ABSTRACT:
A center bearing assembly adapted to rotatably support a rotatable shaft on a vehicle frame includes an annular roller bearing that is adapted to receive and rotatably support the rotatable shaft, a support member for supporting the roller bearing, and a bracket for securing the roller bearing and the support member on the vehicle frame. The support member includes a reservoir containing a Theological fluid. A rheological fluid is any fluid that exhibits a significant change in its ability to flow or shear upon the application of an appropriate energy field, such as electrical or magnetic fields. A shear plate secured to the roller bearing includes a portion extending into the reservoir so that axial movement of the shaft with respect to the support member is permitted. The novel construction of this invention includes an effective center bearing assembly support member having variable vibration dampening characteristics which can also accommodate axial movement of the rotatable shaft.
