Damper Isolator Pulleys combine torsional vibration damping and a function for isolating the belt drive system from crankshaft irregularities. The damper reduces the torsional vibration amplitudes of the crankshaft, while the integrated isolator isolates the belt drive system from irregularities which cause belt effects like flapping.
The practical Corteco kits save time when placing orders and guarantee satisfied customers. Our constantly extending range already covers 300 of the most important vehicle types.
Corteco is the aftermarket brand of the Freudenberg Group which accompanies Vibracoustic. Vibracoustic is a leading global automotive noise, vibration and harshness expert. Because of this, Corteco has the unique ability to offer parts made to precise OE specifications, ensuring exceptional reliability and ride performance.
Crankshaft irregularities, especially at low speed, can lead into noise or to an early failure of the belt and belt drive components. A crankshaft isolator rubber effectively eliminates these vibrations directly at source. At the same time, the torsional vibration damper in the isolator pulley reduces torsional vibrations within the crankshaft.
Only original quality pulleys with new bolts guarantee easy mounting and the highest degree of safety.
In Fluid TVDs, the fluid provides the damping and stiffness whereas the inertia ring serves as the vibration mass. Specially designed bearings enable relative movement of the torsional vibration damper and the optional pulley secures the connection to the belt drive.
In many applications it provides the torque transmission to the auxiliary belt drive and with a special surface treatment it can be equipped with a high torque feature to support even high loaded applications. Pressed TVDs are a cost-effective way to achieve this goal.
The Overrunning Damper Isolator Pulley combines a damper isolator pulley and one-way-clutch feature. It addresses the negative effects of low belt tension to reduce friction and help reduce fuel consumption. It also retains the excellent isolation characteristics of familiar rubber isolators.
Sprocket Dampers significantly reduce the noise and vibration amplitudes of the chain drive. They prevent the chain-whine noise of chain-driven diesel motors, caused by the chain-link striking the chain wheel teeth.
Elastomer types provide excellent damping and stiffness characteristics. The inertia ring serves as the vibration mass for the Vulcanized TVD. In many applications it provides the torque transmission to the auxiliary belt drive.
The typical crankshaft vibrations are compensated by employing high quality decoupled belt pulleys. This minimizes the transmission of vibrations to other vehicle components and the associated effects on the entire vehicle. So you can enjoy undisturbed ride comfort. Decoupled pulleys also work to minimize stressed placed on the entire belt-drive system created by increased engine starting and stopping in modern vehicles equipped with start-stop technology.
The decoupled belt pulley is joined to the torsional vibration damper by a highly elastic elastomer part, thereby offering optimum damping properties.
Benefits:
Poorly engineered or copied pulleys will cause the risk of severe damage.
It’s recommended that bolts and washers are replaced anytime the pulley is replaced rather than being reused. Corteco offers complete pulley/bolt kits as well as supplementary bolt kits so that you can service the complete job with one part number.
Benefits:
Our recommendation: replacing the bolts with the pulley
