Abstract
A bushing includes a cylindrical body and a flange extending from the cylindrical body. The cylindrical body has an inner face defining a bore. The flange includes an outer rim and a face extending radially between the bore and the outer rim. At least one groove is formed in the face. The at least one groove extends from a first end intersecting the bore to a second end adjacent the outer rim such that grease supplied to the bore of the bushing is able to flow through the at least one groove.
Claims20
A bushing, comprising:
- a cylindrical body having an inner face defining a bore;
- and
- a flange extending from the cylindrical body,
- wherein the flange includes an outer rim and a face extending radially between the bore and the outer rim,
- wherein at least one groove is formed in the face, the at least one groove extending from a first end intersecting the bore to a second end adjacent the outer rim such that grease supplied to the bore of the bushing is able to flow through the at least one groove, and

3 more elements
An apparatus, comprising:
- a control arm for a vehicle suspension, the control arm having a coupling portion for coupling to a chassis of the vehicle;
- and
- a bushing disposed in the coupling portion, the bushing comprising:
- a cylindrical body having an inner face defining a bore;
- and
- a flange extending from the cylindrical body,
- wherein the flange includes an outer rim and a face extending radially between the bore and the outer rim,
- wherein at least one groove is formed in the face, the at least one groove extending from a first end intersecting the bore to a second end adjacent the outer rim such that grease supplied to the bore of the bushing is able to flow through the at least one groove, and
