Abstract
1431160 Change-speed gear CLARK EQUIPMENT CO 27 Aug 1974 [27 Aug 1973] 37416/74 Heading F2D A transmission providing three or four forward ratios and a corresponding number of reverse ratios comprises a system of constant mesh gears and clutches arranged on several shafts all lying in a common plane. In the arrangement shown in Fig. 2 the first forward ratio is established by engagement of fluidactuated multi-plate clutches 38, 64 so that drive is transmitted from the input shaft 14 to the output shaft 16 through gears 52, 54, 68, 70, 62, 66, 74, 76. Engagement of clutch 58, instead of 64, establishes second ratio through gears 52, 54, 66, 74, 76, and clutch 72 establishes third ratio, with clutches 64, 58 released, through gears 52, 54, 68, 74, 76. On release of the clutch 38 and engagement of the clutch 50 the three reverse ratios are similarly established by selective engagement of the clutches 64, 58, 72. The shaft 16 and gear 76 may be omitted, in which case the output is taken from the shaft 22. In a modification (Fig. 3, not shown) the clutch 72 is omitted, and a shaft (83) coaxial with the shaft 20 carries a gear in mesh with the gear 66, and two further gears in mesh with gears freely rotatable on the output shaft and clutchable thereto by a dog clutch. This arrangement provides four forward and reverse ratios. In a further three-ratio arrangement (Fig. 5, not shown) the gear 68 is omitted, and a gear in mesh with the gear 62 is fixed on the shaft 18. Again, the output may be taken from the shaft 22. In a modification with coaxial input and output shafts 14, 132, Fig. 8, three forward ratios are established by clutches 64, 58, 136 and forward or reverse by clutches 38, 50. Fig. 9 illustrates a modification of this arrangement in which the input and output shafts are not coaxial. As indicated in Fig. 2 the shaft 16 may provide two outputs, and one of these may be disconnectible by a sliding-tooth clutch. Also, in any of the embodiments the final drive wheel may be disconnectible from its output shaft, and a power take-off shaft may be provided, e.g. connected to the input shaft.
