DETAILED DESCRIPTION

[0031] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description.

[0032] FIG. 1 shows a system having a manual transmission 100 and a coupling arrangement according to an embodiment of the present disclosure in a first gear selection position. The coupling arrangement couples a gearshift 110 and a shift operator 120 with a selector shaft 130 for the manual transmission 100.

[0033] For this purpose, the coupling arrangement has a transmission member with a gearshift-side first section in the form of a first rod 1, a selector shaft-side second section in the form of a second rod 2 and a connecting section connecting them in the form of an articulated chain 3 and a guide in the form of a channel 21 angled at 90 with a deflection element 22, by which the transmission member 1-3 is displaceably mounted and deflected by 90. The guide 21, 22 is supported in a selector shaft-side abutment 30 which is attached to a base 60, on which the gearshift 110 is mounted articulated.

[0034] An interface 11 of the first section 1 is connected to a lever arm 111 (see FIG. 2) of the gearshift 110 in a joint 40 non-destructively detachably connected. An interface 12 of the second section 2 is connected to a cable 50 of a Bowden cable or in a modification with a switch rod of a shift linkage for actuating the inner shift operator 120 or the selector shaft 130.

[0035] As seen by the sequence illustrated from FIG. 2 to FIG. 1 and the movement arrows indicate in FIG. 2, the coupling arrangement implements a gear pre-selection or selection operating movement of the gearshift 110 and an accompanying pulling out movement of the first section 1 further out of the guide 21 in a pulling away movement of the Bowden cable 50 or the switch rod from the selector shaft 100 or shift operator 120 to the right in FIG. 2, and vice versa (see FIG. 1 to FIG. 2 and movement arrows in FIG. 1) an opposing gear pre-selection or selection operating movement of the gearshift 110 or an accompanying insertion of the first section 1 deeper in the guide 21 in a pushing movement of the Bowden cable 50 or the switch rod to the selector shaft 100 or shift operator 120 to the left.

[0036] In another embodiment, shown in FIG. 3, which otherwise corresponds to the embodiment of FIGS. 1 and 2 and to which reference is therefore made to the description thereof, the coupling arrangement conversely implements a pulling out movement of the first section 1 further out of the guide 21 in a pushing movement of the cable 50 or the switch rod to the selector shaft 100 or shift operator 120 to the left, and vice versa (see movement arrows in FIG. 3) an insertion movement of the first section 1 deeper into the guide 21 in a pushing movement of the cable 50 or the switch rod to the selector shaft 100 or shift operator 120 to the left.

[0037] FIG. 4 shows in FIG. 1 corresponding representation of a system having a coupling arrangement according to a further embodiment of the present disclosure in a first gear selection position. Corresponding features are again identified by identical reference numerals, so that reference is made to the preceding description of the embodiments of FIGS. 1-3 and only differences are discussed in the following.

[0038] In the embodiment of FIG. 4, as indicated by rotation arrows, the gearshift 110 is mounted in a universal joint on the base 60 by its lever arm, to which the interface 11 of the first section 1 is connected in the joint 40 non-destructively detachably, to the explanation of which reference is additionally made to the already mentioned DE 10 2016 201 551 A1. By the movement of the gearshift 110 or its shaft 112, as indicated by the rotation arrows, a gear can again be selected, a gear is engaged or released by a pivoting movement perpendicular thereto about the longitudinal axis of the lever arm.

[0039] FIG. 5 shows a perspective view of part of a system having a coupling arrangement according to a further embodiment of the present disclosure. Corresponding features are again identified by identical reference numerals, so that reference is made to the preceding description of the embodiments of FIGS. 1-4 and only differences are discussed in the following.

[0040] In the embodiment of FIG. 5, the gearshift 110 is likewise mounted in a universal joint on the base 60 by its lever arm 111, with which the interface 11 of the first section 1 in the joint 40 is non-destructively detachably connected. A gear can in turn be selected by the movement of the gearshift 110 or its shaft 112 or with this rotating lever arm 111 indicated by the rotary arrow.

[0041] Although exemplary embodiments have been explained in the foregoing description, it should be understood that a plurality of modifications is possible. Thus, in particular also in the embodiment with universal joint bearing of FIG. 4, the coupling arrangement implements a pulling out movement of the first section 1 further from the guide 21 in a pushing movement of the cable 50 or the switch rod to the selector shaft 100 or shift operator 120 to the left as explained with reference to FIG. 3.

[0042] While at least one exemplary embodiment has been presented in the foregoing detailed description, it should be appreciated that a vast number of variations exist. It should also be appreciated that the exemplary embodiment or exemplary embodiments are only examples, and are not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the foregoing detailed description will provide those skilled in the art with a convenient road map for implementing an exemplary embodiment as contemplated herein. It should be understood that various changes may be made in the function and arrangement of elements described in an exemplary embodiment without departing from the scope of the invention as set forth in the appended claims.
