What does the dual-mass flywheel of Wuling Hongguang S mean?
1 Answers
The full name of the dual-mass flywheel is dual-mass flywheel. The dual-mass flywheel is located between the engine and the transmission, and its main function is to store the energy and inertia outside the engine's power stroke; the four-stroke engine only has one power stroke, and the energy for intake, compression, and exhaust comes from the energy stored in the flywheel; the balance of the engine mainly relies on the balance blocks on the crankshaft, and single-cylinder engines specifically have balance shafts. The structure of the single-mass flywheel and dual-mass flywheel in Wuling Hongguang is different: The structure is equivalent to dividing the traditional solid flywheel into two parts. One part is called the first mass, which is used to compensate for the engine's inertia; the other part is called the second mass, which is used to increase the transmission's inertia; the two parts are not rigidly connected internally, but through elastic elements with damping effects (such as curved spiral springs or other types of damping elements), the impact of engine vibration on the vehicle's driving force can be significantly reduced without the need for a clutch plate with a torsional damper. The combination of the single-mass flywheel and dual-mass flywheel in Wuling Hongguang is different: Compared with the combination of an ordinary solid flywheel and a damping clutch, because the DMF has more space, the springs are easier to arrange, and the damping effect is more excellent, almost completely isolating the engine's vibration from the transmission, especially providing excellent filtering for the unstable movement of the engine at low speeds.
