More Information
Summary:The invention relates to a component for a vehicle transmission system, comprising: an element (18) suitable for securing to the crankshaft of a heat engine of the vehicle; and a device (30) for damping torsional oscillations, comprising a carrier (31) secured to the element (18), and at least one pendulum body (32) which moves in relation to the carrier (31), the pendulum body (32) being designed so as to be linked to a command value selected in such a way that the ratio of said command value to the order of excitation of the heat engine is higher than 1.1.
