    20 25 30 35 534 D44 2 with wheels that can be lowered to the ground with hydraulic means.
    These wheels can be lowered when the howitzer is supported. The hubits can be supported, for example, by the operating crew holding the cannon tube at the mouth end. The front and rear trailer legs are articulated so that they can be lifted above the ground to a position substantially above the spinning platform when the wheels support the howitzer.
    When the wheels are arranged in this way and when the front and rear legs are lifted off the ground, the howitzer is in the transport position.
    In any case, it is desirable to be able to switch between the firing mode and the transport mode in as short a time as possible and with the use of as little manpower as possible. Lowering the wheels is a particularly time-consuming process.
    It is therefore an object of the present invention to provide a howitzer which is configurable between a firing mode and a transport mode in a short time and by means of as little operating crew as possible.
    Thus, a towed howitzer is provided configurable between a transport mode and a firing mode, the towed howitzer being adapted for placement on a ground plane, the towed howitzer comprising: a cannon tube for firing a projectile, the cannon tube defining a cannon tube, the cannon tube at an azimuth and an elevation, a sight means for varying the cannon tube elevation and azimuth, a front leg comprising a wheel for contact with the ground at a front ground contact point for supporting the sight means, a suspension system for resiliently clamping the wheel, a restraint means for activating the suspension system , a hind leg for contact with the ground 10 15 20 25 30 35 534 044 3 at a rear ground contact point, and wherein the hind leg comprises a joint for pivoting the hind leg out of contact with the ground, the suspension system being locked and the hind leg being in contact with the ground at the rear the contact point in the firing mode, and wherein the hind leg is lifted from the rear contact point and the suspension system is mounted in the transport mode.
    Advantageously, this provides a device that can be quickly converted between a firing mode and a transport mode because the wheels are in contact with the ground in both modes. Furthermore, since the wheels are the main ground contact points of the howitzer base and also react against the firing forces, they can play the same role as the front legs according to the prior art. This has the effect that the need for front legs which are arranged solely to counteract firing forces disappears. On the other hand, this simplifies the conversion procedure because only the hind leg (or hind legs) need to be swung over.
    Preferably, the hind leg is accompanied by the joint in such a way that the hind leg can rest over the cradle.
    Advantageously, this allows the howitzer to be folded in to create a compatible device in the transport mode.
    Preferably, the hinge comprises a first hinge defining a first hinge axis and a second hinge defining a second hinge axis, the first hinge axis and the second hinge axis being substantially perpendicular.
    Advantageously, this guide arrangement can give the hind leg two degrees of freedom so that it can be swung out wide to provide a wide base in the firing mode but also swung back to provide a compact unit in the transport mode. Preferably, the hind leg has an elongate shape defining a hind leg axis, the first hinge axis being offset from the hind leg axis towards the center line of the howitzer, the first joint thereby determining the inclination of the hind legs relative to the center line.
    Displacement of the first joint towards the center line means that the driver only needs to turn the hind leg over the azimuth center line and then turn it around the second joint to store the hind leg over the cradle. Advantageously, this is a quick and easy maneuver which allows the crew to unfold or rewind the howitzer with reduced effort.
    Preferably, the sight means comprises pin holes and the hind leg comprises a pin, the pin being located at substantially the same point on the hind leg axis as the first joint and laterally offset from the hind leg axis away from the centerline of the howitzer so that the pin engages the pin hole to secure the hind leg when the hind leg has maximum inclination. to the center line.
    Advantageously, this provides a robust way of securing the hind leg in place to anticipate the large forces it must withstand when firing.
    Preferably, the gun barrel comprises a mouth, the mouth having a bracket for forming a connection to a towbar eye.
    The provision of the muzzle bracket not only saves time for connecting the howitzer to the vehicle but also means that if a howitzer is in the firing state, the muzzle bracket can be used to simplify the changeover to the transport mode. This simplification is made by lowering the inclination of the gun barrel, connecting the muzzle bracket to the towing hook of the towing vehicle, in which state the vehicle can be driven forward a short distance to disengage the hind legs from their ground contact point whereupon the hind legs can be folded over to transport.
    Preferably, the wheel suspension comprises a wheel arm, connecting the wheels to the front leg, and pivotable about a resilient bracket, a recess in the wheel arm, and the suspension limiting means comprises a tongue for engaging the recess to prevent pivoting of the wheel arm around the resilient bracket.
    Advantageously, this can provide a robust mechanism for selectively engaging the suspension. This is necessary to withstand the forces generated by the firing.
    Preferably, the wheel arm is resiliently attached to a telescopic arm such that the tongue engages the recess when the telescopic arm is extended and the tongue is disengaged from the recess when the telescopic arm is inserted.
    Advantageously, this provides a device that can be easily converted from transport mode to firing mode because a single maneuver (ie extension of the telescopic arm) simultaneously locks out of the suspension and expands the ground contact area. This gives rise to a stable firing platform in a short time and by simple operation. Similarly, if the howitzer is in the firing position, the insertion of the telescopic arm applies the suspension to quickly prepare the howitzer for transport.
    According to another aspect of the invention, there is provided a method of converting a towed howitzer from a transport position to a firing position, the towed howitzer comprising a gun barrel for firing a projectile, the gun barrel defining a gun barrel shaft, a gun barrel shaft, a cradle for holding the cannon tube at an azimuth and an elevation, a recoil receiving mechanism such that the cannon tube is movable along the cannon tube axis relative to the cradle, a means for varying the cannon tube elevation and azimuth, a front leg comprising a wheel for contact with the ground at a front ground contact for supporting the sighting means, a suspension system for resiliently clamping the wheel, a suspension limiting means, a rear leg for contact with the ground at a rear ground contact point, the rear leg comprising a hinge for pivoting the rear leg out of contact with the ground, the method comprising the steps of pivoting the rear leg around the hinge s moving the hind leg from a rest position over the cradle to a position where the hind leg is in contact with the ground at the rear contact point, and applying the suspension limiting member.
    Advantageously, this method eliminates the time consuming steps of the prior art where wheels must be lowered and front legs must be folded over when transitioning from a firing mode to a transport mode. By eliminating the need for these three stages, the present invention tends to be configured between states for a shorter time and / or using less manpower.
    According to another aspect of the invention there is provided a howitzer comprising a wheel axle member on which a first wheel and a second wheel are mounted, the first and second wheels being arranged for contact with the ground at a first front point and a second front point, at least two hind legs for contact with the ground at rear contact points, the wheel axle member being selectively pivotable about a pivot axis projecting from a strut on the howitzer so that both the first wheel and the second wheel may be in contact with the ground at an interval of slopes lateral to the howitzer. 10 15 20 25 30 35 534 044 Advantageously, such a howitzer can support itself by four ground contact points regardless of the topography of the ground from which it is to be fired. Because both wheels are in contact with the ground, a stable firing base is provided which maintains the precision of the artillery piece, distributes the load more evenly along the main structure and improves the stability so that the probability of the main object tipping over is reduced.
    An example of one embodiment of the invention will now be described with reference to the following figures, in which: Figure 1 shows the lateral inclination of a typical howitzer resting on a ground surface, the howitzer being in firing mode.
    Figure 2 shows the howitzer according to figure 1 arranged in the transport mode.
    Figure 3 is a top view of the howitzer according to Figure 1 with, for illustrative purposes, one wheel arranged for transport and the other arranged for firing.
    Figure 4 is a perspective view, partly in section, of the joint between the hind leg and the sight mechanism.
    Figure 5 is another perspective view of the joint and sight mechanism such that the pin hole and pin can be clearly seen.
    Figure 6 is a top view of a suspension locking mechanism for the howitzer according to Figure 1. Figure 7 is a side view of a suspension locking mechanism for the howitzer according to Figure 1.
    Figure 8 is a perspective view substantially from the front of another howitzer which has wheel axle means arranged for contact with flat ground.
    Figure 9 is a perspective view substantially from the front of the howitzer according to Figure 8 arranged for contact with inclined ground.
    Figure 10 is a perspective view substantially from above of a portion of the howitzer of Figure 8.
    With particular reference to Figures 1, 2 and 3, the howitzer with reference numeral 100 will be described. A gun barrel 2 is shown which defines a gun barrel shaft 3. The gun barrel 2 has a mouth end 2a and a rear end 2b. A muzzle bracket 2c extends from the gun barrel 2 at the muzzle end 2a. The gun barrel 2 is inclined to a ground plane 1 with a certain slope a and is inclined to the paper plane a certain azimuth. In Figure 1, the slope is approximately 35 ° and the azimuth is zero. In Figure two, the slope is approximately zero and the azimuth is zero. In Figure 3, the azimuth is zero.
    The gun barrel 2 is held in a position by the cradle 4 which encloses the shaft of the gun barrel 2 in an area at the rear end 2a. the cradle 4 is provided with a recoil mechanism (not shown) so that the cannon tube 2 can move backwards through the cradle 4 along the cannon tube axis 3 when a projectile 5 (55mm caliber firing salvo) (for example one is fired, the recoil mechanism also reacting to the launch of the projectile 5). the cradle 4 is connected to sight means 7 for changing the inclination and azimuth of the gun barrel 3. With further reference to Figures 4 and 5, the sight means 7 is connected to a component on a front leg 10 through a first pivotable joint 11 and is connected to a hind leg 12 by a second pivotable joint 13. On the opposite side of the howitzer 100 shown in Figures 1 and 2, a second front leg 210 is connected to the pivot body 8 via a second pivotable joint 211 and a second hind leg 212 is connected to the pivot body 8 via a further pivotable joint 213.
    The front leg 10 defines a front leg shaft 41 and includes a sleeve 34 coaxially disposed along the front leg shaft 41 with a telescopic arm 36. The sleeve 34 and the telescopic arm 36 are slidably connected; a portion of the telescopic arm 36 lies within the sleeve 34. The sleeve 34 is the component of the front leg 10 which is connected to the first pivotable joint 11.
    The sleeve 34 on the front leg 10 is connected to the sleeve on the opposite front leg 210 by a strut 44 so as to create an H-shaped support. The wheel 32 rests on the ground 1 at the front contact point 28. The wheel 32 has a suspension mechanism 62.
    The suspension mechanism 62 can be locked by suspension limiting means 72.
    Referring to Figures 6 and 7, the wheel 32 is mounted on one end of a wheel arm 65 so that the wheel 32 can rotate freely. The opposite end of the wheel arm 65 is connected to the telescopic arm 36 by a resilient interface 67. The resilient interface 67 allows the wheel arm 65 to rotate around the resilient interface 67 but is loaded to return the wheel arm 65 to an equilibrium position. This affects the suspension when the howitz is in transport mode. The wheel arm 65 includes a recess 66 for housing a tongue 68. The tongue 68 is projected from the suspension limiting member 72. The suspension limiting member 72 is provided as a rod 71 pivotally mounted on the extendable telescopic arm. 36 and the strut 44 so that the tongue 68 does not engage the recess 66 when the telescopic arm 36 is pushed in.
    When the tongue 68 is housed in the recess 66, the wheel arm 65 is restricted from rotating around the resilient interface 67.
    The recess 66 and the tongue 68 are tapered so that the tongue 68 can be inserted into the recess 66 in a range of equilibrium positions.
    A manual gear 40 is connected to a drive wheel 43 via a gear in the front leg 10 for extension and insertion of the telescopic arm 36.
    The hind leg 12 includes an elongate member 22 extending downwardly and rearwardly from the second pivotable joint 13 to a surface for contacting the ground 14 (such as a shovel). Thereby, the hind leg 12 rests against the ground 1 at a rear ground contact point 73. The extended part 22 defines a hind leg axis 24.
    The hind leg 12 further comprises a joint, which in Figure 1 is indicated by reference numeral 54. The joint 54 comprises the second pivotable joint 13. The second pivotable joint 13 allows the hind leg 12 to pivot around the sighting means 7.
    The joint 54 also includes a pivot joint 58 defining a pivot axis 56. The pivot joint 58 determines the extent of the hind leg 12, the extent being the inclination of the hind leg axis 24 relative to the azimuth centerline (the azimuth centerline is coaxial with the cannon tube axis 3 in Figure 3). The hinge shaft 56 is generally perpendicular to both the hind leg shaft 24 and a pivot shaft 57 defined by the second pivot joint 13. The hinge shaft 56 is offset from the center of the elongate portion 22 toward the azimuth centerline.
    A coupling mechanism, shown in Figure 1 by reference numeral 52, is provided at an interface between the hind leg 12 and the sight member 7. As clearly shown in Figures 3 and 4, the coupling mechanism 52 includes a pin 51 and a pin hole 53. The pin 51 is located on the hind leg 12 on substantially the same place on the hind leg shaft 24 as the joint 58 but offset towards the opposite side (ie away from the azimuth centerline). When they completely grip each other, the pin hole 53 and the pin 51 can be further fastened by passing a bolt (not shown) through both the pin hole 53 and the pin 51. With the bolt in place, the hind leg 12 cannot pivot around the joint 58.
    The hubits 100 are configurable from the transport mode shown in Figure 2 to the firing mode shown in Figure 1.
    In the transport mode, the telescopic arm 36 is in a retracted condition so that the tongue 68 and the recess 66 are disengaged and the suspension mechanism 62 is thus applied.
    The hind legs 12 also rest over the cradle 4 in the transport mode. In the transport mode, the muzzle bracket 2c of the howitzer 100 can be attached to a towing hook on a towing vehicle (not shown).
    To configure the howitzer 100 from a transport mode to a firing mode, the front leg 10 should be extended to move the front ground contact point 28 forward to increase the resistance to tipping over and for the tongue 68 to engage the recess 66; this limits the suspension 62 to provide a stable firing base. The front leg 10 is extended through the gear 40 which is connected to a gear 43 via a gear in the front leg 10.
    The rear leg 12 should also be pivoted around the second pivot joint so that it can rest against the ground. The hind leg should also be widened by moving it away from the azimuth center line by pivoting it around its joint 58.
    When fully extended, the pin hole 53 engages the pin 51 and can be further secured with a latch if required. at full development, the surface 14 of the hind leg 12 rests against the rear ground contact point 73.
    When the rear leg 12 is extended, the howitzer 100 can be disconnected from the towing vehicle by releasing the muzzle bracket 2c from the towing hook.
    The rear leg 12 should be securely attached to the ground 1. The portions of the rear leg 12 with ground contact are therefore dug into the ground by some combination of the towing vehicle, the control personnel, and by the recoil force when the first shot 5 is fired from the howitzer 100.
    Alternatively, the howitzer 100 may be provided with a pivoting mechanism 300 as shown in Figures 8, 9 and 10. The pivoting mechanism 300 may incorporate a selectively applied wheel suspension. The pivot mechanism 300 acts as a pivotable wheel axle.
    The pivot mechanism 300 includes a center housing 301 rotatably mounted on a pivot shaft 302 extending from the strut 44 so that the housing 301 can pivot about the pivot shaft 303. The pivot shaft 303 is substantially perpendicular to the tangent to the arc of the strut 44. Two substantially coaxial suspension bracket arms 304a and 304b extend laterally from the center housing 301. A first suspension bracket arm 304a extends to adjacent wheels 534 and 13 wheels 32 and a second suspension bracket arm 304b extends to spacer wheels 232.
    Each suspension bracket arm 304a and 304b has an elongate shape and thus defines a suspension bracket shaft (not shown). Each suspension bracket arm 304a and 304b is connected to the housing 301 via a joint (not shown) which allows each arm to pivot about its respective suspension bracket axis to a limited degree and also to swing up and down from the joint to a limited degree.
    The suspension clamp arms 304a and 304b tend to rotate with the housing 301 retaining their coaxial configuration.
    Dampers 305a and 305 extend between the base of the housing 301 and the respective midpoints of the suspension bracket arm 304a 304b. Each damper 305a and 305b is connected to the housing 301 and the respective center points 307a, b by joints which allow some degree of pivot about a damper axis as well as fluttering movements.
    A piston 306 for enabling pivoting is connected between the housing 301 and the sight means 7. The configuration of the piston 306 determines whether the housing 301 can pivot freely around the strut 44. When the piston 306 is locked, the housing 301 cannot pivot. When the piston 301 is free to extend and contract, the housing 301 can pivot. The ends of each suspension bracket arm facing away from the housing 301 are pivotally connected to a piston pin 306a, 306b which extends from arm 36, 236.
    The piston pins 306a, 306b are pivotally connected to arms 36, 236. Wheels 32, 322 rotate about a bearing (not shown) arranged on the piston pins 306a, 306b.
    The pivoting mechanism 300 can be activated by unlocking the piston 306 so that the housing 301 can pivot freely about the pivot shaft 303. The wheel shaft (defined by the substantially coaxial suspension brackets 304a and 334b) is then free to pivot about. the pivot shaft 303 so that each wheel can be in contact with the ground to support the cannon and support the firing forces if the howitzer is not placed on completely smooth ground.
    In use, the housing 301 pivots automatically depending on the weight of the howitzer 100 when the piston 306 is unlocked so that both wheels 32 and 232 come into contact with the ground. both wheels 32 and 232 are in contact with the ground, the dampers 305a and 305b should be attached so as not to affect the firing. This can be accomplished by locking the dampers 305a and 305b in place before firing, or alternatively by allowing the dampers to lock automatically when at short-term forces (as experienced during firing) but allowing long-term movements (such as the weight of the howitzer 100) and medium forces (such as experienced when the dampers and piston act as a selectively applied wheel suspension system).
    The components of the hubits are made of materials that can withstand maximum stresses and cyclic loads as experienced during use. In relation to this, the shape of the components is selected according to the same criteria.
    The materials and shapes are chosen to minimize weight without compromising strength. Given this, for example, various steel alloys, compositions and titanium may be suitable materials. Those skilled in the design of howitzers would be able to determine which materials and shapes would be best for the circumstances.
    While the above example specifically relates to a 155 mm caliber shotgun ointment, the invention is in no way limited to a particular caliber. For example, a howitzer of the present invention can be used to fire 105 mm volleys of ammunition. It is further contemplated that howitzers within the scope of the claims of the present invention may be designed to be suitable for disassembly and assembly. parts that can be replaced individually without the entire howitzer having to be taken out of service.
    Additional variants within the scope of the present invention would be apparent to those skilled in the art.
