Abstract
Description
technical field
[0001] The invention relates to a shock-absorbing pulley In more detail, it relates to a lightweight damping pulley mounted on a crankshaft of a vehicle engine, which is lightweight and easy to manufacture, and has required rigidity and durability. Background technique
[0002] Generally, torque periodically acts on the crankshaft of the vehicle engine, so torsional vibration occurs. This torsional vibration increases as the rotational force of the crankshaft per cylinder increases, and increases as the length or stiffness of the crankshaft increases. When the crankshaft rotates at a certain number of revolutions, this torsional vibration resonates with the natural vibration of the crankshaft itself to form a strong vibration, which makes the ride uncomfortable and causes damage to the timing gear or the crankshaft.
[0003] In order to reduce this torsional vibration, a torsional vibration reduction device integrally formed with the crankshaft pulley is p...
