FAST New Energy Electric drive series have different models, with code E in the model name indicates ETM transmission.
Based on the advantages of technology research and development in the traditional transmission field for many years, Fast Group has independently developed electric drive products according to customer needs through many new energy market researches. Compared with pure electric direct drive products, the structure is more compact, the control is more comfortable, and the climbing The slope is more powerful, the energy saving is more significant, the system is more reliable, and the economy and applicability of the vehicle are further improved. The products cover the fields of commercial vehicles and construction machinery in an all-round way.
Advantages of Fast Torsional Damper (Special for AT)
It is synchronized with CMI’ advanced design and sophisticated manufacturing, adapts to harsh working conditions, and has high-intensity and heavy-duty work capabilities.
The Holset wastegate valve makes the low speed performance more perfect and the power performance better.
The cylinder block and cylinder head adopt integrated design to prevent the occurrence of engine water and oil leakage. The parts are 40% less than other similar engines, and the failure rate is greatly reduced.
The cylinder liner adopts a platform mesh honing design, which effectively prevents oil leakage with a perfect geometric structure, and adopts advanced technology such as new piston ring components and gasket crimping molding to reduce oil loss.
Using forged steel camshaft and crankshaft, high-strength cylinder design, many parts are cast on the cylinder, with high rigidity, high pressure resistance, good reliability and longer service life.
