The problem and how to solve it

The Problem: Leaky Seals in Rotary Dampers

Traditional rotary dampers, while compact and efficient, suffer from a critical flaw: seal leakage. These dampers rely on seals to contain pressurized fluid, but these seals are prone to wear and tear, leading to:

  • Costly maintenance: Frequent replacement of seals adds to the overall expense.
  • Performance degradation: Leaks reduce damping efficiency, compromising performance.
  • Reliability issues: Unexpected failures due to leakage can cause safety concerns

This problem has plagued industries ranging from automotive to prosthetics, limiting the potential of rotary dampers.

 

The Solution: INVENTUS‘ Magnetic Seal

Inventus has engineered a groundbreaking solution: magnetic sealing. By harnessing the power of magnetism, we’ve eliminated the need for traditional seals altogether. This revolutionary approach offers:

  • Unmatched durability: No more wear and tear, resulting in significantly longer service life.
  • Absolute leak prevention: A hermetically sealed system ensures consistent performance and reliability.
  • Reduced manufacturing costs: Simplified design with fewer components and less stringent manufacturing tolerances.

Our magnetorheological rotary damper represents a paradigm shift in damping technology, offering superior performance, reliability, and cost-effectiveness.

Consists of:

Magnetic and better tightness

No sealing lips

Integrated valve

Reduced production costs

Design

The spring would have to be separate, as in the sports car there were leaf springs, or as an integrated torsion bar.
 
The rebound stop can be integrated in the rotary damper (gives relatively high forces – this is how the anti-roll system is designed) or on the lever arm.
 
Here is the CAD image of the adaptive MRF rotary damper with lever arm from the historic Ferrari, which has been designed and tested in several races:

The INVENTUS „Rotary vane“ operating principle as a swivel vane structure for chassis dampers enables high torques in a small installation space. The INVENTUS „Rotary Vane“ was also designed as an adaptive roll stabilizer and tested in a BMW X6 over several thousand kilometers.
