Steering:
World Solar Challenge 2017:
- 2.19.1 Steering must be controlled by a steering wheel designed so that it cannot catch on clothing while driving or when the driver exits the solar car.
- 2.19.2 Failure of any non-mechanical component of the steering system must not prevent effective steering of the solar car.
- 2.19.3 Steering shafts must be designed so that they will not spear the driver in a crash. A collapsible boss is an acceptable method to reduce steering wheel impacts.
Formula Grand Prix 2017 and American Solar Challenge 2016:
- 7.7.A Steering Wheel: All steering in the vehicle must be controlled by the driver with a steering wheel designed to have a continuous perimeter as outlined in Appendix A:
Appendix A:
- 7.7.B Steering Stops: The steering system must include steering stops to prevent dangerous or damaging steering travel. Steering stops cannot be held in place by friction. They must be welded, pinned or bolted in place, and placed in the steering system in way that will not create loads that will deform or scar the contacting pieces.
- 7.7.C Turning Radius: Solar cars must be able to make a U-turn in either direction, without backing up, such that any portion of the solar car that is within 200 mm of the ground remain within a 16 m wide lane. Portions of the solar car above 200 mm above ground may exceed the 16 m distance.
- 7.7.D Steering Backlash: The steering system must be designed with sufficient strength/stiffness and have minimal backlash so that the driver can always maintain good directional control of the vehicle.
