A military vehicle includes a passenger capsule including a roof, a floor, and sidewalls that define an interior, a driver seat and a passenger seat disposed within the interior of the passenger capsule, and a belly deflector coupled to an exterior of the passenger capsule and positioned beneath the floor. 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.

Land vehicle provided with a frame; four wheels; and four compensation systems each associated with a respective wheel. The vehicle is also provided with a control unit, in particular a hydraulic control unit, which has compensation systems and connects each wheel to the other wheels. The vehicle has a plurality of hydraulic filters, which are each arranged between a wheel and the respective compensation system; the hydraulic filters are low-pass filters designed to reduce (in particular stop), in case of undesired frequencies, the flow of a transmission fluid and, hence, the association between the wheel and the respective compensation system.

An embodiment composite material spring for a suspension device of a vehicle includes a leaf spring configured to be installed in a body of the vehicle and a wheel of the vehicle, a first fluid container installed at a left side of a center of the leaf spring and including a first magnetorheological fluid, and a second fluid container installed at a right side of the center of the leaf spring and including a second magnetorheological fluid.

A vehicle height adjustment system includes: a cylinder housing part having an inner space configured to receive working fluid; a piston part positioned in the cylinder housing part, the piston part configured to move linearly in response to the working fluid transferred to the cylinder housing; a damper rod part positioned in the piston part; a protrusion part protruding outward from the damper rod part; and a guide part formed in the piston part facing the protrusion part, wherein the protrusion part is inserted into the guide part.

A dirt protection cover arrangement with a semi-trailer (2) and a towing vehicle (3), for closing a hollow-bored king pin (21) on the semi-trailer (2) for an automatic fifth-wheel coupling, the king pin (21) being arranged on the underside (20) of the semi-trailer (2) as a counter-bearing for a fifth wheel (31) of the towing vehicle (3), a dirt protection cover device (1) being arranged such that it is adjacent to the underside (20) of the semi-trailer (2) and can rotate about the king pin (21), said dirt protection cover device including a dirt protection cover (11) for covering the borehole (22) in the king pin (21), and the dirt protection cover (11) being configured on the dirt protection cover device (1) such that, during the coupling process, it can be displaced from a base position covering the borehole (22) in the king pin (21) into a coupled position exposing the borehole. Also, a dirt protection cover device (1) for a dirt protection cover arrangement, and a coupling method involving same.
