Dog Box Transmission on Toyota VITZ Super 1500 - SEPANG INTERNATIONAL
H.Drive Racing Dog Box Transmissions
Dog engagement is normally used in racing applications where fast, precise
shifting is needed. 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. Ideal gear
selection—e.g. minimal clashing and wear of the dog rings—is achieved
by quick shifts; the motto here is "the quicker the better", so bang away.
There is no depressing the clutch in the conventional sense like with the
synchromesh transmission. A momentary break in engine load until the shift
is achieved by a quick throttle blip or clutch depression. The driver will
then experience the dog ring engaging with the next gear and the throttle
can be reapplied. With practice this can be done in milliseconds. In fact,
a driver can preload the stick shift in the direction of the next shift,
and then when he either blips the throttle or clutch the shifter will
quickly click in the desired gear.
With all else equal, dog-engagement gears are much stronger than
synchro-engagement gears because without needing to make space for synchro
rings, the gears themselves can be made thicker. The number of dogs (teeth)
and the size of the openings determine the window of opportunity that the
dogs have to engage during the shift event. Rings with a smaller number of
teeth provide a more efficient, smoother shift quality. The downsides to
this easier engagement are increased noise and abruptness on the shift.
