How Auto Transmission Works Explained In Great Details

Auto transmission also known as automatic transmission or automatic gearbox, is that kind of vehicle transmission used in automobiles. In the recent years, gears of vehicle are changed automatically as the vehicle moves forward. With the invention of this technology, you no longer have to change the gears manually while driving.

History

Alfred Horner Munro a steam engineer of Canadian origin is credited to have invented the automatic transmission in the year 1921. The earliest automatic transmission made use of compressed air instead of the hydraulic liquid for its operation. As a result of using only compressed air the automatic transmission was not very powerful and due to the very little amount of power it produced, the prototype did not receive much recognition and was a commercial failure. The use of hydraulic fluid to power the automatic transmission was first done by two Brazilian engineers in the year 1932. The technology of automatic transmission was used by companies to power the tanks during the world wars to great effect.

Working Of Auto Transmission Vehicles:

Different vehicles have different values till the gear is automatically changed. The parking pawl feature present in most vehicles of today, can be used by you to lock the transmission shaft, preventing the rolling of the vehicle either in the forward or the backward direction. The large vehicles that are used for construction purposes such as a forklift or a lawn mower have a limited speed range, a device converting torque provides for the variation or change of gears in these vehicles.

Different types of auto transmission:

The way in which technology progresses in today’s world, new discoveries and improvements in all sectors of life is being made every day. The sector of auto transmission of vehicles is not far behind too. Within a few years of its inception the automatic transmission is having its varieties too. As of today, continuously variable transmission and semi-automatic transmission are the two variations of transmission present in the vehicles.

Auto Transmission

The transmission box’s computer can be used by you to change the gears of the car. A traditional automatic transmission makes use of a torque convertor to change the gears; the number of gear ratios that can be obtained with this is finite in number. A continuously variable transmission makes use of a belt system to change the gears and the gear ratio obtained is infinite. A semi-automatic transmission functions like a manual transmission but the clutch present in it is controlled by electro hydraulic means.

The traditional automatic transmission is the basic mode of transmission, available in today’s cars. The option for you to change the engine type to continuously variable transmission as well as semi-automatic transmission is also present in today’s cars.

Different modes

The auto transmission present in a vehicle comes in various modes. The parking mode of the automatic transmission locks the transmission and aids you in parking the vehicle. The reverse gear of automatic transmission permits the vehicle to be driven backwards by you. The neutral gear literally cuts off all the effects of gears on the vehicle and the vehicle is allowed to move forward under the effect of its own momentum.

The drive gear, which is the latest addition to the different modes available in automatic transmission, makes all the available gears which can be used for driving functional and allows quick switching of the gears. The first gear, the second gears are the different modes to which the automatic transmission can be changed to. The sport gear can be termed as the augmented version of the drive gear, using this mode you can accelerate the vehicle really fast. The brake mode and the winter mode are the latest additions to the different automatic transmission modes.
