HYDRAULIC CIRCUIT FOR TRAVELING OF COMPACTION MACHINE

Japanese Patent JP2016056509

A

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
