Working principle of wheel hub bearings - Function and fault phenomena, service life and replacement time of wheel hub bearings

An in-depth analysis of the operating mechanism of wheel hub bearings As a key component of transportation vehicles such as cars and motorcycles, wheel hub bearings have the core function of supporting the wheels and significantly reducing the resistance caused by friction between the wheels and the ground, ensuring the smoothness of vehicle operation. To achieve these functions, the operation of wheel hub bearings involves core mechanical principles such as rolling friction, sliding friction, and torque transmission.

The return spring causes the shoulder of the release bearing to always resist the release fork and retreat to the final position.

Since the clutch pressure plate and separation lever operate synchronously with the engine crankshaft, and the separation fork can only move axially along the clutch output shaft,

If the sound increases, you can observe whether there are sparks.

Continue to press the clutch pedal. If the sound disappears, it is not a problem with the release bearing. If there is still a sound, it is the release bearing. ring.

When the free stroke has just been eliminated, a "rustling" or "squeaking" sound appears.

If the clutch release bearing fails to meet the above requirements, it is considered to be faulty. After a failure occurs, the first thing to do is to determine which phenomenon is damage to the release bearing. After the engine is started, lightly press the clutch pedal.

The function of clutch release bearing

The clutch release bearing is installed between the clutch and the transmission. The release bearing seat is loosely sleeved on the tubular extension of the first shaft bearing cover of the transmission.

Clutch release bearing introduction

The clutch release bearing is an important part of the car. If it is not properly maintained and malfunctions, it will not only cause economic losses, but also be very troublesome to disassemble and assemble once, which requires a lot of man-hours. Therefore, clarifying the cause of clutch release bearing failure and maintaining it properly during use are of great significance to extending the life of the release bearing, improving labor productivity, and achieving better economic benefits.

What is the use of release bearings, clutch release bearings, bearing burning damage phenomenon and common reasons.

The so-called release bearing refers to the bearing used between the clutch and the transmission, usually referred to as the "clutch release bearing". When stepping on the clutch, if the shift fork is combined with the high-speed rotating clutch pressure plate, a bearing must be needed to eliminate the heat and resistance generated by direct friction. Therefore, the bearing installed in this position is called the release bearing. The separation bearing pushes the pressure plate to separate from the friction plate, thereby cutting off the power output from the crankshaft.
