    • 【課題】安価で配管の取り回しを簡素化できるサスペンション装置を提供する。 【解決手段】本発明のサスペンション装置Sは、ポンプ4に接続される供給路5と、リザーバRに接続される排出路6と、ダンパDの伸側室R1に接続される伸側通路7と、ダンパDの圧側室R2に接続される圧側通路8との間に、非通電時に伸側通路7、圧側通路8、供給路5および排出路6を互いに連通するフェールポジションFを採る4ポート4位置の差圧制御弁9を設けた。そのため、本発明のサスペンション装置Sでは、一つの差圧制御弁9のみで、ダンパDをアクティブサスペンションとしても、セミアクティブサスペンションとしても機能させられ、フェールセーフ動作も可能である。 【選択図】図1

    • PROBLEM TO BE SOLVED: To provide a working vehicle suspension structure for allowing easy work for a fork by correcting the attitude of a vehicle body to set it into a predetermined attitude when a vehicle speed is low during travel.
      SOLUTION: The working vehicle suspension structure includes a hydraulic cylinder 7 for the suspension of a front wheel 1, a vehicle speed sensor Q, a check valve 13 for checking the operation of the hydraulic cylinder 7, and a hydraulic pump 30 for forcing the telescopic operation of the hydraulic cylinder in the checked condition. When the vehicle speed is changed over to be low, the check valve 13 is operated to be closed and the telescopic operation of the hydraulic cylinder 7 is forced to restore a suspension mechanism into a reference telescopic condition corresponding to the ground parallel attitude of the vehicle body.

    • PROBLEM TO BE SOLVED: To transport a cargo stabilized by automatically selecting a four-point supporting mode or a three-point supporting mode of a cargo platform.
      SOLUTION: A conveying truck apparatus includes the four-point supporting mode for supporting the cargo (W) with four support blocks (4A to 4D) having wheel devices (R1 to R4, L1 to L4) equipped with suspension cylinders and the three-point supporting mode for supporting the cargo (W) with an integrated support block integrating right and left support blocks (4A, 4B) (4C, 4D) at one side in the fore and aft direction and the right and left support blocks at the other side in the fore and aft direction, wherein a control unit selects the four-point supporting mode when a vehicle is loaded with the cargo, travelling at a high speed, and also turning, and selects the three-point supporting mode when the vehicle is emptied of the cargo, travelling at a low speed including stop, or travelling substantially straight.
