Automotive drive belts need to pay attention to the following points in the process of use:

Regular inspection: Regularly check the wear and tension of the drive belt and replace the badly worn drive belt in time.
Keep clean: Keep the drive belt and pulley clean to prevent oil, dust, etc. from adhering to the drive belt and affecting the transmission efficiency.
Correct installation: When installing the drive belt, make sure that the two axes of the pulley are parallel and the groove of the pulley is in the same straight line, and avoid using tools to forcibly hang in to avoid damaging the drive belt.
Adjustment of tension: According to the requirements of the transmission system, adjust the tension of the transmission belt to ensure that the belt does not slip or come loose in the transmission process.

There are several factors to consider when selecting the right automotive drive belt:

Transmission power: Select the right type of drive belt according to the power required by the transmission system.
Compactness: If the drive system requires a compact structure, you can choose a multiribbed belt.
Working environment: consider the working environment in which the drive belt is located, such as temperature, humidity, oil, etc., and choose the appropriate material and model.
Brand and quality: choose famous brand and reliable quality transmission belt to ensure the stability and safety of the transmission system.

Multi-wedge belts are mainly composed of the following parts:

Top fabric (surface fabric): heat-resistant, oil-resistant, abrasion-resistant, anti-cracking.
Top rubber: Increase the friction with the pulley.
Cushion rubber (rubber bonding): maintains the cohesion between the core rope and the rubber wedge while protecting the core rope.
Cord (tensile body): Skeleton structure, a special heat-treated core cord, which gives the belt a high modulus and resistance to impact loads.
Bottom rubber (rubber wedge): Different models of wedge rubber are generally added with different fibers. The fiber-reinforced rubber wedge can support the core rope and at the same time make the belt have good abrasion resistance.

Multi-wedge belts (also known as composite v-belts) have the following advantages over V-belts:

Large transmission capacity: Multi-wedge belts have multiple wedge surfaces, which increases the contact area between the belt and the pulley, thus increasing the transmission capacity.
Smooth running: Multi-coupling belt has less vibration in the transmission process and runs more smoothly.
Long service life: the elongation of multi-coupling belt is small, tensile and fatigue strength is high, so the service life is longer.
Compact structure: when transmitting the same power, the use of multi-coupling belt can make the diameter and width of the pulley reduce, the structure is more compact.

V-belt, also known as fan belt or cut edge V-belt, is a transmission belt with a V-shaped cross section. It is designed to create a good wedge effect between the belt and the pulley to improve transmission efficiency.V-belts are widely used in automobile engine systems to transmit power to various accessories.

Automotive drive belt is an important part of automotive power transmission system, which is mainly used to connect the engine with various accessories (such as generator, air-conditioning compressor, water pump, etc.) to realize the transmission of power. Common automotive drive belts include V-belts, multi wedge belts and so on.

When installing automotive drive belts, you need to pay attention to the following points: make sure that the drive system has stopped running and disconnect the power supply or battery; check whether the pulleys and drive belts are clean and free of damage; install the drive belt correctly in accordance with the requirements of the drive system to avoid distortion or misalignment; adjust the tension of the drive belt to the proper range to ensure that the drive belt does not slip or loosen during the transmission process; and lastly, restart the drive system to check whether the drive belt is running smoothly and is not loosened. Finally, restart the drive system and check whether the drive belt runs smoothly without abnormal noise.

V-belts and spaghetti belts differ in construction and function, so direct replacement is generally not recommended. V-belts offer higher drive efficiency and longer service life, and are capable of driving multiple attachments at the same time, reducing the complexity and space requirements of the drive system. If it is necessary to replace a V-belt with a multiribbed belt, it is necessary to ensure that other components of the drive system (such as pulleys) are also replaced or adjusted accordingly to ensure the proper operation and performance of the drive system.

To determine whether the drive belt needs to be replaced, you can use the following methods: observe the wear of the drive belt, such as cracks on the surface, severe wear or deformation; check the tension of the drive belt, if it is too loose or too tight, it may lead to a decrease in transmission efficiency or damage; listen to the sound of the transmission system when it is running, if it makes an abnormal noise, it may be a sign that the drive belt is slipping or is damaged; finally, according to the recommendations of the vehicle maintenance manual, follow the instructions of the vehicle maintenance manual to ensure that the drive belt is in good working order. Finally, replace the drive belt regularly according to mileage or time as recommended in the vehicle maintenance manual.

Automotive drive belts wear out mainly due to the following reasons: aging of the material due to prolonged use, roughness or damage to the pulley surface, improper belt tension, overloading of the drive system, and impurities such as oil and dirt in the working environment adhering to the belt, which increases friction and wear.
