Wear is a particular challenge. If it is too high, the propeller shaft will no longer be centered correctly. This can lead to imbalances that can be heard inside the vehicle. Consequently, the engineers at Vibracoustic transformed the traditional, cylindrical center sleeve into a spherical center sleeve. Here, the elastomer track is spherical, relieved of tensile-compression stresses, and only exposed to shear stress. Wear is reduced because elastomers can bear this tension much better, and the driver benefits from durability and greater driving comfort.
