the clutch teeth and cams of the spider and cam
assembly (1). Full engagement is assured by the
pressure of springs (3). When the spider is rotated
forward by the action of the ring gear, the clutch teeth
of the spider, now meshed with the clutch teeth of the
driven clutches, are held in a positive locked position
by the mating undercuts on the driving faces of all
clutch teeth. The assembly then rotates as a unit,
and each output shaft must turn at ring gear speed.
Refer to Fig. 3.
When the machine is driven in a straight rearward
direction, engagement of the clutch teeth is the same,
except the spider rotates in the reverse direction and
shifts and driving force to the opposite side of all
driving clutch teeth.
Right Hand Turn
When making a right-hand turn in a forward direction
under power, the driven clutch of the right-hand
clutch and ‘holdout’ ring assembly (2) remains fully
engaged with the spider clutch teeth and cams of the
centre cam. When the left-hand driven clutch and
‘holdout’ ring assembly (2) is required to rotate faster
to make the right turn through the over-running action
of the left wheel, it is free to ride up and over the
cams of the centre cam. Refer to Fig. 4. As the
‘holdout’ ring begins to rotate forward, the end of the
‘holdout’ ring slot engages the spider key, refer to
Figs. 5 & 6. On those NoSPIN® units using a
‘holdout’ ring with cams (see Fig. 5), this action sets
DESCRIPTION
The NoSPIN® element is an automatic locking device
which provides positive drive to both wheels. It
eliminates individual wheel spinning that is common
in conventional gear type differentials, while it allows
each drive wheel to revolve at a different speed when
the machine negotiates a turn, or is manoeuvred over
different road conditions.
This section covers the silent-type NoSPIN®
differential, which differs from the standard-type only
in the fact that either of the driven clutch and ‘holdout’
ring assemblies may overrun continuously when
required and then automatically return to full locked
engagement. The continuous over-running feature is
made possible by using ‘holdout’ rings as part of the
driven clutch assembly. During overrun operation of
the standard type NoSPIN® element, the driven
clutch will slide away from the spider and then back
into engagement after each tooth, causing a slight
indexing noise. As shown in Fig. 1 & 2, the NoSPIN®
element may use an external spring or an internal
spring, however, operation is the same.
OPERATION
Numbers in parentheses refer to Figs. 1 & 2.
Straight Forward
When the machine is driven in a straight forward
direction, the clutch teeth of both driven clutch and
‘holdout’ ring (2) assemblies are fully engaged with
