Abstract

1443437 Variable-speed gear CHRYSLER UNITED KINGDOM Ltd 21 Dec 1973 [7 Feb 1973] 6112/73 Heading F2D A gear-box has parallel input, intermediate and output shafts 11, 17, 24 with a plurality of selectively synchronizable and couplable constant mesh trains to provide a plurality of ratios and a chain drive between two sprockets 15, 26 on the input and output shafts one of which sprockets is rotatable on its shaft and couplable therewith by synchronizing means to provide a further drive between the input and output shafts. A synchronizer 18 is movable to couple a wheel 19 to the shaft 17 to provide first ratio through wheels 12, 16 fixed to the shafts 11, 17, the wheel 19 and a wheel 22 fixed to the output shaft. Engagement of the synchronizer 18 with a wheel 20 establishes second ratio through the wheels 12, 16, 20 and a wheel 23 fixed to the output shaft. With the synchronizer 18 in neutral position, a synchronizer 13 may couple a wheel 14 to the input shaft so that third ratio is established through the wheels 14, 20, 23, or it may couple the sprocket 15 with the input shaft to establish high ratio through the chain, e.g. an inverted tooth chain, and sprockets 15, 26. High ratio may be 1 : 1 or higher, e.g. the sprockets 15, 26 may have 29 and 28 teeth, respectively. The wheel 22 may be free on the shaft 24 and connectible thereto by a further synchronizer coupled with the synchronizer 13 so that it is uncoupled from its shaft only when the synchronizer 13 is in position for high ratio. A further wheel (not shown) may be movable into engagement with wheels 21, 25 fixed to the shafts 17, 24 for reverse ratio. Alternatively the further wheel may be fixed and in constant mesh with the wheel 21, and the wheel 25 may be slidable into engagement with it. Oil picked up by the chain from the bottom of the gear-box is flung into channels (not shown) leading to a passageway 32 for lubricating the bearings of the wheels 19, 20.
