摘要

"System to control the differential lock for a vehicle hired in articulated work vehicle hired to work and to perform an operation of work".A work vehicle with four wheel drive is provided with a front axle and a front differential and a rear axle having a rear differential.Both elements are provided with locking differential that are operated hydraulically coupled to the control valve solenoid.The solenoid control valves are coupled to the microprocessor.The microprocessor has a manual mode in which the differential locks are controlled by a foot pedal in the cockpit of the operator and an automatic mode in which the microprocessor controls the locking difDeliver in response to signals of speed of the axles and the transmission.The microprocessor calculates a predicted based on shaft speed signal output speed of the transmission received by a sensor of speed of transmission.The microprocessor then compares this signal to the speed signs of real axis received from the speed sensors and activates the respective axle solenoid valve if the difference is bigger thanA programmed amount. A sensor of angle of articulation sends a signal of angle of articulation to the microprocessor.If the link is greater than a programmed amount of the solenoid locks are released.
