Abstract

A method for manufacturing a vehicle frame is disclosed. An upper body of the vehicle frame is formed, the upper body configured to be joined with an underbody of the vehicle frame at a first component of the upper body. The underbody of the vehicle frame is formed, the underbody configured to be joined with the upper body at a first component of the underbody. After forming the upper body and the underbody, a point on the upper body is aligned with a desired position for the point, independent of an alignment between the first component of the upper body and the first component of the underbody. After aligning the point on the upper body with the desired position for the point, the first component of the upper body is joined to the first component of the underbody.

First claim

1 . A method for manufacturing a vehicle frame, the method comprising:
forming an upper body of the vehicle frame, the upper body configured to be joined with an underbody of the vehicle frame at a first component of the upper body; forming the underbody of the vehicle frame, the underbody configured to be joined with the upper body at a first component of the underbody; after forming the upper body and the underbody, aligning a point on the upper body with a desired position for the point, independent of an alignment between the first component of the upper body and the first component of the underbody; and after aligning the point on the upper body with the desired position for the point, joining the first component of the upper body to the first component of the underbody.

2 . The method of claim 1 , wherein after aligning the point on the upper body with the desired position for the point, the first component of the upper body is misaligned with the first component of the underbody, and the first component of the upper body and the first component of the underbody are joined while the first component of the upper body and the first component of the underbody are misaligned.

3 . The method of claim 1 , wherein the point on the upper body is on a second component of the upper body, different from the first component of the upper body.

4 . The method of claim 3 , wherein the second component of the upper body comprises one or more of an A-pillar, a B-pillar and a C-pillar.

5 . The method of claim 3 , wherein the second component of the upper body comprises a vehicle wheel well.

6 . The method of claim 1 , wherein the desired position for the point on the upper body is with respect to a component of the underbody, other than the first component of the underbody.

7 . The method of claim 6 , wherein the component of the underbody is a suspension component.

8 . The method of claim 1 , wherein the first component of the upper body comprises a side sill of the upper body.

9 . The method of claim 1 , wherein the first component of the underbody comprises a frame rail of the underbody.

10 . The method of claim 1 , wherein joining the first component of the upper body to the first component of the underbody comprises joining the first component of the upper body to the first component of the underbody using one or more mounting brackets.

11 . The method of claim 10 , wherein joining the first component of the upper body to the first component of the underbody comprises:
after aligning the point on the upper body with the desired position for the point, determining one or more locations for the one or more mounting brackets on the first component of the upper body; affixing the one or more mounting brackets to the one or more locations on the first component of the upper body; and joining the one or more mounting brackets to the first component of the underbody.

12 . The method of claim 11 , wherein joining the one or more mounting brackets to the first component of the underbody comprises joining the one or more mounting brackets to one or more mounting joints on the first component of the underbody, wherein the one or more mounting joints are fixedly formed on the first component of the underbody before the point on the upper body is aligned with the desired position for the point.

13 . The method of claim 11 , wherein the one or more mounting brackets comprise a first mounting bracket and a second mounting bracket, and the first mounting bracket and the second mounting bracket are affixed to different relative vertical locations on the first component of the upper body.

14 . The method of claim 1 , further comprising:
after forming the upper body and the underbody, aligning a second point on the upper body with a desired position for the second point, independent of the alignment between the first component of the upper body and the first component of the underbody, wherein joining the first component of the upper body to the first component of the underbody is after aligning the point on the upper body with the desired position for the point and aligning the second point on the upper body with the desired position for the second point.

15 . A vehicle frame comprising:
an upper body joined with an underbody of the vehicle frame at a first component of the upper body; and the underbody joined with the upper body at a first component of the underbody, wherein the first component of the upper body is joined to the first component of the underbody independent of an alignment between the first component of the upper body and the first component of the underbody.
