3,401,598 GUN MOUNTING FOR ARMED VEHICLES Charles C. Sons, Jr., Peoria, Ill., assignor to Caterpillar Tractor Co., Peoria, 111., a corporation of California Filed Sept. 6, 1966, Ser. No. 577,522 2 Claims. (Cl. 89-40) ABSTRACT OF THE DISCLOSURE Support mechanism for a gun and turret of a military vehicle provides for traverse and elevation of the gun and in addition provides for raising and lowering of the gun and turret to increase effectiveness during firing and to reduce the vehicle height at other times.
This invention relates to combat vehicles and more particularly to maneuverable support mechanism for mounting a gun thereon.
It is usually preferable that Vehicles designed for combat operations, such as military tanks, armored personnel carriers, and the like, be of the'minimum height consistent with functional requirements. A low profile vehicle is less conspicuous and presents a much more difiicult target to an enemy. In addition, a low vehicle is more stable on uneven terrain, encounters fewer problems with overhead clearances, and can usually be designed with more sharply sloping surfaces which may deflect enemy fire.
Such vehicles frequently carry one or more heavy guns which are fastened to the body of the vehicle by some form of support mechanism which allows the gun to be pivoted both horizontally and vertically for aiming purposes. Many vehicles of this class are armored and have a turret structure which encloses the breech casing of the gun. The turret usually turns with the gun and therefore is also carried in part by the gun support mechanism. In most instances it is the gun and its mounting structure which determine the overall height of the vehicle. Accordingly there has heretofore been a tendency to situate the gun as low as is practical in order to achieve the desired 7 low vehicle profile.
There are however, some definite advantages to situating the gun high on the vehicle. A wide gun traverse angle, which should preferably be a full 360, can easily be provided for as interference between the gun barrel and other elements of the vehicle is more readily avoided. There is also a tactical advantage in that the gun may be more effectively used in combat when fired from a relatively high point.
In the design of combat vehicles some compromise has usually been made with the result that vehicle height has not heretofore been completely minimized.
The present invention provides for reconciling the opposing considerations so that an extremely low profile vehicle becomes practical without sacrificing the battlefield effectiveness of the gun. In particular the invention is a gun support mechanism which provides for selectively raising and lowering the gun and associated turret structure relative to the vehicle according to changing operational requirements.
Accordingly it is an object of this invention to provide more versatile gun mounting structure for armed vehicles.
It is another object of the invention to provide for a lower silhouette combat vehicle without sacrificing firepower effectiveness.
It is a further object of the invention to provide for a broad gun traverse angle in low profile combat vehicles.
It is still another object of the invention to reduce the vulnerability of armed military vehicles to enemy obsernited States Patent vation and enemy fire while retaining optimum operational capabilities.
It is still a further object of the invention to provide for selective control of the height of a gun mounted on a vehicle.
The invention, together with further objects and advantages thereof, will best be understood by reference to the accompanying drawings, of which:
FIG. 1 is a perspective view of an armored track-type military tank designed to have a minimized height and embodying the present invention therein; and
FIG. 2 is an elevation section view showing the principal armament and associated support and turret structure of the vehicle in FIG. 1.
Referring now to the drawing and more particularly to FIG. 1 thereof, there is shown a military combat vehicle 11 of the class having an armored body 12 and riding on articulated endless tracks 13 at each side thereof. The vehicle body 12 is formed with a sloping top surface 14 at the forward end and a slightly more elevated and horizontal rearward top surface 16 connected thereto by a more sharply sloping transition section 17. Vehicle 11 is provided with the customary appurtenances including an entry hatch 1S and commanders station 19 with periscopes 21 on the rearward top surface 16. An engine cover 22 and drivers station 23 with periscopes 24 are situated on the forward top surface 14. Automatic gun ports 25 are distributed along the sides of the vehicle body 12.
The vehicle 11 has been designed throughout to achieve an extremely low profile and consistent with such purpose the principal armament, which is a cannon 26 in this embodiment, is mounted above the forward top surface 14 by means to be herein described which provide for raising or lowering the gun relative to the vehicle body ].2 as desired.
Cannon 26, which may be a high muzzle velocity rifle and which has a parallel machine gun 27 secured thereto, projects from a rotatable cylindrical turret 28 situated above the vehicle body top surface 14. Rearward top surface 16 and transition section 17 of the vehicle body 12 extend forwardly behind the turret to enclose the rear half of the side wall thereof when the turret is in its lower position.
Considering now the structure of the gun and turret support mechanism, with reference to FIG. 2, a well which receives the lower end of the turret 28 is formed by an annular member 29 secured to the vehicle top surface 14. The turret has a rotatable circular baseplate 31 journalled coaxially within the lower end of the annular member 29 by a bearing 32.
An annular outer sidewall 33 of the turret 28 is secured to baseplate 31 and a circular turret cover 34 is disposed above the outer sidewall and rests thereon when the turret is in its lowermost position so that the top surface of the turret is substantially continuous with the rear top surface 16 of the vehicle at such time. To provide for the desired vertical telescoping movement of the turret 28, an annular inner sidewall 36 extends downwardly from cover 34 within outer Wall 33, the inner sidewall being secured to the cover. A slot opening 37 is provided through the forward portions of outer sidewall 33, inner sidewall 36 and cover 34 to allow the cannon 26 to project from the turret and to provide for vertical pivoting of the gun.
Traverse of the cannon 26, including the turret 28, is effected by a reversible electrical motor 38 secured to the vehicle and having a drive gear 39 which engages gear teeth 41 on a flange 42 which projects from the rim of the turret baseplate 31.
A vertical tubular gun support post 43 is transpierced through the turret baseplate 31 near the edge thereof and on the opposite end of the turret from the gun port opening 37. Post 43 is movable in a vertical direction and a bearing 44 is disposed therearound at baseplate 31 to facilitate such movement. A fork 46 at the upper end of post 43 inclines towards gun port 37 and the breech casing 5d of cannon 26 is pivoted to the fork for movement in a vertical plane. A hydraulic jack 45 is connected between post 43 and the breech casing 50 of cannon 26 to control such movement. A member 47 connects fork 46 with the inner sidewall 36 of the turret so that upward movement of the post 43 carries the inner sidewall and turret cover 34 upward along with the cannon 26.
Considering now the mechanism for controlling the vertical position of turret 23 and cannon 26, post 43 extends downward from the turret baseplate 31 within a vertical tubulation 48 formed as part of the baseplate and is engaged therewith by splines 49 which prevent the post from rotating about its own axis while permitting the desired vertical movement. The base of the tubulation 48 is bolted to a circular turntable 51 which is situated immediately above the floor 52 of the vehicle and which is turnable about the rotary axis of the turret 28. A hydraulic jack 53 is disposed within the lower portion of the post 43 and is pivotably coupnzd at the lower end to the turntable 51.
The extensible rod 54 of jack 53 is directed upwardly within post 43 and is pivotably coupled thereto by a cross-pin 56. Extension of the jack 53 thus acts to raise the cannon 26 together with the turret cover 34 and inner sidewall 36.
In operation, the several controls for loading, aiming and firing the cannon 26, including controls for the hydraulic jack 53, are operated remotely by a gunner by means understood within the art. With the cannon 26 fully lowered, the turret 28 is not significantly higher than the top surface 16 of the vehicle. In the lowered position and with the cannon 26 horizontal, the gun may still be traversed through a wide angle, 115 in either direction in one embodiment of the invention, and may be traversed a full 360 if it is inclined sufficiently to clear the hull to the rear. Whenever it becomes tactically desirable, the cannon 26 together with turret 28 may be lifted by actuation of jack 53. In the raised position the cannon 26 may be rotated 360 while in a horizontal position and may be depressed below horizontal when directed substantially forward.
While the gun mounting has been described with reference to an armored track type vehicle and a specific type of gun, it will be apparent that the invention is equally applicable to other forms of armed vehicle and to the mounting of a variety of guns or the like.
What is claimed is:
1.
