Transmission design
As we all know automobile engine to a certain speed can be achieved under the
best conditions, when compared issued by the power, fuel economy is relatively good.
Therefore, we hope that the engine is always in the best of conditions to work under.
However,
the
use
of
motor
vehicles
need
to
have
different
speeds,
thus
creating
a
conflict. Transmission through this conflict to resolve.

twisting, twisting or slow down the growth rate by increasing torsional. Why can slow

also
by

For

Transmission speed gear based on the principle of variable twisted into various stalls

transmission structure, input shaft speed is the speed of the engine, the output shaft
speed is the intermediate shaft and output shaft gear meshing between different from
the

to the input shaft and output shaft to a circle.

When the growth rate of car drivers choose two stalls, Plectrum will be 1 / 2-file
synchronization and file a joint separation after 2 stall and lock the output shaft gear,
power transmission line similar, the difference is that the output shaft gear of a stall 2
stall replaced by the output shaft gear driven. 2 stall Biansuchilun typical transmission
ratio is 2.2:1, 2.2 laps to the input shaft and output shaft to a circle than a stall speed
increase, lower torque.

When refueling vehicle drivers growth stalls option 3, Plectrum to 1 / 2 back to

When car drivers Option 4 refueling growth stalls, Plectrum will be 3 / 4 from

When the car to accelerate to more than car drivers with the choice of five stalls,

Ride from the driver of the considerations, better transmission stall, stall adjacent
stall more than the transmission changes the ratio of small, and easy to shift smoothly.
However, the short comings of the stalls is more transmission structure is complicated,
bulky, light vehicle transmission is generally 4-5 stalls. At the same time, transmission
ratio is not integral, but with all of the decimal point, it is because of the gear teeth
meshing is not caused by the whole multiples of two gear teeth can lead to the whole
multiples of two meshing gears of uneven wear, making the tooth surface quality have
a greater difference.

Manual transmission and synchronizer
Manual transmission is the most common transmission, or MT. Its basic structure

up
in
one

is
a
two-axle
shaft,
where
input

the

and
intermediate shaft, which constitute the main body of the transmission and, of course,
a Daodang axis. Manual transmission known as manual gear transmission, which can

The first axis of the intermediate shaft and gears meshing gears often, as long as the

At present Synchronous Transmission is based on the synchronization of inertia,
mainly from joint sets, synchronous lock ring, and so on, it is characterized by friction
