Abstract
An elastomeric bushing comprises a first bushing subassembly and a second bushing subassembly each in engagement with an outer surface of an inner component. The first bushing subassembly includes a first inner sleeve, a first outer sleeve and a first elastomeric bumper radially positioned between the first inner and outer sleeves. The first elastomeric bumper includes a first axial flange positioned between a first flange of a first inner sleeve and a first end wall of the first outer sleeve. The second bushing assembly is substantially the same as the first bushing assembly. The first and second inner sleeves of each bushing subassembly are in engagement with the outer surface of the inner component.
Claims20
An elastomeric bushing comprising:
- an inner component having an outer surface;
- a first bushing subassembly including a first inner sleeve, a first outer sleeve and a first elastomeric bumper radially positioned between the first inner sleeve and the first outer sleeve, wherein the first inner sleeve includes a first flange, the first outer sleeve includes a radially extending first end wall and the elastomeric bumper includes a first axial flange positioned between the first flange and the first end wall;
- and
- a second bushing subassembly including a second inner sleeve, a second outer sleeve and a second elastomeric bumper radially positioned between the second inner sleeve and the second outer sleeve, wherein the second inner sleeve includes a second flange, the second outer sleeve includes a radially extending second end wall and the elastomeric bumper includes a second axial flange positioned between the second flange and the second end wall, wherein the first and second inner sleeves are in engagement with the outer surface of the inner component.
An elastomeric bushing comprising:
- an inner component;
- a first bushing subassembly circumscribing the inner component and including a first inner sleeve, a first elastomeric bumper disposed around and directly engaging the first inner sleeve, and a first outer sleeve disposed around the first inner sleeve and the first elastomeric bumper, wherein the first inner sleeve includes a radially outwardly extending first flange, the first outer sleeve includes a radially inwardly extending first end wall and the elastomeric bumper includes an axial flange positioned between and in engagement with the first flange and the first end wall;
- and
- a second bushing subassembly circumscribing the inner component and including a second inner sleeve, a second elastomeric bumper disposed around and directly engaging the second inner sleeve, and a second outer sleeve disposed around the second inner sleeve and the second elastomeric bumper, wherein the second inner sleeve includes a radially outwardly extending second flange, the second outer sleeve includes a radially inwardly extending second end wall and the elastomeric bumper includes an axial flange positioned between and in engagement with the second flange and the second end wall, wherein the first and second inner sleeves are in press-fit engagement with the inner component.
