Valeo's Long Travel Damper Dual Mass Flywheel Offers Significantly Improved Acoustic Comfort and Reduced Vibration

FRANKFURT, September 15 /PRNewswire/ -- The long travel damper dual mass flywheel (LTD DMF) significantly reduces perceived vibrations and engine noise. This represents a major step forward in powertrain filtration technologies. This advance is especially important because the fuel-saving engines now being developed have higher torque and, consequently, generate greater vibrations, especially at low speed. The LTD DMF absorbs torque vibrations generated by the engine to the transmission, thereby increasing the comfort of the vehicle's occupants.

Two compact filtration devices give the LTD DMF the qualities to become an essential component in tomorrow's conventional high-performance engines as well as for hybrid powertrains, which have the strictest installation constraints. In addition to the well-known dual mass flywheel technology, the LTD DMF integrates a long travel damper developed by Valeo for torque converters in automatic transmissions. This combination allows it to provide optimal filtration, especially during start-up, thanks to a maximum angular displacement of 80degrees, as well as exceptional performance level in all engine regimes.

Valeo's long travel damper dual mass flywheel offers comfort levels previously unknown on the most fuel-efficient engines. The NVH (Noise-Vibration-Harshness) level and ease of gear changes offer remarkable driving comfort for the most vibration-prone engines.
