Dual Mass Flywheel

Dual mass flywheel is an important automotive component designed to improve the performance, fuel economy, and driving experience of automobiles.

Its design concept and working principle combine multiple functions such as shock absorption, smooth transmission, and improved comfort. This new structure divides the traditional flywheel into two parts, with one part maintaining its original position and continuing to undertake the responsibilities of starting and torque transmission, known as the first mass; And the other part is cleverly placed on the transmission side to enhance the rotational inertia of the transmission system, known as the second mass. This design introduces an intermediate Shock Absorber to share and balance the fluctuations in Engine output torque, and is connected through a series of springs and shock absorbers to form a non rigid connection method. When the engine output torque fluctuates, this connection allows the two parts of the dual mass flywheel to move relative to each other, thereby achieving absorption and buffering of torque fluctuations.

The introduction of dual mass flywheels has brought multiple advantages to the automotive transmission system, including reducing the impact of engine torque fluctuations on the transmission system, reducing the generation of vibration and noise, and thus improving driving comfort. In addition, this shock absorption design can effectively disperse and absorb impacts, extending the service life of the transmission system. The damping effect of the dual mass flywheel reduces the load on the transmission system, helps to reduce energy loss, and improves fuel efficiency.

One of the manufacturers of LUK brand dual quality flywheels, dedicated to providing high-quality products and services to meet the demands of the global market. Widely applicable to various car models, including Volkswagen, Audi, BYD, Geely, Great Wall Motors, Peugeot, Citroen, Honda, Ford, Land Rover and other series of models, to meet a wide range of needs.
