What is the ABS block?

What is the purpose of the ABS block?

It was Bosch that developed a first version of ABS block in the late 1970s. The principle of the ABS system is rather well understood by the general public: it simply prevents the wheels from locking when the driver abruptly presses the brake.

Focus on the ABS system

Before explaining the ABS block, it is necessary to understand the entire ABS system. We can notice for the BMW 4 series vehicle ...

• The wheel speed sensors: each of the sensors is placed in front of a rotating notched wheel, which generates a magnetic field variation and induces a sinusoidal signal.
• The ABS block: more details below.
• The magnetic targets: they are, depending on the car models, integrated into the wheel bearings.

The ABS block

Different elements of the BMW 4 series car ABS block to be understood including:

The hydraulic unit

Here are some of the elements that make it up:

• Solenoid valves that limit the pressure of the brakes of each wheel.
• The electronic distributor that nuances the pressure on the rear wheels.
• Pressure accumulators that are none other than pressurized gas tanks that can hold a variable volume of a pressurized liquid.

The hydraulic motor

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

The ECU

This is the part that receives an information that comes from the brake pedal.
