The invention relates to a hydropneumatic valve for a vehicle train, comprising a hydraulic module, a pneumatic module and a mechatronic module, wherein the mechatronic module allows the pneumatic module to be activated independently of the hydraulic module.

Brake systems, vehicles having such brake systems, and methods of operating and installing the brake systems on vehicles. Such a brake system operates one or more brakes to reduce the speed of the vehicle through the operation of a brake pedal. The system includes a hydraulic circuit functionally coupled to the one or more brakes and configured to apply a braking force with the brake(s) that is in relation to a change in pressure of hydraulic fluid within the hydraulic circuit, and an air circuit functionally coupling the brake pedal to the hydraulic circuit. The air circuit is configured to convert manual actuation of the brake pedal to a change in the pressure of the hydraulic fluid within the hydraulic circuit and thereby apply a braking force in relation to a degree of actuation of the brake pedal.

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.

Electric equipment for a vehicle with an electropneumatic service brake device, in which at least one pneumatic brake control pressure is immediately and directly controlled to the electromagnetic backup valve, which is still being closed by a current, of at least one pressure regulating module in response to an assistance brake request signal regardless of a defect of an electric service brake circuit. For a failure of the electric service brake circuit, the electromagnetic backup valve, which is then in the currentless state, of the at least one pressure regulating module is automatically opened, and the brake pressure is immediately formed in the pressure regulating module based on the at least one pneumatic brake control pressure already present in the pressure regulating module. Thus, the reaction time of a pneumatic redundancy of the electropneumatic service brake device in response to electric defects is reduced.
