In this way, the sleeve is relieved from tensile and compression loads, and is only exposed to shear stress. The result is optimized wear characteristics, since elastomers can bear the drive shaft load much better. An optimized sealing function increases the NVH behavior of the sleeve.
The spherical form of the elastomer track comprises an outer deep-drawn sleeve and an inner sleeve of plastic or bronze, optimized for decreased wear characteristics, higher durability and better driving comfort.
