ROLLING MACHINE
PROBLEM TO BE SOLVED: To provide a rolling machine that eliminates the need to extend a hydraulic hose from a front vehicle body to a rear vehicle body so as to apply pilot pressure to switching means of switching output of a hydraulic motor for travel for a rear rolling wheel, and thereby can eliminate problems associated with a space at a periphery of an articulate mechanism resulting from addition of the hydraulic hose and anxiety about breaking of the hydraulic hose.SOLUTION: Hydraulic oil from a steering charge hydraulic pump 20 mounted on a front vehicle body 3 is supplied to a parking brake 41r for a rear rolling wheel 4 provided to a rear vehicle body 5 through a hydraulic hose (oil passage 43), and a vehicle 1 is stopped and held through the operation thereof. Hydraulic oil is fed from the oil passage 43 at the rear vehicle body 5 and supplied to a high/low solenoid valve 47r through the oil passage 49, and pilot pressure is supplied to a high/low selector valve 40 according to opening and closing of the high/low solenoid valve 47r to switch the output of the hydraulic motor 30 for rear part travel between two high and low stages.SELECTED DRAWING: Figure 2
【課題】後部転圧輪の走行用油圧モータの出力を切り換える切換手段にパイロット圧を供給すべく前部車体から後部車体側に油圧ホースを延設する必要がなく、これにより油圧ホースの追加に起因するアーティキュレート機構の周辺のスペースの問題、及び油圧ホースの破損の懸念を解消できる転圧機械を提供する。【解決手段】前部車体３に搭載されたステアリング・チャージ用油圧ポンプ２０からの作動油を油圧ホース（油路４３）を経て後部車体５に設けられた後部転圧輪４用の駐車ブレーキ４１ｒに供給し、その作動により車両１を停止保持可能とする。後部車体５において油路４３から作動油を採り出して油路４９を経て高低電磁弁４７ｒに供給し、高低電磁弁４７ｒの開閉に応じて高低切換弁４０にパイロット圧を供給して後部走行用油圧モータ３０の出力を高低２段に切り換える。【選択図】図２
