Friction drive

From Wikipedia, the free encyclopedia

Friction Drive or Friction Engine is a type of motor that instead of a chain uses 2 wheels on the engine to spin the main wheel. This kind of engine is often used on scooters, mainly go-peds, in place of a chain. Friction drive units provide very smooth motion as the mechanism is designed to virtually eliminate mechanical backlash and hysteresis.

Automobiles using this drive system include:

• The Danish Anglo-Dane
• The French Arista (1912 automobile)
• The British Armadale
• The French Astra
• The Swedish Allvelo
• The Danish Bukh & Gry
• The American Davis Totem
• The Ner-a Car
• The Friction Drive Unit
