Steering Column Collapse

Uses a tolerance ring to provide axial resistance in the steering column during a vehicle collision.


Benefits include:

• Allows use of standard tubing - increased tolerances
• Improves NVH properties of overall assembly
• Accurate and precise axial forces over tolerance range
• Fewer components when compared against EA Straps
• Easy to assemble

Tolerance Rings are radial spring fasteners
that are press fitted between two mating components. This generates a retention force that fixes those components together, whilst also satisfying other functional requirements such as Torque Drive, Overload Protection, NVH Performance and Differential Thermal Expansion.


Fasten annular components
Reduce noise & vibration
Compensating for thermal expansion
Predictable & repeatable slip
Avoid resonance frequencies
