Vehicle Traction Battery Sub-Frame Assembly
First Claim
1. A vehicle underbody assembly comprising:
- a rear underbody structure;
a first sub-frame mounted to the rear underbody structure;
a vehicle component mounted to the first sub-frame;
a second sub-frame mounted to the rear underbody structure at a location adjacent the first sub-frame and including at least one reinforcement member extending toward the vehicle component, a first lateral member, a second lateral member, a pair of angle members extending between the first lateral member and the second lateral member, a trailer hitch mount extending rearward from the second lateral member, and a cross member extending between the pair of angle members; and
a traction battery mounted to the second sub-frame adjacent the vehicle component and below the rear underbody structure,wherein the at least one reinforcement member is oriented to contact the vehicle component or first sub-frame when a force moves the second sub-frame forward, and wherein the cross member is spaced from the first lateral member to support a portion of the traction battery.

Abstract
A vehicle underbody including a rear underbody structure, a rear differential, a sub-frame, and a traction battery is provided. The rear differential is mounted to the rear underbody structure. The sub-frame is mounted to the rear underbody structure rearward of the rear differential. The traction battery is mounted between the rear underbody structure and the sub-frame. A base portion of the traction battery defines a base portion plane that does not extend through the rear differential. The sub-frame may include at least two reinforcement members each having a ramp-shaped end extending toward the rear differential. The sub-frame may include a rear lateral member and a trailer hitch mount extending rearwardly therefrom. One of the reinforcement members and the trailer hitch mount may be aligned in parallel with a central longitudinal axis defined by the rear underbody structure.

11. A vehicle underbody assembly comprising:
-
a rear body structure; a first sub-frame mounted to the rear body structure; a rear differential mounted to the first sub-frame; a second sub-frame mounted to the rear body structure rearward of the first sub-frame and including a first lateral member, a second lateral member, a pair of angle members extending between the first lateral member and the second lateral member, a cross member extending between the pair of angle members, and a trailer hitch mount extending rearward from the second lateral member; and a traction battery mounted to the first lateral member between the rear body structure and the second sub-frame, wherein the first lateral member is arranged with the first sub-frame so the traction battery is mounted upon a plane extending horizontally along an axis vertically spaced above the first sub-frame. - View Dependent Claims (12, 13, 14, 15, 16)
