Control device of the gearbox on the test bench of a propulsion motor -

摘要

The invention relates to a control device (2) for a gearbox controlled by a control lever and mounted on a test bench controlled by a computer connected to a test bench control rack (1) and a control processor (5) for the mechanical, hydraulic and electrical control means for the gearbox (4). Means (21) re provided for simulation of the commands for gearchanges, corresponding to the commands represented by the signals received in the control rack on transmitting signals to the processor (5), simulating the control or opening of contacts (46) to define the position of the lever (3) for control of the gearbox without acting on the gear lever (3) and without alteration to the gearbox software.
