Abstract
1326309 Hydrodynamic torque converter VOITH GETRIEBE KG 24 Sept 1971 [24 Sept 1970] 44733/71 Heading F2C A hydrodynamic torque converter, constructed as shown with an impeller 2 (with blades 3), a turbine 4 (with blades 7) and a stationary reaction member 10 with blades 11 is characterized in that the outside diameter Dr of the turbine is 15 to 40% (and preferably 23 to 36%) larger than the impeller outlet diameter D P , the maximum thickness d of each turbine blade is located one-third of the way along the centre line thereof from the leading edge, the leading edge of each turbine blade has a radius of curvature r of substantially one quarter of the maximum thickness d, and the clear outlet area of the turbine is one quarter that of the impeller. The torque converter is for use as a starting torque converter, particularly in a rail vehicle, wherein the starting torque converter is used at lower speeds, where there is greater torque conversion, and another, cruising, torque converter is used for higher speeds where there is less torque conversion, the maximum efficiency of the starting torque converter of the invention occurring at a ratio n r /n p of 0À4 to 0À55, n r and n p being turbine and impeller speeds respectively.
