Driveline -
more than just a tube with uni joints on the end!
Universal
joint failures and wear - Brinelling is the
wearing of the universal cross journal; causes:
lack of lubricant
Contamination
Overloading or just
plain old age !
Tubing Failures:
At right:
In this case a truck shaft
had been re-tubed using ordinary water pipe which is far
too brittle to be used on a driveline and extremely
dangerous - luckily no one was hurt when this large
shaft tube failed. The correct tubes below did what they
were designed to do; when overloaded they just
fold up!
Many driveshafts and components suffer premature
failure, sometimes the results are spectacular
owing to the speed attained by an operating tail shaft.
Here are some failures of shafts that have been bought
in to SDS for repair.
Slip yokes at
right:
Compare the factory USA Spicer slip yoke on the left
with the welded 'custom' made one on the right. It
just does not pay to go the 'cheap' option when you are
talking about high horsepower vehicles. In the end
it will cost more. The slip yoke at right failed
at high speed taking the trans. output shaft with it
including most of the transmission internal gears -
ouch $$$$$$ !
This Sports Sedan puts
its power to the back wheels
through a custom kevlar wrapped alloy driveshaft (below)
manufactured and designed specifically for racing by SDS
at our factory at Greenacre - high performance built in!
Automotive Slip
Yoke
failure: This back
yard manufactured slip yoke met a predictable end, and
took out the transmission in the process. Picture
at right and below.
What sort of
universal is that? Pictured below is a
Thompson Coupling being balanced and tested for
performance on Sydney Driveline's 'AXILINE' Balancer.
The Thompson Coupling, invented and manufactured
in Australia by Glen Thompson is the world's only
friction - less universal and can operate at
uneven angles without inducing any vibration. An
amazing Australian invention.
