DIFFERENTIAL RESTRICTION DEVICE FOR WHEEL LOADER
PROBLEM TO BE SOLVED: To provide a differential restriction device for a wheel loader having an automatic diff-lock control function for slip prevention in each of a travel operation and a digging operation.SOLUTION: With a wheel loader 1 of the present invention, a torque value of each of left and right axle shafts 31a and 31b included in an axle device 12 is measured by a torque measuring device. An axle control device 50 performs variable control of amount of differential restriction (lock rate) of a differential restriction mechanism 40 so that wheels attached to the axle shafts 31a and 31b which have a smaller or greater torque value do not slip and break in a travel state or digging state of the wheel loader 1.SELECTED DRAWING: Figure 6
【課題】走行・掘削いずれの作業においてもスリップ防止のための自動デフロック制御機能を有するホイールローダの差動制御装置を提供する。【解決手段】本発明のホイールローダ１では、アクスル装置１２に備えられる左右のアクスルシャフト３１ａ，３１ｂのトルク値をトルク測定装置で測定し、ホイールローダ１の走行状態または掘削状態において、トルク値が小さい方または大きい方のアクスルシャフト３１ａ，３１ｂに取り付けられた車輪がスリップしたり破損しないように、アクスル制御装置５０が差動制限機構４０の差動制限量（ロック率）を可変制御するようにした。【選択図】図６
