Abstract
Provided is a control device for a wheel loader that is capable of improving the productivity of excavation work by reducing the work time required for the excavation work. A control device 120 is a control device for a wheel loader 1 that excavates a target by moving a vehicle body 2 forward with rotation of wheels 5f, 5r to plunge a bucket 3 into the target. The control device 120 moves the vehicle body 2 forward with the bucket 3 plunged into the target, and brakes the wheels 5f, 5r when a rotational speed of the wheels 5f, 5r exceeds a predetermined threshold BS.
Claims9
A control device for a wheel loader that excavates a target by moving a vehicle body forward with rotation of wheels to plunge a bucket into the target, wherein
- the control device moves the vehicle body forward with the bucket plunged into the target, and brakes the wheels when a rotational speed of the wheels exceeds a predetermined threshold, such that a difference between a rotating amount of the wheels calculated from the rotational speed of the wheels and a moving amount of the wheels relative to a ground surface calculated based on a speed of the vehicle body before the bucket is plunged into the target and a deceleration of the vehicle body due to a reaction force from the target is within a range of a limit value in which the wheels do not slip.
