Description

The present invention relates to a transmission, in particular a motor vehicle transmission, and a method for operating the transmission.

An object of an embodiment of the present invention is to improve a transmission or its operation.

This object is achieved by a transmission having the features of claim 1. Claims 10, 11 protect a motor vehicle with a transmission described here or a method for operating a transmission described here. Advantageous embodiments of the invention are the subject matter of the dependent claims.

According to one embodiment of the present invention, a transmission has a pinion which is rotatable about an axis and displaceable along it, in one embodiment rotatable and displaceable. This pinion and axle are referred to herein as the first pinion and first axle, respectively. In general, a designation as "first", "second", "third" etc. does not mean any restriction of generality in the present case, but only serves to identify or differentiate.

According to one embodiment of the present invention, a transmission has a disk that can be rotated about a second axis and is rotatably mounted in one embodiment.

In one embodiment, the first and second axes are transverse to one another; in one embodiment, they form an angle with one another that is at least 60° and/or at most 120°, preferably 90°. In one embodiment, the first and second axes intersect, in another embodiment they are skew to one another.

• - when the first pinion is arranged in a first position along the first axis, this first position being associated with the first circular path of the first face, disc and first pinion, preferably permanently, via or through engaging in the recesses of the first pinion(s ) Elevations on the first circular path of the first face are coupled in a form-fitting manner; and

Since the depression slides along the (respective) guide in a form-fitting manner, in one embodiment it is possible in a particularly advantageous manner to shift gears or change the gear ratio without interrupting the transmission of force or torque or without interrupting the traction force. In one embodiment, this can shorten a shifting process and/or reduce power losses, weight and/or component count and/or complexity.

In one embodiment, a plurality of elevations are (each) arranged on the first end face of the disk on one or more third circular paths which are concentric to the first circular path of the first end face and have different diameters from the first and second circular paths and from one another in such a way that during a rotation of the first pinion about the first Axis and the disc around the second axis Disc and first pinion when the first pinion is arranged in one of the (respective) third position along the first axis assigned to this or the respective third circular path of the first end face via elevations on this or The respective third circular path of the first end face are coupled in a form-fitting manner, with one or more guides being arranged on the first end side of the disc, which (each) create a depression in the first pinion between an engagement with an elevation on this or the respective third circular path of the first face and one of the elevations on another, in one embodiment the first or second or another third, the circular paths of the first face, in one embodiment reversibly, form-fittingly transfer, with this depression sliding along on the (respective) guide , or is/are the guide(s) for this established or is/are used for this purpose.

In an analogous manner, one or more third circular paths with elevations of the same contour can also be provided, with one of the elevations 22.3 only being indicated here for a third circular path K3 for the sake of clarity.

A plurality of indentations 11 are arranged on an outer circumference of first pinion 10 in such a way that during rotation of first pinion 10 about first axis A1 and disk 20 about second axis A2, disk 20 and first pinion 10 are in one of the first circular paths K1 of the first pinion 10 assigned to the first end face 21 arranged along the first axis A1 via elevations 22.1 engaging in the depressions 11 of the first pinion 10 on the first circular path K1 of the first end face 21 and in one of the second circular path K2 of the first end face 21 associated second position along the first axis A1 arranged first pinion 10 are coupled in a form-fitting manner in the depressions 11 of the first pinion 10 engaging elevations 22.2 on the second circular path K2 of the first end face 21. This is the same for the third circular path(s) K3.

On the first end face 21 of the disk 20 is at least one guide 22 for positive locking Transfer of a depression 11 of the first pinion 10 between an engagement with an elevation 22.1 on the first circular path K1 of the first end face 21 and an engagement with an elevation 22.2 on the second circular path K2 of the first end face 21 arranged on which this depression 11 during this transfer glides along. The shape of this guide 22 is only to be understood schematically and can be determined, in particular optimized, for example by simulation or the like. This also applies equally to the shape of the depressions 11 and the placement of the elevations 22.1, 22.2 and the dimensions etc.. At least one guide 22' is provided analogously for the third circular path(s) K3.

In the embodiment shown in solid lines, the disk 20 is connected in a rotationally fixed manner to a transmission input or output shaft 23 and the first pinion 10 is arranged in a rotationally fixed manner on a first shaft 12 and is displaceable along the first axis A1.

The functioning or the interaction of the first pinion 10 and the first end face 21 and of the second pinion 100 and the second end face 24 is analogous, so that reference is made to the corresponding description. Correspondingly, the second pinion 100 is arranged in a rotationally fixed manner on a second shaft 120 and can be displaced along the third axis A3.

The transmission also has a controller 3 for controlling the first actuator 13 for displacing the first pinion 10 along the first axis A1 and in the in 1 dashed line modification for controlling the second actuator 130 to move the second pinion 100 along the third axis A3, based on signals from the sensors S1, S2 and optionally S3.

The disk 20 has a free surface F1 on the first end face 21 such that when the first pinion 10 is arranged in a position associated with the free surface F1 of the first end side 21 along the first axis A1, the disk 20 and the first pinion 10 are not coupled in a form-fitting manner, and in the in 1 shown in dashed lines, on the second end face 24 a free surface F2 such that when the second pinion 100 is arranged in a position associated with the free surface F2 of the second end face 24 along the third axis A3, the disk 20 and the second pinion 100 are not positively coupled.

To operate the transmission, the controller 3 commands the first actuator 13 to shift the first pinion 10 to change from one gear ratio to another along the first axis A1 from the first to the second position on the first shaft 12 in such a way that a depression 11 of the first pinion 10 is positioned between engagement with an elevation 22.1 on the first circular path K1 of the first end face 21 and engagement with an elevation 22.2 is transferred to the second circular path K2 of the first end face 21 and in the process slides along the guide 22 of the first end face 21 of the disk 20, as in 4 indicated by a motion double file.

To change from this translation to another translation, the controller 3 commands the first actuator 13 to shift the first pinion 10 along the first axis A1 from the second to a third position on the first shaft 12 associated with the third circular path K3 in such a way that a depression 11 of the first pinion 10 is transferred between an engagement with an elevation 22.2 on the first circular path K1 of the first end face 21 and an engagement with an elevation 22.3 on the third circular path K3 of the first end face 21 and thereby on the guide 22' of the first Face 21 of the disc 20 slides along, as in 4 analogously indicated by a motion double file.

in the in 1 In a modification shown in dashed lines, the controller 3 can use the second actuator 130 to shift the second pinion 100 along the third axis A3 from the first to the second position on the second shaft 120 in order to change from one gear ratio to another gear ratio in such a way that a recess 110 of the second pinion 100 is transferred between an engagement with an elevation 25.1 on the first circular path k1 of the second end face 24 and an engagement with an elevation 25.2 on the second circular path k2 of the second end face 24 and in doing so on the guide 25 of the second end face 24 of the Disc 20 slides along, command, as in 4 analogously indicated by the motion double file.

To prevent power transmission, the controller 3 can use the first actuator 13 to move the first pinion 10 along the first axis A1 into the position assigned to the free surface F1 of the first end face 21 and into the in 1 additionally or alternatively move the second pinion 100 along the third axis A3 into the position associated with the flank F2 of the second end face 24.

The respective displacement of the first or second pinion 10, 100 is synchronized with an angular position of the disk 20 detected by the sensor S2 and its change.

By moving it in the opposite direction, the power transmission can be restored or the translations can be reversed or changed back.
