- the invention is based in particular on the object of increasing the design scope of a generic switching device and thereby achieving space-saving potential. It is solved according to the invention by the features of claim 1. Further configurations result from the subclaims and subclaims.
- the invention is based on a switching device, in particular for a motor vehicle transmission, with a sliding sleeve arranged on a first shaft, which can be brought into operative connection with at least one corresponding coupling body and is limited in its displacement movement by at least one stop.
- the stop be formed by a component to which the sliding sleeve is in its stop position. tion has a relative movement in operation.
- the constructive design freedom can be increased, additional components for forming a stop can be avoided, and space-saving potentials in the radial and in the axial direction can be created.
- Recesses and / or elevations on the sliding sleeve and / or on a synchronizing body can be avoided, the manufacturing effort can be reduced and the component strength can be increased.
- the component forming the stop can be formed by various components which appear useful to the person skilled in the art, such as, for example, a housing part or advantageously a component coupled to a second shaft, such as, in particular, a counter gear to a gear to be switched.
- a gearwheel to be shifted with a sliding sleeve has a smaller diameter than the sliding sleeve of the shifting device in a shifting device.
- the component forming the stop has at least one separately designed stop surface, wobbling movements in the stop position can be at least largely avoided and wear can be reduced.
- stop surface is formed by a molded-on elevation, this can be produced inexpensively and large-scale reworking can be avoided.
- an abutment surface of the sliding sleeve be arranged in a region deviating from the tips of a sliding sleeve toothing. Wear of the tips due to the relative movement of the sliding sleeve relative to the component forming the stop can be avoided.
- the stop surface is advantageous in the radially outer region of the tips, starting from the Impact-forming component for the sliding sleeve arranged in front of the tips.
- the switching device comprises a resetting unit which, during operation, guides the sliding sleeve from its stop position into an end position spaced from the stop. In the end position, the resetting unit can thereby prevent friction between the sliding sleeve and the component forming the stop, and the resulting noise and vibration transmission can be avoided.
- the resetting unit has a bevel which generates a resetting force in a resetting process
- the resetting unit can be implemented in a particularly cost-effective and space-saving manner. Additional components, assembly effort and costs can be saved, in particular if the bevel is integrally formed on the sliding sleeve, for example if this is advantageously formed by a run-out slope of a deposit of the sliding sleeve.
- the resetting unit could also be formed by other spring, centrifugal force and / or mechanisms based on magnetic forces that appear to be useful to the person skilled in the art.
- the bevel has an angle of less than or equal to 15 °, an advantageous restoring force can be achieved and, in addition, undesired forces of a synchronizer ring on the sliding sleeve and undesired vibrations can be at least largely avoided.
