Isolated cab mounting system for an armored vehicle

1. A blast-resistant vehicle, comprising:

a structural frame member including a structural tunnel having a curved upper portion extending downward into a first side wall and a second side wall;

a first frame coupled to the structural frame member and configured to receive a first axle assembly and a first suspension assembly;

a second frame coupled to the structural frame member and configured to receive a second axle assembly and a second suspension assembly;

a cab assembly coupled to the structural frame member and having a front portion and a rear portion and including a floor panel, a front firewall, a rear body panel, a first side panel, and a second side panel, wherein the cab assembly is isolated from the structural frame member, the first frame, and the second frame; and

a front isolated joint configured to support the cab assembly, wherein the front isolated joint includes a frame bracket coupled to the structural frame member, a cab bracket coupled to the cab assembly, and a resilient member.

2. The blast resistant vehicle of claim 1 , wherein the front isolated joint couples the front portion of the cab assembly to a front portion of the structural frame member.

3. The blast resistant vehicle of claim 1 , wherein the resilient member is disposed between a mounting surface of the frame bracket and a corresponding mounting surface of the cab bracket.

4. The blast resistant vehicle of claim 1 , wherein the resilient member comprises a rubber isolation mount.

5. The blast resistant vehicle of claim 1 , wherein the frame bracket is coupled to at least one of the first and second side walls.

6. The blast resistant vehicle of claim 1 , further comprising an armor assembly including a wheel plate coupled to the structural frame member.

7. The blast resistant vehicle of claim 1 , further comprising a rear isolated joint configured to support the cab assembly.

8. The blast resistant vehicle of claim 7 , wherein the rear isolated joints couples the rear portion of the cab assembly to a rear portion of the structural frame member.

9. A blast-resistant vehicle, comprising:

a structural frame member;

a first frame coupled to the structural frame member and configured to receive a first axle assembly and a first suspension assembly;

a second frame coupled to the structural frame member and configured to receive a second axle assembly and a second suspension assembly;

a cab assembly coupled to the structural frame member and having a front portion and a rear portion and including a floor panel, a front firewall, a rear body panel, a first side panel, and a second side panel, wherein the cab assembly is isolated from the structural frame member, the first frame, and the second frame;

a front isolated joint configured to support the cab assembly; and

an armor assembly including a wheel plate coupled to the structural frame member, wherein the wheel plate defines an aperture proximate the front isolated joint configured to provide access to the front isolated joint.

10. A blast-resistant vehicle, comprising:

a structural frame member;

a first frame coupled to the structural frame member and configured to receive a first axle assembly and a first suspension assembly;

a second frame coupled to the structural frame member and configured to receive a second axle assembly and a second suspension assembly;

a cab assembly coupled to the structural frame member and having a front portion and a rear portion and including a floor panel, a front firewall, a rear body panel, a first side panel, and a second side panel, wherein the cab assembly is isolated from the structural frame member, the first frame, and the second frame; and

an armor assembly, wherein the armor assembly includes a plurality of panels having overlapping edges to protect the cab assembly from debris.

11. An military vehicle, comprising:

a blast resistant assembly including:

a front sub-frame assembly including a front suspension and a front axle,

a rear sub-frame assembly including a rear suspension and a rear axle,

a structural frame member coupled to the front sub-frame and the rear sub-frame,

an armor assembly coupled to the frame member, and

a prime mover coupled to at least one of the front sub-frame and the rear sub-frame; and

an isolated cab assembly having an outer surface, wherein spacing between the outer surface of the isolated cab assembly and the blast absorbing assembly defines a blast gap,

wherein the armor assembly comprises a plurality of panels having overlapping edges to protect the isolated cab assembly from debris, the plurality of panels including an under body panel extending from the structural frame member, a side armor panel coupled to the under body panel, and a door armor plate coupled to a side of the cab assembly.

12. The military vehicle of claim 11 , wherein the blast gap surrounds the isolated cab assembly.

13. The military vehicle of claim 11 , wherein the blast gap is at least 0.25 inches.

14. The military vehicle of claim 11 , wherein the side armor panel extends upward past a bottom edge of the door armor plate to provide ballistic overlap protection.
