GEARBOX
*Gearbox is a speed and torque changing device. It changes speed and torque between the engine and driving wheels.
*An automobile requires high torque when climbing hills and when starting, even though they are performed at low speeds. On other hand, when running at high speeds on level roads, high torque is not required because of momentum. So requirement of a device is occur, which can change the vehicle’s torque and its speed according to road condition (or) when the driver need. This device is known as transmission box (Gearbox).
FUNCTIONS
1. Provide the torque needed to move the vehicle under a variety of road and load conditions. It does this by changing the gear ratio between the engine crankshaft and vehicle drive wheels.
2. Be shifted into reverse so the vehicle can move backward.
3. Be shifted into neutral for starting the engine.
​
4.It helps the running engine to be connected to the driving wheel smoothly and without stock.
