Spherical Center Sleeves
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.
About Centering Devices, Isolators & Dampers | Power Train
Centering devices, isolators and dampers solve vibration-related challenges deriving from the torque fluctuations and natural frequencies of the drive shaft in rear- and all-wheel drive vehicles, where the drive force must be transferred to the rear axle. Rotary dampers, flexible couplings and centering devices help counteract unwanted noise and vibrations from the drive shaft.
Our product portfolio includes flexible power train couplings and damping devices like the NRG-Disc (New Rubber Generation Disc), Tube-in-Tube or Drive Shaft Dampers. They smoothly transfer drive forces to the rear axle and reduce vibrations deriving from the torque fluctuations and natural frequencies of the drive shaft.
In addition to elastic decoupling elements, rotation dampers can be used to effectively reduce system-related resonance effects of the drive shaft.
Center Sleeves, Spherical Center Sleeves and Center Bearing Supports help align the drive shaft and allow flexible movements of the drive shaft while being constantly exposed to high rotational speeds.
In addition, when used as tuning parts already during the early development phase, isolators and dampers help improve the structural behavior of vehicle components and generate weight savings.
