The ABS block

The ABS block of the car manufacturer Renault Clio 4 consists of, among other things, the following elements.

The hydraulic motor

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

The hydraulic unit

It is made up of various elements including...

• Pressure accumulators which are none other than tanks of pressurized gas used to provide a large flow for a fairly short time.
• A hydraulic pump whose discharge is the cause of the vibrations felt at the pedal.
• Solenoid valves of which each wheel is equipped with an intake solenoid valve and an exhaust solenoid valve.

The ECU

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