| 摘要 |
The invention relates to a hydrodynamic machine, particularly a hydrodynamic retarder, comprising a housing in which at least one shaft (19), two blade wheels, particularly a rotor (1) and a stator (2) that form a toroidal working chamber able to be filled with a working medium, and a step-up gear (5) are arranged, at least one blade wheel (1) and said step-up gear (5) being arranged about a common rotational axis (28) and being mounted such that they can rotate independently of one another. In order to improve safety during operation, it is suggested that a coupling device (6, 7, 11, 12, 13, 14, 15, 21) is provided to transmit torque between the step-up gear (5) and the blade wheel, rotor (1), said coupling device being arranged in the housing (3, 4) of said hydrodynamic machine. |
