A VIBRATION FILTER FOR A TRANSMISSION WITH AUTOMATIC, CONTINUOUS OR DISCONTINUOUS, GEARCHANGE, ESPECIALLY FOR A MOTOR VEHICLE

摘要

The transmission filter, containing a torsion damper between a driving component such as a primary flywheel (10) and a driven component or secondary flywheel (20) on a shaft (21), has elastic elements in the form of radial coil springs (34) of variable rigidity. The primary flywheel is connected to a driving shaft (11) by a plate (19) and bolts (17), while the secondary one is connected to the driven shaft (21) by a hub (26). The coil springs are mounted on rods (35) with thrust seats (36) on their outer ends and having their inner ends pivoted to axles forming the torsion damper's output. The springs are also container in housings (38) with their outer ends pivoted to shafts forming the damper's input.
