Learn About Transmission Belt Types and The Differences

 Based on its configuration, an engine can be categorized. The primary timing belt, the belt that powers the oil pump, and accessory belts are just a few examples of the various belt kinds that are available. With the development of automobiles and their present capabilities, accessory belts or auxiliary drive belts have gained more significance. In reality, the relevance of FEAD (Front End Auxiliary Drive) systems has expanded dramatically in relation to propulsion, necessitating higher power capacity with less space and fewer cylinders.

Auxiliary belts' function has emerged in this situation, significantly changing through time in terms of both design and materials. Increasingly longer auxiliary belts and stronger materials are a few adjustments that were made. In this article, we discuss the main varieties of transmission belts that are kept within the car as well as the unique characteristics of each.

Types Of Transmission Belts And Their Application

According to their intended use, transmission belts may be divided into many varieties and are often constructed of rubber. A drive pulley delivers power to accessories through the auxiliary drive system. There is the traditional system, which uses several belts to power various equipment such as the alternator and power steering pump. Nevertheless, serpentine belt systems that are capable of powering all the accessories on their own are also frequently seen in systems. While it is true that some engines have belts with teeth or that are synchronized, such as timing belts, that drive an accessory, the two most typical forms of auxiliary drive belts are as follows:  

V-belt

The so-called secondary or auxiliary accessories are driven by the V-belt, which has an isosceles trapezoid-shaped cross-section. This system used to trigger components like the electric generator and water pump, but more recent additions include the power steering pump and air conditioning compressor. These belts worked by concentrating on the pulley groove to address alignment and twisting issues. Furthermore, due to their design, which is essentially a wedge, they possessed a far better grip than the supplementary belts of the past.

These belts typically only drive one periphery at a time and are distinguished by being thinner and smaller. So, it's extremely normal to discover more than one V-belt yet just one serpentine belt on an engine. The ribbed or poly-V belt has largely taken the place of this type of auxiliary belt in current applications.

Poly V-belt

The poly-V belt, often referred to as an auxiliary ribbed belt, a poly belt, or a poly-v belt, is a type of belt that has been essential in enabling cars to transmit more power and meet the demands of today's more complicated systems. This belt is an advancement of the V-belt and features many longitudinal grooves in its construction. This kind of belt fits tightly into the grooves as tension rises, creating friction and effectively conveying torques with little power loss. The Poly V belt has emerged as one of the most preferred options among automakers because of its versatility and great efficiency.

What Is The Primary Distinction Between A Timing Belt And An Auxiliary Drive Belt?

 

The ability to transmit power between components such as shafts, pulleys, or sheaves is provided by driving belts. Despite the fact that they may seem the same, they each have two very distinct duties. The timing belt synchronizes the crankshaft and camshaft rotations to ensure that each cylinder's intake and exhaust valves open and close at precisely the same times.

On the other hand, the auxiliary belt, also known as the aux drive belt, is what transfers the crankshaft pulley's motion to the vehicle's various parts, including the alternator, which powers the electrical system and charges the battery while the engine is operating, and the power steering. Many pulleys connect it to the crankshaft and camshaft, with the tensioner pulleys resting on the exterior. The auxiliary drive belt often features parallel longitudinal grooves instead of notches and is typically somewhat smaller and thinner than the timing belt. In contrast, the timing belt nearly always has one side completely covered in notches or teeth. Find Best Auto Parts In Bulgaria online only at the website of Body Car Ltd. Visit the website now!
