Since its launch in 1985, the LuK Dual Mass Flywheel (DMF) has been fitted as original equipment in ever-increasing numbers of vehicles. When a conventional single-mass flywheel  and conventional clutch reach their torsion angle limits at around 18°, the DMF, with its decoupled dual masses and a torsion angle of up to 100°, can absorb …

Transmission sensors record the transmission speed. This information is needed by the ECU to adjust the shifting pressure and for the decision which gear must be chosen. Function There are two different types of transmission sensors, a hall sensor and an inductive pickup. Their function is send voltage signals produced by changing magnetic fields developed …

Dual Mass Flywheels (DMFs) set a new standard for drivetrain noise insulation and vibration damping when launched by LuK in 1985. A total of 63 million DMFs have since been manufactured, and one in three cars on European roads currently use DMF technology to aid comfort and reduce fuel consumption and CO2 emissions. Now pendulum-type …

GLYCO explains the vital role of bearing clearances in modern engines. As engine builders continue to extract more power from less fuel, modern engines are subjected to greater temperatures and loads. With bearings taking the strain, bearing clearances are microscopic spaces with huge impact. BEING CLEAR ABOUT CLEARANCESA bearing clearance is the difference between the …
