Shaky Beginnings
The Electric Vehicle Research Project began as a gleam in the eyes of
several Mechanical Engineering students and Dr. Dale Anderson and Dr. Jim Lowther.
The team of students included a certified auto body repairman and several novice dirt
trackers. The gleam in the team's eyes soon manifested itself in the physical form
of a wrecked Volkswagen Rabbit. Exhibiting rare, almost maniacal vision, the team
saw the wrecked Rabbit as the winning entry in the Sunday Challenge at the Atlanta
Speedway in Atlanta, Georgia.
In short order the body man had the side swiped car in roadworthy
condition with a gleaming white paint job. Rewarding the efforts of the faculty on
the team, General Electric donated an experimental 19 horsepower DC motor and controller.
It is at this point that the real engineering started with the problem solving
flare characteristic of dirt trackers.
Several problems had to be overcome before the Rabbit could be a true
"automobile:" the motor had to be coupled to the transmission and the batteries
had to be accommodated. And these are just the big problems.
Many schools and businesses that had entries in the Sunday Challenge
contracted out the dirty work that the guys from Louisiana Tech did for themselves.
Dirty work such as the body restoration and painting, motor to transmission coupling, and
battery installation.
Batteries were donated by Trojan. Huge batteries. The weight
of the batteries all by themselves exceeded the gross vehicle weight of the Rabbit.
Undaunted, the Louisiana Tech team replaced the axle under the rear of the car. You
can see the big meaty axle under the car in the second picture on The Rabbit Page. The team would be able to make the first
competition. Or so they thought.
Of course, batteries alone wouldn't make the car move; the motor had to be
coupled to the transmission. This was a very interesting problem that required a fast
fix because the date of the competition was looming. Being a front wheel drive
vehicle, there was no room for a direct coupling of the motor to the transmission.
The 19 horsepower motor is small but not that small. It is at this point
that the dirt tracker experience really paid off.
Why not use a supercharger belt? Believe it. Those guys
coupled the motor to the transmission with a belt! Yet another problem arose out of
using a belt. Or at least out of the belt that they had purchased. The belt
was too long. The day of the competition loomed ever nearer. What to do!
What to do? An idler pulley. They simply intended to use an idler pulley to
tension the belt. It decreased the wrap of the belt on the driven and driving
pulleys but it would do the trick. But....
You guessed it. Yet another difficulty. The belt was so long
there was, in the belt path they had chosen, no place to put the tensioner to tension the
belt. Lack of sleep, surely, resulted in their solution: cut the Rabbit's front
crossmember to accommodate the idler pulley. And so, the Rabbit was made ready for
the first competition just in the nick of time.
A Day At the Races
Even getting to the races the team demonstrated the ingenuity
characteristic of Tech graduates. Using a rental truck to transport the Rabbit to
Atlanta left the team with no easy way to load the car. Planks were out of the
question because of the excessive weight of the car. There were no convenient
embankments to back the truck up to. Except one. A dung heap. With the
sweet smell of cow manure in their nostrils and green stains on the soles of their shoes,
the team was off to the races.
With competing teams that couldn't even figure out how to charge the
batteries in cars built by contractors, the Louisiana Tech team easily won first place in
the engineering portion of the judging. The Tech team not only knew their vehicle,
they had numbers to back up the design. It was a very good show and a great
statement for the quality of Tech's engineering students.
The real upset came with the performance competition. In a fit of
democratic spirit, the team drew straws to choose the car's driver. No problem.
The guy who drew the shortest straw hopped into the Rabbit and took off.
A very strong start. Things looked great with the car in first gear.
The other team members could be seen unconsciously shifting phantom gears at the right
time. Unfortunately, the guy in the car had never driven a stick shift! Once
around the track in first. Once again around the track in first. You get the
picture.
Fortunately, the performance competition included endurance. Many
cars were unable to make all the laps. In first gear the Rabbit had no problem.
When all the points were added up the team and the Rabbit won fourth place.
However, since the front crossmember was cut, the Rabbit started sagging.
Today, the front wheels sit still, gripping the ground trying to keep the Rabbit's
belly from dragging. The Atlanta race is the only competition that the Rabbit every
participated in.
The year of the Atlanta competition was the last for the Mechanical
Engineering students on the team. They've all graduated and gotten jobs. Only
one student remains from the days of yore: the Electrical Engineering student who joined
the team to install the motor controller, Glenn Moffett. With the feel of the thrill
of competition wafting through his mind, he joined Dr. Roots and Dr. Cox in the Electrical
Engineering Department, along with Dr. Jim Lowther in the Mechanical Engineering
Department, on a quest for a newer, faster, better electric car.
Beginning the quest with a '64½ Mustang that Dr. Roots' son knew about,
they, along with James Weeks, the latest recruit, tried to decide if the rusted out old Mustang was
worth a shot. Infectious, that rare, certainly maniacal vision first exhibited by
the Rabbit team reared its ugly head again. "Give me a month and $2,000 and
I'll have this thing in great shape," James said. Dr. Roots and Glenn, the only
other people who went to see the Mustang, were hooked. James is not a certified auto
body repairman. And in short order that body repairman did not have the
Mustang in roadworthy condition.
In addition to Glenn and James, Scott & Joe (pictured here) and Sabrina worked
diligently for one full week to sandblast the shell of a Mustang.
Six months and one traumatic 36 hour work frenzy later, the Mustang looked
like this.
