Abstract
The utility model discloses a plate spring bushing, a plate spring bushing assembly with the same and an automobile. The plate spring bushing comprises an inner bushing and an outer bushing, wherein a rubber bushing is coated on the periphery of the inner bushing along the axial direction of the inner bushing, the outer bushing is coated on the periphery of the rubber bushing along the axial direction of the rubber bushing, and a through groove which is communicated up and down is formed in the outer circumferential face of the outer bushing along the axial direction of the outer bushing. According to the plate spring bushing, the through groove which is communicated up and down is formed in the outer circumferential face of the outer bushing, when the outer bushing is mounted into a plate spring, the outer bushing can be squeezed by the outside so that elasticity crimpling can occur, and the outer bushing is tightly pressed on the rubber bushing and can be in interference fit with the plate spring. Therefore, the plate spring bushing can be prevented from being abraded due to axial rotation after being mounted, and the service life of the plate spring bushing is prolonged.
