What is Gearbox Or Transmission? Use of transmission in a vehicle.

What is Gearbox:

Gearbox could be a machine in the power transmission system, that provides the controlled application of the facility. usually, the term transmission refers merely to the gearbox that uses gears and kit trains to supply speed and torsion conversions from a rotating power supply to a different device.

Introduction To Gearbox

The word “transmission” is used for a device located between the clutch and the propeller shaft. It may be a torque converter, gearbox, overdrive, or hydraulic drive, or fluid drive.
In British English, the term transmission refers to the entire drivetrain, together with the clutch, gearbox, prop shaft (for rear-wheel drive), differential, and final drive shafts. In English, however, the term refers additionally specifically to the gearbox alone, and elaborate usage differs.

The most common use is in motorcars, wherever the transmission adapts the output of the inner combustion engine to the drive wheels. Such engines have to be compelled to operate at a comparatively high move speed, that is inappropriate for beginning, stopping, and slower travel. The transmission reduces the upper engine speed to the slower wheel speed, increasing torsion within the method. Transmissions also are used on pedal bicycles, fastened machines, and wherever totally different move speeds and torques area unit custom-made.
Often, a transmission has multiple gear ratios (or merely “gears”) with the flexibility to modify between them as speed varies. This change is also done manually (by the operator) or mechanically. Directional (forward and reverse) management may be provided. Single-ratio transmissions additionally exist, that merely amendment the speed and torsion (and typically direction) of motor output.
In motorcars, the transmission is connected to the engine shaft via a regulator or clutch or fluid coupling, partially as a result of combustion engines cannot run below a selected speed. The output of the transmission is transmitted via the shaft to 1 or additional differentials, that drives the wheels. whereas a differential may offer gear reduction, its primary purpose is to allow the wheels at either finish of associate degree shaft to rotate at totally different speeds (essential to avoid wheel slippage on turns) because it changes the direction of rotation.


Conventional gear/belt transmissions don’t seem to be the sole mechanism for speed/torque adaptation. different mechanisms embrace torsion converters and power transformation (e.g. diesel locomotive transmission and hydraulic drive system). Hybrid configurations additionally exist. Automatic transmissions use a valve body to shift gears mistreatment fluid pressures in response to hurry and throttle input.

TYPES OF TRANSMISSION

The transmission is classified as follows:

  1. Manually operated selective transmission. This type used in cars, buses, and trucks. It is also known as standard or stick shift. It is of three types: constant mesh, sliding mesh, and synchromesh.
  2. Overdrive. A semi-automatic type used in conjunction with a selective transmission.
  3. Chrysler semi-automatic transmission. An electric and hydraulic controlled type used in conjunction with a fluid drive or a torque converter.
  4. Automatic transmission. (a) Hydromatic drive. (b) Torque converter transmission.
