Specific implementation mode
To make the above purposes, features and advantages of the invention more obvious and understandable, below in conjunction with the accompanying drawings to the present invention
Specific embodiment be described in detail.
First embodiment
Referring to Fig.1, a kind of double mass flywheel 100, including the primary flywheel 10 of coaxial arrangement and secondary flywheel 20, primary fly
It is additionally provided with circumferentially arranged elastic mechanism 30 between wheel 10, secondary flywheel 20.Wherein, circumferential one end of elastic mechanism 30 with just
Grade flywheel 10 is relatively fixed, and the circumferential other end is relatively fixed with secondary flywheel 20.Primary flywheel 10, secondary flywheel 20 can be resisted
The elastic acting force of elastic mechanism 30 and realize relative rotation.
Double mass flywheel 100 is generally arranged between engine and gearbox, and primary flywheel 10 is suitable for being fixedly connected starting
The output shaft 200 of machine, output shaft 200 can be specifically spirally connected by the mounting hole 10a being arranged on primary flywheel 10 to be fixed on just
On grade flywheel 10.Secondary flywheel 20 is suitable for being fixedly connected the input shaft 300 of gearbox.
The power of engine is transferred to primary flywheel 10 by output shaft 200, and primary flywheel 10 rotates and makes elastic mechanism
30 occur elastic deformations, the elastic mechanism 30 after deformation can drive secondary flywheel 20 rotate and with driven input shaft 300 rotate with
Power is transferred to gearbox.Power through double mass flywheel 100 transmits, and can reduce the torsional oscillation of engine output shaft 200, make
Automobile has preferable NVH performances.
Theoretically, output shaft 200 and input shaft 300 are on same straight line always.But in power transmission process, by
It unavoidably will appear output shaft 200 and the not coaxial situation of input shaft 300 in reasons such as vibrations, and existing double mass flywheel
In two flywheels can not be radially movable, when output shaft 200 and not coaxial input shaft 300, double mass flywheel will produce larger
Inertial forces, influence auto NVH performance, or even damage double mass flywheel.
