TRANSMISSION TEST BENCH AND METHOD FOR OPERATING A TRANSMISSION TEST BENCH

摘要

The invention relates to a transmission test bench for two transmissions to be tested, comprising a mutual central shaft via which the two transmissions are coupled, having at least one drive motor for powering the transmissions, and having a load unit by way of which a tension between a drive side of one transmission and an output side of the other transmission is generated during the test operation, in particular by applying a difference in torque. Furthermore, means for a rotatory position change of at least one transmission are provided, which due to their array make it possible to change the rotatory relative positions of the transmissions relative to one another during the test operation. The invention further relates to a method for operating a transmission test bench, wherein during a test operation, a rotary position change of the transmissions relative to one another is carried out by way of the means for a rotatory position change.
