Transmission is the most
important part of any vehicle. It is the transmission or the gearbox that
provides the wheels with energy that is derived from the engine where the power
is generated.
Owing to this more often
than not, Transmission gears and shafts
are held responsible for the movement of your vehicle. No matter how advanced
and well maintained your car engine is if the transmission system isn’t in good
condition the car wouldn’t move at all. In essence, it would be safe to say
that without a proper transmission system moving the vehicle would be
impossible.
Parts
of transmission
There are certain types of transmission gears and shafts along
with other components in the transmission system and each one of them is equally
important and holds huge value in moving of the vehicle.
1. Gears
The drive gear located on
the output shaft determines in which gear your car is at the moment. The largest gear is the first gear and the smallest one is the fifth
gear. The largest one has the least spin, however; it brings the most usable
torque to the output shaft.
The idle gear is situated in
between reverse gear on the output shaft. This gear allows the vehicle to go in
the reverse direction. The gear shifter as the name suggests shifts the gear
when you move it.
2. Shafts
The input shaft is the
connector between the engine where the power is generated and the gearbox where
the energy is carried to from the engine. The layshaft or the countershaft is
what connects the input shaft with the output shaft. It also consists of drive
gears such as one used for reverse gear. The output shaft is the medium from
which the power is transmitted to the rest of the drivetrain.
Shift rod, shift fork,
clutch, collars, torque converter, oil pump, hydraulic system, valve body, and
many others when combined with transmission gears and shafts form a gearbox.
