摘要： A drive train assembly (10) for an automotive fan (12) which includes a hydraulic coupler (22) that dynamically interconnects a fan blade shaft (24) to a driving shaft (18) within a range of radial offsets to permit reduction of clearance required between the fan blade (26) and a body mounted shroud (30). The hydraulic coupler (22) includes driving and driven turbines (48,50) that are drivingly interconnected by means of a fluid (64) operated upon by a plurality of vanes (56,58) located in cavities (52,54) formed in each of the turbines. An anti-friction bearing (28) journals the fan blade shaft (24) in the shroud (30). A universal joint (32) or elastomeric coupler, connects the driving shaft (18) to the fan blade shaft (24) dynamically in any one of a number of relative angular positions. A clutch (20) is included to limit speed of rotation of the fan blade (26) within operational limits.
