Principle of gearbox of Gong Shan 660d loader

Speed change and torque are realized by hydraulic transmission and gear combination. According to the query of China Construction Machinery Business Network, the SEM660D loader of Gong Shan Machinery adopts the unique loader gearbox in the industry, and its design life is longer than that of the planetary gearbox 1 times, which is fully upgraded. Friction plates, bearings and oil seals are made of world-class brand parts, which are more reliable and durable, and are suitable for heavy-duty working conditions such as mines, ports and cement. Among them, the working principle of loader gearbox is mainly composed of gears and shafts, which produce speed change and torque through different gear combinations. Automatic gearbox AT is composed of hydraulic torque converter, planetary gear and hydraulic control system, which realizes variable speed and torque through hydraulic transmission and gear combination.
