What is the purpose of the ABS block?

Definition of the ABS block

It was the Bosch company that marketed a first version of ABS block in the late 1970s. The ABS block refers to the principle of anti-lock wheels to eliminate, during emergency braking, that the wheels do not lock.

The ABS system quickly

• The magnetic targets: they generate signals read by the sensors, which send these signals to the ABS computer.
• The ABS block: more details below.
• The wheel speed sensors: each of the sensors is placed in front of a rotating gear, which generates a magnetic field variation and induces a sinusoidal signal.

The motor driving a hydraulic pump

It transfers hydraulic energy into mechanical energy.

The ECU

The hydraulic unit

Here are some of the elements that make it up...

• The electronic brake proportioning valve, which is a complementary function managed by the ECU.
• A hydraulic pump whose action moves the fluid stored in the accumulator to the master cylinder thus preventing the pedal from depressing.
• Pressure accumulators which are none other than tanks of pressurized gas used to provide a large flow rate for a fairly short time.
