Audi Q5 8R - Repair abs pump

How the ABS block works

Vehicle stability with the ABS block

It was the German company Bosch that marketed a first version of the ABS block in the late 1970s. The principle of the ABS system is fairly well understood by the general public: it simply prevents the wheels from locking up when the driver presses the brake a little too hard.

The ABS system to prevent wheel lockup

The ABS block is a part of the overall ABS system. There are for the Audi Q5 8R vehicle manufacturer ...

• Magnetic targets: they vary the output signal, which is in the form of a square wave signal of variable frequency.
• The ABS block: how is it composed? Let's see it in more detail below...
• The wheel speed sensors: each sensor is placed in front of a notched wheel which induces a sinusoidal signal whose quality depends on the speed of rotation of the wheels.

The ABS block

Let's look at some of the elements of the ABS block of the Audi Q5 8R car ...

The hydraulic unit

It is made up of several components including:

• Solenoid valves with each wheel having an intake solenoid valve and an exhaust solenoid valve.
• A hydraulic pump that prevents the pedal from sinking during ABS regulation.
• Pressure accumulators which are pressurized gas tanks used to provide a large flow rate for a fairly short time.

The motor driving a hydraulic pump

It uses the oil flow that is pushed into the hydraulic system by a hydraulic pump and transforms it by a rotary motion to drive another device such as the differential or another pump, etc.

The ECU

As soon as a wheel tends to lock, it guides the solenoid valves and hydraulic pump.
