Dog clutches are used inside manual automotive transmissions
to lock different gears to the rotating input and output shafts
. A synchromesh arrangement ensures smooth engagement by matching the shaft speeds before the dog clutch is allowed to engage. Dog clutches are commonly used in racecars.
Is dog clutch positive?
.
Positive Clutch (or) Dog and Spline Clutch
consists of a sliding sleeve fitted with the driving member having two sets of internal splines
. external dog clutch teeth on the riving shaft. with the dog clutch teeth of the driven shaft. Thus, the sleeve turns the splined shaft with the driven shaft.

Why positive clutch is used?
The positive clutches are used
when positive (no slip) drives are required
. These clutches transmit power from the drive shaft to the driven shaft by the interlocking of jaws or teeth. They are rarely used as compared to friction clutch. E.g. jaw clutch, claw clutch, toothed clutch.
What causes clutch noise?
Causes of clutch noise
Whistling or whining from the clutch can be caused e.g. by the
release bearing running off-center, an off-center input shaft, or a defective pilot bearing
. On the other hand, rattling noises may be due to load alterations if clutch disks are furnished with preliminary dampers.
What are dog gears?
Dog gear engagement is
facilitated by numerous large teeth (dogs) that mate into matching openings machined into the opposite surface of the drive gear
. Unlike the synchro engagement, there is no synchronizing mechanism to assist in equalizing speed.
Where is the dog clutch located?
When it is engaged, the front wheels also have driving torque from the engine through the dog clutch which is positioned inside the transfer case. The location of the transfer case is
between the transmission and the rear differential
, see figure 2.
What is synchromesh?
The job of the synchromesh is to
synchronize the rotational speeds of the gear and main shaft before locking them together
. Friction from the contact of the cones synchronizes their speed and the dog teeth slide into a mesh to lock the gear and shaft.
What’s the difference between dog clutch and soft clutch?
Dog Clutch – two mechanical gears that mesh together with a swift pull of a lever usually floor mounted
