are those which turn, such as thos,
named, while dead axles are those useC
on double chain drive cars and do no
turn. The floating axle is one tina
does not carry any weight. 1t is USED
TO gain rotary motion only. The semi
floating axle, however, not only turns
the wheels, but takes some Of the
weight of the car. The difference be-
tween these two types Of axles Is In
the position Of the wheel bearings. In
the floating axle the wheel bearings
are outside Of the housing. The rear
wheels OF the car rest upon these bear
ings. 1t car be seen plainly that If
the wheels rest upon the bearings and
h bearings upon the housing the
housing must support the weight Of
the car. The end of the axle shaft has
some form Of jaw clutch which fits
into depressiOns in the wheel hub. In
the floating axle this connection be-
tween axle shaft and wheel is flexible.
but In the three-Quarter floating type
the end of the shaft is permanently
attached to tho wheel. being held usu-
ally by bolts.
In the semiloating type of rear axle
the bearing for the wheel instead Of
being outside the housing is inside.
The wheel Is placed on the axle and
held there by a key. Sometimes the
ends Of the axle shafts are square and
the inside of the wheel square so that
no Key Is necessary. With the wheels
on the axle shafts, nuts are screwed
on the ends Of the shafts to prevent
the wheel from backing of. The nuts
are locked with cotter pins.
