Aviation series Forged Aluminum Alloy Hub kg Every spring reduces mass 4 kg This corresponds to a reduced maneuvering gain. M Porsche Spyder Magnesium alloy hub adopts honeycomb dummy structure, and the weight is only kg The 43% inertia resistance is lower than the conventional casting hub. Carbon fiber hub is capable of raising the heat dissipation rate to 2.5 times by continuous curve, but it is necessary to watch the embrittlement point of brittle critical point of - 10 ℃ or less. Don't forget to comply with the 7% rule when remodeling. Wheel quality should not exceed 107% of the original factory parts. Otherwise, the suspension frequency is destroyed.

BMW M 4 GTS の Y The type spoke is not a aesthetic design, and its angle of 16 ° can be induced by inducing airflow to form vortices, thereby improving the cooling efficiency of the brake system by 28%. Spinning casting hub R The concentration of stress concentration decreased by 60% compared with the direct spoke design. The waterproofing rate of the exclusive hub of the winter tire must be controlled from 25% to 30%, and it can guarantee the automatic fall of the snow mass and does not affect the structural rigidity. Hidden hub cover cm² Reducing the area per wind, reduces wind speed by 3 decibels.

The 19 inch wheel hub contains 35 plate tires, and the shape of the tire wall is 40% lower than the 18 inch combination, but 17% of the crushing capacity is lost. A modified ring should not be misunderstood as "big is good". As the wheel diameter of 1 inch is increased, the crushing speed of the steering mechanism is increased by 22%. The forged bolt of the performance vehicle is not dazzling technology, and its taper angle tolerance is controlled to ± 0.1 degrees, and it is 3.8 times stronger than the conventional bolt. Remember "hub temperature laws": you must check the dynamic balance weight if the hub center temperature after intense operation is less than 75 degrees Celsius.

3 D The printed titanium alloy hub is breaking the strength limit, and the star man rim of the bugarditiron can withstand a 12 ton radial load. Graphene coating technology gives the hub surface hardness 9 H The level reached the level, and the impact damage rate of the masonry fell by 90%. In the future, the liquid metal hub enters the experimental stage, and the self-healing function after the collision can hold the shape memory between - 20 ° C. and 150 ° C. However, remember that any advanced technology needs to make a "hub ECG" periodically. Detecting an inner microcrack with an ultrasonic detector is a dead line that cannot be seen with the naked eye.
