What is car transmission?

Question

That is my assignment in physics

Answer 1

A transmissiom transmits mechanical power from a prime mover—such as an engine or electric motor—to some form of useful output device, normally rotary in form, and generally at a reduced rate of angular speed but at a higher motive torque.

Generally, transmissions will provide a significant speed-power conversion known as gear reduction (in speed) to a higher torque (rotational force or power). In motor vehicle transportation, a vehicle transmission may provide many different speed-power ratios known colloquially as "gears" or "speeds", and possibly several variant speeds in reverse direction as well—Tractors and large trucks especially may have a dozen or more forward "gears" which vary from a crawling speed at high torque to high speed at low torque where the only torque needed with a load coasting along at a given speed are that small additional energy (force) needed to overcome ongoing friction and other road losses such as climbing a grade. When the torque needed to surmount a grade is insufficient at a higher rotational speed, the gearbox is shifted into a lower gear to provide more power, as was needed when initially accelerating said vehicle to the desired road speed. Gearing has much in common with the mechanics and mechanical factors present in pulley systems. One trades distance (numbers of rotations) for increased force.

Answer 2

the transmission is what takes the power from the motor through the flywheel and uses it to spin a driveshaft. The driveshaft then spins gears in the differential which rotate axles and make the wheels spin. The transmission contains drive gears that spin at the same speed as the flywheel. Shifting to a larger diameter gear allows for higher speeds through the driveshaft and ultimately through the rear wheels.
