| 摘要 |
<p>The present invention concerns a dynamic test bench for measuring the torque and number of revolutions of endothermic engines, both Otto cycle and diesel, and electric motors, for recording the performance and simulating the dynamics of motion of vehicles on the road (inertia, aerodynamic friction and rolling resistance) by the application of suitable motor and braking torques to the shaft of the engine/motor being tested. The dynamic test bench according to the invention is of the type that provides for the use of an electric machine as motor and braking torque generator, the shaft of said endothermic engine or electric motor being linked to the rotor of said electric machine with means designed to transmit motor and braking torque from said endothermic engine or electric motor to said rotor of said electric machine and vice versa and is characterized in that said means designed to transmit motor and braking torque from said endothermic engine or electric motor (2) to said rotor (10, 21) of said electric machine (3, 20) and vice versa, comprise a rigid linkage between said motor shaft (6) and said rotor (10, 21), the case (8, 22) of said electric machine (3, 20) being rigidly linked to the structure (4) of said endothermic engine or electric motor (2).</p> |
