Abstract

1,181,526. Variable speed gearing. IFA GETRIEBEWERKE BRANDENBURG VEB. 9 Aug., 1967, No. 36559/67. Heading F2D. A split-torque variable-speed gear for a tractor comprises an input shaft 2, a continuously variable ratio hydrostatic transmission 6 in parallel with a stepped ratio change-speed gear, and a sun-planet-annulus epicyclic train 16, 19, 17 to combine the parallel path outputs to drive the input bevel pinion 40 of a differential gear (not shown). A power take-off shaft 24 is driven from the input shaft 2 via gears 3, 4, a hollow shaft 5, and gears 8, 9, 25. In Fig. 1, the input shaft 2 is driven through a starting clutch 1. The hollow shaft 5 and a shaft 15 extending therethrough respectively form the input and output of the hydrostatic drive 6, the shaft 15 carrying the sun 16 of the output epicyclic train. The gear 9 is connected to a shaft 7 by a one-way clutch (not shown), and a gear 10 secured to shaft 7 meshes a gear 11 rigid with the annulus gear 17 and clutchable to the shaft 5 by a disc or one-way clutch 14. A gear 12 meshing the gear 11 is clutchable to the input shaft 2 by a clutch 13. For mechanical reverse, a dog clutch 23 is engaged to drive the bevel gear 40 from the power take-off shaft 25 via gears 21, 20. For forward drive, a dog clutch 22 is engaged to connect the planet carrier 19 to the bevel gear 40. To start from rest, the hydrostatic drive is set to lock the sun 16, and clutch 1 is engaged, the drive being via gears 3, 4, 8, 9, 10, 11, to the annulus gear 17. When clutch 1 is fully engaged the hydrostatic drive is adjusted to progressively accelerate the sun 16 in the same direction as the annulus 17. For the second speed range, clutch 14 is engaged and the one-way clutch of gear 9 over-runs, the annulus 17 being driven directly from the shaft 5. For the third speed range, clutch 14 is disengaged and clutch 13 engaged so that annulus 17 is driven via gears 12, 11. In Fig. 2, a planetary change speed gear is used. Stepped planets 36 in a carrier 34 rigid with the gear 11 mesh an annulus gear 35, an input sun 33 on shaft 5, and a reaction sun 37 held by a brake 39 for reverse. To start from rest, a brake 38 is engaged to hold the annulus 35, and the hydrostatic drive is set to lock the sun 16, drive being via gears 3, 4, 33, planet carrier 34, and annulus 17. Then the sun 16 is accelerated by adjusting the hydrostatic drive. For the second speed range, brake 38 is released and clutch 14 is engaged so that annulus 17 is driven from the hollow shaft 5. For the third speed range, clutch 14 is disengaged and clutch 13 engaged so that annulus 17 is driven via gears 12, 11. The hydrostatic transmission 6 has a pump G and a motor M having their respective swashplates connected to the input and output shafts respectively.
