The function of belts in an automobile is to connect and drive two shafts to the motion of a rotary. This is done by using a series of pulleys. The motion of the rotary is where or how the engine gets its power to various accessories that are mounted to the engine. These accessories are vital to the operation of the vehicle like pumps, exhaust fans and air compressors.
Types of belts:
V-belts are designed to provide high-traction power and to fit into a V shaped groove. The Poly-V belt is also designed to provide a high-traction form of power, but is flat on the outside with multiple V-shaped grooves on the inside. A drive belt that is similar to these V-belts but are open-ended belts that do not require meal clamps are called V-Link belts. Using a V-Link is a last resort for when other belts will not reach or fit as they are quite costly and will only carry a small load.
Belts that are lighter in weight and can function at high speeds are called Flat belts. There is little traction with these belts so they do tend to slip. The Timing belt is one of the most important belts and is quite different to other types. It does not require friction to function, nor does it it have teeth. In contrast with other belts, the Timing belt has a small capacity for power.
The function of drive belts:
Drive belts are simply used to drive components of the vehicle. Even though these belts are very inexpensive, they have the ability to put a stop to a functioning vehicle if they break. Without the belt to drive the vehicle component, there can be no motion or function from that component. For example, the water pump functions through the use of a drive belt. This pump is used to circulate water through the vehicle’s system thereby keeping it cool. Should the belt break and the water pump fail, water ceases to circulate through the system and the engine quickly overheats. Although a broken drive belt is a large problem, a broken serpentine belt can be an even larger one. The serpentine belt drives multiple components at once, so if this belt breaks then multiple functions are compromised.
What causes a belt to break?
Drive belts are made of inexpensive rubber. Over time, belts suffer normal wear and tear and this can cause them to dry out or crack. The belt will break as wear and tear compromises the integrity of the belt.
Is it difficult to replace a drive belt?
Depending on the location of the belt and your mechanical aptitude, it may be a simple process to replace a drive belt. A serpentine belt can be pretty complicated so it is probably best left to the professional mechanic. Most professional mechanics recommend that the serpentine belt be changed every thirty-five thousand miles. These belts can last up to sixty thousand miles as can the timing belts.
