Nonlinear Torsional Coupling for Torque Transfer and Vibration Insulation

The coupling employs a non-linear resilient arrangement whose stiffness characteristic changes dynamically with displacement. At small displacements (normal operation), the coupling exhibits high stiffness to transmit static torque effectively. At larger displacements (vibration conditions), the stiffness reduces to provide vibration insulation. This dynamic stiffness adaptation resolves the contradiction between torque transmission and vibration insulation.

The patent utilizes a non-linear spring characteristic with degressive stiffness, where the spring rigidity parameter changes as a function of displacement. The resilient arrangement is designed such that the stiffness parameter is high at the operating point for torque transmission but decreases for larger amplitude vibrations, thereby providing both static torque transmission and vibration insulation without requiring separate components.

The patent merges the torque transmission function and vibration damping function into a single non-linear resilient arrangement. The non-linear spring characteristic inherently provides both static torque transmission capability and torsion vibration damping without requiring separate damping components. This integration eliminates additional parts, reduces device complexity, and maintains compact structural space.

The non-linear resilient arrangement serves multiple functions simultaneously: it transmits static torque, damps torsion vibrations, and provides mechanical coupling. This multi-functional design eliminates the need for separate damping components and reduces overall device complexity while maintaining effective vibration insulation.

The patent combines torque transmission and vibration damping functions into a single non-linear resilient arrangement, eliminating the need for separate damping components. This reduces the number of parts to manufacture, assemble, and maintain, thereby reducing manufacturing costs while providing effective torsion vibration damping.

The non-linear resilient arrangement provides multiple functions (torque transmission, vibration damping, mechanical coupling) in a single component, reducing overall manufacturing complexity and cost compared to using multiple separate components for each function.
