Product Description:

Crankshaft pulley                                                                                              

OE number: 31401194

Applicable vehicle type: For Volvo 

As a key component of the engine, the crankshaft pulley of the car, although seemingly ordinary, plays a pivotal role in the car's power transmission system and has a profound impact on the performance, reliability and overall operating status of the vehicle. 

(I) Power transmission core

The crankshaft pulley is like the "power hub" of the car engine, and is a bridge connecting the engine crankshaft and many accessories. It is tightly wrapped around the front end of the engine crankshaft. As the crankshaft rotates at high speed, it relies on its own circular motion to efficiently transmit the crankshaft's rotational power to a series of important accessories such as the generator, water pump, power steering pump, and air conditioning compressor through the transmission belt. Driven by it, the generator continues to operate to charge the car battery, maintain the stable operation of the entire vehicle's electrical system, and ensure the normal operation of vehicle starting, lighting, audio and other equipment; the water pump relies on the power of the crankshaft pulley to drive the coolant circulation to ensure that the engine operates efficiently at an appropriate temperature and prevent the engine from being damaged by overheating; the power steering pump uses the power it transmits to assist the vehicle's steering, making driving control easier and more comfortable; the air conditioning compressor works under the drive of the crankshaft pulley to create a comfortable temperature environment in the car. ​

(II) Cushioning and shock absorption

When the engine is running, the reciprocating motion of the piston and the impact force generated by the combustion explosion will cause the crankshaft to vibrate violently. The crankshaft pulley is usually specially designed with a buffer layer made of rubber or other elastic materials integrated into it. When the vibration of the engine is transmitted to the crankshaft pulley, the buffer layer acts as a "shock absorber", effectively absorbing and alleviating these vibrations, reducing the impact of vibration on other parts of the transmission system, making the power output smoother and smoother, reducing the noise and component wear caused by vibration, and extending the service life of each component. ​

(III) Overload protection

Some advanced crankshaft pulleys have overload protection. When an accessory has excessive resistance or jams due to a fault or other reasons, causing the load of the transmission system to increase sharply in an instant, the special structure inside the crankshaft pulley (such as the use of fusible materials or a specific mechanical structure) will take effect, cutting off power transmission by slipping, fusing, etc., avoiding damage to the engine crankshaft and other key components due to overload, providing a layer of safety for the engine.
