Abstract:
A shock absorbing device having an axial friction brake for the minimization of dynamic motion while allowing motion, seen as especially useful as an alternative to, or in the replacement of, snubber devices. The shock absorbing device has a movable shaft which is attached to the object to be supported during dynamic motion at one end and a frictional surface which contacts a brake assembly at the other. The brake assembly is located within a housing, which is directly or indirectly attached to a nonmovable support, and is provided with one or more friction pads which contact the frictional surface. The brake assembly may be adjustable for varying load amplitude.
