Dual mass flywheel capable of achieving nonlinearity torsion character and adapting to automobile multiple work conditions

A dual mass flywheel capable of achieving the nonlinearity torsion character and adapting to automobile multiple work conditions comprises a first flywheel body and a second flywheel body which are coaxially arranged, shock absorbers are arranged between the first flywheel body and the second flywheel body, and the first flywheel body and the second flywheel body oppositely rotate. The first flywheel body and a spline shaft sleeve are connected through a third rivet, the spline shaft sleeve is connected with an output shaft of an engine, a connecting disc is connected with the second flywheel body through a second rivet, and the second flywheel body is fixedly connected with an input shaft of a speed changing box. The dual mass flywheel is used so that the continuous variable rigidity character in which torque character nonlinearity increasing is achieved along with torsion angle increasing can be achieved, and accordingly, torsion vibration isolating of an automobile under multiple work conditions such as en
