Figure 1: Steering Rack Sub Assembly
This assembly was originally a stock Prowerks Aluminum Steering Rack altered by Carnegie Mellon's Formula Society of Automotive Engineers to better fit an FSAE race car. We then disassembled their altered steering rack into its individual components and sub-assembilies. The components, and some basic information about each one, are listed below.
Part No. | Part | Qty. | Wt. (g) | Function | Manuf. Proc. | Material | Picture
|
001
| Pinch Gaurd | 2 | 64 | Protects Pinch Points | Extruded, Welded, and Milled | Aluminum |
|
002
| Clevis | 2 | 33 | Connects steering rack to tie rods | Milled | 6061 Aluminum |
|
003
| 5/16-24 Bolt | 2 | 13 | Bolts clevis to steering rack | Forged | Steel |
|
004
| Pinion | 1 | 99 | Convert rotational motion to translational motion | Machined | Steel |
|
005
| Rack | 1 | 167 | Works with pinion to convert motion. Connects left and right toe links | Machined | Aluminum |
|
006
| Extension | 2 | ~71 | Extend rack to reach tie rods | Extruded and Lathed | Aluminum |
|
007
| Set Screw | 1 | <1 | Retains primary bushing | Tapped | Steel |
|
Sub-Assemblies*
|
001
| Retaining Block/Mounting Block | 1 | 189 | Retains primary bushing | CNCed | Aluminum |
|
002
| Pinion Bushing | 1 | 21 | Smooths pinion rotation | Machined, Extruded, and Assembled | Aluminum, Bronze, Rubber, and Steel |
|
` *Sub-Assembilies were not deconstructed further. It was decided that doing so would result in the destruction of some components with little or no knowledge gained.
