DREIKA^®– as fastener application

1. Assembly with clearance

2. Compensation of the pitch by turning

3. Distortion

The DREIKA - Technology uses a mathematical logarithmic spiral as a surfaceprofile. The interface with this technology provides a self locking system, with surface pressure.Furthermore between the self locking wedges there is a homogenous surface pressure thatproduces a powerful transmission of tightening and loosing torques - transmission in bothdirections.

Connection with a steering system

One of the best advantages is an independent ratio of tightening torque andpreload. In this application it was necessary to preload precisely with low axialforces a plastic slide bearing and to have maximum loosing torques. This systemwas the only solution for this technical requirement. This system has been approved for the new S-Class of DaimlerChrysler.
