    摘要： A gearbox having a power take-off shaft for driving auxiliary machinery, and a gear selector arrangement by means of which the speed of rotation of the take-off shaft can be controlled. The take-off shaft has a terminal flange for connection to selected different splined adaptor shafts by means of which coupling to input shafts of different auxiliary machines may be effected and the gear selector mechanism is controlled by a rod housed in a bore in the take-off shaft and moved automatically to different positions by an axial projection on the splined adaptor shaft as the adaptor shaft is fixed in position so that the appropriate gear ratio for each splined adaptor shaft is automatically selected when the adaptor shafts are interchanged.

    摘要： A change speed device for power transmission, including, in one form, parallel input drive and output driven shafts, each having preferably a plurality of axially spaced, different diameter interengageable members preferably in the form of gears and forming part of the drive train, and for providing various drive speeds thereof. The input or drive gears are fixed to rotate with the input shaft at all times when it rotates, while the driven gears are mounted for idle rotation on the output shaft, responsive to intermeshed drive by the drive gears, and the driven gears are only selected normally one at a time to be interconnected or frictionally coupled to the output shaft to impart output rotation to the driven output shaft from the input drive shaft. A novel shifter device utilizing circumferentially spaced, axially directed, laterally notched, slide members to control roller or ball members which are carried in transverse grooves on the output shaft and interposed between the shaft and driven gears thereon, is embodied therewith to selectively align preselected notch portions of the laterally notched slide members with a predetermined one or set of the transverse grooves, to permit the rollers to move into said lateral notches where there the radial distance between the I.D. of the selected driven gear and the depth of the groove is lessened or less than the diameter or effective radial dimension of the roller or ball member, to thereby form a servo-type camming frictional interengaging or coupling action between the selected change-speed gear and the output shaft, responsive to continuing relative rotation of the drive and driven gears. When the notches and transverse grooves are non-aligned, a neutral condition exists for the power transmission. The shifter comprises separate circumferentially spaced notched slides which seat in or between complementally formed splines on the output shaft, which slides are collectively attached to and actuated by a common actuator collar and suitable linkage mechanism.

    摘要： A multi-stage change gear transmission having a main group of gear sets which can be made selectively effective and serially arranged therewith is a power flow stage consisting of parallel flow paths of respectively different transmission ratios and each including a friction clutch with the clutches adapted to be made alternately effective. The clutches provide for subdivision of the change in drive ratio when shifting from one gear set to the next. Also disclosed are control systems for controlling the gear sets and the friction clutches.
