Problems solved by technology
[0002] Compared with the traditional mechanical system, the hydraulic system can realize a wide range of stepless speed regulation, and it can realize seamless transmission and smooth movement during transmission. Therefore, the hydraulic system is often selected to replace the mechanical system for drive and control, and the hydraulic travel drive The hydraulic system is the most commonly used hydraulic system, but the traditional hydraulic travel drive system, due to the use of conventional hydraulic pumps and conventional hydraulic motors, is prone to wear and tear under high-speed and high-pressure conditions, and it takes a long time It will damage the hydraulic system, and even make the hydraulic system scrapped. Its work reliability is poor and its system versatility and practicability are too low.
