V belt acts as a transmission belt that connects the pulley attached to it and transmits the force from the engine to the supplementary machinery which includes alternator, the hydraulic pump, and many other components.
The v belt pulley manufacturer makes the pulley attached with the v-belt for a particular purpose. The piston makes a movement whenever there is combustion of the fuel in a combustion engine. Pistons are connected to the rods and the movement of these pistons makes a crankshaft movement. The force from the rotation of the crankshaft makes the v-belt drive the v belt pulley also. So it is responsible for the high comfort during rides and also corrects operation of the engine.
The driver will have the feeling of comfort and safety as the ancillary components are in perfect working order. For instance, the pulley along with the v-belt is responsible for ensuring the operation of the air conditioning compressor so that it maintains the pleasant atmosphere inside the car. It also helps in the power steering assistance to the driver while driving. Electrical energy for the sparking and ignition of the engine or the ejection system is the work done by the v-belt. It also controls engine overheating by ensuring that the coolant circulates in the engine, preventing the worst situation.
Power cannot be supplied to the engine, or the engine might fail due to overheating as the water pump fails in such situation. Therefore torn v-belt is avoided as much as possible by the drivers. The main reason is friction that goes out of hand. So the replacement of belt at regular intervals as prescribed by the v-belt pulley manufacturer is a must.
