Shock-absorbing device including a system for absorbing vibrations formed by an inertia beater

The device (10) has a main shock-absorber (30) comprising elastic units (42) with circumferential action interposed between drive washers (32A, 32B) and a web (34) that is connected in rotation to the washers. A vibration absorbing system i.e. inertia beater (90), comprises an inertia mass (92) and...

More Information
Summary:The device (10) has a main shock-absorber (30) comprising elastic units (42) with circumferential action interposed between drive washers (32A, 32B) and a web (34) that is connected in rotation to the washers. A vibration absorbing system i.e. inertia beater (90), comprises an inertia mass (92) and a crown shaped inertia mass (93) connected to the web of the shock-absorber by elastic tabs (94, 94') of the beater. The tabs comprise ends (96, 96') connected to the inertia mass, and other ends (98, 98') connected to the web of the shock-absorber. The tabs are made of metal e.g. XC70-steel.
