Referring to fig. 1 to 3, the composite bushing 100 of the present invention is mainly formed by connecting two bushing bodies 10 in opposition, wherein each bushing body 10 is processed with a positioning portion 111 to ensure the pressing direction of the composite bushing 100 in the lug hole. The plate spring eye 20 is provided with an engaging portion 21 corresponding to the positioning portion 111, and when the composite bush 100 is assembled with the plate spring eye 20, the pressing direction of the composite bush 100 in the plate spring eye 20 can be ensured by the engagement between the positioning portion 111 and the engaging portion 21. The end face of each bushing body 10 facing the other bushing body 10 is processed with a connecting portion 131 extending outward along the axial direction of the bushing body, and the connecting portion 131 is provided with at least one opening structure 132, and the alignment of the opening structures 132 on the two oppositely connected bushing bodies 10 is ensured by the positioning portion 111 on each bushing body 10. Specifically, when the two bushing bodies 10 are connected in opposition, the two bushing bodies 10 in the composite bushing 100 abut against each other, and when the two bushing bodies 10 are connected in opposition, the alignment of the opening structures 132 of the two bushing bodies 10 connected in opposition can be ensured by the positioning portion 111 on each bushing body 10, which facilitates the entry of a removal tool, shortens the time taken for removal, and improves the convenience of maintenance.

According to an embodiment of the present invention, referring to fig. 2, each bushing body 10 is mainly composed of a first body 11, a second body 12 and a third body 13, wherein the first body 11, the second body 12 and the third body 13 are coaxial, the second body 12 is disposed on the outer peripheral surface of the third body 13, and the first body 11 is disposed on the outer peripheral surface of the second body 12. That is, each bushing body 10 is formed by overlapping and sleeving the first body 11, the second body 12 and the third body 13. In the present application, in order to secure the overall structural rigidity of the composite bushing 100, the first body 11 may be formed as an outer steel sleeve and the third body 13 may be formed as an inner steel sleeve. The second body 12 may be an intermediate steel sleeve formed by a rubber material. Of course, the specific composition of the composite bushing 100 may be specifically set according to the actual stiffness requirement, and will not be described in detail in this application.

In some embodiments of the present invention, referring to fig. 1 and 2, the positioning portion 111 may be machined on the outer peripheral surface of the first body 11, and the positioning portion 111 may extend along the axial direction of the first body 11, and the positioning portions 111 of the two bushing bodies 10 are in the same straight line, so as to ensure that the opening structures 132 on the two bushing bodies 10 are aligned through the positioning portion 111. Thus, while ensuring the pressing direction of the composite bushing 100 in the eye hole, the alignment of the opening structures 132 on the two bushing bodies 10 can be ensured, and the action area of the dismounting tool is increased. Preferably, location portion 111 can be processed into the constant head tank, and cooperation portion 21 on the leaf spring eye 20 can be processed into the cooperation groove corresponding with the constant head tank, and the constant head tank passes through locating pin 30 location with the cooperation groove to be connected, when guaranteeing the direction of impressing of composite bush 100 on the leaf spring eye 20, can also ensure that the open structure 132 of the bush body 10 that two oppositions are connected aligns, and the extracting tool of being convenient for gets into, shortens to dismantle consuming time, improves the maintenance convenience. In the present application, the positioning groove and the fitting groove may be processed into a square groove, and the positioning pin 30 may be processed into a square pin corresponding to the square groove (see fig. 4). In the present application, the positioning portion 111 and the engagement portion 21 may be directly processed as a positioning shallow groove to position the press-fitting direction of the composite bush 100, and if the positioning portion 111 and the engagement portion 21 are processed as a positioning shallow groove, the positioning pin 30 is not required when the composite bush 100 is assembled with the leaf spring eye 20. In this case, since the positioning pin 30 cannot be used, there is a possibility that the composite bush 100 may move in the circumferential direction of the lug hole in the plate spring eye 20, but the applicant has proved that such a movement error is within an acceptable range and does not affect the assembly use of the composite bush 100 with the plate spring eye 20.
