D355 / D155 Torque Converter Bulldozer Hydraulic Torque Converter Parts
The D355 / D155 torque converter is a core component in the hydraulic transmission system of heavy-duty bulldozers. Its main function is to convert the engine's output power into hydraulic energy and transmit it to the transmission and track system, enabling smooth starting and traction output. This device typically integrates sub-components such as the pump impeller, turbine, and stator, and automatically matches the torque conversion ratio based on load and speed. The product features a high-strength steel structure and precision dynamic balancing design, ensuring continuous and stable operation in high-temperature, high-load environments.
