1. A preassembled traction mechanism drive, comprising at least two drive wheels around which an endless traction mechanism is wrapped, anda tensioning device that has a housing and is supported on the internal side of the endless traction mechanism,at least two fixation elements are provided on the housing that are fixedly connected to the housing and that fix the drive wheels, around which the endless traction mechanism are wrapped, in a defined assembly position at an operating distance from one another, wherein an axial displacement of the at least two fixation elements releases the fixed drive wheels. 2. The preassembled traction mechanism drive as recited in claim 1, wherein the fixation elements are located on the housing such that an axial displacement of the housing during installation of the tensioning device causes a release of the fixed drive wheels. 3. A preassembled traction mechanism drive, comprising at least two drive wheels around which an endless traction mechanism is wrapped, anda tensioning device that has a housing and is supported on the internal side of the endless traction mechanism,at least two fixation elements are provided on the housing that are fixedly connected to the housing and that fix the drive wheels, around which the endless traction mechanism are wrapped, at an operating distance from one another, wherein the fixation elements are located on the housing such that during installation of the tensioning device the fixation elements are moved out of a plane spanned by the fixed drive wheels and thus release the drive wheels. 4. The preassembled traction mechanism drive as recited in claim 1, wherein the tensioning device is situated between the drive wheels, and at least two of the drive wheels are fixed relative to one another by simultaneous contact with the fixation elements of the tensioning device. 5. The preassembled traction mechanism drive as recited in claim 4, wherein the endless traction mechanism is pre-tensioned by the tensioning device, and the drive wheels are tensioned against the tensioning device by a tension force acting in the endless traction mechanism. 6. The preassembled traction mechanism drive as recited in claim 1, wherein the housing of the tensioning device has four of the fixation elements and there are two of the drive wheels, and the four fixation elements fix the two drive wheels in an assembly position relative to one another. 7. The preassembled traction mechanism drive as recited in claim 1, wherein the housing and the fixation elements are formed in one piece. 8. The preassembled traction mechanism drive as recited in claim 1, wherein the housing of the tensioning device is comprised of an aluminum cast part. 9. The preassembled traction mechanism drive as recited in claim 3, wherein an axial releasing movement of the housing with fixation elements, which movement releases the fixing of the drive wheels, is included in a movement executed by the tensioning device during installation. 10. A preassembled traction mechanism drive, comprising at least two drive wheels around which an endless traction mechanism is wrapped, anda tensioning device that has a housing and is supported on the internal side of the endless traction mechanism,at least two fixation elements are provided on the housing that are fixedly connected to the housing and that fix the drive wheels, around which the endless traction mechanism are wrapped, at an operating distance from one another, wherein the drive wheels have teeth and the fixation elements are at least partly comprise engagement elements that fix the drive wheels in a defined assembly position relative to one another by engagement in the teeth.
