FIELD: agriculture.SUBSTANCE: group of inventions relates to a transmission device and a method of actuation of agricultural operating mechanism and a combination of the vehicle and the claimed transmission device. The transmission device comprises a motor, a transmission of operating mechanism with a protector sleeve, a control device. The control unit is connected to a sensor to determine the operating torque of the power take-off shaft. The motor can communicate with the power take-off shaft output through the split sleeve. The method consists in that the motor and transmission are actuated. Breaking of transmission is carried out when the shutdown moment is exceeded the operating torque of the power take-off shaft is determined. The sleeve of the power take-off shaft is opened when the operating torque reaches a threshold value or exceeds it. The control device applies during normal operation the first threshold value. The first threshold value corresponds to the operating torque which is less than the shutdown moment of the protector sleeve. The control device after exceeding the first threshold value causes the actuator to close the sleeve of the power take-off shaft. The control device at the closed sleeve allows greater operating torque at the output of the power take-off shaft than the shutdown moment of the protector sleeve. The claimed device and the vehicle is a combination of these devices.EFFECT: prevention of overdrive of operating mechanisms.13 cl, 3 dwg |
