Reinforced Rear Axle - as stable as a rock
The traditional differential assembly is prone to oil leakage and tooth damage over time, especially when carrying heavy loads. Our 48V 3kW rear axle assembly features an integral axle housing design, with spiral gears and precision bearings. After a three-thousand-kilometer test, the transmission efficiency remains above 94%, and the failure rate is 60% lower than that of ordinary products. It is particularly suitable for heavy-duty scenarios such as delivering tricycles and agricultural transport vehicles, and when used with the Dual Drive Motor Controller system, it can still maintain stability when carrying a load of 800 kilograms.
Three major advantages of the product
- Integral forged axle housing, with an increase in torsional strength by 50%
- Sliding gears + grinding process, with operating noise reduced to below 65 decibels
- Double oil seal labyrinth structure, completely solving the problem of oil leakage
Maintenance points
- Replace the gear oil after 300 kilometers of first use
- Check the dust shield of the half shaft for damage every month
- Check the bearing clearance every quarter during heavy-load operation
Q&A：
Question: Can it be compatible with the Electric tricycle control system? Answer: Perfectly compatible with the Electric Tricycle Control Device, supporting electronic differential function.
Question: How is the waterproof performance? Answer: The Waterproof Electric Tricycle Controller version uses multi-layer sealing. It won't affect usage even if submerged to a depth of half a meter.
Question: Is it easy to replace by oneself? Answer: Special positioning tools are provided. After removing the old frame, the installation can be completed within 2 hours.
Question: What is the maximum slope carrying capacity? Answer: With a full load of 800 kilograms, it can climb a 20-degree slope. It can still operate even with short-term overload up to 1.2 tons.
Question: Is it suitable for modified vehicles? Answer: The Electric Scooter Controller system requires an adapter to be added. We provide a matching conversion module.
Question: What is the warranty policy? Answer: The frame has a three-year warranty, the gear set has a two-year replacement policy, and 24-hour technical support is provided.
This rear axle assembly has undergone 100,000 times of bench testing. All gears adopt the German carburizing process. Special reminder: When replacing, please use 80W-90GL5 gear oil. Do not mix different types of lubricants. Currently, 50 logistics companies have bulk purchased it, and the longest usage record exceeds 200,000 kilometers without major repairs.
