To provide an abnormality detection device capable of detecting an abnormality of lubrication circuits without increasing the number of temperature sensors in a lubrication device having the two lubrication circuits.SOLUTION: When a first oil pump P1 is driven and a second oil pump P2 is stopped, only a first lubrication circuit 20 is operated. When the second oil pump P2 is driven and the first oil pump P1 is stopped, only a second lubrication circuit 24 is operated. Therefore, in a traveling state where only one of the oil pumps is driven, by detecting a lubrication oil temperature Toil of lubrication oil by using an oil temperature sensor 48, an abnormality of each of the first lubrication circuit 20 and the second lubrication circuit 24 can be detected based on the lubrication oil temperature Toil.SELECTED DRAWING: Figure 3
【課題】2つの潤滑回路を有する潤滑装置において、温度センサの数を増やすことなくこれら潤滑回路の異常を検出できる異常検出装置を提供する。【解決手段】第1オイルポンプP1が駆動する一方、第2オイルポンプP2が停止すると、第1潤滑回路20のみ作動し、第2オイルポンプP2が駆動する一方、第1オイルポンプP1が停止すると、第2潤滑回路24のみ作動する。従って、一方のオイルポンプのみが駆動している走行状態で油温センサ48によって潤滑油の潤滑油温Toilを検出することで、その潤滑油温Toilに基づいて第1潤滑回路20および第2潤滑回路24のそれぞれの異常を検出することができる。【選択図】図3
