How to clean abs bearing gear ring?
The cleaning method of ABS bearing gear ring mainly includes disassembling the gear disc and sensor, and thoroughly washing with special cleaning agent to ensure that every detail is clean.
When cleaning the ABS bearing gear ring, it is first necessary to separate the gear disk from the sensor, so as to ensure that the sensor will not be damaged during the cleaning process. After separation, use a special cleaning agent to thoroughly rinse the gear ring to ensure that all oil and dust are removed, so that the gear ring is clean again. The key to this step is to use the correct cleaning agent and the correct method of operation to avoid damage to the sensor or incomplete cleaning.
In addition, when cleaning the wheel speed sensor, the following points need to be noted:
Select the appropriate cleaning agent to ensure that it will not cause damage to the sensor.
Be careful during cleaning to avoid damaging the sensor.
Rinse thoroughly after cleaning to avoid residue of cleaning agent.
Please disconnect the power supply before cleaning to ensure safety.
If you are unsure of your ability to operate, it is recommended to seek professional help.
In short, cleaning ABS bearing gear rings and wheel speed sensors is an important step to ensure vehicle safety and performance. The correct cleaning method and precautions can extend the service life of the car and improve driving safety .
As we all know, if the ABS system wants to work properly, it must continuously collect the wheel speed data, and the gear ring is an important part to transmit the wheel speed data to the sensor.
The ABS gear ring is installed on the inside of the wheel hub and rotates with the wheel hub during normal operation. The sensor fixed on the axle determines the wheel speed by judging the speed of the gear ring, and transmits the collected data to the ABS computer.
It can be said that the gear ring is one of the most important parts in the ABS system. But it is this important component that is often overlooked by everyone.
● The gear ring needs to be clean, otherwise it will affect the wheel speed signal collection
The gear ring is installed on the inside of the wheel hub, and it will inevitably be polluted by some grease when working normally, coupled with the dust that the brake pads and brake drums wear down, over time, the tooth groove on the surface of the gear ring will gradually be filled with these sludge.
Many card friends think that the gear ring is contaminated by mud will not affect the performance of the ABS system, in fact, this view is wrong. Because the sludge is mixed with a large number of metal debris, these metal debris will have a great impact on the data collected by the sensor. In order for the ABS system to work normally, the oil on the surface of the gear ring must be cleaned during maintenance.
Ring cleaning is relatively simple, with a brush dipped in gasoline, diesel or carburetor cleaning agent and other solvents can be easily cleaned. It should be noted that when cleaning the gear ring, the oil will inevitably fall into the brake drum, and finally, it must be cleaned, otherwise it will lead to a serious shortage of braking force, affecting driving safety.
● Ring installation is not complicated thermal expansion and contraction easy to solve
In addition to how to clean the cleaning ring, let's talk about how to install the ABS ring. Many friends will find that when installing ABS in the later period, the wheel of the original car is not with a tooth ring, and can only be installed by itself.
The gear ring and the wheel are combined together by interference fit, under normal circumstances, can not be directly installed, must be installed through the principle of thermal expansion and contraction. In order to save time, many repair shops often use gas cutting guns to heat the gear ring. Finally, although it can be successfully installed, due to uneven heating of the tooth ring, it will be distorted after installation, resulting in the ABS system can not work normally.
It should be noted that after the gear ring is installed, it must be rotated by wearing thermal gloves, only in this way can the installation accuracy be ensured.
ABS is a complex whole, and any problem in any link will lead to unpredictable consequences. We must pay more attention to the daily maintenance or later installation of ABS. Only in this way can the ABS system be brought into full play.
