CLUTCH WITHDRAWAL MECHANISM Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: friction clutch mechanism is positioned between engine and gear box. Clutch withdrawal mechanism has pressing out bearing for driving clutch actuating members and is supported by bearing part arranged at side adjacent to gear box. Bearing part has supporting member which takes up force applied to pressing out bearing, when pressing out bearing drive member is actuated. Pressing out bearing is positioned for axial displacement and rotation relative to bearing part. Device for axial displacement of drive member is disposed between supporting member and drive member rotating relative supporting member. Balancer positioned between pressing out bearing rotary ring drive portions and bearing part is adapted for balancing axial displacements of clutch drive portions to which load, developed during service life of friction clutch mechanism, is applied by clutch withdrawal mechanism. As a result, free play is prevented during stroke of pressing out bearing. EFFECT: increased efficiency and enhanced reliability in operation. 41 cl, 13 dwg
