US12728824 - Military vehicle

A passenger capsule includes a frame rail-less monocoque hull structure having a front end and a rear end. The first protrusion and the second protrusion provide a pair of rear lift points. The frame rail-less monocoque hull structure includes a roof, a floor, and sidewalls that are bolted together. The floor defines a tunnel having an arcuate-shaped profile extending into an interior of the frame rail-less monocoque hull structure. The front end of the frame rail-less monocoque hull structure includes a plurality of front module interfaces. The plurality of front module interfaces are configured to releasably couple with a front module including a front subframe assembly and a front axle. The rear end of the frame rail-less monocoque hull structure includes a plurality of rear module interfaces. The plurality of rear module interfaces are configured to releasably couple with a rear module including a rear subframe assembly and a rear axle.
