Types of Transmissions Used in Car Vehicles – Functions of gears
called gear is used to regulate vehicle speed. "Not that
the speed of the vehicle which is regulated by the gas supplied? ". On the accelerator only regulates the engine RPM
indeed the engine speed will affect the speed of the car. However,
the torque generated cannot be changed. This is the reason there is
gear that works for
manipulate torque on the vehicle wheels by reducing the output produced at
machine. So even though the RPM generated on the engine is in the 2000s,
but the wheel rotation is very slow, even so
his strength is able to pull two vehicles behind him.
The functions of the transmission system include:
To enlarge the car's output torque
To regulate vehicle acceleration
To break the engine speed through the Neutral position.
To increase the engine output RPM.
In its development, this system is also divided into several types, namely:
Types of Transmission in
this trasmisis is an early type of a transmission system. Use
the working principle is quite simple, namely shifting gears (sliding) to
regulates the acceleration of output produced on the engine.
sliding transmission unit there are several components such as counter gear, and input gear
sliding gear. The input gear will rotate the counter gear permanently. For
inserting first gear must shift the sliding gear speed one so that it is linked
with the existing counter gear. Similarly, the gears
next speed when raising to tooth 2, 3 to 5 or 6 teeth.
Disadvantages of using
this system is a process that is not smooth and quite difficult. Because
in high rotation conditions linking two different spinning gears
that's difficult. So that this type is no longer used.
2. Type of Constant Mesh
Constanly type construction
mesh has similarities with sliding mesh, that's because
this type was created as an enhanced version of the sliding transmission type
Constant transmission type
mesh uses the linkage with a fixed gear (constant) between the counter gear and the output gear. However
The output gear can only be connected to the output shaft via a coupling
called "hub sleeve".
The workings of this transmission are, when the engine is running, the input shaft is
resulting from the machine will rotate the counter
gear. Meanwhile the counter gear is set so that it is connected to the output gear.
So every time the counter gear rotates, the output gear will always spin.
The amount of output gear depends on the number of transmission acceleration rates,
for a 4 speed transmission there are 4 output gears.
This output gear is floating with output shaft or not related
with output shaft. So that when the output gear rotates, the output shaft will not rotate. This condition is called Neutral position.
In the middle of the output gear there is a component called the hub sleeve. Unlike the output gear, the hub sleeve is related
with an output shaft and can move back and forth. So when the output shaft
rotating then the hub sleeve also rotates. The function of this component as a hook between the transmission output shaft with the output
In gear position 1, the hub sleeve 1 component will shift towards the output gear at speed 1. This hub sleeve will link the output gear rotation 1 with
output shaft so that the output shaft can rotate. For speed 2 then the hub
The sleeve only moves in another direction to connect to the other output gear wheels,
and so on when you want to change the level gear
that you want to use.
3. Type of Automatic Gear Shift
transmission which is often referred to as automatic transmission is basically not far away
different from the two types
It's just how the mechanism works and how it works
this type of transmission is very different. Transmission
matic uses the automatic gearshift method. So that it still exists
speed 1, 2, and so on it's just that the process of shifting takes place
which moves the transmission
namely the controller component. In this case TCM (Transmission
Control Module) which works through the solenoid lever as the actuator to help move
the teeth in their transmission. However, despite carrying the Automatic gear shifting, this type is also still equipped
with the transmission lever, the tusnya serves to position in the Neutral position,
Park, M, Driving
In position D or driving, the transmission system will work automatically.
But in M mode, you can move the transmission speed via the button
which is near the transmission lever. The difference with this type of manual car
no longer use the clutch pedal as a transfer condition
4. Type of CVT Transmission
this transmission goes into automatic transmission,
the difference with the types above, namely gearshift
take place variable. As the name implies, CVT transmission (Countinously
Variable Transmission) uses two gears with variable diameter ones
connected by a belt.
The gear is called driven gear and dive gear.
The diameters of the two gears are always opposite directions, that is
the diameter of the drive gear is small then the diameter of the driven gear is large, and this causes it
engine speed is reduced and the torque also increases. When
The diameter of the drive gear increases, so the diameter of the driven gear shrinks
resulting from a machine can be likened to an input from a machine.
The size of the second gear diameter is influenced by a force
centrifuges that apply according to the input speed. So that when the engine RPM
small, the moment generated is also large with a fairly large reduction level.
The higher the RPM produced from the engine, the level
reduction decreases and the output that results from transmission
Simple CVT transmission can be found on automatic motorcycles, there are also cars
using the CVT system. However, at
cars are usually given an additional system to be able to be positioned on
modes R, N and
3. Syncron Mesh Type
Synchronous mesh type, is a type of transmission that is often
used on manual vehicles today. That is because the transfer process
in gear type synchronous transmission mesh is smoother and lighter.
In principle, it works and construction is the same as the transmission type
constant mesh. It's just that there are additional components in the area "clutch hub"
component in the linkage between the output gear and hub sleeve.
This component is in the form of a ring syncronizer. This ring serves to equalize the rotation
between the hub sleeve and the output gear before they are connected. This copper ring has a tip
pointed that is intended so that the hub sleeve can be finely related to
The mechanism of this type is, when the hub sleeve moves toward the output
The gear will first connect to the syncrone ring, this ring will
equates the output gear rotation with the hub sleeve. So that's the hub sleeve
up to the output gear, it will be lighter when moving the transmission.
