Abstract
1,246,196. Hydro-dynamic transmission control; friction clutches. TWIN DISC Inc. 11 Dec., 1969 [26 Dec., 1968], No. 60462/69. Headings F2C and F2L. A power transmission for a crane wherein an engine E drives the impeller I of a stationary housing type torque converter TC through an hydraulically actuated continuously slipping multi-disc clutch MC, a single control valve CV controls the engagement of the clutch MC and the filling of the torque converter TC and a bleed passage 20 vents the torque converter when its turbine T rotates reversely during load lowering. The control valve CV regulates the loading pressure supplied from a pump P to a relief valve RV and a clutch discharge valve OV. The valve RV regulates the pressure supplied by a pump 17 to the torque converter working circuit within the range from zero to 45 p.s.i. whilst a valve BPV limits the pressure supplied to the torque converter working circuit. The loading pressure supplied to the valve OV acts, in opposition to centrifugal force and the action of a spring OVS, on the outer end of a valve spool 23 to move the latter inward and close an exhaust passage (26) from the clutch servo chamber (25) which is continuously supplied with pressure liquid from the pump 36 through a restriction (28C). A centrifugal governor G driven by the torque converter output shaft 13 modulates the loading pressure supplied by the control valve CV to the clutch control valve OV to limit the maximum output speed of the torque converter. The maximum output speed of the torque converter may be adjusted by a lever 33 which loads the governor G. Liquid bled from the torque converter through the bleed passage 20 passes through the clutch to cool the latter.
