This is the first in a series of blog posts where we will provide updates towards the UC Davis Formula Racing Team’s progress. This post highlights the progress and achievements of Kyle Sager’s Wheel Package Sub Team. All information was gathered in a first-hand interview.
Wheel Package Revolutionized
This year, the Formula Racing Team is moving towards a
10-inch wheel package from a 13-inch. As a result, 3 things have improved
Can now achieve 30 degrees of steer. In
the past, the car couldn’t turn past 20 or 22 degrees, and with 30 degrees, the
car can actually make all the corners specified by the rules in the track.
Resulted in redesigns which allow for lighter
systems. The overall team had to adapt to the new wheel package with
several mechanical system redesigns, resulting in a vehicle that is 40 lbs lighter than previous years!
Better performance in handling. The
10-inch wheel package creates overall greater handling.
Using a 10-inch wheel package has caused pretty much every
mechanical system on the car to change:
The Suspension Sub Team, led by Colin Arnold,
has had to adapt with different styles of A-arms, different attachments of
A-arms, and different placements of A-arms.
The Chassis Sub Team, led by William Bowes, has had
to accommodate suspension and strengthen certain points in the overall chassis.
The Drivetrain Sub Team, led by Henry Lee, has
had to change the way they attach the axles and CV’s to the wheel package.
The Vehicle Dynamics Sub Team, led by Blake Christierson, has had to work extensively to verify that the 10-inch wheel is truly a better choice form a handling perspective.
The Electrical Sub Team, led by Evan Sousa and Brandon Collins, has had to add wheel speed sensors to adapt.
According to Kyle Sager, “it’s been an all around team effort to pull it together.”
Projects on the Wheel Package Sub Team
Of all the projects the Wheel Package Sub Team is working
on, Kyle Sager highlights the most interesting, which include the following:
Hubs – The hubs were machined down last quarter,
and they are now going to get hard anodized. Getting the hubs hard
anodized will allow for the aluminum centerlock nut to thread with the aluminum
hub without creating adverse friction coefficients.
Uprights – The uprights were only recently
machined by Optima Precison, and they are the main part of the wheel package,
holding it to the A-arms in place. This is a complex project, involving
five-axis machining, but Kyle Sager remarks that it was exciting to do.
Besides these projects, the Wheel Package Sub Team is working on wrapping everything together with smaller projects such as making rotors, hardening special studs to high yield strengths, etc.
have helped the Wheel Package Sub Team tremendously. Kyle Sager is immensely
grateful for the quality of the parts that he has been receiving, and the
ability to perform processes such as anodizing (processes that would not have
been possible with the resources that we have on our own). Sponsorships,
whether monetary, materials, machining, or processing have basically allowed
the project to occur. Without them, it would simply be impossible.
Specifically, the Wheel Package Sub Team would like to
extend their gratitude to the following sponsorships:
