The transmission unit of the vehicle is one of its most important parts; without it, we cannot move the car by giving it engine power. A translation unit is used to move each vehicle. Be it manual transmission or automatic transmission. Through this article, we will get detailed information about the transmission of the vehicle.
What Is A Transmission?
Transmission is one of the important parts to make the vehicle move, which is a mechanical box made of a mixture of iron + aluminum.
Inside, the transmission mechanism system is fitted with the help of nut bolts. To make the vehicle move, the transmission itself transmits the main power of the engine to the wheels of the vehicle, due to which the vehicle moves without any jerks.
And it is applied according to the need. Because the power of the engine of any vehicle cannot be given directly to the wheels of the vehicle, the power is given to the vehicle through the transmission unit as per the situation and requirement. And the power and speed of the vehicle are controlled by the transmission unit itself.
The transmission system itself adjusts the gear ratio between the drive wheels and the engine. The speed of the vehicle is slowed down or accelerated by the transmission gears themselves.
When the transmission disconnects the engine from the drive wheels to stop a vehicle, so that the engine can remain idle when the wheels are not in motion, the transmission system itself enables the engine to run more slowly while the vehicle is driving at a constant speed.
How Does A Transmission Work ?
Transmission is a bunch of different-sized gear selectors. which the toothed gears determined according to the engine power and speed of the vehicle are connected with the help of nut bolts, and the transmission has a main power shaft, which rotates continuously with the power of the engine through the clutch plate, when the driver operates the gear under the manual transmission.
So the power of the engine goes to the transmission through the clutch plate. And according to the gear assigned, the wheels of the vehicle get speed and power. by which the vehicle is moving and through the gear selector, the driver changes the gear based on the situation and speed.
Overall, a car transmission manages the power of the engine and transmits it to the wheels of the vehicle. by which the vehicle’s speed is constrained or reduced. And the vehicle is forced to pull the vehicle through the gear prescribed as per the requirement.
Main Types of Transmission
There are two types of main transmissions used in vehicles.
1. Manual Transmission 2. Automatic Transmission
Now we will know about both of these transmissions.
1. Manual Transmission
A manual transmission manages the power of an engine and transmits it to the wheels of the vehicle, which can be increased or decreased with the help of a gear selector according to the speed and requirements of the vehicle. A manual transmission cannot be operated without a clutch plate and pressure plate.
For this, a clutch is used for manual transmissions. In a manual transmission, the speed and power of the vehicle are managed through different-sized gear selectors. For manual transmissions, a clutch is a useful tool for changing gears, stopping and driving a vehicle. Without which the manual transmission cannot work.
Manual Transmission: Older model cars often have these. keeping still while the transmission is in neutral. The cluster gear and primary driving gear continue to rotate inside the transmission case.
Pressing the clutch pedal releases the shifter handle. Shifter handles move the forks and shift linkage, as well as slide a gear onto the main shaft. When the gears mesh, the clutch is released.
Constant-Mesh Transmission: Synchronized transmission is the term used to describe these transmission patterns. The main shaft gear, cluster gear, and driving gear are all constantly turning.
A sliding gear gearbox is employed to lock the gears into place. When necessary, a dog clutch aids in locking these gears into position.
The main shaft gear and dog clutch gear teeth lock onto each other and hold the gear in place. As the shift linkage moves, this happens. In this gearbox, synchronizers are employed to stop grinding or clashing when changing gears.
Pre-Selector Manual Transmission: A planetary gear system is used in the gearbox to preselect the gear ratio. The steering column’s tiny lever is used.
By depressing the foot pedal that signals one of the specified gears, drivers can change gears. As soon as the new gear engaged, the old gear disengaged.
2. Automatic Transmission
Semi Automatic Transmission: In semi transmission only clutch is automatic. But in a semi-automatic transmission, the driver has to shift the gear, and in this type of transmission, the driver does not need to disengage the clutch to shift gears, and semi automatic transmissions use a torque converter and a fluid flywheel, so that this transmission does not require a manual clutch for gear shifting.
Fully Automatic Transmission: In this type of system, the system of gear shift is automatic with a clutch. The gears keep shifting automatically according to the speed of the vehicle. In such transmission system or AP cyclic planetary type gear box is used. This type of transmission does not require a clutch or a change of gears.
Both types of transmission are connected to the engine of the vehicle. Be it manual transmission or automatic transmission. Only the clutch plate and pressure plate are mounted between the manual transmission and the engine, which transmits the power of the engine to the transmission.
