The Application of Tolerance Rings in Anti-Theft Steering Column Assemblies 940868

The use of tolerance rings as a torque limiting device between a shaft and a locking sleeve in steering column assemblies will be reviewed. In the light of rapidly escalating auto thefts, changes in European statutory requirements, and the ever present need for cost reductions, tolerance rings have demonstrated major benefits to users around the world. First principles of the design of tolerance rings will be presented along with their features such as the relationship between torque, assembly force, radial load capacity and spring compression.
Different actual and possible steering column configurations will be shown together with relevant test results and other data. The latest developments in tolerance rings and recent improvements in terms of better torque performance, reduced space requirements and cost will also be presented. Planned changes in EC legislation will be reviewed and compared with other regulations.
