Abrégé anglais

Vehicle provided with revolving turret comprising an
armor-plated cockpit (2), a system for the motion of the central
revolving turret (4) upon which a main armament (5) can be
mounted. This turret is connected to the armor-plated cockpit of
the vehicle by means of a circumferential fifth-wheel (8) which
allows the revolving of the turret around a substantially vertical
axis which passes through the center of this fifth-wheel. The
basis (9) of this turret presents a hatch (10) for the
communication between the interior of the turret and the interior
of the cockpit (2) of the vehicle.

TITLE: "Vehicle provided with revolving turret".
The present invention relates to a vehicle, for instance a
tracked vehicle or a rotated vehicle of military type, provided
with revolving turret with artillery means.
To the state of the art are known armored vehicles movable by
means of a system of tracks and provided with a central revolving
turret upon which it is mounted the main armament of the truck
which is usually constituted by a cannon. This cannon is provided
with thermal sensors and usually has a system for the gas recovery
and fire damping and is also hydraulically and/or electrically
stabilized.
The turret is also usually provided with one or more machine
guns and with various pointing and vision means or systems, such
as a stabilized niyht/day periscopic viewer for the commander, a
stabilized viewer with thermal view and laser telemeter for the
gunner, apart from a fire controlling computer. This last one
receives data from the various sensors of the vehicle and is able
to process all the data for determining the best firing
conditions.
Normally, in these types of vehicles, classified as tanks, or
combat vehicles or troops transport vehicles, the interior where
there is the position of the pilot and the interior of the turret

ar e separated between them, for safety reasons united with
strength reasons of the turret in general.
The Applicant has realized a vehicle provided with revolving
turret with armament which communicates with the interior of the
vehicle through an emergency hatch, preferably armor-plated, which
opens at the bottom or the basis of the turret toward the interior
of the armor-plated vehicle.
An aspect of the present invention relates to a vehicle
provided with a central revolving overhead turret, said vehicle
comprising: an armor-plated cockpit comprising an interior space;
an overhead turret, the turret having substantially no cockpit
penetration, the turret being configured for mounting a main
armament; a system for moving the central revolving overhead
turret, the system for moving the central revolving overhead
turret comprising a circumferential bearing, said overhead turret
comprising a base and being connected to the armor-plated cockpit
by said circumferential bearing to allow revolving of the overhead
turret around a substantially vertical axis passing through a
center of said bearing, said base comprising a floor located
completely external to the cockpit and a hatch attached to the
floor by a pair of opposed hinges, wherein the hatch pivots about
the hinges toward the interior space of the cockpit from a first
position closing a passage in the floor to a second position
providing communication between the overhead turret and the

turret according to the present invention;'
= Figure 3b shows a front schematic view of the turret
according to the present invention;
= Figure 3c shows a magnified particular of the turret in
its lower part according to the present invention.
With reference to the above mentioned figures the vehicle
according to the present invention comprises an armor-plated
cockpit 2 and preferably a track motion system 3 or alternatively
rotated and is provided with a central revolving turret 4 upon
which is mounted main armament 5 which is usually constituted by a
cannon or by another weapon or actuator.
This cannon can be provided with thermal sensors and usually
has a system for the gas recovery and fire damping and is also
hydraulically stabilized.
The turret is also usually provided with one or more machine
guns 6 and with various pointing and vision means or systems, such
as a stabilized night/day periscopic viewer 7 for the commander, a
stabilized viewer with thermal view and laser telemeter for the
gunner, apart from a fire controlling computer. The latter
receives data from the various sensors of the vehicle and is able
to process all the data for determining the best firing
conditions.

The turret is connected to the armor-plated cockpit of the
vehicle by means of a circumferential fifth-wheel 8 which allows
the complete revolving (by 360 ) of the turret with respect to a
vertical axis passing through the centre of this fifth-wheel.
According to the present invention, basis 9 of this turret
presents a hatch 10 for the communication between the interior of
the turret where there are the controls for the main and auxiliary
armaments, and the interior of cockpit 2 of the vehicle.
This hatch permits the access to the turret not only from
outside and from the top of the vehicle, as traditionally happens,
but also by the personnel who is inside the cockpit itself of the
vehicle, for the purpose of, for instance, looking over through
episcopes, refilling the ammunition chest, carrying out emergency
shots, having another escape way from the cockpit of the vehicle
itself and carrying cut maintenance operations.
Preferably, this hatch opens at the bottom or basis of the
turret toward the interior of the cockpit of the vehicle by means
of a couple of opposed hinges 11.
Preferably, this hatch has a quadrangular or rectangular
shape.
The hatch is also provided with closure means 12 and grasping
means 13 which are accessible from the interior of the cockpit of
the vehicle.

The turret according to a peculiar characteristic of the
present invention does not have parts which enter the hull or the
cockpit of the vehicle. The only communication or connection
element is hatch 10.
