Title: Transmissions
IPC: F16H47/04
Filed: 1972-11-29
Abstract: 1419104 Hydro-mechanical variable speed gear CLARK EQUIPMENT CO 29 Nov 1972 [9 Dec 1971] 55070/72 Heading F2D A variable-speed gear comprises an input shaft 14 and an output sun 16 which may be interconnected by a split-torque hydromechanical transmission or by a hydrostatic transmission 40, 44 alone to provide two variable speed ranges. The hydrostatic unit 40 drives a control shaft 22 on which is keyed a ring gear 62 and on which a planet carrier 52 and the sun 16 are freely rotatable. A coupling gear 76 may be moved axially by fluid pressure to engage external teeth 72 on the ring gear 62 thereby coupling the ring gear 62 to a gear 70 secured to the planet carrier to drive the output sun 16 by means of the hydrostatic unit 40 in a low speed range. When the speed of the gear 70 is synchronized with a coupling gear 86, driven by the input shaft 14 through gears 32, 34, 36, the gear 86 is moved axially by fluid pressure to couple the gears 32, 70 and the gears 62, 70 are decoupled, whereby the speed of the output sun 16 may be increased in a high speed range by decreasing the speed of the ring 62. To obtain reverse, the gear 70 is coupled to the gear 32 through a slidable coupling gear 98. In a second embodiment, Fig. 3 (not shown), a single axially slidable coupling gear is provided in association with a compound epicyclic transmission.
