DISK BUMPER WITH PENDILUM SUSPENSION Russian patent published in 2015 - IPC F16F3/02 F16F1/32 

FIELD: machine building.

SUBSTANCE: bumper consists of resilient element interacting with base of case and pendulum suspension. The pendulum suspension is made in form of the thread rod having spherical profile at one end and thread bushing connected with it, and having spherical profile. The spherical profiles interact with cone surface of bottom and top plates. Package of resilient elements of disc type contains connected with each other external and internal ring resilient cone discs. Discs are located between the base and cover.
