Abstract
One variation may include using a plurality of node structures to assemble a uniframe.
Claims16
A method comprising:
- assembling a vehicle uniframe comprising:
- providing a right rail assembly and a left rail assembly comprising:
- providing a right side front node structure and a left side front node structure and a right side rear node structure and a left side rear node structure having at least one chassis component attachment point and at least one fixture mounting point;
- attaching the left side and the right side front node structures and the left side and the right side rear node structures to an assembly fixture;
- top loading a first end of a right center rail segment onto the right side front node structure and a second end of the right center rail segment onto the right side rear node structure;
- top loading a first end of a left center rail segment onto the left side front node structure and a second end of the left center rail segment onto the left side rear node structure;
- axially inserting a right front rail segment into the right side front node structure;
- axially inserting a left front rail segment into the left front side node structure;
- axially inserting a right rear rail segment into the right side rear node structure;
- and axially inserting a left rear rail segment into the left side rear node structure.
