US 2022/0397175 A1 · TORSION SPRING DEVICE, BEARING, AND VIBRATION DAMPER

Abstract

Torsion spring device includes an outer housing, an inner housing located in the outer housing, and an elastic element. The elastic element supports the inner housing relative to the outer housing such that a restoring force is built up between the outer housing and the inner housing as a result of a deflection caused when the outer housing and the inner housing are rotated relative to one another. The restoring force-deflection curve can be adjusted by a choice of shape and/or material of the outer housing, of the inner housing, and of the elastic element and/or wherein the hysteresis can be adjusted by a choice of shape and/or material of the outer housing, of the inner housing and of the elastic element.

A torsion spring device (1, 101-106) comprising

an outer housing (2),
an inner housing (3) arranged in the outer housing (2) and
an elastic element (4), which supports the inner housing (3) relative to the outer housing (3) such that a restoring force is built up between the outer housing (2) and the inner housing (3) as a result of a deflection caused when the outer housing (2) and the inner housing (3) are rotated relative to one another,
wherein
the restoring force-deflection curve can be adjusted by a choice of shape and/or material of the outer housing (2), of the inner housing (3) and of the elastic element (4) and/or wherein the hysteresis can be adjusted by a choice of shape and/or material of the outer housing (2), of the inner housing (3) and of the elastic element (4)
