What is the ABS block?

What is the purpose of the ABS block?

It is not always known, but the ABS system was first developed for airplanes in the 1920s: it was necessary to prevent skidding on landing. The acronym ABS comes from the German "Antiblockiersystem". It is an anti-lock wheel system that keeps the vehicle under control in case of sudden braking.

The ABS block

Let's look at some of the elements of the ABS block Audi RS7 Sportback:

The hydraulic unit

• Solenoid valves that regulate the brake pressure of each wheel.
• Pressure accumulators, which are none other than tanks of pressurized gas used to provide a large flow rate for a fairly short time.
• A hydraulic pump whose action allows the liquid accumulated in the accumulator to be pumped back to the master cylinder, which prevents the pedal from sinking.

The ECU

It receives the information that comes from the brake pedal.

The motor driving a hydraulic pump

It is a member that transforms a flow rate into rotational speed and a pressure into operating torque. The motor's rotational speed is proportional to the flow rate that feeds it.
