Transmission testing device on load test bed, especially for commercial vehicle and construction and processing machinery

摘要

The device has a drive motor, a test transmission, a transmission after the test transmission for adaptation to the load machine's characteristics and at least one load machine. Two load machines (8,10), which are differently and separately controllable, can be combined in parallel in a transmission (4) to divide or sum the power. The transmission for both load machines is a planetary transmission (4) with one load machine connected to its solar wheel (5) and the other connected to its hollow wheel (7). The rotation masses acting on the test transmission (3) are varied during machine speed regulation.
