Abstract
A conical disk assembly including a shaft carrying an axially movable disk and having a fixed disk rigidly connected to the shaft. A support ring having first ramp surfaces facing the axially movable disk is carried on the shaft, and a rotatable sensing piston having second ramp surfaces that face the first ramp surfaces is axially movable along the shaft. Rolling elements are positioned between the ramp surfaces, and when the ramp surfaces are rotated relative to each other, the rolling elements move the sensing piston axially along the shaft. A guide ring is rigidly operatively connected to the axially movable disk and includes guide surfaces associated with the ramp surfaces for radially supporting the rolling elements. The guide ring and the support ring are connected with each other in a non-rotatable and axially movable manner to facilitate assembly of the conical disk assembly.
