Patent ID: 8635904

Claim:
A torque-application test stand for transmissions, comprising: a drive motor; a drive motor drive shaft adjoined to the drive motor and having at least one mechanical interface for connection to a first drive shaft or first output shaft of a first transmission; a balance shaft having at least two mechanical interfaces for one of a connection between the first output shaft and a second output shaft of a second transmission, and a connection between the first drive shaft and a second drive shaft of the second transmission; a test stand output shaft having at least one mechanical interface for connection to the second drive shaft or the second output shaft of the second transmission; a circulating tensioning device connected with a positive fit to at least a first, a second and a third planetary gear; a first fixed station and a second fixed station, the first fixed station and the second fixed station having respective shafts mounted therein respectively rotationally engaged with the first stand and second planetary gears, the shaft mounted in the first fixed station comprising the drive motor drive shaft; a third station movable between the first fixed station and the second fixed station in or against a direction of circulation of the tensioning device, a shaft which is rotationally engaged with the third planetary gear being mounted in the third station, the shaft mounted in the third station comprising the test stand output shaft; wherein the drive motor drive shaft, the first transmission, the balance shaft, the second transmission, the test stand output shaft and the tensioning device form a closed drive circuit.
