How do car gears operate?

While driving to work today I became curious as to how the gears in a car actually work. Why does the car go faster by changing gears and what actually happens when changing from one gear to the next?How do car gears operate?
Your transmisson has multiple gears that vary in diameter. They can connect to the main drive or power gear as needed.



The size of the gear affects how quickly the it turns in relation to the drive gear.



To get the car moving, it takes a great deal of force, so the gear is large and it turns slowly in relation to the drive gear giving power vs speed.



As the car gains speed, the transmission changes to a smaller one, which turns faster relative to the drive gear.



Finally when you are at cruisng speed the smallest gear engages turning at nearly the same speed as the drive gear.



If you go up a hill and the effort needed by the motor is increased, then the smallest gear dis-engages and the transmission downshifts to a larger gear - giving the power to lift the car up the hill.



If you want to see this in action, look at a 12 speed-bike. As the chain moves from larger to smaller gears, the effort need to turn the wheel changes.



If you ride with someone who uses a manual transmission, they listen the strain on the engine to decide when to shift from one gear to another.How do car gears operate?
Automobile transmission are very complex machinery and explaining it will require a lot of pages. To explain it to you in a nutshell, when you shift gears in a manual transmission vehicle, the gear stick is connected to a whats called ';gear fork'; which basically moves a primary gear around other already moving gears caused by the combustion from the motor. These gears that are already moving is the gears for your 1st, 2nd, 3rd, 4th, 5th drive speed. The primary gear basically detaches everytime you shift onto another gear. Think of it as a bicycle, it has the same principle but as I said before.. way more complex.
Through a process known as ';torque multiplication';. The product of each gear ratio, along with that of the differential (or final-drive) gear, determines how much torque is delivered to the drive wheels. Starting from a dead-stop requires a much greater torque value than that required to keep the vehicle moving, so the ratio gradually decreases with the selection of higher gears.
Stay blond dear i fear the answers to this question will be beyond your comprehension.
similar to gears on a push bike.
