Cars go faster and faster and have more and more weight. It's even harder to slow them down.
Currently, drum and disc brakes are used on passenger cars. Because disc brakes are more effective, newer car designs use them on the front and rear wheels. However, ever heavier vehicles require a more efficient braking system. Until now, designers have increased the diameter of the brake discs, hence the tendency to increase the diameter of the rim of the road wheels - but this cannot be done indefinitely.
For over a year now, a new type of disc brake has been available that could prove to be a breakthrough solution. It was called ADS (pictured).
The classic disc brake works in such a way that the rotating disc is compressed by friction linings (linings) located on both sides. Delphi suggests doubling this layout. Thus, the ADS consists of two disks rotating around the outside diameter of the hub. Friction linings (called pads) are located on both sides of each disc, giving a total of 4 friction surfaces.
In this way, the ADS achieves a braking torque 1,7 times greater than that of a traditional system with a single disc of the same diameter. The wear and ease of use is comparable to traditional brakes, and the oscillating disc concept helps to eliminate the problem of lateral runout. In addition, the dual disc system is easier to cool, so it is more resistant to thermal fatigue.
ADS requires half the braking force of conventional disc brakes, so you can reduce the amount of force or stroke on the brake pedal. When using ADS, the weight of the brake system can be reduced by 7 kg.
The success of this invention depends on its dissemination. If there are car manufacturers who choose this solution, its production will increase while reducing costs. So it was with other inventions, such as the ESP traction control system. It has been widely used since it was installed on Mercedes-Benz A-series cars.
