spaced, longitudinally extending central side rail structures. The module including a pair of tubular hydroformed side rail members and a laterally extending connecting structure connected between the pair of side rail members to secure the pair of side rail members in laterally spaced, fixed relation to one another. Each first portion of the pair of side rail members extending longitudinally and each second portion of the pair of side rail members extending laterally relative to the respective first portion and each second portion having an end being constructed and arranged to form a joint with a portion of a respective central side rail structure such that the end of each of the pair of side rail members extends generally laterally through a side of the respective central side rail structure.

Description

technical field [0001] This invention relates to structural vehicle frames. In particular, the illustrated embodiments of the invention relate to a frame for a motor vehicle. Background technique [0002] A frame for an automobile generally consists of a pair of side members extending the entire length of the automobile. Thus, cars of different lengths have frames of different lengths. Thus, a side sill that works on one car may not work on another car of a different length or size. Also, automotive frames are often formed entirely from stampings, resulting in high manufacturing costs, especially when trying to increase the integrity of the frame. [0003] These and other problems are addressed by illustrative embodiments of the present invention. Contents of the invention [0004] The present invention provides a frame for a motor vehicle comprising: a pair of transversely spaced, longitudinally extending central side sill structures, each of said central side sill st...
