The function of auto clutch release bearing unit is by means of bearing axial displacement connection or cut off the power relationships between the engine and transmission system, so as to complete smooth start, stop and transformation of the automobile gear, and the transmission system overload protection.

Its working in high speed, strong vibration, high temperature and wet stains, under the condition of separating cycle times or even one million times above, therefore, request bearing unit has good strength and toughness, impact resistance, wear resistance and contact fatigue performance, etc., to avoid bearing failure occurs after the abnormal noise and clutch clearance adjustment, as well as causing vibration and noise, and even the problem such as bearing jammed.

In meet the development requirements of the automobile, steel bearing unit in friction and wear resistance and self lubricating ability remains to be enhanced, the service life and reliability should be further improved.

The research content

(1) auto clutch release bearing unit materials and structure analysis of evaluation;

(2) the clutch release bearing design;

(3) using nano ceramic composite materials preparation of clutch release bearing unit;

(4) nano ceramic composite materials bearing unit performance testing and preparation process adjustment;

(5) release bearing test device design and manufacturing;

(6) nano ceramic composites unit bearing life and reliability assessment.

The research target

Using nano ceramic (Al2O3 / Si3N4) composite materials manufacturing auto clutch release bearing, to improve separation of self-lubricating bearing capacity, longer service life and increase its reliability.

Application prospect analysis:

So far, the international ceramic industry has identified several ten kinds of ceramic material used in automobile manufacturing, implemented a series of advantages. Nano technology applied in ceramic material, can further improve the toughness and reliability of ceramic materials, expand the application field of ceramic materials.

This project adopts the nano ceramic composites manufacturing clutch bearings, clutch release bearing self-lubricating ability, extend the service life, increase its reliability.
