To increase reliability while keeping a height of a vehicle body low in an unmanned transport vehicle which can detect a load of the vehicle body.SOLUTION: An unmanned vehicle 1 comprises: an arm member 4A which supports an axle of a wheel 3A; an impact absorption part 5A which connects the arm member 4A and a vehicle body 2 to each other; an angle detection part 6A which detects an angle of the arm member 4A with respect to a gravity direction g; and a control part 10 which receives an angle signal 6a output from the angle detection part 6A. The arm member 4A is configured so that an angle to the gravity direction g changes according to a load of the vehicle body 2, and the control part 10 calculates the load of the vehicle body 2 on the basis of the angle signal 6a. In summary, since the load of the vehicle 2 is calculated by the angle of the arm member 4A, a height of the vehicle 2 is not increased even when adding the angle detection part 6A. Further, since the load of the vehicle body 2 is not applied to the angle detection part 6A, reliability is also increased.SELECTED DRAWING: Figure 2
【課題】車体の荷重を検出可能な無人搬送車において、車体の高さを低く保ちつつ信頼性を高める。【解決手段】無人搬送車1は、車輪3Aの車軸を支持するアーム部材4Aと、アーム部材4Aと車体2を接続する衝撃吸収部5Aと、重力方向gに対するアーム部材4Aの角度を検出する角度検出部6Aと、角度検出部6Aから出力される角度信号6aを受ける制御部10とを備える。アーム部材4Aは、車体2の荷重に応じて重力方向gに対する角度が変化するよう構成され、制御部10は角度信号6aに基づいて車体2の荷重を算出する。このように、アーム部材4Aの角度によって車体2の荷重を算出していることから、角度検出部6Aを付加しても車体2の高さが高くなることがない。しかも、角度検出部6Aに車体2の荷重が加わらないことから信頼性も高められる。【選択図】図2
