Abstract: 1,108,818. Hydrostatic transmissions. SOC. ANON. ANDRE CITROEN. 21 July, 1965 [28 July, 1964], No. 31093/65. Heading F2D. An hydrostatic transmission for a vehicle comprises swash plate pump and motor units 3, 10, the pump swash plate 5 carrying an abutment 28 acting as a reaction member for a compensating link 17 whose ends are acted upon by piston units 18, 25 respectively subjected to speed responsive pressure from an engine driven unit 21 and pump output pressure in line 7. In addition the pump and motor swash plates 5, 12 are acted upon by opposed pairs of piston units 41, 42 and 48, 49, the units 41, 48 being connected by lines 40, 47 to a distributer valve 32 and the units 42, 49 to the pump suction line 14. As shown the system is arranged for low speed conditions, the piston units all being in their uppermost positions for minimum and maximum tilting of the pump and motor swash plates 5, 12 respectively. Piston unit 41 is vented to atmosphere and unit 49 is connected to the right-hand chamber 35 of valve 32. With increasing speed the system pressure increases so that piston 25 moves to the right and valve 18 to the left and the pressure in chamber 34 operates valve 32 to cause pistons 41, 42 to move downwards to tilt pump swash plate 5 to the position for maximum capacity, Fig. 2 (not shown). At high speed pressure in chamber 35 causes valve 32 to operate to move pistons 48, 49 downwards, so that the motor swash plate 12 is tilted for minimum capacity. The pressure generator unit 21 is of the centrifugal type and the pressure may be modified by movement of the accelerator pedal, Figs. 4-11 (not shown).
