  • Patent number: 11833879
    Abstract: A bushing assembly, such as for a vehicle suspension, includes inner and outer sleeves, a bushing disposed radially between the inner and outer sleeves, and a two-piece bar pin. The two-piece bar pin is configured such that a first inboard end of a first bar pin component is received in one end of the inner sleeve and a second inboard end of a second bar pin component is received in the other end of the inner sleeve. One or both of the first and second inboard ends of the first and second bar pin components has a closed end bore such that the first and second bar pin components cooperate to form a closed cavity within the two-piece bar pin assembly for weight saving purposes when the first and second inboard ends of the first and second bar pin components are pressed into the inner sleeve.

  • Publication number: 20220235817
    Abstract: A bushing assembly includes an inner sleeve, a bearing, an elastomeric bushing, and an outer sleeve. The inner sleeve includes two pieces. Each of the two pieces includes a distal end portion and a proximal end portion. Each of the proximal end portions includes an external shoulder having an outer radial face and an inner axial face. The bearing is rotationally mounted around the inner sleeve and captured between each of the inner axial faces of the external shoulders. The elastomeric bushing is disposed around the bearing and abutting the outer radial faces of the external shoulders. The outer sleeve is disposed around the elastomeric bushing and extending at least partially over the external shoulders.
