DRIVETRAIN FOR A HYBRID OR ELECTRIC VEHICLE FITTED WITH AN DYNAMIC ABSORBER IN TORSION
A drivetrain for motor vehicle including an electric motor and a reduction mechanism designed to transmit the driving torque to the wheels of the motor vehicle. The electric motor includes a rotor equipped with a rotor shaft, the rotor shaft being rotationally coupled to a primary shaft of the reduction mechanism. The drivetrain further includes a dynamic absorber in torsion, the dynamic absorber in torsion having a support element, an inertial mass which is mounted with the ability to rotate about an axis X with respect to the support element and elastic members which oppose the relative rotation of the inertial mass with respect to the support element about said axis X.
