AI Technical Summary
In traditional release bearings, the direct contact between the outer ring and the shift fork during clutch operation leads to wear and deformation, shortening the service life.
An elastic connection structure, including a sliding block, a plug block, and a plug post, is provided in the groove of the bearing outer ring to realize the elastic plug connection between the shift fork and the outer ring. A lubrication filling box and capillary holes are provided on the outer ring to achieve continuous lubrication by utilizing the principles of capillary penetration and thermal expansion pressure difference.
The buffer fork absorbs the impact force during operation, reduces wear, improves lubrication efficiency, and extends the service life of the release bearing.
