Abstract

602,020. Friction clutches reversing gear. FORD MOTOR CO., Ltd. Oct. 4, 1945, No. 25886. Convention date, Jan. 26. Class 80 (ii)] [Also in Group XXIX] In a hydraulic torque converter a friction clutch 19 carrying a spring-loaded valve 20 is secured to the runner 15. The valve controls a passage admitting fluid between the clutch surface and the fly-wheel 14 of the impeller 13, said passage being in communication with a passage in the fly-wheel controlled by a spring- loaded valve 21. At a predetermined speed, centrifugal force causes the valve 20 to close, preventing flow of fluid, and the valve 21 to open, bleeding the cushioning fluid between the clutching surface and the fly-wheel so that the clutch engages to give direct drive. A conventional planetary gearing in the gear-box 12 provides a forward, a reverse, a neutral and a positive lock, and a band brake 31 is also provided.
