Vibration damper, associated damping mechanism and propulsion assembly

A torque converter, comprising:

• a vibration damper of the inertial beater type, the vibration damper including:
• two rotating members guided rotationally around an axis of revolution, wherein one of the two rotating members is an inertial flywheel oscillating around the axis of revolution and the other of the two rotating members is a member to be damped, wherein the member to be damped is arranged to be driven by a torque following a torque path between a driving member and a driven member, wherein the inertial flywheel is arranged to be connected kinematically to the torque path between the driving member and the driven member solely by way of the member to be damped;
• and
• one or more connecting modules between the two rotating members, permitting a relative angular displacement θ between the two members rotating around the axis of revolution on the two sides of a reference relative angular position, wherein each connecting module includes:
• a cam follower associated with a first of the two rotating members, and
• a cam track connected resiliently by a resilient element to a second of the two rotating members, wherein the resilient element is capable of being deformed to ensure resilient bracing of the cam track against the cam follower, thus permitting the cam follower to be displaced over the cam track when the two rotating members are rotating relative to one another on the two sides of the reference position.
