Clutch release bearings
Preventing Damage Caused by Sudden High-Speed Rotation
A "clutch" is a device that either transmits driving force from the engine to the transmission or shuts it off, without stopping the engine. JTEKT's bearings are equipped with a centering mechanism to prevent damage caused by sudden high-speed rotation during transmission of the driving force. In addition, some reduce weight by using steel plate presses for the bearing rings.
Functions Required
of Bearings and
the Clutch
Release Structure
Clutch release bearings are used in the part that transfers or shuts off the driving force.
When the driving force is shut off, the clutch release bearing is affected by a strong force from the high-speed rotating diaphragm spring, and starts to rotate suddenly. If there is a significant gap between the rotation centers of the diaphragm spring and the clutch release bearing, the contact surfaces are likely to generate heat and wear, and this greatly impacts the clutch function. Self-aligning clutch release bearings in particular can prevent this abnormal heat generation and wear.
What Are Clutch Release Bearings?
Structure
If there is a significant gap between the rotation centers of the diaphragm spring and the clutch release bearing, self-aligning clutch release bearings prevent abnormal heat and wear. The centering mechanism between the sleeve and bearing absorbs the gap in the rotation center of the diaphragm spring at the start of the clutch release bearing's rotation, and after that the rotation centers of both of them are aligned to suppress abnormal heat generation and wear on the contact surfaces.
Clutch release bearings that use steel plate presses for their bearing rings decrease the overall vehicle weight and contribute to lower fuel consumption.
Self-aligning type
Self-aligning bearings (CBU type: Lightweight type)
Features
- 1.They use grease to increase durability under high-speed rotation, high-temperature, and high-vibration conditions, and allow for a long service life.
- 2.They use seals with excellent sealing performance to prevent grease leakage.
