OBSTACLE DETECTION DEVICE OF CONSTRUCTION VEHICLE
To provide an obstacle detection device of a construction vehicle which can generate brake force required as emergency braking.SOLUTION: In an obstacle detection device of a construction vehicle, a brake mechanism 6 includes: a first closed circuit U1 of hydraulic pressure in which a traveling pump P provided with a swash plate S and driven by an engine and a traveling motor M for traveling the construction vehicle are connected in series; a second closed circuit U2 of hydraulic pressure which is constituted of a first oil passage T1 communicated with one side Sa of the traveling pump P and a second oil passage T2 communicated with the other side Sb and operates the swash plate S; and a neutral valve V1 which is provided in the second closed circuit U2 and is arranged in parallel with the traveling pump P. When emergency braking is operated, at least one of pressurizing restoring force for pressurizing a low pressure side of the inclined swash plate S and returning the swash plate S to neutral and decompression restoring force for decompressing the high pressure side of the swash plate S and returning the swash plate S to neutral is generated.SELECTED DRAWING: Figure 3
【課題】緊急ブレーキとして必要な制動力を発生させることができる建設車両の障害物検知装置を提供する。【解決手段】建設車両の障害物検知装置であって、ブレーキ機構６は、斜板Ｓを備えエンジンにより駆動する走行用ポンプＰと建設車両を走行させる走行用モータＭとが直列に接続された油圧の第一閉回路Ｕ１と、走行用ポンプＰの一方側Ｓａに連通する第一油路Ｔ１と他方側Ｓｂに連通する第二油路Ｔ２とで構成され斜板Ｓを作動させる油圧の第二閉回路Ｕ２と、第二閉回路Ｕ２に設けられ、走行用ポンプＰと並列に配置された中立弁Ｖ１と、を有し、緊急ブレーキが作動した際に、傾斜している斜板Ｓの低圧側を加圧して斜板Ｓを中立に戻す加圧復元力及び斜板Ｓの高圧側を減圧して斜板Ｓを中立に戻す減圧復元力の少なくとも一方を発生させることを特徴とする。【選択図】図３
