Electric Power Assisted Steering (EPAS) belt adjustment systems

The volume manufacture of belt driven EPAS units has only been possible by the ability to set the belt tension accurately. Due to packaging constraints the belt is very short with belt spans less than 100mm. Early attempts at setting belt tension by either the use of load cells or torque measurement proved to be unsuccessful which has led to some of the world's leading EPAS manufacturers to come to CLAVIS for belt tension measurement equipment. EPAS belts provide a unique technical challenge. CLAVIS has met this challenge. For reasons of confidentiality no images of this equipment can be displayed with their matching EPAS units.
