The basic concept of hydraulic transmission and the development trend of cycloid hydraulic motor

Description of content: Walking drive system is an important part of construction machinery. The design and development of closed test control circuit for limit load regulation, DC power supply for automobile speed control and variable system for hydraulic rotating motor with constant power have given a general development prospect for the application of hydraulic transmission in construction machinery running system.

Walking drive system is an important part of construction machinery. Compared with the working system, the walking drive system must not only transmit a lot of power, requiring electronic devices to have too much effect and longer service life, but also hope to have high quality professional ability in variable speed, transfer box, change the rotation direction of output shaft and reverse transmission driving force and other industries. Therefore, which kind of transmission mode to use, how to better achieve a variety of construction machinery walking drive must be, has been the construction machinery industry to solve the research topic. Especially in recent years, along with the urban traffic in China, energy infrastructure projects such as public infrastructure construction progress trend, with the rapid development of engineering construction building construction design and resources development enterprise scale continuous development trend of construction machinery at the request of the market has greatly promoted in addition, more suffered more demanding hydraulic impact motor in geographical environment, The challenges posed by the more complex conditions and specifications in the work are further driving the detailed analysis of the walking drive system. This paper tries to discuss the development and periodicity of hydraulic transmission specialty in construction machinery walking drive system from the perspective of system construction and action characteristics. Construction machinery walking system is the first important use of industrial equipment transmission and hydraulic mechanical transmission (full hydraulic excavator). Nowadays, the transmission mode of four-column hydraulic press and electric power installation engineering transmission also appears in the construction machinery walking driving machine equipment, which shows that the development trend of scientific and technological innovation has a great role in promoting this field. The price of hydraulic motor is reasonable.
