Double ball joint refers to the double ball joint spring shock absorber strut front axle, which is a strut device used for shock absorption. This type of shock absorption device can provide unique dynamic handling and flexible steering, and can be applied to lightweight aluminum intelligent applications. BMW's double ball joint spring shock absorber strut front axle is made of aluminum material, which reduces the weight by 30% compared to steel material, significantly lowering the unsprung mass of the vehicle. The strut front axle balances the load between the front and rear axles, affecting the car's suspension and steering system, making it more responsive. When driving on uneven roads, the handling and comfort of the vehicle are improved. Similar to the shock absorption function of shock absorbers, it can suppress the bouncing motion of the suspension springs and enhance the driving smoothness of the car.
