DRIVE UNIT OF CONSTRUCTION MACHINE
PROBLEM TO BE SOLVED: To provide a drive unit of a construction machine which can properly control a distribution flow rate to each hydraulic actuator, and can improve operability performed by an operator.SOLUTION: In a flow rate distribution part 32 for calculating a distribution flow rate of pressure oil which is supplied to a plurality of hydraulic actuators on the basis of requirement flow rates of the plurality of hydraulic actuators 4 to 7, a distribution region 53 for calculating a range of the distribution flow rate of pressure oil which is actually supplied to at least two hydraulic actuators is set in a distributable region 52 which is set in order to calculate a range of a distributable flow rate being a flow rate of pressure oil which can be supplied to at least two hydraulic actuators from a plurality of pump devices with respect to at least two hydraulic actuators which are driven by a complex operation out of the plurality of hydraulic actuators, and the distribution flow rate is calculated so that the distribution flow rate is included in the distribution region, and a ratio of the distribution flow rate between the plurality of hydraulic actuators becomes equal to a ratio of the requirement flow rate.SELECTED DRAWING: Figure 3
【課題】各油圧アクチュエータに対する配分流量を適切に制御することができ、オペレータによる操作性を向上することができる建設機械の駆動装置を提供すること。【解決手段】複数の油圧アクチュエータ４〜７の要求流量に基づいて複数の油圧アクチュエータに供給される圧油の配分流量を演算する流量配分部３２において、複数の油圧アクチュエータのうち複合操作で駆動される少なくとも２つの油圧アクチュエータについて、複数のポンプ装置から少なくとも２つの油圧アクチュエータに供給可能な圧油の流量である配分可能流量の範囲を演算する為に設定した配分可能領域５２内に、少なくとも２つの油圧アクチュエータに実際に供給される圧油の配分流量の範囲を演算するための配分領域５３を設定し、配分流量が配分領域に含まれ、かつ、複数の油圧アクチュエータ間の配分流量の比率が要求流量の比率と等しくなるように配分流量を演算する。【選択図】 図３
