Study on the Control of Torque Distribution of 4WD Corn Harvester Operation Drive

In response to the poor adaptability of existing harvesters complex operating conditions in field, this study took a three-row four-wheel-drive (4WD) corn harvester as research object, designed traveling transmission system layout, proposed control strategy driving torque distribution, simulated, and analyzed each four states drive wheels slippage. The results showed that under slipping condition, after applying control, adjustment time was 43.3% shorter than without case single wheel slipping, 11.1% two on same axle, 41.4% different axles, 36.6% three slipping. application distribution could significantly improve traction passing ability during operation, well made travel more smoothly, thus improving harvest quality. can be applied not only harvester, but also other types harvesters, self-propelled agricultural machinery enhance their adaptability, operation It has significant reference value for development walking machinery.
