Clutch release bearing vs throwout bearing

With regard to the discussion of “clutch release bearing” vs. “throwout bearing”, it is important to first clarify that in the context of the automotive industry and clutch systems, these two terms generally refer to the same component, i.e., the bearing used in a manual transmission to assist in the release and engagement of the clutch. In the context of the automotive industry and clutch systems, these two terms usually refer to the same component, i.e. the bearing used in manual transmissions to assist in clutch release and engagement. However, in order to explain more clearly the relationship and differences between them (although in practice the differences are minimal), we can look at the following aspects:

1. Terminological differences

Clutch release bearing: this term emphasizes more the role of the bearing in the clutch release process, i.e. releasing the clutch and disconnecting the power transmission from the engine.

Throw-out bearing: This term describes more the action, i.e. “throwing out” or pushing the release lever or acting directly on the pressure plate to disengage the clutch.

Whether it is a clutch release bearing or a throwout bearing, this component is located between the clutch pressure plate and the clutch fork.

Their main function is the same: when the driver depresses the clutch pedal, it pushes the clutch release fork, which in turn separates the clutch pressure plate from the flywheel, thus cutting off the power transmission between the engine and the transmission.

They are mounted between the clutch and the transmission, maintaining contact with the release fork through mechanisms such as return springs, and ensuring a quick and smooth reset when the clutch is engaged.

2. Role and function of the hydraulic throwout bearing

The main functions and features of the auto hydraulic release bearing in the auto clutch system are as follows:

2.1. Hydraulic operation: Unlike traditional mechanical throwout bearings, hydraulic throwout bearings utilize a hydraulic system to control the engagement and disengagement of the clutch. This means that when the driver depresses the clutch pedal, hydraulic pressure is transmitted to the release bearing, enabling it to smoothly push the pressure plate and disengage the clutch.

2.2. Reduced operating forces: With the hydraulic system, it significantly reduces the amount of force that needs to be applied to the clutch pedal, making it easier for the driver to shift gears, especially in city driving conditions where gear changes are frequent.

2.3. Improved smoothness: the hydraulic system enables more precise control of the disengagement process, ensuring smoother clutch engagement and disengagement, reducing shocks and improving driving comfort.

2.4. Automatic Adjustment: Some designs of hydraulic release bearings may have an automatic adjustment function that compensates for play caused by wear, keeping the clutch system operating efficiently. 5.

2.5. Reduced wear: Due to their precise control, hydraulic release bearings can reduce unnecessary stress on the clutch assembly, thus extending the life of the entire clutch system.

2.6. Improved responsiveness: the hydraulic system responds quickly to driver action, ensuring immediate interruption and resumption of power transmission, which is particularly important in high-performance vehicles.

3. Clutch Release Bearing Structure and Principle of Operation

The clutch release bearing (or throwout bearing) usually consists of a series of balls, races, cages and other components, and works on the principle of a thrust bearing.

When the clutch pedal is depressed, the bearing is thrust and moves forward, pushing the clutch release fork to disengage the clutch. After releasing the pedal, the bearing is quickly reset under the action of the return spring.

4. Clutch Release Bearing Maintenance and Replacement

Since clutch release bearings (or throwout bearings) are subjected to large thrust and friction forces during operation, they are one of the parts of the clutch system that are relatively easy to wear.

Regular inspection and maintenance of the bearing's lubrication condition, wear and the tightness of the bearing housing are essential to keep the clutch working properly.

Once the bearing is found to be damaged or badly worn, it should be replaced in time to avoid further damage to the clutch and the whole transmission system.

5. Clutch release bearing vs throwout bearing:

  - Mainly a difference in terminology, no actual physical or functional difference.

  - In different automotive cultures and regions, people may be more accustomed to using one of these terms.

In general, clutch release bearing and throwout bearing are the same kind of bearing and they serve the same purpose in the clutch system.

Conclusion

To summarize, the terms “clutch release bearing” and “throwout bearing” usually refer to the same component in the clutch system, i.e., the bearing that is used to assist the They are the same component in the clutch system, i.e. the bearing that assists in clutch release and engagement. They are similar in function, role, structure and working principle. Therefore, in practice, these two terms can be regarded as synonymous, just with different names. The two terms can be used interchangeably when discussing automotive maintenance or clutch work.
