IMPROVEMENTS IN A FLUID ACTUATED CLUTCH ASSEMBLY

摘要

A clutch-bearing release assembly (10) axially movable by fluid pressure in an annular cavity (66) acting on a piston (32) having alignment means (clearance between the piston and the cavity) separate from the clutch release bearing (34) to align this with the axis of rotation (x2) of the clutch (26). The inner end (88) of the piston may be spaced from the annular walls (68, 70) of the cavity by suitable mounting this end on an adjacent seal (86).
