FUNCTION OF GEARBOX : 

FUNCTION OF GEARBOX An I.C engine generating power is not sufficient to move the vehicle ,therefore gearbox is use increase speed of vehicle. Gearbox is used to obtained the various fixed torque ratio according to requirement. It also help to reverse the vehicle since engine can run in one direction. A high torque is require to run the vehicle from during climbing a hill which required high engine speed. Keep the vehicle in neutral position, without stopping the engine.

HOW TO WORK? : 

HOW TO WORK? A gearbox is a method of transmitting energy from one mechanical device to another. It works by increasing the torque while at the same time reducing the speed. Torque generates power by twisting and bending solid material. The gearbox is located in the power shaft, and every gear in the gearbox has a specific purpose in the operation of the vehicle. Each level of speed has a relative gear that gives your vehicle the right amount of speed and torque. A gear ratio is used to determine the level of force in each gear, and once this ratio is set, it cannot be changed.

PowerPoint Presentation: 

OPERATION MANUAL; A manual gearbox works when the clutch is pressed down. This allows the gearshift to be put into any desired gear. Most manual transmissions have five or six gears in their gear box. When the gears in the gearbox are shifted into a higher gear, the gearbox gives the vehicle more power while using less fuel. This works because the gearbox rotates the drive shaft, alternating the torque and power. When the gears are shifted into a lower gear, your vehicle will run at a lower speed. Gears engage the drive shaft at different points along the way. When the gear is lower, it will engage the drive shaft closer to the gearbox. 2. Automatic An automatic transmission's gearbox works in concert with the accelerator, brakes and drive shaft. The transmission in an automatic vehicle is more expensive and can be more difficult to maintain and replace. Automatic transmissions use the programmed gear ratio, and spin the drive shaft according to how much power is coming from the accelerator. When the brake in the vehicle is applied, the gearbox decreases the speed by using counterweights to slow the drive shaft.

TYPE OF GEAR BOX : 

TYPE OF GEAR BOX A)Selective gear transmission Sliding mesh type Constant mesh type 3) Synchromesh type a)Three speed gear box b)Four speed gear box C)Six speed gear box. 4)Planetary gear box.
