Abstract:
A clutch release assembly for use in a motor vehicle comprising:a bearing having an inner race and an outer race and having a release sleeve formed integral with the inner race and having an axis of rotation around which the outer race rotates relative to the inner race; a cover formed of metal receiving at least in part the bearing having a radially inwardly extending flange partially closing a first end and having an open second end wherein the radially inwardly extending flange has an inner diameter sized to permit the release sleeve to pass therethrough and to prevent the bearing from passing therethrough; a housing fixed to the second end of the cover and together with the cover defining a cylindrical cavity therein centered on the axis of rotation wherein the bearing is disposed within the cylindrical cavity and is oriented to have its release sleeve extending past the radially inwardly extending flange, the housing being formed of metal; a low friction bushing fixedly disposed within the cylindrical cavity and having an inside diameter smaller than an inside diameter of the inner race; a spring axially disposed between the bushing and the bearing, the spring sized to engage the outer race and biasing the outer race against the cover; two L-shaped lugs formed on opposite sides of one of the cover and the housing and extending radially therefrom, the lugs each defining a circumferential engagement surface in a plane normal to the axis and facing toward the bearing and an axially extending engagement surface normal to the circumferential engagement surface wherein tips of the arms of a clutch yoke would engage the circumferential engagement surface to axially displace the release assembly and further wherein the axially extending surfaces prevent rotation of the housing by engagement with the tips of the arms.
