Steering Column Intermediate Shaft

Uses a tolerance ring to mount two parts of the intermediate shaft whilst controlling the axial forces during a vehicle collision.


Benefits include:

• Splined shaft allows torque transmission whilst tolerance ring provides collapse force
• Collapse force can be verified during assembly process
• Good performance over a range of component tolerances and operating temperatures

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
Overload protection
