A door access device for a semi-trailer includes: a lock device to control access to the semi-trailer and a controller for the lock device. The lock device includes a door lock at a door of the semi-trailer, the lock device to be electrically actuated to lock and unlock the door. The controller programmed to: determine that a semi-tractor has established an electrical connection with the semi-trailer; determine whether the semi-tractor is authorized to connect to the semi-trailer; and, in response to a determination that the semi-trailer is authorized to connect to the semi-trailer, actuate the lock device to unlock the door.

A military vehicle includes a passenger capsule having a front end and a rear end, a front module coupled to the front end of the passenger capsule, a rear module coupled to the rear end of the passenger capsule, a generator, and an export power kit. The front module includes a front subframe, a prime mover, a front axle assembly, and a front differential coupled to the front axle assembly. The rear module includes a rear subframe, a rear axle assembly, and a transaxle coupled to the rear axle assembly, the prime mover, and the front differential. The generator is configured to be driven by the prime mover to generate electricity. The export power kit is coupled to the generator and configured to facilitate exporting power off of the military vehicle.

A pre-filling device for a braking system. The pre-filling device includes a pre-filling channel, a pre-filling pressure being inside the channel when the braking system is in a rest and hydro-boost position, and a mechanical valve configured to be opened following a transition from the rest and hydro-boost position to a working position of the braking system; and a hydraulic valve cooperating with the mechanical valve setting the pre-filling pressure inside the channel. The hydraulic valve includes in a first area, facing the mechanical valve, a hole communicating with the channel, and in a second area, hydraulically isolated from the first area, a preloaded resilient element in a chamber held at atmospheric pressure. The hydraulic valve is configured to be connected or not to be connected, by a reciprocating movement inside the channel, to a hydro-booster device and to keep a predetermined pre-filling pressure upon varying of the hydro-boost pressure.
