Abstract
A planetary carrier includes a first cheek, a second cheek, at least one pin, and at least one bushing. A first axial end of the pin is fixed in the first cheek, and a first axial end of the bushing is fixed in the second cheek. At least a portion of the pin protrudes into the bushing, and a second axial end of the pin is fixed in the bushing. A second axial end of the bushing is free-floating, and the bushing forms at least a first cavity and a second cavity. The portion of the pin that protrudes into the bushing protrudes into the first cavity. The bushing forms a wall that separates the first cavity and the second cavity from each other and at least one stiffening rib extends through the second cavity.
