Mass flywheel


There is a case where the reciprocating piston engines produce rotating vibrations in the flywheel, which are caused by the lack of continuity in the development of combustion. This is why the dual mass flywheel prevents these rotating vibrations from increasing, passing through the motor path and causing damage such as resonance oscillations.

These oscillations are shown externally in the form of annoying sounds. Summing up the sounds and the oscillations, together with a kind of rattle in the gear changes, the tremor of the body and some vibrations caused by the alternative load of the engine, brings as a consequence a discomfort in sounds and would not allow comfort to the time to drive our car.

What is the purpose of this car part

The dual mass flywheel is the one in charge of eliminating the vibrations of the kinematic chain, trying to avoid unwanted sounds and guaranteeing a high riding comfort. The secret of this product lies in the two divided masses it possesses.


Mass flywheel

While the primary mass rotates in a manner that is integral to the engine, the other mass, which would be secondary, rotates in a damping manner and uniformly to the transmission, which is joined by means of a damping system that yields an oscillation between the two masses of the steering wheel. And an extra on it, the particular vibrations that are caused by the rotary motion of the motor are shock absorbers.

Fflywheel is composed of two inertial masses

As its name says, a dual mass flywheel is composed of two inertial masses, primary and secondary. These two inertial masses are connected to each other by a damping system and rotatably arranged against each other, by means of a rigid radial movement, or of a friction bushing.

The primary inertial mass with starting crown designated to the engine is as firm as possible screwed to the crankshaft. Together with the cover of the primary, it surrounds a hollow space that creates the spring channel, therefore, the damping system consists of curved springs, which are in sliding guides in the spring channel and meet any requirement for an “ideal” cushion that completes a minimum job. The sliding guides mentioned above, ensure a very good driving, and the load of fat that fills the spring channel reduces the friction between those and the curved springs.

Focusing on the elements of the biomass steering wheel, 2 of them are the most essential in this piece:

  • Primary Inertia Rate:

    This is attached to the engine crankshaft. In it is a moment of inertia, it forms the same unit with the crankshaft. When comparing to a conventional flywheel, with the primary inertial mass of the biomass flywheel, it is clearly seen that the latter possesses a highly superior inflection.
  • Secondary inertial mass:

    It is a connection of the dual mass flywheel to the kinematic chain in the gearshift area. In a collaborative way with the clutch, it transmits the muted torque from the dual mass flywheel. The clutch housing is screwed to the motor.
