Car Transmission system
manual transmission |
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.
