VEHICLE CLUTCH RELEASE SLEEVE Russian patent published in 1998 - IPC

FIELD: transport engineering; clutches. SUBSTANCE: clutch release sleeve has ball radial-thrust bearing with rotating outer race and fixed inner race axially secured relative to first bushing of bearing. Flange of sleeve is installed by central hole on second bushing of sleeve. Ring projection is made on end face of first bushing opposite to end face of bearing outer race. Axial flanging is made opposite to outer surface of the same race on first bushing. Flanging with irregular-shape outer and inner surfaces is made on thinner portion of bushing on which flange is mounted. Each of these surfaces is outlined by three equal arcs, radii of arcs exceeding radii of circumferences limiting above-indicated inner and outer surfaces of second bushing. Centers of arcs are located in pairs on bisectors of central angles equal to 120 degrees, with displacement from axis of rotation of the bushing. EFFECT: simplified design, improved manufacturability of clutch release sleeve. 3 dwg
