Abstract
An elastomeric bushing assembly has an inner component, an outer component and an elastomeric bushing disposed between the inner and outer components. A bearing engages the inner component and is disposed between the elastomeric bushing and the inner component. The bearing allows pivoting of the inner component with respect to the bearing. A low friction coating is disposed between the inner component and the bearing to provide a low friction interface.
Claims18
A bushing assembly comprising:
- an inner component;
- an outer component disposed over said inner component, said outer component including a first curled end and a second curled end opposite to said first curled end;
- a single piece elastomeric bushing disposed between said inner component and said outer component, said entire single piece elastomeric bushing being disposed between an outer surface of said first curled end and an outer surface of said second curled end;
- and
- a bearing in engagement with said inner component and disposed between said inner component and said elastomeric bushing, said inner component being free to move with respect to said bearing;
- wherein
- said single piece elastomeric bushing forms bulging portions that seal against said inner component to seal the engagement between said bearing and said inner component.
