how gearbox manual transmission work

 Car Transmission system

manual transmission

The transmission system is a mechanism that transmits power from the engine to the driving wheels. It transmits power and torque through the clutch, gear-box, propeller shaft, a differential. By gearbox, it gives four, five or six different ratios of torque output to torque input.

           

          

Gear Box regulates speed, torque and direction of the vehicle. Torque output will be the inverse of the speed of the vehicle. If the engine is directly coupled to the driving axle, the engine speed might be very low. At starting a vehicle needs more torque and less speed. If the driver increase speed it needs less torque. Gear Box provides this transition very smoothly.

  

It provides the necessary holding variation between the engine and the road wheels.
