Turbocharger Housing Coupling with Biasing Force Against Thermal Loosening

The patent applies preliminary anti-action by introducing a biasing member that exerts a separating force between the turbine housing and bearing housing before thermal expansion occurs. This pre-applied counterforce compensates for the thermal expansion forces that will occur during transient operation, preventing the gripping unit from loosening. The biasing member is configured to apply a force in the opposite direction to the thermal expansion force, thereby maintaining reliable coupling throughout operation.

The patent applies the counterweight principle by using a biasing member that generates a separating force to counterbalance the thermal expansion forces acting on the gripping unit during transient operation. This counterforce allows the gripping unit to maintain a stable coupling without experiencing excessive stress, as the biasing member absorbs and compensates for the thermal expansion effects. The system achieves both reliability and stress management through this force balance.

The patent applies dynamics by replacing the static rigid coupling with a dynamic system that includes a biasing member. This biasing member allows the coupling to adapt to thermal expansion dynamically during transient operation. The system transitions from a fixed rigid connection to a flexible connection that can accommodate thermal changes while maintaining coupling reliability, as the biasing member adjusts the force balance in response to temperature variations.
