Abstract

A clutch release device for use in combination with a clutch having a declutching member that is rotatable about the axis of the clutch comprising a fixed cylindrical guide having an axis substantially coaxial with the axis of the clutch but subject to misalignment with respect thereto, and a sleeve which surrounds the guide and is slidable therealong. The sleeve is provided with an end section that extends radially outward from the sleeve. An inner ring surrounds the sleeve and is spaced radially therefrom, the inner ring also being spaced axially from the radially extending end member of the sleeve and having a driving element attached to the end opposite the end section of the sleeve for engagement with the declutching member. A housing, which surrounds the sleeve, is provided with a flange that extends radially inward between the inner ring and the end section of the sleeve, and an outer ring is secured to the inner surface of the housing opposite the inner ring and spaced therefrom to permit bearing means to be interposed between the inner and outer rings. An annular member, having a curved surface facing the flange and a plane surface facing the end section, is interposed between the housing flange and the end section of the sleeve, the annular member being movable in a radial direction while remaining in contact with the flange. Resilient means, which may be in the form of a leaf spring, is attached to the sleeve and contacts the flange to urge the flange against the curved surface of the annular member.
