NRG-Disc Flexible Rubber Couplings
The NRG-Disc isolates torsional vibration occurring at the drive shaft, harmonizes the torque ramp-up and compensates the axial displacement and cardanic angle. Any desired spring rate can be set in combination with special bushings to ensure axial force compensation. This could be achieved by specific cord packages for drive and reverse direction, the use of different cord types, optimized winding processes and rubber compounds. The coupling can be flexibly designed according to the customer’s requirements without any change of geometrical dimensions.
The disc can also withstand the highest torques and is significantly more durable and lighter than current series-produced solutions available on the market, thanks to its specially developed components. High strength steel bushings always ensure a secure screw connection.
Special sleeves separate the cord-packages and an innovative cord construction ensures durability even at high cardanic angles. At 4.5°, the maximum cardanic angle is particularly high, and therefore enables the NRG-Disc to be applied even in demanding installation spaces, without compromising on durability.
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.
