Abstract

In one embodiment, there is disclosed a blast mitigating differential housing for a vehicle, comprised of a first wall and a second wall in opposed spaced apart relation to each other. The first and second walls are separated by first and second side walls extending there between to define an inner space and an exterior surface. The side walls may be declined toward each other in a V shape. One of the first and second walls is equipped with an aperture to accommodate a vehicle drive line. The side walls are equipped with opposed apertures to accommodate the drive shafts and/or vehicle axles. The side walls may be further equipped with mounting structures along the exterior to accommodate a vehicle suspension system and/or steering elements. The inner space defined by the walls has a surface equipped for at least one vehicle differential mount.

First claim

What is claimed as new and desired to be protected by Letters Patent of the United States is:

1. A vehicle having a blast mitigating structure, comprising:
a housing mounted on an underside of the vehicle, the housing having side walls that are sloped downwardly and toward each other;
wherein the side walls that are sloped downwardly and toward each other form a cavity;
a differential contained at least partially within the cavity formed by the side walls that are sloped downwardly;
at least one drive shaft extending from the differential in a direction substantially perpendicular to the length of the housing, the at least one drive shaft extending through one of the side walls that are sloped downwardly and toward each other.

2. The vehicle of claim 1 , wherein said vehicle is a wheeled, tracked, amphibious, or air vehicle.

3. A vehicle having a blast mitigating structure, comprising:
a housing mounted on an underside of the vehicle and surrounding a differential, the housing having side walls that are sloped downwardly and toward each other, and the housing having a plurality of apertures to accommodate an input to the differential and outputs from the differential to wheels of the vehicle;
wherein the side walls converge to form a V-shape having an apex;
wherein the side walls that are sloped downwardly and toward each other form a cavity;
wherein the cavity is configured to contain a differential for the vehicle;
at least one opening formed within at least one of the side walls that are sloped downwardly, the opening configured to accommodate at least one drive shaft extending from the differential of the vehicle.

4. The vehicle of claim 3 , wherein said vehicle is a wheeled, tracked, amphibious, or air vehicle.

5. A vehicle having a blast mitigating structure, comprising:
a housing mounted on an underside of the vehicle and at least partially surrounding a differential, the housing having side walls that are sloped downwardly and toward each other, and which converge to form a V-shape having an apex;
wherein the side walls that are sloped downwardly and toward each other form a cavity;
wherein the cavity is configured to contain a differential for a vehicle;
at least one opening formed within at least one of the side walls that are sloped downwardly, the opening configured to accommodate at least one drive shaft extending from the differential.

6. The vehicle of claim 5 , wherein said vehicle is a wheeled, tracked, amphibious, or air vehicle.
