ABSTRACT:
A transmission comprising gear case bottom part 72 and rear cover 73; shaft 19 supported on bearings 34 and 37; shaft 20 supported on bearings 33, 38 and 39; shaft 21 supported on bearings 35, 36 and 40 and shaft 22 supported on bearings 41 and 42.
Shaft 19 carries a cluster of seven gears 1, 2, 3, 4, 5, 6 and 7 all of them being integral part of the shaft. These gears are positioned along the shaft from the smallest gear 1 to the largest gear 7. Each gear on shaft 19 is permanently meshed with a gear on either shaft 20 or shaft 21. Gear 1 is meshed with gear 8, gear 2 with gear 9, gear 3 with gear 10, gear 4 with gear 11, gear 5 with gear 12, gear 6 with gear 13 and gear 7 with gear 14. Gear 17 on shaft 21 and gear 18 on shaft 20 are meshed with gear 16 on the output shaft 22. All gears on shafts 20, 21 and 22 in FIG. 1 and gear 65 on shaft 61 in FIG. 2 are rotating on angular contact ball bearings with their inner rings fixed to the shafts. Gears are selected using cone or multiple plate disk clutches driven by hydraulic actuators.
