711-67-03010 TORQUE CONVERTER A

Bulldozer hydraulic torque converter is a hydraulic transmission device that uses liquid kinetic energy to transmit and change torque. It mainly consists of three basic components: pump impeller, turbine, and guide wheel, as well as the torque converter housing. Here is a detailed introduction:Working principle: The engine drives the pump wheel to rotate, which accelerates and throws the liquid towards the turbine. The high-speed flowing liquid impacts the turbine blades, pushing the turbine to rotate and transmitting torque to the output shaft. The guide wheel is located between the pump wheel and the turbine wheel, used to change the direction of liquid flow, causing it to return to the pump wheel again and form a cycle. When the load increases, the turbine speed decreases, and the liquid flows back to impact the guide wheel. The guide wheel generates a reaction force, increasing the torque output of the pump wheel and achieving torque amplification effect.Features: It has the characteristics of torque amplification, good stability, low impact, overload protection, etc. But there are also issues of low efficiency, complex structure, and high maintenance costs.
