AI Technical Summary
Technical Problem
In existing technologies, the tractor's travel motor and PTO motor are designed separately, resulting in a non-compact structure, higher cost, and difficulty in meeting the high torque requirements and energy-saving and emission-reduction requirements of agricultural machinery.
Method used
It adopts a highly integrated design, connecting the walking motor and the PTO motor in series with connecting screws. The design of the central shaft and tube body realizes power transmission, and the isolation distance is controlled at 2-3 mm to ensure independent operation.
Benefits of technology
This design achieves a compact motor structure, reduces costs, and meets the demands for high horsepower and high torque, thereby improving the practicality of the tractor.
