What does the transmission of a car do?
An automatic transmission is essentially an automatic gear shifter. Instead of manually shifting the gears with a clutch on a manual transmission car or a gear shifter on a bicycle, the automatic transmission does everything for you.
The rotary machine's output torque is increased by multiplying the torque by the gear ratio, less some efficiency losses. While in many applications gear reduction reduces speed and increases torque, in other applications gear reduction is used to increase speed and reduce torque.
- The first thing to know is what your transmission is. This is the part of the vehicle that connects to the back of the engine offering power from the engine to the wheels. The transmission uses the power created in the engine to keep the wheels spinning and keep the engine within a certain revolutions per minute range.
- Definition of reduction gear. : a combination of gears used to reduce the input speed (as of a marine turbine) to a lower output speed (as of a ship's propeller)
- The gear ratio is the ratio of the number of turns the output shaft makes when the input shaft turns once. A gearset with a 1-inch drive gear and a 2-inch driven gear has a gear ratio of 2:1. Through selection of the proper gear ratio, torque applied to the drive wheels can be multiplied.
Automatic transmission fluid (ATF), also known as transmission fluid or tranny fluid for short, is the fluid used in vehicles with self-shifting or automatic transmissions. It is typically coloured red or green to distinguish it from motor oil and other fluids in the vehicle.
- Radiator fluid is the antifreeze coolant that is used in your radiator to help cool your car engine. You should frequently check the levels of coolant in your car's radiator and cooling system and occasionally replace the radiator fluid in your vehicle.
- Flammability of automatic transmission fluid was demonstrated in the tests by spraying transmission fluid onto the steel tubing, heated to approximately 1,000°F. The transmission fluid immediately flashed. Both oils ignited easily on the 1,000°F tubing.
