Abstract
Official abstract text for this publication.
A drive includes at least one motor with a drive shaft and at least one output shaft which is in particular mechanically connected to a gear. The drive shaft and the output shaft are aligned substantially axially. The drive shaft and the output shaft each have a coupling portion through which a torque can be transmitted from the drive shaft to the output shaft by mechanical coupling. Each coupling portion is connected to the shaft thereof for rotation therewith and the coupling portions can be mechanically coupled by being axially plugged together.
First claim
Opening claim text (preview).
The invention claimed is: 1. A drive, comprising: at least one traction motor having a drive shaft; at least one output shaft; a gear connected to said at least one output shaft; said drive shaft and said at least one output shaft being substantially axially aligned; a first coupling portion associated with said drive shaft and a second coupling portion associated with said output shaft, said coupling portions configured to be mechanically coupled to each other by being axially plugged together; said drive shaft being connected to said first coupling shaft and said at least one output shaft being connected to said second coupling shaft in a rotatably fixed manner for transmitting a torque from said drive shaft to said at least one output shaft by mechanical coupling; and a sealing element fastened on said second coupling portion and a counter element formed on said first coupling portion, said sealing element being shaped to form a labyrinth seal by being axially plugged together with said counter element formed on said first coupling portion. 2. The drive according to claim 1 , wherein said gear is mechanically connected to said at least one output shaft. 3. The drive according to claim 1 , wherein said coupling portions configured to be axially plugged together are parts of a spherical tooth coupling, and said coupling portions have teeth. 4. The drive according to claim 3 , wherein said spherical tooth coupling is configured to be sealed by said coupling portions.
