ABSTRACT:
A vehicle has an engine and a driven differential. This three part type propeller shaft assembly includes a first propeller shaft element, a second propeller shaft element, and a third propeller shaft element. A first joint incorporating a Hooke joint rotationally couples the engine to a one end of the first propeller shaft element. A second joint incorporating a Hooke joint rotationally couples the other end of the first propeller shaft element to a one end of the second propeller shaft element. A third joint incorporating a Hooke joint rotationally couples the other end of the second propeller shaft element to a one end of the third propeller shaft element. And a fourth joint incorporating a Hooke joint rotationally couples the other end of the third propeller shaft element to the driven differential. Two bearing supports, one disposed near each end of the second propeller shaft element, elastically and rotatably support it from the vehicle body. The phases of the first joint and the fourth joint are set to be the same as one another, while the phases of the second and the third joints are set to be the same as one another and to be opposite to the common phase of the first joint and the fourth joint.
