The left adjustment space 13 communicates with the left connection port 11 and is filled with oil. Further, since the left adjustment space 13 and the left accommodation space 311 do not communicate with each other independently, the oil in the left adjustment space 13 and the oil in the left accommodation space 311 do not circulate. A left spring (not shown) is fitted on the left suspension 3. The left spring has one end fixed to the lower portion of the left cylinder 31 and the other end fixed to the left telescopic rod 32. The structure and operation method of the right suspension 4 are the same as those of general suspension equipment. The right suspension 4 has a right cylinder 41 and a right telescopic rod 42.

Since both sides of the control valve 5 are connected to the left connection port 11 and the right connection port 21 via the connection pipe 52, the control valve 5, the plurality of connection pipes 52, the left adjustment space 13 and the right adjustment space 23 are mutually connected. Filled with oil in communication. The control valve 5 adjusts the flow of oil by a variable communication port 51 provided therein.

図1〜図3を参照する。図1〜図3に示すように、車両が真っ直ぐ前進する際、制御バルブ5の可変式連通口51が閉じられてオイルの流動が止められると、制御バルブ5、接続管52、左調整空間13及び右調整空間23がオイルにより満たされるため、左調整空間13及び右調整空間23の高さが、オイルの支持により同じに維持され、車両が横方向で支えられて直立し、安定的に真っ直ぐ前進することができる。   Please refer to FIG. As shown in FIGS. 1 to 3, when the vehicle advances straight, when the variable communication port 51 of the control valve 5 is closed and the flow of oil is stopped, the control valve 5, the connecting pipe 52, and the left adjustment space 13. Since the right adjustment space 23 is filled with oil, the heights of the left adjustment space 13 and the right adjustment space 23 are kept the same by the support of the oil, and the vehicle is supported in the lateral direction to stand upright and stably straight. You can move forward.

車両が右に旋回する際、制御バルブ5の可変式連通口51が開かれると、外方への遠心力により車両の右旋回に悪影響が及びことを防ぐことができる。即ち、車両が右方向へ傾いて重心が右方向へ傾き、右外筒体2が右サスペンション4を押下すると、制御バルブ5の可変式連通口51が既に開いているため、右調整空間23内のオイルの一部が右サスペンション4の右筒体41により押し上げられ、オイルの一部が右接続口21と、右側の接続管52と、制御バルブ5の可変式連通口51と、左側の接続管52と、左接続口11とを介して左調整空間13に流入し、右調整空間23の高さが左調整空間13より低くなるため車両が右方向へ傾き、車両が右へ旋回する際に転倒することを防ぐことができる。また、本発明の一実施形態に係る車輪の懸垂機構は、車両が右へ旋回する際、横方向の支持力と、2つの前輪と路面との接触により起きる摩擦力とにより、車両が右へ旋回する際に転倒することを防ぐことができる。また、本実施形態の車輪の懸垂機構は、制御バルブ5の可変式連通口51により車両が右に傾く速度を制御することができる。制御バルブ5の可変式連通口51が大きいほど、オイルの流動速度は速く、車両が右へ傾く速度が速くなる。また、制御バルブ5の可変式連通口51が小さいほど、オイルの流動速度が遅くなり、車両が右へ傾く速度も遅くなる。   If the variable communication port 51 of the control valve 5 is opened when the vehicle turns to the right, it is possible to prevent adverse effects on the right turn of the vehicle due to outward centrifugal force. That is, when the vehicle tilts to the right, the center of gravity tilts to the right, and the right outer cylinder 2 depresses the right suspension 4, the variable communication port 51 of the control valve 5 is already open. Part of the oil is pushed up by the right cylinder 41 of the right suspension 4, and part of the oil is connected to the right connection port 21, the right connection pipe 52, the variable communication port 51 of the control valve 5, and the left connection. When flowing into the left adjustment space 13 via the pipe 52 and the left connection port 11 and the height of the right adjustment space 23 is lower than that of the left adjustment space 13, the vehicle tilts to the right and the vehicle turns to the right. Can be prevented from falling over. Further, the wheel suspension mechanism according to the embodiment of the present invention is configured such that when the vehicle turns to the right, the vehicle is turned to the right by the lateral support force and the frictional force generated by the contact between the two front wheels and the road surface. It is possible to prevent the vehicle from falling over when turning. Further, the wheel suspension mechanism of the present embodiment can control the speed at which the vehicle tilts to the right by the variable communication port 51 of the control valve 5. The larger the variable communication port 51 of the control valve 5, the faster the oil flow speed and the faster the vehicle tilts to the right. Further, the smaller the variable communication port 51 of the control valve 5, the slower the oil flow speed, and the slower the vehicle tilts to the right.

車両が左へ旋回する際、制御バルブ5の可変式連通口51が開かれると、外方への遠心力により車両の左旋回に悪影響が及びことを防ぐことができる。即ち、車両が右方向へ傾いて重心が左方向へ傾き、左外筒体1が左サスペンション3を押下すると、制御バルブ5の可変式連通口51が既に開いているため、左調整空間13内のオイルの一部が左サスペンション3の左筒体31により押し上げられ、オイルの一部が左接続口11と、左側の接続管52と、制御バルブ5の可変式連通口51と、右側の接続管52と、右接続口21とを介して右調整空間23に流入し、左調整空間13の高さが右調整空間23より低くなるため車両が左方向へ傾き、車両が左へ旋回する際に転倒することを防ぐことができる。また、本発明の一実施形態に係る車輪の懸垂機構は、車両が左へ旋回する際、横方向の支持力と、2つの前輪と路面との接触により起きる摩擦力とにより、車両が左へ旋回する際に転倒することを防ぐことができる。また、本実施形態の車輪の懸垂機構は、制御バルブ5の可変式連通口51により車両が左に傾く速度を制御することができる。制御バルブ5の可変式連通口51が大きいほど、オイルの流動速度は速く、車両が左へ傾く速度が速くなる。また、制御バルブ5の可変式連通口51が小さいほど、オイルの流動速度が遅くなり、車両が左へ傾く速度も遅くなる。   If the variable communication port 51 of the control valve 5 is opened when the vehicle turns to the left, it is possible to prevent adverse effects on the left turn of the vehicle due to the outward centrifugal force. That is, when the vehicle tilts to the right, the center of gravity tilts to the left, and the left outer cylinder 1 depresses the left suspension 3, the variable communication port 51 of the control valve 5 is already open. Part of the oil is pushed up by the left cylinder 31 of the left suspension 3, and part of the oil is left connection port 11, the left connection pipe 52, the variable communication port 51 of the control valve 5, and the right connection. When flowing into the right adjustment space 23 through the pipe 52 and the right connection port 21 and the height of the left adjustment space 13 is lower than that of the right adjustment space 23, the vehicle tilts to the left and the vehicle turns to the left. Can be prevented from falling over. In addition, the wheel suspension mechanism according to the embodiment of the present invention is configured such that when the vehicle turns to the left, the vehicle is turned to the left by the lateral support force and the frictional force generated by the contact between the two front wheels and the road surface. It is possible to prevent the vehicle from falling over when turning. Further, the wheel suspension mechanism of this embodiment can control the speed at which the vehicle tilts to the left by the variable communication port 51 of the control valve 5. The larger the variable communication port 51 of the control valve 5, the faster the oil flow speed and the faster the vehicle tilts to the left. Further, the smaller the variable communication port 51 of the control valve 5, the slower the oil flow speed, and the slower the vehicle tilts to the left.

上述したように、本発明の車輪の懸垂機構は、左サスペンション3及び右サスペンション4により、車両はサスペンション機能を得ることができる上、路面が傾いている場合でも、制御バルブ5、左調整空間13及び右調整空間23により車両が転倒することを防ぐことができる。   As described above, according to the wheel suspension mechanism of the present invention, the vehicle can obtain a suspension function by the left suspension 3 and the right suspension 4, and the control valve 5 and the left adjustment space 13 can be used even when the road surface is inclined. The right adjustment space 23 can prevent the vehicle from overturning.
