Method of manufacturing coil spring assembly for torsional vibration damper, involves inserting inner coil spring into spring interior of outer coil spring and supporting inner and outer coil springs in longitudinal directions
Method of manufacturing coil spring assembly for torsional vibration damper, involves inserting inner coil spring into spring interior of outer coil spring and supporting inner and outer coil springs in longitudinal directions
The method involves providing an outer coil spring (26) and an inner coil spring (28) such that diameter of the outer coil spring is larger than the diameter of the inner coil spring. The inner coil spring is inserted into a spring interior (33) of outer coil spring. Two coil springs are supported by one another in longitudinal directions (4,6) of spring. Independent claims are included for the following: (1) coil spring assembly; and (2) torsional vibration damper.
