The invention relates to a gear shifting point (10) for producing a rotationally fixed connection between a toothed wheel (16, 18) and a shaft (12). Said gear shifting point (10) comprises a shaft (12), a sliding sleeve (24) and at least one toothed wheel (16, 18). The toothed wheel (16, 18) is mounted rotationally with respect to the shaft (12). The sliding sleeve (24) is mounted on the shaft (12) in such a way that it is not rotatable therewith. The toothed wheel (16, 18) and the sliding sleeve (24) are embodied in such a way that a rotationally fixed connection can be produced therebetween in the coupled state of the gear shifting point (10) and no connection can be produced between the toothed wheel (16, 18) and the sliding sleeve (24) in the neutral state of the gear shifting point (10). The aim of said invention is to develop and improve the gear shifting point (10) which is used for producing a rotationally fixed connection between the toothed wheel (16, 18) and the shaft (12), is cost effective and operates in as interference-free manner as possible. For this purpose, the inventive gear shifting point (10) is characterised in that the sliding sleeve (24) is provided with at least one electromagnet (38, 40) and the coupled state of the gear shifting point (10) is obtainable by activating said electromagnet (38, 40).
Gear shifting point for the establishment of a connection, fixed against rotation, between a gear (16, 18) and a shaft (12), with a shaft (12), a shift sleeve (24) and at least one gear (16, 18), where the at least one gear (16, 18) is supported in bearings, free to rotate relative to the shaft(12), where the shift sleeve (24) is supported in bearings, fixed against rotation on the shaft (12), and where the gear (16, 18) and the shift sleeve (24) are configured in such a way that a connection, fixed against rotation, can be established in a shifted condition of the gear shifting point (10) between the gear (16, 18) and the shift sleeve (24) and that in a neutral condition of the gear shifting point (10) no connection, fixed against rotation, can be established between the gear (16, 16)*2 and the shift sleeve (24), characterized by the shift sleeve (24) that is equipped with at least one electromagnet (38, 40), and that a shifted condition of the gear shifting point (10) can be established upon activation of the electromagnet (38, 40).
