Description

Arm Cylinder Integral Pressure Suspension System for Tank

The present invention relates to an arm pressure-integrated organic suspension device for a tank arm cylinder, and more particularly, in the minimum required space while being mounted to perform a spring and damping function by interlocking with a road wheel of a large combat vehicle such as a tank. The present invention relates to an arm cylinder integrated organic pressure suspension unit (HSU) that can be mounted and operated.

Today, with the rapid development of high technology, the effects are spreading throughout the industry, which is no exception to the military sector. So state-of-the-art equipment is being applied to military installations and equipment, as is the case for armored equipment, the mainstay of ground warfare.

As such, the advancement of the warfare capability inevitably required the improvement of performance even in the case of a combat vehicle, but in particular, in the case of a tank such as a tank that requires both protection and maneuverability, there is a certain limitation in improving the performance.

In other words, the protection performance of the tank is closely related to the strength of the tank shell, such as the thickness of the armor of the tank. On the contrary, the mobility is inversely proportional to the thickness of the tank armor. Combat vehicles always have difficulty in pursuing improvements in strength and maneuverability at the same time, and the present invention also focuses on these problems that occur with respect to the suspension of the tank.

Hereinafter, the above-mentioned problem will be described in more detail with reference to the drawings. The conventional tank 301 schematically showing only the lower body portion in FIG. 1 has the caterpillar 305 wound around the plurality of bogie wheels 303 at the rear. It is advanced by rotating with the mounted drive wheel 307, where the bogie wheel 303 is equipped with a suspension device 309 for spring and damping action, respectively.

Here, the suspension device 309 is, as shown in Figure 2, the housing block 313 which is fastened by bolts 311 at the bottom of both sides of the tank, the upper end inserted into the housing block 313 and The lower cylinders 315 and 317 and the upper cylinder 315 are divided into a nitrogen chamber 319 and a hydraulic oil chamber 321, and are inserted into the floating piston 323 and the lower cylinder 317, which are inserted to slide therein. A piston 327 which is slid left and right by 325, a damper 328 for fluidly connecting the inside of the hydraulic oil chamber 321 of the upper cylinder 315 and the lower cylinder 317, and a connecting rod at one end ( A spline attached to the crank portion 331 through a crank portion 331 through which the piston 327 is connected and attached to the other end with a spline shaft 329, and a spline hole 333 penetrated through one end 325. The rod wheel spindle is engaged with the shaft 329 and is opened on the other end ( 335 is comprised by the arm 339 by which the bogie wheel 337 is supported and fixed.

Therefore, the suspension device 309 is rotated counterclockwise as shown by the arm 339 when the bogie wheel 337 is raised in accordance with the road surface conditions when the tank 301 is running, the splines (329,333) The crank portion 331 is rotated counterclockwise by matching. When the rotational force of the crank portion 331 is applied to the piston 327 through the connecting rod 325 to pressurize the hydraulic oil inside the lower cylinder 317. The hydraulic pressure of the pressurized hydraulic oil passes through the damper 328 and acts on the upper cylinder 315 to compress the nitrogen gas on the nitrogen chamber 319 side through the floating piston 323.

In this state, when the tank 301 reaches the flat surface, the upstream load acting on the bogie 337 disappears and the compressed nitrogen gas and the hydraulic oil expand so that the bogie 337 elastically returns to its original shape. 309 makes it possible to flexibly maintain the bogie 337 as if it were a damper spring of an automobile suspension.

If the bogie 337 rises rapidly, the pressure applied to the damper 328 also rises rapidly. At this time, the damper 328 is a damper-specific function to alleviate this sudden pressure rise, thereby damping the automobile suspension. Will perform the same function.

However, as shown in FIG. 3, the conventional suspension device 301 is equipped with an arm 339 in a state of being completely exposed to the outside of the housing block 313 and the arm 339 through the rod wheel spindle 335. The bogie 337 is mounted on the outside of the arm, where the arm 339 is large despite being made of super high strength nickel chromium molybdenum steel (SNCM), a common material used for tank structures. In the case of a tank, the ground load is huge enough to reach 24 tons when operating from 6 ton when stopped, so that the overall strength is maintained by increasing the manufacturing dimensions such as thickness and width.

As such, as the arm 339 increases in size, the suspension device 309 has a total weight of approximately 300 kg per component, and the width of the transverse width excluding the bogie wheel 337 is about 280 as shown in FIG. 3. Increased to mm. Accordingly, when considering the entire tank 301 having a plurality of suspension devices, the increase in the gross weight cannot be avoided, which results in deterioration of maneuverability for increasing protection or durability as mentioned above. . Similarly, the increase in the lateral width of the suspension device 309 reduces the space inside the tank such as the control chamber when comparing tanks having the same external dimensions, resulting in a reduction in the amount of shells or fuel, which weakens the thermal power and maneuverability. Brought it.

As described above, in the tank, the relationship between durability, protection, and maneuverability is opposed to each other. In particular, in the case of the suspension device, there are problems of strength and volumetric efficiency. Accordingly, an object of the present invention is to increase durability and increase maneuverability of a suspension device by not causing a reduction in volume efficiency due to the suspension device without causing a problem in strength to the suspension device. .

In other words, by integrating the function of the arm supporting the bogie wheel of the tank into the housing block, the suspension device can be compacted by eliminating the need for a separate arm, while maintaining the bogie support durability by the arms of the conventional suspension device. The purpose is to increase the available space and reduce the overall weight and ultimately improve the maneuverability of the tank.

Therefore, in order to achieve the above object, the present invention provides a motor-driven housing means in which a reciprocating means for generating an organic pressure is formed therein and a rod wheel spindle fastening portion for fixing and supporting the bogie wheel is externally attached. A buffer means for fluidly connecting with the reciprocating means of the means to relieve a sudden induced pressure, a link means for transmitting the movement of the reciprocating means to the electric combined housing means, and a rotation center of the link means and the electric combined housing means And it is to provide an arm cylinder type organic pressure suspension device for a tank composed of a fixed shaft means that these means are coupled.

In addition, in the above-mentioned arm cylinder-integrated organic pressure suspension device for tanks, the electric and housing means has a through hole for forming an upper chamber therein, a blocked hole for forming an interruption chamber, and a blocked hole for forming a nitrogen chamber. And one end of the closed hole provides a tank-integrated organic pressure suspension device for a tank including an arm portion in which an airtight plug is press-fitted.

In addition, a reciprocating means for generating an organic pressure is formed therein, and a motor-driven housing means having a rod wheel spindle fastening portion attached to the outside for fixing and supporting the bogie wheel, and transmitting the movement of the reciprocating means to the motor-driven housing means. A tank arm cylinder type organic pressure suspending device, comprising a link means, which is a rotational center of the link means and the electric and housing means, and which means are coupled and mounted, wherein the reciprocating means of the electric and housing means It is an object of the present invention to provide a tank-integrated organic pressure suspension device for a tank, which is a hydraulic oil flow chamber made of a manifold having a hydraulic chamber and upper and lower flow paths for inflow and outflow in fluid connection with a fluid.

As described above, the cylindrical upper and lower chambers 11 and 13 are formed, and the piston 15 is slidably inserted into the upper chamber 11 so as to slide left and right, and in the lower chamber 13 a floating piston ( 17 is likewise inserted reciprocally.

In this way, the cylinder piston structure 10 is formed in the housing block 20, in which the space between the piston 15 and the screw cap 31 in the upper chamber 11 is provided with the hydraulic oil supply pipe 22 shown in FIG.

On the circumferential surface between the bearing mounting surfaces 59 and 61 of the mount spindle 55, an external tooth spline 63 is formed that is matched with an internal tooth spline formed in the spline hole 47 of the crank part 49. As shown in FIG.

As a result, the mount spindle 55 becomes the center of rotation of the housing block 20 which rotates up and down in accordance with the shanghai movement of the bogie 3 because the crank part 49 is fixed without changing the rotational phase at a set angle. .

By the way, the flat plate-type mount 53 is a bearing mounting as shown in FIG. 11 as another embodiment when the shaft hole 21 of the housing block 20 is protruded as shown in FIG. In the annular portion where the surface 59 and the spindle 55 are in contact with each other, the clearance groove 65 of an appropriate depth may be engraved.

The damper 70 shown in more detail in FIGS. 12 to 16 constitutes a normal hydraulic transmission circuit in a normal state, and constitutes a hydraulic buffer circuit that combines hydraulic transmission and buffering under abnormal high pressure. It consists of the manifold 73 and the resonance valve 75 and relief valve 77 which are attached in the manifold 73 inside. As can be seen in FIG. 12, the manifold 73 is fastened with bolts coupled to the bolt holes 74 on the sides of the housing block 20.

In addition, a plug 76 is fitted to the upper end of the hydraulic chamber 71, and a cylindrical protrusion 94 into which the relief valve 77 is inserted protrudes from the bottom thereof.

A spring valve 75 pressurized upward by the spring 84 is inserted.

The valve portion 75 has a head portion 89 formed at a lower end thereof, and an enlarged diameter portion 93 is formed at the lower edge portion of the guide 87 in contact with the inclined surface 91 of the lower head portion 89. . A recess 90 is machined between the bouncing valve 75 and the circumferential surface of the hydraulic chamber 71. The upper end of the recess 90 communicates the silencer flow path 81 with the hydraulic chamber 71. The main orifice 80 is penetrated.

The resonance flow path 81 communicated with the hydraulic chamber 71 by the orifice 80 has a U-shape, and has an upper flow path 81-1, a lower flow path 81-2, and a longitudinal flow path 81. -3). Each of the flow paths 81-1,-2,-3 is penetrated from the wall surface of the manifold 73 so that the end portion is sealed by the plug 82.

FIG. 14 shows a cross section taken along the line BB of FIG. 16, on which a rebound flow path 83 of inverse letter shape is formed. Also in this flow path 83, the upper flow path 83-1 is connected with the recessed part 90 of the hydraulic chamber 71, and the tip part is sealed by the plug 86. As shown in FIG. A relief valve 77 is inserted and mounted in the relief valve chamber 95 formed in the lower flow passage 83-2 connected to the upper flow passage 83-1 through the longitudinal flow passage 83-3. At the end of (83-2), a guide (96) serving as a seal and a relief valve (77) guide is inserted.

15 is a cross-sectional view taken along the line CC of FIG. 16, in which the upper and lower openings 77 and 79 are formed on the mounting surface of the housing block 20 of the manifold 73. have. The upper opening 77 communicates with the upper portion of the hydraulic chamber 71 through the hydraulic oil hole 88, and the lower opening 79 directly communicates with the lower portion of the hydraulic chamber 71.

Another embodiment of the present invention is a tank-integrated organic pressure suspension device 100 for a tank as shown in FIG. The suspension device 100 according to the present embodiment has the same configuration as the first embodiment except for the housing block 120.

In the arm part 133 of the housing block 120 according to the second embodiment, in addition to the through hole 127 at the top and the blocked hole 129 at the middle, one more hole 130 at the bottom is opened. It is. The through hole 127 at the top and the closed hole 129 at the middle form the top chamber 111 and the stop chamber 113, respectively. The lower end of the closed hole 130 is sealed with an airtight plug 134, and the lower chamber 114 formed in this way is nitrogen gas supplied from the nitrogen filling port 138 through the orifice 136. Is filled, the interruption chamber 113 and the lower chamber 114 is connected to the communication flow path 140, so as to act as one chamber, it is possible to increase the volume of the nitrogen chamber.

Another embodiment of the present invention is shown in FIG. As shown in the figure, the tank arm cylinder-integrated organic pressure suspending device 200 according to the third embodiment of the present invention is the same as most of the configuration of the suspension device (1,100) of the first or second embodiment, The only difference is that the hydraulic oil distribution means, that is, the hydraulic oil flow chamber 270 is mounted instead of the shock absorbing means, that is, the damper 70. Accordingly, the organic pressure suspension device to which the hydraulic oil flow chamber 270 is coupled is mounted on the bogie wheel to have only a spring action.

The hydraulic oil flow chamber 270 is fastened by bolts coupled to the bolt holes 275 penetrating the side of the housing block so as to be in fluid communication with the piston cylinder structure of the housing block, similar to the damper 70 of the first embodiment. In the manifold 270 forming the body of the hydraulic oil flow chamber 270, the hydraulic chamber 271 is opened in the longitudinal direction of the body. A sealing plug 276 is press-fitted to the upper opening of the chamber 271, and an upper flow passage 272 communicating with the upper chamber of the first or second embodiment is horizontally opened below the plug 276. In the lower part of the upper flow path 272, the lower flow path 274 communicating with the lower chamber 13 in the first embodiment and the stopping chamber 113 in the second embodiment is parallel to the upper flow path 272. It is laterally opened.

The tank-integrated organic pressure suspension device for a tank of the present invention has the configuration as described above, and performs the suspension operation of the bogie wheel as follows.

19, the first embodiment of the present invention is shown in a partially omitted state. As shown, the housing block 20 of the suspension device 1 according to the first embodiment of the present invention has a tank in a stationary state or a tank running. When the road surface is a flat surface, as shown in Fig. 1, the line connecting the center point of the mount spindle 55 and the center point of the load wheel spindle 7, that is, the axis of the suspension device 1 is inclined about 30 ° downward with respect to the horizontal plane. Lost This state is called a static state. At this time, the piston 15 and the floating piston 17 are located at the center left of the upper chamber 11 and slightly to the right of the center of the lower chamber 13, respectively. 15) and the right side of the floating piston 17 are filled with hydraulic oil, and the left side of the floating piston 17 is filled with nitrogen gas filled gas.

20 shows the full jounce state of the suspension device 1. In this state, the axis of the suspension device 1 is inclined upward by approximately 18 degrees with respect to the horizontal plane, and the bogie wheel 3 ascends as much as possible from the side of the body of the tank. In addition, the piston 15 is located at the right end of the upper chamber 11, the floating piston 17 is located at the left end of the lower chamber (13).

Finally, in the full rebound state as shown in Fig. 21, the suspension device 1 has an angle of inclination of the axis along which the bogie 3 extends farther away from the tank body and forms a horizontal plane. It will reach about °. At this time, the piston 15 is located at the left end of the upper chamber 11, the floating piston 17 is located at the right end of the lower chamber (13).

Therefore, when an upward load is gradually applied from the road surface to the bogie wheel 3 in the stationary state shown in FIG. 19, the housing block 20 rotates counterclockwise to the full-union state shown in FIG. 20. At this time, since the crank part 49 pin-coupled to the connecting rod 43 is splined to the mount spindle 55 and rotational movement is suppressed, the piston 5 connected to the connecting rod 43 is the upper chamber 11. The hydraulic oil filled in the) is pressurized to the right.

The pressurized hydraulic oil is introduced into the hydraulic chamber 71 of the damper 70 through the hydraulic oil hole 88 shown in more detail in FIG. 15 via the screw cap 31 shown in FIG. 9. The introduced pressurized oil exits into the recess 90 through the opposite hydraulic oil hole 88 'and the hydraulic oil holes 92 and 92' shown in FIG. The hydraulic oil delivered to the upper passage 81-1 through the recess 90 flows into the lower portion of the hydraulic chamber 71 via the longitudinal passage 81-3 and the lower passage 81-2. Here, the hydraulic oil flows into the lower chamber 13 of the housing block 20 through the lower opening 79 shown in FIG. 15 and presses the floaty piston 17 to the left end. At this time, since the hydraulic oil applied to the rebound flow path 83 acts inside and outside the valve 77 through the orifice 99 of the relief valve 77, the valve 99 is not moved and is blocked at this point.

Therefore, when the bogie wheel 3 returns to the normal state again on the flat surface from the jauns state, the hydraulic oil is reduced by the expansion and repulsion force of the nitrogen gas compressed by the floating piston 17 inside the lower chamber 13. Since the return to the upper chamber 11 along the furnace, the suspension device 1 is elastically returned to its original shape.

On the contrary, when the upward load acting on the bogie 3 is sharply increased, the pressure of the hydraulic oil is rapidly increased along the inclined surface of the head portion 89 of the jaw valve 75 and the enlarged diameter portion of the edge of the guide 87 is increased. Downward pressing force is generated by the cross-sectional area difference caused by 93, and the spring valve 75 is pushed down while the spring 84 is compressed. In this case, the hydraulic oil flows directly into the lower portion of the hydraulic chamber 71 without passing through the jaunse flow path 81 and flows into the lower chamber 13 of the housing block 20. Through this process, the hydraulic oil whose pressure rises rapidly in the upper chamber 11 acts on the lower chamber 13 in a gentle state.

On the contrary, when the vehicle body of the tank gradually jumps upward from the bogie wheel 3 in the stationary state shown in FIG. 19, the housing block 20 rotates clockwise to the fully rebound state shown in FIG. 21. At this time, the piston 5 connected to the connecting rod 43 sucks the hydraulic oil filled in the upper chamber 11 to the left side.

In this case, the hydraulic oil filled in the lower chamber 13 follows the hydraulic oil movement reverse path in the jaun state, that is, the lower oil passage 81-2 and the longitudinal oil passage 81-3 at the lower portion of the hydraulic chamber 71. The upper flow path 81-1 is supplied to the upper chamber 11 through the upper portion of the hydraulic chamber 71.

Therefore, in this case as well, when the bogie wheel 3 returns to the stationary state from the rebound state, the hydraulic oil is reduced by the contraction suction force of the hydraulic oil adsorbed by the piston 15 inside the upper chamber 13. By returning to the lower chamber 13 through) it is possible to return to the original resilient suspension device (1).

However, even in this case, when the vehicle body rises rapidly from the bogie 3 and becomes a sharp rebound state, the pressure of the hydraulic oil exiting the housing block 20 also rises to the lower flow passage 83-2 of the rebound flow passage 83. High pressure is applied. Accordingly, while the relief valve 77 compresses the spring 97, the relief valve 77 is pushed to the rear of the valve chamber 95 along the guide surface of the guide plug 96, and the introduced hydraulic oil passes through the longitudinal flow path 83-3 and the upper portion. It reaches the upper part of the hydraulic chamber 71 via the flow path 83-1. After that, the hydraulic oil is returned to the upper chamber 15 through the hydraulic oil hole 88, and thus the suspension device 1 is slowly returned to a stationary state without a shock due to a sudden pressure increase through the pressure reducing action of the relief valve 77. You can come.

In this way, it can be seen that the suspension and rebound movement of the suspension device 1 according to the present invention is performed. Next, the operation of the suspension device 100 according to the second embodiment will be described.

This suspending device 100 is shown in FIG. 17 and has the same operating relationship with the suspending device 1 according to the first embodiment. However, the nitrogen chamber 114 is additionally installed at the lower portion of the suspension chamber 113 serving as the lower chamber 13 of the suspension device 1 so that a sufficient amount of nitrogen gas is provided in the suspension chamber 113 through the communication passage 140. Since it is supplied to the nitrogen filling capacity in the chamber 113 is increased to increase the load applied to the housing block 120, that is, the load of the tank vehicle body in the case of rebound or rebound.

Next, the operation of the third embodiment of the suspension device 200 according to the present invention will be described.

As shown in FIG. 18, the hydraulic fluid flow chamber 270 has an upper chamber 11 and 111 and a lower end instead of the damper 70 of the suspension device 1,100 according to the first or second embodiment. Or bolts coupled to the bolt holes 275 penetrating through the side surfaces of the housing block 20 so as to communicate with the stopping chambers 13 and 113. Since the hydraulic oil flow chamber 270 does not have a cushioning means such as a resonance valve 75 using the spring force of the spring 84 or a relief valve 77 using the spring force of the spring 97, the hydraulic fluid flow chamber 270 is abruptly as sharp as the damper 70. It does not have a function to alleviate the pressure rise, and it is merely a function of the nitrogen gas generated in the upper and lower portions of the housing block 20 or the stopping chamber by the upper and lower flow passages 272 and 274 opened up and down the hydraulic chamber 271. It only serves to transfer pressure to other chambers.

Therefore, when the suspension device 200 returns to the stopped state from the fully-unounced state or the completely rebounded state, the housing blocks 20 and 120 may also be elastically returned to their original positions by the original recovery force of nitrogen gas that has been compressed or expanded therein. Will be.
