Gearbox The power shift transmission is operated by a shift control valve and can be shifted directly without stopping. Used in conjunction with a torque converter can greatly reduce the driver's labor intensity. The transmission consists mainly of four planetary rows and a rotary lock clutch. Multi-plate clutch, hydraulic pressure combined with forced lubrication, divided into three forward and three reverse. |

Hydraulic torque converter The torque converter is a technology introduced from Komatsu, Japan, using military technology. A new generation of products that have been innovatively developed in terms of materials, processes and structures. The utility model has the advantages of simple structure, convenient maintenance, low noise, high reliability, stepless speed regulation, and easy matching with the host. The bulldozer is provided with excellent traction performance to ensure a smooth transmission of the machine. |
