These include soft ground, wetlands, and snowy areas.
これらの地形、地物を走行踏破するとき、履帯自動車に
影響するものは車両の地上高と接地圧が最も大きい。When traveling over these terrains and features, the biggest influences on tracked vehicles are the vehicle's ground clearance and ground pressure.

、遂には推進不能に屡々陥るという問題点があった。The bottom of the vehicle comes into contact with 4 stone blocks, tree roots, protrusions on the running surface, etc., as shown in Figure 4 (a), and the vehicle is often pushed up, making it impossible to drive. earth,
In muddy areas, wetlands, etc., as shown in Figure 6 (a), as the crawler vehicle sinks, the lower abdomen of the crawler body comes into contact with these objects and presses against them, creating an enormous running resistance. The problem was that the tracks tended to float up, reducing the driving force, and often resulting in a loss of propulsion.
本発明は、上記の問題点を解決することを技術的課題と

It is characterized by being equipped with a central track with variable K track position.
なお、実施に当っては、上記中央履帯は一連又は二連装

て従来のとの種履帯自動車と同様の働きをする。(Function) Since the present invention is configured as described above, when driving on a flat ordinary road, that is, when driving on the road, the central crawler track is lifted to the retracted position where it comes into contact with the bottom surface of the vehicle body. Make it take a retracted position. As a result, the core tracked vehicle functions in the same way as a conventional type tracked vehicle only with the main tracks attached to both sides of the vehicle body.

（粘着力）が増大する。On the other hand, on a running surface where there are many obstacles when traveling off-road, the central crawler track on the bottom of the vehicle body is pushed down to bring the central crawler track into contact with the running surface. This produces the same effect as if the vehicle ground height were infinitely increased, and the ground pressure is reduced, making it easier to traverse soft roads, etc. However, the adhesion force (adhesive force) when climbing on a steep slope or traversing a slope increases.
従って、主履帯と共に中央履帯を駆動することにより、
各種の障害が克服され、踏破することが可能となる。Therefore, by driving the central crawler along with the main crawler,
Various obstacles can be overcome and overcome.

。Note that an idler wheel is required between the gears 5 and 6 to make the central crawler sprocket 12 rotate in the same direction as the main sprocket 4, but it is omitted in the drawing. In addition, the power transmission, speed increase, and intermittent transmission do not depend on gears, and the gears 5 and 6 are replaced with sprockets, and the power is transmitted through a chain.
It is also possible to provide an intermittent clutch on the drive shaft 7. In addition, the shaft 25 of the visiting wheel 26 that guides the central h1 zone 13
is connected to the piston rod of the hydraulic cylinder 24 so as to be slidable along the guide frame 27 . (Fig. 2) Next, we will mainly explain the mechanism for raising and lowering the central crawler track 13 described above, pushing down the tb, and pulling it up.
To explain with reference to the figure, one double-acting hydraulic cylinder 17 is provided at the front and the rear, each of which is operated by receiving a hydraulic pressure source from an oil cylinder which is driven by the driving force of the prime mover of the main vehicle. The central crawler frame 14 is held by two central crawler arms 20 on the left and right sides of the vehicle body 1 at support points 18 and holding points 19. The point of action 16 on the central crawler arm 20 is connected to the left and right sides by a horizontal shaft (link) 21 (FIG. 3). A central portion 23 (FIG. 3) of the horizontal shaft 21 is connected to a piston rod of a hydraulic cylinder 17, and the other end of the hydraulic cylinder 17 is rotatably attached to the main vehicle frame 15. In addition, in the figure, 22 is a center track wheel,
28 is a guide wheel of the main crawler belt 2, and 29 is a rolling wheel of the main crawler belt 2.

れ１３゜、１４゜。Next, to explain the operation, by extending the hydraulic cylinder 17, the central crawler arm 20 is pushed down, and the central crawler frame 14 is pushed down, and the central crawler wheel 22 attached to the central crawler frame 14 is pushed down. The central crawler belt 13 is pushed down to the ground, and the central crawler belt 13° and the central crawler frame 14. Connecting portion 16. Holding point 19° arm 20. The rotation N122 is 13° and 14°, respectively.

から走行姿勢（一点鎖線〕となる。The positions are 16o, 19o, 20°, and 22o. Further, the guide wheel 26 is rotated by the contraction of the double-acting hydraulic cylinder 24.
26a position and the central crawler track device is in the retracted position (solid line)
From this point on, the vehicle enters the running position (dotted chain line).

けることも可能である。In this case, since the circumference of the central crawler belt 13 is constant, the central crawler track wheels 22 are pushed down, so that the central crawler belt 1
The double-acting hydraulic cylinder 2, whose one end is supported by the vehicle body,
4 is contracted and the other end is held by the guide wheel shaft 25.
(FIG. 3) is pulled back via the guide rail 27 provided on the main vehicle frame 15, the guide wheel 26 is thus at the position 26o, and the central crawler track 13 is adjusted to an appropriate tension. Note that the above-mentioned double-acting hydraulic cylinder 24 may not be provided in the center, but may be provided independently on the shafts of the left and right guide wheels.

〕に戻る。Next, the conversion from the traveling attitude to the retracted attitude is performed by an operation reverse to that described above. That is, by contracting the hydraulic cylinder 17 and extending the hydraulic cylinder 24, the central crawler frame 14o is pulled up to position 14, the central crawler track wheels 22° are at 22, and the central crawler 136 is at 1.
3, the guide wheel 26o becomes 26 and returns to the retracted position (solid line position).
中央履帯１３は格納姿勢においても、歯車６を摺動して
歯車５にかみ合はせ、動力を伝達することにより駆動が
可能である。Even in the retracted position, the central crawler track 13 can be driven by sliding the gear 6 to mesh with the gear 5 and transmitting power.
この実施例によれば、次のような各事項について効果を
奏する。According to this embodiment, the following effects can be achieved.
（１）車両の地上高：

性２乗心地、走行性能等が低下することは避けられない
のに対し、本実施例では、中央履帯装置を有するので、
格納姿勢では地上高はＬＯＯＩｌｌもあれば充分である
と考えられる。(1) Vehicle ground clearance: Conventional vehicles are designed to have as high a ground clearance as possible when off-road driving is taken into account. While it is inevitable that the vehicle's stability, riding comfort, running performance, etc. will deteriorate, this embodiment has a central track device, so
In the stowed position, it is considered that LOOIll is sufficient for ground clearance.
また路外走行において障害物がある場合は、第４図（ｂ

場合は、中央履帯に動力を伝達することなく、中央履帯

である。In addition, if there is an obstacle when driving off-road, please refer to Figure 4 (b).
) As shown in (c), it is possible to cross by transmitting power to the central crawler track 13. Note that if the running resistance is small, it is also possible to cross the terrain using only the propulsive force of the main crawler by idling the central crawler without transmitting power to the central crawler.
（１１）接地圧の減少：

’、 Ｑ７勾工。(11) Decrease in ground pressure: If the ground pressure is expressed by the following formula, then from Fig. 5, the ground pressure q of the conventional vehicle (Fig. Comparing the ground pressure q' of the vehicle of the example (FIG. 6(b)), approximately W: vehicle weight kgf', Q7 grade.
となり、妥地圧の減少により軟弱地、積雪地、泥渾地等
通過の踏破可能性は増大する。As a result, the possibility of traversing soft ground, snowy ground, muddy ground, etc. increases due to the decrease in ground pressure.
中央履帯装置の場合の接地面積は、中央履帯の配置、保
持、駆動装置等の関係から主履帯の接地面積の７５〜８
５％位と考えられる。The ground contact area in the case of a central crawler device is 75 to 8 times the ground contact area of the main track due to the arrangement, retention, drive device, etc. of the central track.
It is thought to be around 5%.
（ｉｉｉ）車両の沈下および走行抵抗；従来の車両では
、第６図（ａ）のように、軟弱地。(iii) Subsidence and running resistance of the vehicle; in conventional vehicles, as shown in FIG. 6(a), the ground is soft.

抵抗が増加して、走行抵抗が増大したのに対し、本実施
例の中央履帯装置付車両では、同図（ｂ）のように、車
体底部の接触部分はない。In snowy areas, muddy areas, etc., the vehicle sinks and the bottom of the vehicle body touches the ground, which increases running resistance and causes the main tracks to float up, eventually making it impossible to drive and causing the vehicle to become damaged. As the vehicle subsides, contact resistance also increases on the sides of the vehicle, the S-carriage system, and the main track side, resulting in an increase in running resistance.In contrast, in the vehicle with the central track system of this example, as shown in Figure (b). , there is no contact part on the bottom of the car body.
そして車両の沈下量は、第６図（ａＪから従来車両をり

であシ、このため車両側面、懸架装置、クローラ側面は
車両の沈下が少ないため、接触抵抗も小であり、従来車
両に比して走行抵抗が小である。The amount of subsidence of the vehicle is shown in Figure 6 (aJ for the conventional vehicle and h' for the vehicle with central track device from Figure 6(b)).
Vehicles with central JIyI band devices have low ground pressure, so h>
>h' Therefore, since the side of the vehicle, the suspension system, and the side of the crawler have little subsidence of the vehicle, the contact resistance is also small, and the running resistance is small compared to the conventional vehicle.
ａｙ＞ 耐スリップ性の向上ニ

渾地等の踏破性など機動性が増大する。ay＞ Improved slip resistance In the case of general tires for automobiles, the smaller the flatness of a flat tire compared to a regular round tire, the greater the adhesion force.
In the same way that slip resistance is improved, the vehicle with the central track device of this example has an increased ground contact area outside the central track and has a weaker adhesive force, which improves the ability to climb slopes, soft ground, snowy ground, and muddy ground. Increased maneuverability, including the ability to traverse waterways, etc.
（Ｖ）高速機動性：
最高速度は、一般の履帯車両とほぼ同等の機動性を保持
しうる。(V) High-speed maneuverability: The maximum speed can maintain maneuverability almost equivalent to that of a general tracked vehicle.
中央履帯を引き揚げて、格納姿勢とすれば、一般の履帯
自動車と変シはない。但し、中央履帯装置関係の重債分
だけ車両重量は増加して走行抵抗が増大することは赴け
られない。If you pull up the central track and put it in the retracted position, there is no difference from a regular tracked car. However, it cannot be avoided that the weight of the vehicle increases due to the burden associated with the central track device, which increases running resistance.

する。(Vl) The vehicle body posture is adjusted as shown in Fig. 7 (b) by applying the super tsutsumi no crab central crawler lifting device.
As shown in the figure, the rear lifting hydraulic cylinder 17 is contracted and the front hydraulic cylinder 17 is extended to its maximum extension to bring the vehicle into an upward position, converting the normal position (a) to the open position (b). The levee capacity is from H in the same figure (a) to J in the same figure (1
)), the height of the embankment D (D > H), which cannot be crossed in the normal posture, becomes D <H' in the same figure (b).
Therefore, by applying the central 1iνshu device, the supercapacity can be increased.

In contrast to the situation where the main crawler track 2 is forced to tilt as shown in a), by pushing the entire center track 13 down to the maximum stroke extension of the hydraulic cylinder,
In addition to protecting the main crawler track 2 as in 1)), no strain is placed on the main track wheel arm, etc., and it becomes easier to traverse the V-junction.
