❓ Problem statement
U-Joint setup is required to be past the 45 degrees possible for the current U Joints. Additionally, the U-Joints are two different angles => decreasing the power transmission from the steering to the rack
💡 Research insights
📊 Solution hypothesis
🌈 Design options
Steering rack NEEDS to be extended to reduce the length of the tie rods
How are we going to positively lock the steering extender (since the rack has a blind hole)
Bolt the clevis into the steering extender (need to safety wire the bolt onto the clevis) and have the adjustable tie rod with heim joints and jam nuts at both ends
Include linear bearings mounted to the frame tubes for support at both ends and implement steering stop at ends of the extenders (as a step in the shaft) to make contact with linear bearing housings at full turn
Output Shaft to Coupler | Option 1 | Option 2 | Option 3 | |
---|---|---|---|---|
Overview | Use a 5/8” OD shaft with a through hole to fix inside of splined coupler | Use a 5/8” OD steel shaft and weld onto the coupler | Use a greater diameter shaft | |

Benefits and risks | simplest solution Need extra support which will need additional mounting tabs on frame | increase legroom for driver (makes egress easier), eliminates need for joints and gears alters steering geometry by increasing bump steer necessitates new steering arm to protrude above and to the side of upright | reduces angle needed for both u joints/eliminates need for two u joints bevel gear can be tricky to keep meshing bevel gear with correct dimensions may be difficult to obtain | |
