Certainly
the rear axle in the old wooden ox cart had only one job to do
in this type of vehicle the power was supplied from an outside force the
cart was either pulled or pushed while the axe or was stationary
and had nothing to do
but support the load with the coming of the automobile it became necessary
to transmit the power of the engine to the rear wheels so room was made for a
shaft to transmit this power next room had to be made
so that the differential ring gears and pinions could be inserted Of course
when this was done.
A strong connection had to be made to join the two tubes together
Chevrolet engineers build a strong candle leaver bread's across the cut in the axle
making it even stronger than the old solid axle the three units of the rear
axle housing the bridge
and the two tubes wire firmly assembled into one complete sturdy
unit Chevrolet engineers realized
that this part of the axle should be easily accessible from the outside.
So an inspection plate was placed over the rear of this banjo construction.
The rear axle own knowledge became merely an axle housing.
To support the load.
Next years were added to transmit the engine power to the axle shafts
and wheels.
All these axle shaft have to do is turn the wheels they do not bear the weight of
the load as it is borne by this husky axle housing.
One of the outstanding features of Chevrolet's new full floating rear
axle is the barrel shaped roller bearings which are entirely
self-reliant. Because of the barrel shape of these rollers.
They form only a small area of contact with the races.
Under normal load conditions reducing friction to a minimum.
And keeping the rollers in exact alignment as the load is increased
each roller spreads into the very race providing support along the width of the
very. When the load is decreased.
Again the area of contact is decreased so that the capacity of the Barry.
Is always in proportion to the load this feature prevents the races
from becoming grooves.
As is common in straight roller bearings and the very My.
Is therefore greatly increased in order to show you the action of these bearings.
This drawing has been greatly exaggerated. Another important advantage.
I was Chevrolets full floating rear axle is the four pinion
differential modeling.
This means that any load IA spread over forty.
Instead of only two and insures less strain on all parts
and longer axle life.
In addition there are axle housing on the nineteen thirty six Chevrolet truck is
thirty five percent stronger than last year's housing in fact
this housing alone is stronger than the combined strength of the housing
and shaft.
In previous models this new heavier than a huskier rear axle
housing with inspection plate together with the new exclusive self aligning
bearings combine to make this full floating rear axle the finest axle
ever built into a truck.
With this construction axle shaft brake gauge is extremely remote
but should it ever happen
that Cheryl a full floating rear axle permits easy removal
and replacement of either axle shafts without taking off the wheel
or removing the loads the design of the axle with a smaller Banjo Center
gives it much greater road clearance. What's yours.
Another advantage
that helped to make this new axle the outstanding development in the nineteen
thirty six Chevrolet truck.
