Abstract: 1474694 Change-speed gear; friction clutches VARIABLE KINETIC DRIVES Ltd 27 Aug 1974 [4 Sept 1973] 41542/73 Headings F2D and F2C In power transmission apparatus in which gear ratio changes are effected by engagement and disengagement of friction devices, at least one of the devices comprises two relatively movable members formed with interengaging cam projections so formed that when relative movement is applied between said members to effect initial engaging pressure between friction plates of the device the cam projections apply additional engaging pressure by means of relative rotation of said members when torque between said members is in one direction only. The apparatus described has a torque converter whose output shaft 38 drives the gearing through an input member 40 splined to the shaft 38 and carrying a power take-off gear 42 and a cylinder 43. Slidable within the cylinder is an annular piston 49 which carries a set of friction plates 53 interleaved with a set of friction plates 54 carried by a rotatable member 60 splined to a member 61 formed with sun gears 62, 63. The clutch constituted by these plates 53, 54 is engaged by fluid pressure admitted to a chamber 51 in opposition to diaphragm-type springs 52. A second clutch has plates 58, 59 carried by the cylinder 43 and an annular member 65 and is engaged, against springs 57 by fluid pressure admitted to a chamber 50 containing an annular piston 46. The member 65 also serves as carrier for planets 68 meshing with the sun gear 62 and has an extension 99 carrying friction plates 97 of a brake the other plates 96 of which are carried in a drum 95 coacting with a fixed piston 90. A ring gear 73 in mesh with the planets 68 serves as carrier for planets 70 meshing with the sun gear 63 and is directly connected to the output shaft 69. A ring gear 74 meshing with the planets 70 is connected with a multi-plate friction brake 76, 77 having a drum 78 coacting with a fixed piston 79. The two brakes are released by springs 82, 100 and applied by pressure fluid applied to chambers 81, 98. With the brake 76, 77 applied first and second ratios are established by engagement of clutches 53, 54 and 58, 59, respectively. Third ratio requires release of the brake and engagement of both clutches, whilst reverse is established by application of the brake 96, 97 and engagement of clutch 53, 54. The cam projections for applying torque dependent engaging pressure are associated with the clutch 53, 54 and both brakes. In the case of the clutch such projections comprise teeth 55 on the piston 49 co-operating with teeth 56, Fig. 2, on the member 40. Similar cam projections are provided for each brake, e.g. at 83 for the brake 76, 77.
