走行装置。[Claims for Utility Model Registration] 1. An oil cylinder 10 for pressing the crawler tension ring 2 in the tensioning direction, and an oil chamber 13 communicated with this oil cylinder 10 via an oil passage 14 are provided, and this oil chamber a sliding piston 15 for discharging the internal oil 19 of 13 toward the oil cylinder side, and a crawler tension spring 16 for biasing the sliding piston 15 in the discharging direction.
is installed in the oil chamber 13, and the closed state disables oil flow from the oil cylinder side to the oil chamber side, the oil flow from the oil cylinder side to the oil side, and the oil flow from the oil chamber side. The crawler type traveling device includes an on-off valve 17 in the oil passage 14 that can be switched to an open state to allow oil to flow toward the oil cylinder. 2. The crawler tension spring 16 that slides and biases the crawler tension ring 2 in the tension direction and the sliding member 23 that transmits the biasing force of the crawler tension spring 16 to the crawler tension ring 2 are placed in the spring chamber 2.
An oil pump 26 is installed inside the spring chamber 22 and supplies oil to the spring chamber 22, and the spring chamber 22 is in a closed state in which the oil inside the spring chamber 22 is not allowed to flow out, and the sliding member is slid on the relaxed side and on the tension side. The spring chamber 22 is in an open state allowing movement.
A crawler type traveling device equipped with an opening/closing means 25 for switching.
