01 Technical Highlights
1.High-performance Transmission System
A high-performance transmission system has been developed. Low-friction high-speed bearings are selected, and gear parameters are optimized using a multi-objective approach. The transmission efficiency and NVH performance are leading in the industry.
2.Multi-oil Passage Main Reducer Housing
A multi-oil passage main reducer housing has been designed. The housing structure is optimized through lubrication simulation and testing to improve the reliability of the reduction housing and lubrication adaptability. It can be compatible with both front-mounted and rear-mounted motor schemes, offering high adaptability.
3.Efficient and Reliable Maintenance-free Wheel End System
A maintenance-free wheel end system is adopted, which can achieve a longer maintenance cycle for the axle assembly, improve operating efficiency, and reduce maintenance costs over the life cycle.
4.Special Bridge Housing Design for Electric Drive Axles
A special bridge housing for electric drive axles has been developed. It has small load deformation, strong load-bearing capacity, and overall lightweight design. This reduces the impact of bridge housing deformation on the transmission system and improves system reliability.
02 Economic Practicality
Reduced Maintenance Costs: This axle optimizes the transmission system and housing of the main reducer, increasing the overall bridge operating mileage, enhancing the reliability of the drive system, and improving the vehicle’s attendance rate, thus reducing the maintenance costs for the entire vehicle.
Diverse Application Scenarios: This axle is suitable for working environments ranging from -40°C to 45°C, demonstrating extremely strong scene adaptability.
