N O S P I N D I F F E R E N T I A L G R O UP
The driven clutch for the outside wheel can not be
engaged with the spider until the speed of the outside
wheel becomes slower and equal to the speed of the
bevel gear. The holdout ring keeps the driven clutch
and cam from being engaged with the spider and
center cam until the machine moves in a straight
direction. At this time the operation of the differential is
the same as STRAIGHT FORWARD OPERATION.
Forward Turn With No Power
The operation of the NoSpin differential is the
same as for FORWARD TURN WITH POWER.
The outside wheel is still made to turn faster (by the
traction of the road) than the speed of the bevel gear.
The inside wheel is turned at the speed of the bevel
gear.
S Y S T E M S O P E R A T I O N
The action of the differential is the same as it is in
the STRAIGHT FORWARD DIRECTION.
Reverse Turn With Power
The action of the differential is the same as it is in
the FORWARD TURN WITH POWER condition
except spider (17) turns in the opposite direction.
Straight Reverse Operation
When the machine moves in a straight reverse
direction, teeth (22) on both sides of spider (17) are
fully engaged with teeth (23) of driven clutches (6)
and (11). Spider (17) turns in the opposite direction
than it turns in straight forward. Since the spider
turns in an opposite direction, teeth (22) of the spider
push against the opposite face of teeth (23) of the
driven clutches.
