HYDRAULIC CIRCUIT FOR TRAVELING OF COMPACTION MACHINE
PROBLEM TO BE SOLVED: To provide a hydraulic circuit for traveling of a compaction machine that suppresses rise in a temperature of hydraulic fluid, by reducing a pressure loss while driving a hydraulic motor for traveling compared to conventional technologies.SOLUTION: A hydraulic circuit includes: a hydraulic pump 1; a first supply line 4 having one end connected to the hydraulic pump 1; a diversion/collection valve 5 connected to the other end of the first supply line 4, for diverting hydraulic fluid from the first supply line 4 to a second supply line 6 and a third supply line 7, or collecting the hydraulic fluid from the second supply line 6 and the third supply line 7 into the first supply line 4; a first hydraulic motor 2 for traveling connected to the second supply line 6; a second hydraulic motor 3 for traveling connected to the third supply line 7; a communication passage 10 for communicating the second supply line 6 with the third supply line 7; and a first electromagnetic valve 11 interposed on the communication passage 10 for adjusting the hydraulic fluid flowing through the communication passage 10. The first electromagnetic valve 11 is operated in linkage with a second electromagnetic valve 9.SELECTED DRAWING: Figure 1
【課題】従来に比して走行用油圧モータ駆動時の圧力損失を低減して作動油の温度上昇を抑制する。【解決手段】油圧回路は、油圧ポンプ１と、一端部を油圧ポンプ１に接続する第１供給管路４と、第１供給管路４の他端部に接続し、該第１供給管路４からの作動油を第２供給管路６及び第３供給管路７に分流、若しくは第２供給管路６及び第３供給管路７からの作動油を第１供給管路４に集流する分流・集流弁５と、第２供給管路６に接続する第１走行用油圧モータ２と、第３供給管路７に接続する第２走行用油圧モータ３と、第２供給管路６と第３供給管路７とを連通する連通路１０と、連通路１０に介挿され該連通路１０を流通する作動油を調整する第１電磁弁１１と、を備える。そして第１電磁弁１１と第２電磁弁９は、連動して動作する。【選択図】 図１
