Retaining Insert

Subteam: ChassisSubsystem: SteeringAssembly: Steering Wheel Quick ReleaseCars: CR21, CR22, CR25, CR26I, CR26E

Purpose

Retains the quick release balls or pins in the locked position.

Function

Inserts let a soft or composite member accept a fastener or rod end without the load bearing directly on the parent material. In the composite rods the insert transfers axial load into the tube entirely through the adhesive bond, which is why insert length is held at a minimum of 2 x diameter.

Design Process

No part-specific design process is documented. The Steering subsystem design process applies: 1. Kinematics sets steering geometry, Ackermann targets and rack travel. 2. Size the column and shafts for torsional stiffness and for the bearing housing that supports them. 3. Calculate static steering force from the tire and geometry, and check it against anthropometric limits. 4. Design the wheel shell around the button and switch layout and the dash sightline; prototype grips and take driver feedback. 5. Validate steering effort and Ackermann on track, using the alternate tie rod mounts to sweep setups.

Manufacturing Process

Machined, then bonded or welded into the parent part.
