Abstract
810,458. Hydromechanical variable-speed gear. WEINRICH, H. March 9,1955 [March 9, 1954], No. 6965/55. Class 80 (2). [Also in Group XXIX] A turbo converter is driven through a torque-splitting planet gear and comprises a pump 8 and turbine 10 which rotate in opposite directions, the turbine blades being disposed within the pump blades. As shown in Fig. 1 the working circuit includes guide blades 15 fast with a stationary casing 9 and guide blades 16 which are freely rotatable under starting conditions and which are held stationary by a brake for normal running. The brake ring 18 is applied by springs, and is released by the pressure within the working circuit which acts through ducts 20 on pistons 19 fixed to the ring. In the modifccation, of Fig. 2 guide blades 21 are axially displaced to within the stationary core of the converter under starting conditions. Under starting conditions the pressure in the working circuit at the guide blades 15 is great enough to open a valve 23 against the pressure between the turbine and pump, and the pressure on the shell of guide blades 21 moves them into the core against spring pressure. Forward and reverse drive.-An input shaft 1. drives a ring gear 5 of the planet gear, the planet carrier of which is fast with an intermediate shaft S. The sun gear is fast with the pump 8. A gear wheel 31 is splined to an output shaft 29, and for forward drive the gear 31 is in its lefthand position in which it has a toothed connection 32 with a disc 35 fast with the intermediate shaft and in which it engages a gear on a shaft 34 geared to the turbine. For reverse drive the intermediate shaft S is held stationary by a pawl engaging disc 35, and gear 31 is moved to its right-hand position in which it engages a gear on the shaft 34 via an idler gear. Making up leakage.-A gear pump 37 supplies make-up liquid to the working circuit through ducts in the intermediate shaft S, and some of the liquid escaping from the working circuit collects in annular chambers in the bearings of the pump and turbine and is returned to the circuit through these ducts.
