Forged wheel hub + base: the core support for lightweight safety of new energy vehicles

With the rapid development of the new energy vehicle industry, cruising range, safety performance and vehicle durability have become the core considerations for consumers when purchasing cars, and have also become a key competition track for car companies. As the core load-bearing structure of the wheel, the wheel hub and the base (including key support components such as the wheel hub base and battery base) jointly bear the key mission of supporting the weight of the vehicle body, transmitting driving power, and buffering driving impacts. The wheel hubs and bases made of forging technology, with the triple core advantages of "lightweight + high strength + fatigue resistance", perfectly meet the stringent requirements of new energy vehicles for low energy consumption and high safety, and have become standard core components of high-end new energy vehicles.

1. Why do new energy vehicles must choose forged wheels and bases?

Because new energy vehicles are equipped with large-capacity battery packs, their body weight is 10%-20% higher than that of traditional fuel vehicles. At the same time, they have extreme requirements for energy consumption control - for every 10kg reduction in body weight, the cruising range can be increased by 5-8km. Wheel hubs and bases produced by ordinary casting processes have three fatal flaws and are difficult to meet the needs of new energy vehicles:

The weight is too high: the density of the casting material is low, and more materials need to be used to ensure the strength, resulting in excessive weight and a direct drag on battery life;

Insufficient strength: The grain structure is loose, there are hidden dangers such as pores and blisters, and it is easy to deform and crack under high-frequency starting and stopping and complex road conditions;

Poor fatigue resistance: When subjected to alternating loads for a long time, metal fatigue is prone to occur, affecting driving safety.

The forged wheel hub and forged base achieve a leap in performance through high-temperature forging processes:

Extreme lightweight: Forging makes metal grains densely arranged, which reduces the weight by 20%-30% compared with cast products at the same strength, directly reducing the driving energy consumption of new energy vehicles and extending the cruising range;

Super load-bearing capacity: The tensile strength can reach more than 600MPa, and the torsion and impact resistance are increased by 50%. It can easily bear the weight of new energy vehicles and the impact of complex road conditions, especially suitable for the heavy load requirements of the battery base;

Ultra-long durability: Continuous and complete metal streamline design, combined with tempering and quenching heat treatment, improves fatigue resistance by more than 3 times, and the service life can reach 10 years or 200,000 kilometers;

Precise fit: Near net shape process + precision machining, dimensional tolerance is controlled within ±0.02mm, perfectly fits the wheel hub motor, bearings, and battery pack, reducing transmission loss and noise.

2. Core application scenario: all-round adaptation of forged wheel hub and base

With their excellent adaptability, forged wheels and bases have become the core choice for all types of new energy vehicles, covering all scenarios from family cars to commercial vehicles:

Pure electric passenger vehicles (sedans/SUVs), new energy commercial vehicles, high-end new energy models (luxury pure electric/supercars)

3. Conclusion

Under the development concept of "reducing weight, increasing efficiency, and putting safety first" in the new energy automobile industry, forged wheels and forged bases have become core components for improving the overall performance of the vehicle. Its lightweight characteristics directly help improve battery life, its high-strength advantages build a secure line of defense, and its long-life performance reduces operation and maintenance costs. Both car companies and end users can gain core value from it.
