Test bed for testing two identical gear boxes in automotive industry, has case connected to frame, and input shaft of gear box with brake or blocking unit arranged with frame, and input shaft of another gear box driven in rotation by motor

摘要

The test bed has a differential unit (Diff A) e.g. epicyclic gear, that is arranged for connecting an input shaft of a gear box (BV1). The input shaft is blocked against rotation by a blocking unit (A2). Another differential unit (Diff C) is arranged for connecting a set of output shafts of the gear boxes (BV1, BV2). A case is connected to a frame of the test bed by a deformable flexible connection. The input shaft is provided with a brake or another blocking unit (A1) arranged with the frame. An input shaft of another gear box is driven in rotation by a motor (A). An independent claim is also included for a method for manufacturing a test bed.
