A military vehicle includes a passenger capsule, a driver seat, a passenger seat, and a belly deflector. The passenger capsule includes a roof, a floor, and sidewalls that define an interior. The sidewalls include mounting interfaces positioned along bottom edges thereof and extending directly therefrom past the floor. The driver seat and the passenger seat are disposed within the interior of the passenger capsule. The belly deflector is positioned beneath the floor. The belly deflector has lateral ends that are coupled to the mounting interfaces such that the lateral ends of the belly deflector are engaged with the passenger capsule. The belly deflector is spaced from the floor such that the floor is configured as a floating floor. The floor and the belly deflector provide two levels of underbody protection.

A military vehicle includes a chassis, an axle, a suspension system, and a driveline. The chassis includes a passenger capsule, a front module coupled to a front end of the passenger capsule, and a rear module coupled to a rear end of the passenger capsule. The axle is supported by the rear module. The suspension system is positioned between the rear module and the axle. The suspension system includes a first gas spring, a second gas spring, a first damper, and a second damper. The first damper and the second damper are cross-plumbed to provide a fluid body roll control function. The driveline is configured to drive the axle. The driveline includes a component having a housing that functions as a structural component of the rear module. The first gas spring, the second gas spring, the first damper, and the second damper are directly coupled to the housing.

A vehicle includes a passenger capsule having a first end and a second end, a front module coupled to the first end of the passenger capsule and including a front axle assembly, an engine coupled to the front module, a rear module coupled to the second end of the passenger capsule and including a rear axle assembly, and a transaxle coupled to the rear module and the engine. The transaxle includes a transfercase component and a differential component contained at least partially within a housing that defines a structural component of the rear module. The rear axle assembly includes at least one of an upper control arm, a lower control arm, a spring, and a damper that is directly coupled to the transaxle.

A vehicle includes a passenger capsule, a front module, an engine coupled to the front module, a rear module, a transaxle, and a plurality of interfaces. The passenger capsule includes a structural shell having a first end and a second end, and the front module is coupled to the first end of the passenger capsule and has a first longitudinal frame member, a second longitudinal frame member, and a front axle assembly. The rear module is coupled to the second end of the passenger capsule and includes a rear axle assembly. The transaxle is coupled to the rear module and the engine, and the transaxle includes a housing that defines a structural component of the rear module.

A military vehicle includes a passenger capsule, a front module, a rear module, and a control system. The front module includes a front frame assembly coupled to a front end of the passenger capsule, a front axle, and a front suspension positioned between the front axle and the front frame assembly. The rear module includes a rear frame assembly coupled to a rear end of the passenger capsule, a rear axle, and a rear suspension positioned between the rear axle and the rear frame assembly. Each of the front suspension and the rear suspension includes a pair of gas springs and a pair of dampers. The control system is configured to monitor a ride height of the military vehicle and control the pair of gas springs of the front suspension and the rear suspension to adjust the ride height as load is added to or removed from the military vehicle.

A military vehicle includes a passenger cabin, a front axle, a rear axle, an engine positioned forward of the passenger cabin, a front lift assembly positioned forward of the passenger cabin and providing a pair of front lift points, a rear lift assembly positioned rearward of the passenger cabin and providing a pair of rear lift points, a generator configured to be driven by the engine to generate electricity, and an export power kit configured to facilitate exporting power off of the military vehicle.

A military vehicle assembly includes a rear module. The rear module includes a rear frame assembly, a bed supported by the rear frame assembly, a rear tractive assembly, a transaxle supported by the rear frame assembly and coupled to the rear tractive assembly, and a rear suspension system including at least one component extending between a housing of the transaxle and the rear tractive assembly. The rear frame assembly has one or more upper interfaces and one or more lower interfaces. The one or more upper interfaces are configured to detachably couple to a rear end of a passenger capsule of a military vehicle. The one or more lower interfaces are configured to detachably coupled to a bottom of the passenger capsule. The transaxle is configured to couple to a prime mover and a front differential of the military vehicle.

A method includes providing a plurality of passenger capsules where each of the plurality of passenger capsules has a frame rail-less monocoque hull structure and the plurality of passenger capsules include (a) a first passenger capsule defining four door openings and (b) a second passenger capsule defining two door openings; providing a plurality of front modules; providing a plurality of rear modules; coupling (a) a first front module to a front end of the first passenger capsule and (b) a first rear module to a rear end of the first passenger capsule to provide a first military vehicle variant; and coupling (a) a second front module to a front end of the second passenger capsule and (b) a second rear module to a rear end of the second passenger capsule to provide a second military vehicle variant.

A brake system includes an air-to-hydraulic intensifier configured to couple to a brake actuator that engages a brake to limit movement of a tractive element where the air-to-hydraulic intensifier is configured to receive a supply of air and provide a hydraulic fluid to the brake actuator based on the supply of air to overcome a brake biasing force of the brake actuator to disengage the brake actuator from the brake to permit movement of the tractive element, a hydraulic reservoir coupled to the air-to-hydraulic intensifier, and a valve. The valve includes a first port fluidly coupled to the air-to-hydraulic intensifier, a second port fluidly coupled to the hydraulic reservoir, a third port fluidly coupled to the brake actuator, and a valve gate that is repositionable between a first position that couples the first port to the third port and a second position that couples the second port to the third port.
