The corner hydraulic transmission shaft is a special type of transmission shaft that combines the characteristics of hydraulic transmission technology and corner transmission.Its main working principle is to use a hydraulic system to transmit power, enabling the shaft to effectively transmit torque and power even at corners where there are angular changes. This type of transmission shaft usually has good flexibility and can adapt to some transmission scenarios with complex spatial layouts and angular changes (i.e., at corners). Compared with traditional mechanical transmission shafts, the corner hydraulic transmission shaft has certain advantages when dealing with complex spatial structures and angular changes, and can reduce situations such as reduced transmission efficiency or mechanical wear caused by angular issues. It may be applied in some specific mechanical equipment, engineering vehicles, or industrial installations. However, its structure is relatively complex, and there are also higher requirements for the maintenance and reliability of the hydraulic system.
