The invention provides a double-mass flywheel adjusting the damping and rotary inertia ratio self-adaptively. The double-mass flywheel comprises a primary flywheel, damping ring plates, a secondary flywheel, a force transferring plate and damping and rotary inertia adjusting devices, wherein the force transferring plate is installed on the secondary flywheel, the damping and rotary inertia adjusting devices are located inside the force transferring plate, move radially inside the force transferring plate and are evenly distributed inside the force transferring plate, each damping and rotary inertia adjusting device comprises a plurality of adjusting units distributed along the axis of the force transferring plate, the adjusting units slide radially along the force transferring plate, and gaps between the plurality of adjusting units and the damping ring plates decrease as central angles of adjusting unit distribution increase. By means of the double-mass flywheel adjusting the dampingand rotary inertia ratio self-adaptively, damping and rotary inertia ratio self-adaptive adjusting is realized, and the double-mass flywheel is made to have a good torsional vibration attenuation effect under different working conditions.
Description
technical field [0001] The invention relates to the field of automobiles or the field of dual-mass flywheels, in particular to a dual-mass flywheel for adaptively adjusting the ratio of damping and moment of inertia. Background technique [0002] The dual-mass flywheel torsional vibration damper divides the engine flywheel into two parts, the primary flywheel and the secondary flywheel, and uses a damping spring to connect with the damping mechanism. The power output of the engine is transmitted to the primary flywheel, and the secondary flywheel is driven to rotate through the damping spring. The dual-mass flywheel changes the moment of inertia distribution of the engine flywheel, and has smaller torsional stiffness, which can effectively reduce the low-order natural frequency of the drive train, thereby attenuating torsional vibration. Consumption plays an important role. [0003] In the process of theoretical research and practical application, it has been proved that d...
