Abstract: A method for controlling operational sequencing of gears in an automatic transmission (102) which has been built in an auxiliary mode. In the case of such a shifting transmission it is possible that during the engagement of its transmission gear stage, impact noises or contact noises are present in the shifting procedure. This can occur by the generation of a tooth-on-tooth positioning between the toothing of a sliding collar (126) and the come-along toothing of an idler gear (130, 132). Provision is made for the control of the activation movement of the sliding collar (126) carried out in such a manner that an activation condition impact of the transmission parts, which are partakers in the shifting associated transmission part onto other transmission parts with the least possible impact force and/or with a least possible impact noise level.

Abstract translation: 一种用于控制在辅助模式中构建的自动变速器（102）中的齿轮的操作顺序的方法。 在这种变速传动装置的情况下，在传动齿轮级的啮合过程中可能存在冲击噪音或接触噪声。 这可以通过在滑动轴环（126）的齿部与惰轮（130,132）的往复齿之间产生齿 - 齿定位来进行。 这样做是为了控制滑动轴环（126）的启动运动，以使传动部件的激活状态受到影响，传动部件是将相关联的变速器部件转移到其他传动部件上的可能性最小 冲击力和/或具有尽可能低的冲击噪音水平。

Abstract: The invention relates to a change-under-load transmission having an input shaft (1) and an output shaft (6), each carrying a pair of gearwheels (2, 3; 4, 5). A composite layshaft comprises two pairs of coaxial shafts (7, 8; 9, 10) which are aligned axially with one another. At their adjacent ends the shafts carry friction coupling elements (25, 31 and 25, 30) which have effective coupling faces (25', 31'; 26' 30'). At their remote ends each of the coaxial shafts carries a gearwheel (23, 27; 24, 28) which is in permanent mesh with an associated one of the gear wheels on the respective input or output shaft. Between the adjacent ends of the two pairs of coaxial shafts a central friction coupling element (32) is positioned so as to be freely slidable axially with respect to the coaxial shafts. Correspondingly positioned ones (7, 9 in FIG. 1; 8, 10 in FIG. 2) of the two pairs of shafts are supported so as to be axially inwardly slidable independently of one another out of a rest position into which they are biassed by springs (21, 22 in FIG. 1; 45, 46 in FIG. 2), and the other shaft (8, 10 in FIG. 1; 7, 9 in FIG. 2) are axially immovable. In the rest position of the shafts the effective coupling faces (30' 31' in FIG. 1, 47' 48' in FIG. 2) of the coupling elements on the slidable shafts are nearer the central coupling disc than the coupling faces (25' 26' in FIG. 1 and 49', 50' in FIG. 2) of the coupling elements on the axially immovable shafts.
