SUMMARY

Friction without wear is a theoretical concept primarily discussed in the context of mechanical heat generation. The forum participants explored the possibility of purely mechanical vehicle brake designs that claim zero wear, with a focus on traditional methods rather than electrical solutions. While electric 'eddy' brakes are mentioned as a near solution, they still incur some wear on components. Ultimately, the consensus is that wear is an inherent aspect of friction in mechanical systems.

PREREQUISITES
  • Understanding of mechanical friction principles
  • Familiarity with vehicle brake systems
  • Knowledge of heat generation in mechanical systems
  • Awareness of eddy current braking technology
NEXT STEPS
  • Research the mechanics of friction and wear in materials
  • Explore advancements in mechanical brake designs
  • Investigate the principles of eddy current brakes
  • Examine case studies on zero-wear brake technologies
USEFUL FOR

Mechanical engineers, automotive designers, and anyone interested in the mechanics of friction and brake system innovations.

Friction without wear, does it exist? This would be mechanical heat generation without wear. If so what is the mechanism by which it works? Does anyone know of any new purely mechanical vehicle brake designs which claim zero wear for example. Nothing electrical please.

I think you answered your own question there.

Electric 'eddy' brakes are really as close as you'll get. (Strictly speaking there's wear on the components themselves, but nothing in the way you're intending.)

Otherwise there's always wear.
