Valeo's Long Travel Damper Dual Mass Flywheel Offers Significantly Improved Acoustic Comfort and Reduced Vibration
FRANKFURT , September 15 /PRNewswire-FirstCall/ -- 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.
Valeo is an independent industrial Group fully focused on the design,
production and sale of components, integrated systems and modules for cars
