Abstract: 786,691. Variable-speed gearing. SOC. PER AZIONI CAMBI IDRAULICI BADALINI. Nov. 29, 1955 [Dec. 10, 1954], No. 34131/55. Class 80 (2). A variable-speed gear providing a continuous speed variation over two ranges comprises a closed-circuit hydraulic swash-pump and motor transmission giving a parallel drive to a driven shaft directly and through a countershaft gear. The cylinder block 5 of the pump 2 is secured to the driving shaft 4 and the swash ring is supported through a bearing 11 by a casing member 8 secured to the countershaft 39. A sliding sleeve 45 on shaft 39 is adapted to clutch alternatively gears 43, 44 to the shaft to drive gears 37, 38 respectively on the driven shaft 35 at different ratios. The output and return circuits of pump 2 pass through a distributing plate 7 and ducts 25, 30 to the motor 3, the cylinder block 12 of which is secured to a shaft 18 connected to the driven shaft 35 and the swash ring is supported by a universal joint 19 to shaft 18 and co-operates through a bearing 15 with a fixed plate 16 of adjustable inclination. The inclination of the plate 16 controls the swept volume of the motor 3 and therefore the operation of pump 2. When the plate is at right angles to the shaft 18 there is no flow of liquid and no torque transmitted and the pump block 5 will drive the casing 8 directly and transmit the drive to the driven shaft 35 through one of the ratio's 43, 37 or 44, 38. On inclining the plate 16, the motor 3 will transmit torque and allow the pump 2 to operate which will result in a slip of casing 8 with respect to the pump block 5 and a reduction in the speed transmitted to the driven shaft 35. The inclination of the plate of the pump 2 may also be variable if desirable to vary the swept volume thereof and the rate of supply to the motor 3. The ratio selecting sleeve 45 may be operated to engage gears 43 or 44 by a spring- loaded over-centre device and may be restored to a neutral position 'by a fluid pressure operated member engaging in groove 58. This said member may also act as a detent to hold shaft 39 and casing 8 stationary so that a reverse drive shaft 35 may be obtained by inclining the plate 16 of motor 3 in an opposite direction to that for forward drive.
