Heavy-Duty EV Rear Axles & Transaxles
For heavy city-logistics transport, large sightseeing fleets, airport GSE tugs, and agricultural vehicles. Engineered to handle high peak input power and punishing load environments under the rigorous IATF 16949:2016 automotive standard.
Tested and certified by the China Merchants Testing Vehicle Technology Research Institute (Report No. QE25WT1G52901) under standard QC/T 533-2020:
- Static Torsional Reserve Factor: Reached 3.55 (Standard requirement is only >1.8).
- Gear Fatigue Life: Completed 300,000+ cycles under full load with zero structural defect.
- Full-Floating Setup: Hub bearings handle all weight load, shielding half-shafts entirely from bending stress.
- Heavy-Duty Braking: Optional Ø240mm/Ø250mm robust drum brakes to guarantee reliable stop times.
