After the rigorous selection of all aspects of China's Top Ten Chassis, Alpha T won the "2022 China Top Ten Chassis" and "Best Green" awards with its excellent chassis performance and strong platform expansion ability of chassis architecture.
The selection of China's top ten chassis is the first professional award in the field of chassis in China jointly created by China Automotive Technology and Research Center Co., Ltd., industry authoritative institutions, universities and other technical forces, which has high authority. The selection focuses on a number of indicators such as technological advancement, automobile brand awareness, market share, and consumer attention, and scores are based on four parts: chassis product definition, chassis product development, chassis product performance, and chassis product display. In the end, the Alpha T won unanimous praise from the judges and experts for its outstanding performance in chassis performance and modular development, and finally won the grand prize.
Being able to stand out from many participating models and win the award shows the strength of Extreme Fox in chassis research and development and tuning, and once again proves that Extreme Fox has worked hard in places that consumers cannot see, ensuring the high quality of products.
IMC architecture platform: modular design has obvious advantages
As an all-terrain performance pure electric SUV, the Extreme Fox Alpha T was born in the IMC architecture platform, the first commercial platform equipped with 5G technology in the global new energy vehicle industry, with four characteristics: super expansion, super intelligence, super interaction and super evolution. Through the modular chassis structure, Extreme Fox simultaneously creates three major platforms of "large, medium and small", meeting the full coverage from A0 to C-class, from sedan, SUV and Cross models. A variety of suspension modules, steering modules, brake modules, driving modules are developed extensively, and chassis modules of different models are flexibly configured, so that the chassis platform rate reaches more than 80% in the industry.
In terms of suspension, the front suspension of the Extreme Fox Alpha T adopts MacPherson independent suspension, the front lower swing arm is turned forward, and the rear suspension adopts H-arm multi-link suspension, which occupies little space in the X direction, which is conducive to battery arrangement on the basis of ensuring chassis performance, which provides hard conditions for the placement of the Extreme Fox Alpha T93.6kW·h large-capacity battery module, ensuring a reserve of 653km long endurance. At the same time, the application of front and rear frame subframes is also conducive to motor arrangement.
In terms of steering, the Extreme Fox Alpha T applies electric adjustment tube strings, which can realize the four-way electric adjustment of the steering wheel up and down, front and back, and the memory and welcome function of the steering wheel, which not only pays attention to comfort but also reflects the sense of ceremony; The steering system adopts electric four-way regulating column + double pinion electric power steering (DP-EPS), and retains and upgrades the fully redundant geared electric power steering (R-EPS) interface, which can realize intelligent driving functions above L3 level, which is at the leading level in the industry.
In terms of braking, the Extreme Fox Alpha T adopts a two-box brake-by-wire system, supports L2.5 intelligent driving, X-shaped circuit layout, front two-cylinder cast aluminum ventilated disc brakes, and has the advantage of leading braking distance of 100 kilometers for SUVs of the same class. Based on the IMC intelligent module architecture, the much-watched Extreme Fox Alpha S new HI version is upgraded to a One-box solution, with power redundancy, communication redundancy, wheel speed redundancy, power redundancy, and ABS redundancy to create an intelligent chassis architecture based on redundant by-wire control, which can support L4 high-end intelligent driving, which is based on the technical foresight layout of Extreme Fox on the chassis.
Lightweight material selection and structural design "Weight reduction" does not reduce safety
As we all know, the Extreme Fox Alpha T adopts the upper steel and lower aluminum structure, which perfectly balances lightweight and safety. In terms of material selection, the Extreme Fox Alpha T adopts all-aluminum alloy subframe and swingarm structural parts, hollow stabilizer bars, and high-tolerance stress springs, which reduces the overall weight by about 20% through the design and application of lightweight materials, processes and structures, providing more protection for vehicle collisions while being lightweight, which is also an important factor for it to obtain the C-NCAP five-star rating and the C-IASI index excellent level. In addition, the vulcanization design of stabilizer bar and stabilizer bar bushing also greatly improves NVH performance.
In terms of structure, the Extreme Fox Alpha T also adopts a highly integrated lightweight structure design, integrated bearings can replace bearings and spring disc combinations, flat spring discs and high-strength lateral force springs reduce weight by 20% for traditional designs; After the brake pedal has been optimized for multi-wheel structural weight reduction, the weight of its base is reduced by 40% compared with traditional steel structure products. The weight of the steering knuckle assembly is 40% lighter than that of traditional cast iron products; The weight of the suspension can be reduced by 30% compared with traditional cast aluminum products; Forged wheels are 15% lighter and lighter. It can be said that the "lightweight" of the Extreme Fox Alpha T does not miss any details that can "reduce weight".
Magna Top Tuning High intensity testing guarantees quality
Since its launch, the Extreme Fox Alpha T has been praised for its handling and ride comfort that a high-end model should have, which shows the solidity of its chassis strength, which is not unrelated to Magna's top manufacturing technology and tuning.
With 110 years of history and experience in the production and manufacturing of 3.7 million top luxury cars such as Mercedes-Benz, Magna has integrated the MAFACT production process and quality system into the production of the Alpha T, achieving high automation, high precision and high efficiency in the modular assembly of chassis and powertrain, ultra-high-precision adjustment equipment, and torque calibration equipment, laying a high-quality foundation for the Alpha T.
In addition, the chassis of the Extreme Fox Alpha T has also been fully verified from the component level, to the system level, and then to the vehicle level. Among them, the parts have been verified by 720,000 kilometers of user mileage, the suspension, steering and braking systems have been verified by 480,000 kilometers of user mileage, the chassis brake control has passed 12 test sites, more than 100 working conditions, 26 kinds of road surfaces, 36 functions, 8 times of acceptance, and the whole vehicle has been verified by 240,000 kilometers of user mileage. Whether it is the Turpan Basin with a surface temperature of 80 °C, the Golmud Plateau at an altitude of 4,700 meters, or the Heihe River with a temperature of minus 40 °C, the Extreme Fox Alpha T has passed the test of vehicle performance test, environmental adaptability test and basic vehicle system calibration, and its chassis durability and reliability are excellent enough.
