Embodiment Construction

[0019] according to figure 1 and image 3 The transmission 1 according to the invention has at least one shaft 2 on which a guide sleeve 4 with a first external toothing 3 is arranged in a rotationally fixed manner. Also arranged on the shaft 2 is a coupling element 7 with a second external toothing 5 . The second external tooth structure 5 can also be arranged directly on the idler gear 6 . Furthermore, the transmission 1 according to the invention has a sliding sleeve 9 which is displaceable in the axial direction of the shaft 2 and has an internal toothing 8 , wherein the sliding sleeve 9 can be connected in a decoupled position to a It is set between a coupled position in which the internal toothing 8 is not operatively connected to the second external toothing 5 and a coupled position in which the internal toothing 8 meshes with the second external toothing 5 . according to image 3 , where the decoupled position is shown. According to the invention, the inner toothi...

Abstract

A transmission having at least one shaft, on which a guide sleeve which has a first external toothing system is arranged fixedly so as to rotate with it and at least one slider sleeve which has an internal toothing system is arranged, it being possible to adjust the slider sleeve between a disengaged position, in which the internal toothing system and a second external toothing system on a clutch element are not operatively connected, and an engaged position, in which the internal toothing system meshes with the second external toothing system. The internal toothing system and / or the first external toothing system are / is configured in such a way that there is merely punctiform contact between them in the engaged position. As a result, in particular, an undesired gear disengagement can be suppressed.

Description

technical field [0001] The invention relates to a transmission with at least one shaft according to the preamble of claim 1 . Background technique [0002] DE 744 949 has disclosed a transmission of this type with at least one shaft on which a guide sleeve with a first external toothing is rotatably provided and at least one with a second Idle gear with external tooth structure. Furthermore, at least one sliding sleeve is provided which is displaceable in the axial direction of the shaft and has an internal toothing, wherein the sliding sleeve and the guide sleeve are formed in the manner of a toothed coupling. [0003] DE 1 500 326 has likewise disclosed a tooth coupling of this kind for a transmission. In order to be able to ensure improved safety against undesired disengagement of the coupled coupling element, only the tooth flank edges of the teeth of the sliding sleeve in the torque-transmitting engaged position are in contact with the flanks of the outer toothing of ...
