The operation of the amphibious boat shown in FIG. 1 will be described. First, the operation when the amphibious boat is moved forward by rowing an oar on land will be described. When advancing the boat by rowing the oar, the oar is rowed in front with the tip of the oar submerged in the water.
Paddle in the direction of the thick black arrow, with the height raised above a predetermined value. The drive ring 5, and hence the clutch LM guide 7, moves in the direction of the thick black arrow along the driving LM guide 8 by the movement of the wheel 4 in the direction of the thick black arrow. When the clutch LM guide 7 moves along the driving LM guide 8 in the direction of the thick black arrow, the first driving chain 10 driven by the clutch LM guide 7 moves in the direction of the thick black arrow. As a result, the first drive gear 11 and the first flywheel gear 20 rotate in the direction of the thick black arrow. When the first driving gear 11 rotates in the direction of the thick black arrow, the first driving pulley 13 also rotates in the direction of the thick black arrow. At this time, since the wheel 4 is lifted to a height higher than a predetermined value, the drive clutch 32 presses the V-belt 14 by the urging force of the spring 33. (State of FIG. 3a or FIG. 3b) Therefore, the rotational force of the first drive pulley 13 is V
It is transmitted to the second drive pulley 15 by the belt 14. Further, the rotational force of the second drive pulley-15 is the second
Drive gear 16, second drive chain 17, and third
Is transmitted to the drive wheels 2 via the drive gear 18 of the above, and the amphibious boat moves forward. As described above, the propulsive force is applied to the boat and the boat is moved forward by rowing the ore with the tip of the oar submerged in water.
By rowing the ore 4 in the state where the reel 4 is lifted, the driving force is transmitted to the driving wheels 2 of the amphibious boat, and the amphibious boat is reproduced by a forward movement on land.

On the other hand, when the ore is returned after rowing, the propulsive force is not applied to the boat because the ore is lifted above the water surface and returned. This movement is referred to as the clutch link 30, the clutch cable 31, the drive clutch 32,
It is reproduced by the transmission control means including the spring 33 and the like. The operation is the same as the operation of lifting the ore on the water surface and returning the ore, that is, the ore 4 is returned in the direction of the thick white arrow with the height lowered to a predetermined value or less. When the wheel 4 moves in the direction of the thick white arrow, the drive ring 5, and thus the clutch LM guide 7, moves in the direction of the thick white arrow along the driving LM guide 8. When the clutch LM guide 7 moves along the drive LM guide 8 in the direction of the thick white arrow, the first drive chain 10 causes the first drive gear 11 and the first flywheel gear 20. Rotates in the direction of the thick white arrow. When the first driving gear 11 rotates in the direction of the thick white arrow, the first driving pulley 13 also rotates in the direction of the thick white arrow. At this time, since the hole 4 is lowered to a height equal to or lower than a predetermined value, the clutch link 3
Due to the deformation of 0, the clutch cable 31 is pulled and the drive clutch 32 is lifted, and the slip of the V-belt 14 is increased. (State of FIG. 3c) Therefore, the rotational force of the first drive pulley 13 is the second
Is not transmitted to the driving pulley 15. As described above, the movement in which the propulsive force is not applied to the boat is reproduced when the ore is lifted above the water surface and returned.

Further, the propulsive force applied to the boat changes depending on whether the tip of the hole is shallowly submerged in water or when the hole is deeply inserted. To do. This motion is reproduced by the torque control means including the variable differential limiting device 12, the clutch link 30, the viscous cable 34, the non-linear cam 35, the transmission torque control member 36, the inner piston 37 and the like. That is, the four
The vertical movement of the drive ring 5, the clutch link 30,
The stroke amount of the inner piston 37 is converted through the viscous cable 34, the non-linear cam 35, and the transmission torque control member 36, and the variable differential limiting device 12 adjusts the stroke amount of the inner piston 37 according to the stroke amount. 1 drive gear 11
The transmission efficiency of the torque transmitted from the first drive pulley 13 to the first drive pulley 13 is changed. Inner and height of the upper and lower of the four
The relationship with the stroke amount of the piston 37 is shown in FIG. FIG. 5 shows the relationship between the stroke amount of the inner piston 37 and the transmission efficiency of the variable differential limiting device 12. When the tip of the hole is deep in the water, that is, when the height of the hole 4 is high, the non-linear cam 35 hardly rotates. (State of FIG. 3a) Therefore, since the stroke amount of the inner piston 37 is small, the transmission efficiency of the variable differential limiting device 12 is high.
When the tip of the oil is shallow in water, that is, when the height of the oil 4 is near a predetermined value, the non-linear cam 35 is used.
Rotates and the inner piston 37 is pushed in. (State of FIG. 3b) Therefore, the transmission efficiency of the variable differential limiting device 12 becomes small. The amount of rotation of the non-linear cam is large when the tip of the hole is lifted above the water surface, that is, when the hole 4 is lowered to a height equal to or lower than a predetermined value. (State of FIG. 3c) Therefore, the transmission efficiency of the variable operation limiting device 12 is small. As described above, the movement in which the propulsive force applied to the boat changes according to the depth of the tip of the hole in water is reproduced.

The movement when the boat is retracted by rowing the hole is reproduced by the same action as when the boat is moved forward by rowing the hole. When the tip of the hole is deeply immersed in the water, that is, when the height of the hole 4 is high and the paddle is rowed in the direction of the thick white arrow, the transmission efficiency of the variable differential limiting device 12 is large and the wheel 2 is driven. The driving force is transmitted and the amphibious boat retreats at high speed. When the tip of the hole is shallowly put in the water, that is, when the height of the hole 4 is near a predetermined value, the variable differential limiting device 1
The driving force is transmitted to the drive wheels 2 in a state where the transmission efficiency of 2 is small, and the amphibious boat retreats at a low speed. On the other hand, when the tip of the hole is lifted above the surface of the water, that is, when the hole 4 is lowered to a height equal to or lower than a predetermined value and returned in the direction of the thick black arrow, the clutch link 30 is deformed to drive. Since the vehicle clutch 32 is lifted, the driving force is not transmitted to the drive wheels 2.

When the left and right wheels are rowed in the direction of the thick black arrow or the thick white arrow, the driving force transmitted to the left and right driving wheels by varying the height and the rowing force of the left and right wheels. It is possible to change the advancing angle of the amphibious boat by making the difference. It is also possible to rotate the amphibious boat by rowing only one or the left and right wheels in different directions.

Further, when the height of the alley is rowed within a predetermined range, not only the transmission efficiency of the variable operation restricting device 12 changes, but also the V belt 14 as shown in FIG. 3b.
The slip also changes. Therefore, the clutch link 3
It is necessary to adjust the change characteristic of the slip of the V-belt 14 with respect to the deformation amount of 0 and the change characteristic of the transmission efficiency of the variable differential limiting device 12 with respect to the deformation amount of the clutch link 30.
Alternatively, in order to eliminate the need for such an adjustment, the drive clutch is only provided when the height of the wheel 4 is below a predetermined value, that is, when the deformation amount of the clutch link 30 is above a predetermined amount. 32 may be lifted and the drive clutch 32 may be pressed against the V-belt 14 when the deformation amount of the clutch link 30 is less than or equal to a predetermined amount. Further, in the above description, the first drive chain 10 is used.
The amphibious boat was moved on land with the flywheel 24 and the flywheel 24 being connected via the one-way clutch 23. However, when the amphibious boat is moved on land, the first flywheel is used. -The connection between the first drive chain 10 and the flywheel 24 is released by controlling the connection state between the gear 20 for the second flywheel and the gear for the second flywheel or the operating state of the one-way clutch 23. You may do it.

Next, the operation when the amphibious boat is used as an indoor training machine (ergometer) will be described with reference to FIG. In FIG. 2, the same reference numerals as those in FIG. 1 indicate the equivalents. Reference numeral 40 is a training lever that is operated when the amphibious boat is used as an indoor training machine. Reference numeral 41 is a training cable for actuating the drive brake 42 to apply a brake to the second drive gear 16 when the training lever 40 is operated. 43 is a lever for training

The transmission of the driving force to the driving wheels 2 is forcibly blocked. Further, the breaking force of the flywheel brake 45 is adjusted by the flywheel cable 44 according to the operation amount of the training lever 40. Incidentally, a lever for operating the training cable 41 and the training wire 43 and a lever for operating the flywheel cable 44 may be separately provided. Further, when the amphibious boat is used as an indoor training machine, the operation of the variable operation limiting device 12 may be stopped.

Furthermore, when the amphibious boat is operated as a boat on the water, the hole 4 and the transmission means may be left connected or the connection between the oil 4 and the transmission means may be released. You may do it. There are various methods for releasing the connection between the oil 4 and the transmission means.
