Abstract
An improved bearing assembly is disclosed for supporting a split drive shaft of a vehicle. An inner, rotatable race of a bearing engages the drive shaft and an outer, non-rotatable race of the bearing is mounted in a resilient rubber block. The rubber block, which is connected through a bracket to the vehicle frame, permits limited radial and axial movement of the bearing. The bracket has a flange spaced from the rubber block to the rear of the bearing which limits axial movement of the bearing to prevent the drive shaft from pulling the bearing from the rubber block.
Claims7
A center bearing assembly for resiliently supporting from a rigid support a driven shaft which may be subjected to radial forces and to axial forces in at least one predetermined direction comprising a bearing having a rotatable inner race engaging said shaft, a non-rotatable outer race and a plurality of bearing elements between said inner and outer races, a resilient bushing mounting said outer race, said bushing having first and second sides and an outer edge, a bracket engaging at least a portion of said outer edge and having integral lips engaging said sides adjacent said outer edge, said integral lips retaining said bushing in said bracket, means for mounting said bracket on said rigid support, said bracket further having a flange positioned from said bushing side a predetermined small spacing, said bushing side being unrestrained adjacent said flange, whereby during normal operation said bushing side is spaced from said flange and drive train vibrations are not transmitted to said flange and whereby upon axial movement of such shaft, said bushing side is free to move through such spacing and against said flange to limit axial movement of such shaft.
A center bearing assembly for resiliently supporting from a rigid support a driven shaft which may be subjected to radial forces and to axial forces in at least one predetermined direction comprising a bearing having a rotatable inner race engaging said shaft, a non-rotatably outer race and a plurality of bearing elements between said inner and outer races;
- a resilient bushing mounting said outer race, said bushing having first and second sides and an outer edge, a bracket engaging at least a portion of said outer edge and having integral lips engaging said side adjacent said outer edge, said integral lips retaining said bushing in said bracket, means for mounting said bracket on said rigid support, said bracket further having a flange on the side of said bushing of said predetermined direction, said flange having a predetermined small spacing from said bushing, said spacing limiting axial movement of said bearing in said predetermined direction;
- two dirt shields mounted between said outer bearing race and said bushing, each dirt shield having a generally radially inwardly directed flange shielding a different side of said bearing with one of said shields extending between said bearing and said flange on said bracket, and wherein said bushing has a lip extending over said one shield and forming one side of said predetermined small spacing between said bushing and said flange on said bracket.
