Abstract

A front upper frame connection for a space frame can comprise a top surface; a bottom surface opposite the top surface; a right-side surface; a left-side surface opposite the right-side surface; a front surface; a rear surface opposite the front surface; a pair of forward support plates provided on the front surface; a pair of forward flat mounting surfaces; and a pair of rocker attachment interfaces located on the top surface adjacent to the rear surface and respectively the right-side surface and the left-side surface. The front surface and the forward support plates can define a cutout section. Each of the forward support plates is curved and runs outward from a transverse centerline of the top surface and then forward.

First claim

The invention claimed is:

1. A front upper body support and frame connection fabrication for a space frame of a rear haul truck, the front upper body support and frame connection fabrication comprising:
a top surface;
a bottom surface opposite the top surface;
a right-side surface;
a left-side surface opposite the right-side surface;
a pair of forward support plates configured to support a pair of front upper suspension connection fabrications;
a pair of forward flat mounting surfaces configured to respectively fixedly attach to the front upper suspension connection fabrications;
a cutout section positioned between and integral to the pair of forward support plates;
a rear left-side mounting surface located at a rear of the left-side surface and configured to weldably attach a cab support frame tube;
a rear right-side mounting surface located at a rear of the right-side surface and configured to weldably attach a horizontal frame support fabrication;
a pair of outer bottom mounting surfaces located at a rear of the bottom surface and orientated toward the left-side surface and right-side surface, respectively, and configured to weldably attach a pair of front upper frame connection castings;
a pair of inner bottom mounting surfaces located at the rear of the bottom surface and orientated away from the left-side surface and right-side surface, respectively, and configured to weldably attach a pair of angled front frame tubes;
a pair of rocker attachment interfaces located at a rear of the top surface and positioned toward the left-side surface and right-side surface, respectively, and configured to pivotably attach a pair of support rockers; and
a truck cab mounting point located on the top surface and configured to receive a cab isolation mount.

2. The front upper body support and frame connection fabrication of claim 1 , wherein the top surface has a length greater than at least twice a width thereof.

3. The front upper body support and frame connection fabrication of claim 1 , wherein the rocker attachment interfaces are fabrications.

4. The front upper body support and frame connection fabrication of claim 1 , wherein the truck cab mounting point is between the forward flat mounting surface and the rocker attachment interface on a left side of the top surface.

5. The front upper body support and frame connection fabrication of claim 1 , wherein the forward support plates extend above the top surface.

6. The front upper body support and frame connection fabrication of claim 1 , wherein the forward support plates extend forward past the forward flat mounting surfaces.

7. A space frame of a rear haul truck comprising:
a front upper body support and frame connection fabrication having a top surface, a bottom surface opposite the top surface, a right-side surface, and a left-side surface opposite the right-side surface;
a pair of support rockers attached to the top surface of the front upper body support and frame connection fabrication via respective rocker attachment interfaces on the top surface of the front upper body support and frame connection fabrication;
a pair of front upper frame connections attached to the bottom surface of the front upper body support and frame connection fabrication via respective outer bottom mounting surfaces on the bottom surface of the front upper body support and frame connection fabrication; and
a pair of angled front frame tubes attached to the bottom surface of the front upper body support and frame connection fabrication via respective inner bottom mounting surfaces on the bottom surface of the front upper body support and frame connection fabrication,
wherein the front upper body support and frame connection fabrication further includes:
a pair of forward support plates,
a pair of forward flat mounting surfaces, and
a cutout section between the forward support plates.

8. The space frame of claim 7 , wherein the forward support plates are forward of the forward flat mounting surfaces in a length direction of the space frame, the forward flat mounting surfaces are forward of the rocker attachment interfaces in the length direction of the space frame, and the rocker attachment interfaces are forward of a rear surface of the front upper body support and frame connection fabrication.

9. The space frame of claim 7 , wherein the front upper body support and frame connection fabrication further includes:
a rear left-side mounting surface located at a rear portion of the left-side surface; and
a rear right-side mounting surface located at a rear portion of the right-side surface.

10. The space frame of claim 9 , further comprising:
a cab support frame tube weldably attached to the rear left-side mounting surface; and
a horizontal frame support fabrication weldably attached to the rear right-side mounting surface.

11. The space frame of claim 7 , wherein the forward support plates each have a first portion that is perpendicular to a rear surface of the front upper body support and frame connection fabrication and a second portion that is parallel to the right-side surface and left side surfaces.

12. The space frame of claim 7 , wherein a length of the front upper body support and frame connection fabrication is greater than a width of the front upper body support and frame connection fabrication, the length running in a width direction of the space frame.

13. The space frame of claim 7 , wherein the rocker attachment interfaces are positioned at respective opposite rear corners of the top surface of the front upper body support and frame connection fabrication.

14. A front upper frame connection for a space frame comprising:
a top surface;
a bottom surface opposite the top surface;
a right-side surface;
a left-side surface opposite the right-side surface and parallel to the right-side surface;
a front surface;
a rear surface opposite the front surface;
a pair of forward support plates provided on the front surface;
a pair of forward flat mounting surfaces; and
a pair of rocker attachment interfaces located on the top surface adjacent to the rear surface and respectively the right-side surface and the left-side surface,
wherein the front surface and the forward support plates define a cutout section, and
wherein each of the forward support plates is curved such that a first portion is parallel to the rear surface and a second portion is perpendicular to the rear surface, the first portion being closer to a transverse centerline of the front upper frame connection than the second portion.

15. The front upper frame connection of claim 14 , further comprising:
a rear left-side mounting surface located at a rear of the left-side surface;
a rear right-side mounting surface located at a rear of the right-side surface;
a pair of outer bottom mounting surfaces located at a rear of the bottom surface and orientated toward the left-side surface and right-side surface, respectively; and
