Abstract:
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
