An ABS gear ring, also known as an ABS reluctor ring or tone ring, is a component of the Anti-lock Braking System (ABS) in an automobile. It is typically a toothed or serrated ring made of metal, usually steel, that is mounted on a rotating part of the vehicle, such as the wheel hub or axle shaft.
The purpose of the ABS gear ring is to provide information to the ABS system about the rotational speed of the wheel. It works in conjunction with the ABS sensor, which detects the rotation of the gear ring and sends signals to the ABS control module.
As the wheel rotates, the ABS sensor picks up the changes in the teeth or notches on the gear ring, generating electrical impulses that the ABS control module uses to determine the speed and behavior of the wheel. This information is crucial for the ABS system to monitor and control individual wheel braking during sudden stops or situations where wheel lock-up might occur.
The ABS gear ring plays a vital role in ensuring the effectiveness of the ABS system in preventing wheel lock-up and maintaining stability during braking.
