Abstract:
Provided is a wheel loader capable of exhibiting sufficient excavation performance while suppressing slip during excavation. A control device provided on a wheel loader according to the present invention is configured to determine a reduction value (Δf′) of traveling drive force based on first vehicle body acceleration (av1) of a vehicle body calculated from acceleration detected by an acceleration sensor, second vehicle body acceleration (av2) of the vehicle body calculated from rotational speed of wheels detected by a rotational speed sensor, and thrust (ph) of a hydraulic cylinder detected by a thrust sensor, and reduce the traveling drive force based on the reduction value and output the reduced traveling drive force.
