A military vehicle includes a passenger capsule. The passenger capsule includes a sidewall defining a front door aperture and a rear door aperture, a front door positioned over the front door aperture, a rear door positioned over the rear door aperture, and a latching mechanism configured to secure the front door and the rear door in a closed positioned. The sidewall includes an interlocking door frame portion positioned (i) along an exterior of the sidewall between the front door aperture and the rear door aperture and (ii) proximate the latching mechanism such that the front door and the rear door engage with the interlocking door frame portion positioned along the exterior of the sidewall between the front door aperture and the rear door aperture when the front door and the rear door are closed and engaged with the latching mechanism.

A military vehicle 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 passenger capsule has a frame rail-less monocoque hull structure. The front module includes a front axle, a front differential coupled to the front axle, and a prime mover. The rear module includes a rear axle and a transaxle coupled to the prime mover, the rear axle, and the front differential.

A vehicle braking system includes an assistance device, having a vacuum pump driven by an engine for communicating vacuum to a chamber of the assistance device. A control valve is interposed along a fluid line between the pump and the chamber. The control valve is in its first operative condition, where the inlet side of the vacuum pump communicates with the chamber, when the pressure within the chamber is above a predetermined value; and is in its second operative condition, where the inlet side of the vacuum pump communicates with the atmosphere, when pressure within the chamber is below a predetermined value. In this second condition the pump intakes air from and feeds air into the atmosphere, thereby reducing the energy consumption by the engine required for driving the pump during stages where, within the chamber there is a vacuum sufficient for the regular operation of the braking system.

A method monitoring a pneumatically actuatable brake for motor vehicles, wherein an air gap of the brake is ascertained using measured position values provided by a brake wear sensor, includes ascertaining a reference position value of the brake wear sensor during unbraked travel, determining multiple value pairs of discrete position values and a current brake pressure P at a same point in time during a braking procedure, ascertaining a characteristic function interpolating the value pairs, determining a characteristic position value according to the characteristic function for a selected brake pressure, and determining an actual value of the air gap by subtracting the reference position value from the characteristic position value.

A redundant brake control system for a locomotive consist that employs corresponding air brake control units in each locomotive that are interconnected by an inter-unit cable extending between the locomotives. Power to the air brake control units may be selectively connected and disconnected to select which air brake control unit is controlling the brakes of the train. The electronic brake valves associated with the air brake control units remain powered so that braking command may be send from either electronic brake valve and responded to by whichever of the air brake control valves have been provided with power. The control of power may be performed by the locomotive control system so that an operator can easily switch control between the air brake control units from the cab of any locomotive in the consist.
