What is the difference between Wuling Motors' dual-mass flywheel and single-mass flywheel?

[DeDawson]

Wuling Motors' dual-mass flywheel and single-mass flywheel differ in the following aspects: 1. Different structure: The structure is equivalent to dividing the traditional solid flywheel into two parts. One part is called the primary mass, which compensates for the engine's inertia; the other part is called the secondary mass, which increases the transmission's inertia. The two parts are not rigidly connected internally but are linked through elastic elements with damping effects (such as curved spiral springs or other types of damping elements). This design can significantly reduce the impact of engine vibration on the vehicle's driving force without the need for a clutch plate with a torsional damper. 2. Different combination: Compared to the combination of a conventional solid flywheel and a damping clutch, the DMF (dual-mass flywheel) has more space, making it easier to arrange springs, resulting in superior damping effects. It almost completely isolates the engine's vibration from the transmission, providing excellent filtering for the engine's unsteady motion at low speeds.
