Abstract: An armored vehicle includes a body, a frame member extending longitudinally along a length of the body, and an armor assembly. The armor assembly includes an armor panel and a blast attenuator. The armor panel extends laterally outward from the frame member and is positioned at least partially underneath the body, and the blast attenuator is configured to deform during a blast event. The frame member is coupled to an inner portion of the armor panel with the blast attenuator.

Abstract: A structural blast tunnel for a vehicle includes a frame member, a first mounting interface, and a second mounting interface. The frame member includes an elongated curved portion having a first end, a second end, and a middle portion disposed between the first end and the second end. The frame member further includes a first sidewall and a second sidewall extending downwardly from the elongated curved portion. The frame member forms a structurally rigid section configured to direct blast energy outwards towards the first end and the second end.

Abstract: A vehicle includes a structural frame member including a structural tunnel, a first frame coupled to the structural tunnel and configured to engage a first axle assembly and a first suspension assembly, a second frame coupled to the structural tunnel and configured to engage a second axle assembly and a second suspension assembly, a cab assembly coupled to the structural tunnel, and an isolated joint positioned to support the cab assembly. The cab assembly is isolated from the structural tunnel, the first frame, and the second frame. The isolated joint includes a first bracket associated with the structural tunnel, a second bracket associated with the cab assembly, and a resilient member.

Abstract: A structural blast tunnel for a military vehicle includes a frame member that includes an elongated curved portion having a first end, a second end, and a middle portion disposed between the first end and the second end. The structural blast tunnel also includes a first mounting interface coupled to the first end and extending along the longitudinal axis of the frame member. The first mounting interface is configured to receive one of a front sub-frame and a standard frame of a vehicle. The structural blast tunnel finally includes a second mounting interface coupled to the second end and extending along the longitudinal axis of the frame member. The second mounting interface is configured to receive one of a rear sub-frame and a standard frame of a vehicle, and the frame member forms a structurally rigid section configured to direct blast energy outwards towards the first and second end. The structural blast tunnel may also include a secondary shield that increases the blast performance of this system.

Abstract: A blast resistant vehicle is disclosed that includes 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, and a cab assembly having a front portion and a rear portion and having a floor panel, a front firewall, a rear body panel, a first side panel, and a second side panel. The cab assembly is isolated from the structural frame member, the front sub-frame, and the rear sub-frame.

Abstract: An armor assembly is disclosed that includes a frame member, an underbody armor panel having an inner portion and an outer portion, and a first crushable member including a wall configured to deform during a blast event. The frame member is coupled to the underbody armor panel with the first crushable member.

Abstract: An axle assembly of a vehicle includes a side plate, a wheel end assembly, and a lower control arm. The side plate is part of a support structure of the vehicle, and the lower control arm extends between the side plate and the wheel end assembly. A spring member and a damper are each connected between the lower control arm and the side plate. The axle assembly further includes a shield fixed to the lower control arm, where the shield is designed to at least partially protect the vehicle from an explosive blast originating below the vehicle.

Abstract: An axle assembly for an undercarriage of a vehicle includes two side plates, a differential, and a skid plate. The two side plates have surfaces configured to support a vehicle hull. The differential is generally positioned between the two side plates. During operation of the axle assembly, the differential receives torque from a driveshaft and provides the torque to half shafts. The skid plate includes an array of beams extending between the side plates and below the differential. The skid plate is designed to shield the differential and portions of the undercarriage of the vehicle from ground obstacles.
