...
- Steering columns will have to use splined stock to maintain rotation between the wheel and all components when the steering column collapses (and to connect to u-joint).
- All shafts below the rack will have to be threaded to connect to components since they need to be threaded, the shafts should be made of steel.
- All other components in the system can be made from aluminum.
- Probably going with the nylon shear pins we had on MSXII, unless better alternatives can be found
Plan Going Forward
| Task/Component | Assigned to | Details |
|---|---|---|
| Steering Arm | Currently using placeholder shape for steering arm, will likely be that size and shape, requires a connection between SA and upright. | |
| Steering column | Detailed cad of connections/spline | |
| Steering column mount | Larry Li (??) | Steering column requires mounting solution to horizontal chassis member that runs across the driver side. Jig needs to be attached to the chassis such that it can shear off the chassis member when the steering column collapses. |
| Centrelink/rack extension bearing mount | Henry Wu (??) | Two L shaped brackets going around the firewall chassis member; used to secure the linear bearings to the chassis. Where to mount, figure out shim dimensions. |
| Rack mounting | Requires coordinating with chassis to punch two holes through the chassis member behind the rack, will also require shims to attach rack to chassis. | |
| Steering wheel | Spec out steering wheel + quick release mechanism (~$40), the quick release mechanism from MSXII could possibly be reused. | |
| Ackermann geometry | ||
| Loading condition calculations/FEA | As per Jose; the current system is indeterminate. To do loading calcs, it will be best to assume a rigid suspension + break the force analysis down component by component. After this is done, components dimensions can be locked. | |
| Fastener selection | Currently, the CAD contains a variety of fasteners/threads of different sizes (imperial and metric) best to narrow these down to common sizes so assembly and repair can be done easier. |
